macOS Monterey on Unsupported Macs [2008-2015] OpenCore Legacy Patcher!!!

[@stefanocanavese6102]

Never been a KZbin commenter but this time my selfishness wasn’t enough to not show my appreciation. Very few times have I come across a tutorial so well articulated and easy to understand. I gave life back to my 2011 iMac that would’ve kept collecting dust for decades to come. It’s infuriating to think how Apple strategically restrains you from updating your old systems so you would buy their new ones. Truth is, Monterey runs smoother than ever in my 10 years old mac and I couldn’t be happier to save money instead of fuelling Apple’s wasteful system. Kudos to you! 👏

[@tomc7018]

well said

[@Jellowstudios]

He's right

[@computernerdinside]

I assume you’ve upgraded your hardware to an SSD and more RAM? The average user doesn’t do that, and I think that’s why updates get cut off after a certain point. I can’t imagine it would run well on a spinning hard drive with four gigs of ram like you find in those older systems by default. Edit: tried 4GB of ram in my 2012 MBP, with an SSD, and maaaaan was Catalina much less responsive, my guess is due to the page file being used quite a bit. Went back to 16GB lol

[@stefanocanavese6102]

Thanks so much for creating this video. It saved a perfectly adequate 2011 27” iMac from landfill as its last supported MacOS, High Sierra is too old for many of the major application vendors to bother with. Followed the hardware disc and memory upgrades and the video was just perfect to lead through the patch to upgrade to Monterey. I simply wouldn’t have done it without Mr Macintosh’s’ guidance. Now, my “useless” Mac is perfectly adequate/fast for every day to day tasks.

[@limafabioo]

Same here pal! Mid 2011 27" Imac, Same Machine, saved from trash thanks to a combination of guides. This guide, was the last step ( Software ). If you can and have the same machine, spend a couple of Euros and Upgrade it, mine feels like a brand new machine! 32gb ddr3 (4x8gb) + Nvidia Quadro K1100 (2gb) + 512gb SSD, been using for graphic design works like a Charm, only thing left to update is the airport card ( but since i dont use airdrop, it doesnt really make much difference to me ). Long Live Mr Macintosh!🏆

I literally just completed updating my 2012 Mac mini to Monterey 12.6 using your guide, went by with zero issues. The latest OCLP 0.6 is a beast and makes everything much easier than before! I updated my 2012 MacBook Pro to Ventura earlier this year as well. I'm so grateful that OCLP and your channel exists. These machines are still capable and it's nice to be able to breathe life back into them. I'm not your "perfect consumer" and I always use the stuff I buy until I really can't use them anymore.

[@arjay535]

I know another individual said this but I too was so impressed with this full walk through. Our 2011 iMac hadn’t been used for some time (ahem.. maybe 2-3 years) and I was a little disappointed to find that some software we now wanted to use did not run on the OS and of course the standard updates no longer offered a path forward. A couple of hours investment and we now are back in business. Thank you Mr Macintosh and all the OpenCore support folks. More è-waste avoided for a little longer.

[@Alonelycreep]

Finally, someone who does a good walkthrough. 1 thing: if you don’t have a boot screen compatible GPU: before installing Monterey, remove all drives BUT the USB installer from the Mac and reset the NVRAM. It will then boot from the USB.Then turn it of, add SSD and turn on, you can install on your ssd

[@jessicadean1560]

It worked like a charm for my mid 2009 MacBook Pro. I added more RAM and put in an SSD over a year ago and my computer has been working better than ever so I was very frustrated that I wasn’t able to use it for certain things because of the outdated OS. Buying a new MacBook seemed so wasteful considering how well my old one works. This was exactly what I needed to get more life out her. Thank you so much!

[@oldlavygenes]

I have a 2009 Macbook Pro as well just lying around. I've been playing around with some Linux distros to revive it. My favorite so far has been Pop OS. The problem I have though is compatibility with the nvidia graphics causing weird issues like some apps crashing and other functionality not working. I'm wondering if I should give OCLP a try. I'm curious about your experience running Monterey on it. Are apps and animations sluggish? Are there limitations?

[@MichaelChmilar]

OCLP is the best way to get an unsupported Mac updated to MacOS Monterey (and hopefully Ventura, when it arrives), and Mr Macintosh provides the best instructions on how to install. He goes quickly through the information, but he is thorough and comprehensive. I recommend watching the instructions from start to finish before you try OCLP for the first time, and then go back and follow the steps that you need for your personal machine. I've been using OCLP for a while now on a Mac Pro 5,1 (2010). My machine has a Radeon RX580 graphics card which has the Macintosh ROM flashed by MacVidCards. I also replaced the WiFi and Bluetooth hardware cards with a more recent card from an iMac (I bought a kit on the auction site that provided the card, some cables and connectors, and instructions). With these two hardware upgrades, my Mac Pro has Metal-compatible graphics card and supported WiFi and Bluetooth, so OCLP does not need to install any legacy root patches. One nice advantage to OCLP over other patching methods I had used previously for Big Sur is that my Mac Pro now receives and installs Monterey updates (including Beta versions) using Apple's standard Software Update. Before allowing Software Update to install an update, I check youtube to see if Mr Macintosh has installed and tested the update and verified that it has no problems.

[@Mr.Macintosh]

Michael, thank you very much! You called it on your Mac Pro, it is in a perfect spot with an updated wifi / bt card & metal graphics card! It should continue to run well into the future. I hope the OCLP devs can get Ventura working 🤞

Thank you so much for this! I was able to transition from Mojave to Monterey with my Mac Pro 5,1! It must be stressed; if you have ANY PERIPHERALS, multiple monitors connected to the GPU (I have three monitors to my RX 580), internal USB 3.0 cards, etc., DISCONNECT ALL OF THAT! I Cannot stress that enough. All you need is the barebones of the system, USB keyboard and mouse, and one monitor to make this upgrade work. Trust me, it will save you time. Also, if the OPTION key doesn't work with the restart to see/choose the other drives, do CMD + R (Recovery). The OPTION, never worked, period. I had to CMD+R, run the TERMINAL, DISABLE the SIP, restart, Boot back into Recovery (CMD+R), run TERMINAL again to mount the USB EFI, bless it, and restart. I hope this helps anyone who had trouble.

[@trabseyn8000]

Did you bless the EFI volume or a specific file within the contents? Running Martin's OC with a 580 and get stuck before the boot picker. Took a stab with the bless opencore script used to get Lo's OC working but it just presented 2 USB EFI in the boot picker, neither was bootable.

OCLP balked at first using the MacPro configuration but I was able to get the install to proceed. Transferred the SSD into the MacPro and ran post install patches to get the wi-fi running and tweak the spoof level to get best performance out of the 580. Worked a lot better than yanking all the cards out of the MacPro and tinkering around with Terminal. The only software that won't run under Monterey thus far is X-Plane 11. Parallels VMs, Docker, Davinci 18, running quite well. When first running the setup on the Monterey install take the time to set up your iCloud. Your other iDevices will alert you login on a new Mac. I bypassed this process upgrading the girlfriend's Mini (she got a better machine out of the deal) and the preferences on her Monterey install would not take. Had to repeat the clone Catalina, OCLP upgrade to get that system up to speed with Monterey. Frustrating upgrade but worth it.

Holly Molly, this video is so detailed oriented that I am both super excited and anxious to try to upgrade my 2010 Mac Pro 5,1. I had tried in the past to update to Catalina with no success and I got so frustrated that I gave up. It was much too time consuming with no result. This was about 2-3 years ago. Over the years, I had fully upgraded my CPU, GPU, Memory, HD to SSD very high capacity etc... absolutely everything one can imagine and was stuck on Mojave...

The explanations are clear and precise. I consider myself successful in installing, via clean install, the latest Monterey build on my MacBook Pro 15 Retina, 15-inch, mid 2012 (10.1 model), which still works great. The Monterey is smoother and a little faster. I believe, I appreciate it. Everything works well. I repeat myself - everything (or almost). The only concern is that some applications constantly quit unexpectedly. Uninstalling and installing does not change anything. Like, for example, ExpressVpn, which has a particularly strange behavior. It opens correctly, but as soon as I press "Connect" it quits unexpectedly. Strange, right? Do you have an idea or suggestion to give me so that I can solve this problem? Thank you very much in advance.

I tried everything under the sun until I came across this video, now I'm running Monterey on it! I don't usually leave comments but signed in specifically to show my appreciation.

[@gabrielgjercic]

Thanks for your extraordinary work, it always impresses me how professional you are. Thanks to you i’ve been keeping my Late 2013 21.5’ iMac with an upgraded SSD always up to date for years, first with Patched Sur and now with Open Core Legacy Patcher. I wanted to ask you something: when I updated to Monterey with OCLP some months ago, I did it as an upgrade having Big Sur (that it was done thanks to Patched Sur), and even though it has worked amazing, being able to enjoy all new features flawlessly, I’ve had to deal with reaaaally long booting times every time I turn on my Mac (that I didn’t have with Big Sur nor Catalina) and once in a while it can do some funny glitches that i can fix them by rebooting the Mac. So I was wondering, can I do a clean install to try to fix this issues using this process even though I’m already in Monterey with OCLP? Thanks and greetings from Chile!

[@Mr.Macintosh]

Hello Gabriel! Thank you very much for the comments 👍. For your situation, I would reccomend a a full PRAM Reset, Erase and fresh install of Monterey. This would remove all previous parts of any other patcher and give you a fresh start. Let me know how it goes!

[@andrewsgoodman]

Thank you so much for helping me install Monterey on my old mbp late 2011. I am loving this .

[@ricoquintana9230]

After watching your video tutorial. I was able to successfully install Monterey on my 2010 MacBook Pro 7.1 using OCLP. Thank you very much! Keep up the good work!

[@DavidWise]

This has been without a doubt the clearest and easiest tutorial I have ever watched. Excellent work! I now have Monterey running on my Early 2008 Mac Pro!

[@ronreidjr]

I am not a techie and would dread this type of operation and after I almost begged two techie friends who were unavailable I had to try to install this patch with OPENCORE. your patience in crafting this video allowed this 2012 Mac book air belonging to my family to have life again. many thanks for having a simple to follow ( I had to rewind it a few times). But everything in it worked (even with different versions). hats off to you Mr. Macintosh. Can you do a vid about AI next?

[@mvrck-pb5pk]

This is - as from today - my ultimate update/grade tutorial channel for my cMP 5,1 (mid-2012). First shot, direct hit! Thank you so much for your dedication to the Legacy Mac Pro's. Running macOS Monterey 12.6.2 without any bleeding, all systems are go! Cheers.

[@mvrck-pb5pk]

09/20/2023 still running as a smooth operator and updated my cMP 5,1 to Monterey 12.6.9. Stunning performance by the devs & Mr. Macintosh channel.

[@chriscole2780]

I just seamlessly upgraded my late 2009 iMac. Was frustrated that I couldn't upgrade it to Monterrey. This video saved me so much frustration. Well done and thank you!

[@abassimusic]

Unbelievable!!! This is what you call a tutorial. Just completed the installation of Monterey on a Mac pro 5.1 2009. Works like a charm. Thanks so much Mr. Macintosh

[@HugoScavinoUSA]

Thanks!

[@oldfool5857]

This video in particular, plus another showing how simple it is to upgrade these older macbooks convinced me to buy a 2011 model and upgrade. Total cost £198 GBP, I now have ‘modern’, fast and cavernous Macbook Pro... a huge vote of thanks and appreciation for all your hard work and professionalism. Having a great Macbook Pro AND up to date OS has given me just what I need, for a fraction of ‘new’ cost. Now I can’t leave my ‘new’ Mac alone! 😂

[@Mr.Macintosh]

What a deal! The 2011 MBPro is a great computer and still a fast Mac 11 years later 👍

[@ManuelPicanco]

just install macOS Monterey on my late 2012 Mac mini server and it works like a charm. Thanks to your step by step setup guide. My Mac mini has a new life!!! Thank you sir!

[@scorpio4080]

I've watched several of these types of videos describing this process. You're the only one who walks a user though completely. Well done !

[@angelo_d]

Successfully installed latest OS (2023) on mid-2011 iMac with SSD following your instructions. Amazing. Only hiccup was that the Bluetooth Mac mouse can’t be used during the restore/install stage so make sure to have a USB mouse handy. Was possible navigating with keyboard only, but was not easy! Thank you for this great video 👍🏼

[@devaggarwal2506]

Never done a comment before but thought I should do it for this. Thank you for going to the extent that you did for research and details. Worked like a charm!

[@omc]

Thanks for the tutorial! It really helped me, I was stuck on BigSur in a 2014 mac mini Even though Monterey was officially supported for my mac mini, it had problems booting and in the initial setup, watching your video I think I can pinpoint the problem, it was the graphics (the wallpaper even had artifacts). Using the official way the graphics wouldn't load properly, I was stuck in the setup in the set username/password screen. The only option was to boot in safe mode, it was slow, the graphics really struggle, but in the end it worked, I could create the user account. After the user account was created and the OC patched the graphics (16:58) it just worked! Thank you !!

[@MS-zi2ft]

You are the BEST! Followed your instructions to the "T" but had an error with OSX 12.6.3 on an 2014 MBP running Mojave. I ran open core again and picked an older version on Monterey and all went PERFECT ! No patches needed with this open core version! Doing a time machine restore now .. Great Video ! You Rock! ! Thank You!

[@mairajzafar]

My Man... the way u describe all the procedures is awsome... many thanx.. my old mac git a new life.

[@Bitq1_Cole]

Thank you Mr Mackintosh I just bought a 2009 MacBook Pro of eBay and I installed Big Sur using this guide aswell as your other guide. Works flawlessly, thank you so much.

[@bdphourde]

You're not an AI bot, are you? Normal YT creators aren't anywhere near this good at everything! ;) This service to us to extend the lives and usefulness of our beloved Macs is invaluable! Thank you so much! When I grow up I want to learn to be just like you! ;)

[@oatsmania]

Wow the best detailed KZbin video I’ve seen so far and thank you. I’ve followed all your information and my MacBook is working super fine. I decided to install from scratch and I can book up perfectly without a usb. You are the best and thank you.

[@SecretplaceintheGlory]

Dude, this worked for me! On my iMac 2011. I had to do a clean install, so I backed up everything to a jump drive and then just jumped in. I am almost 40 years old. A boring old mommy of 5, and so basically if I can do it, anyone can do it. God bless you sir, in Jesus' name. You have saved me thousands of dollars.

[@esmithey5]

Outstanding how-to and explanation for the use of this wonderful software - I had attempted a couple of times to install Monterey using 0.5.3 but the procedures I followed were incomplete and I wasn't able to get the os installed correctly - Your step by step process made it easy and manageable!

[@luiarhs]

I'm so thankful with you guys! I recently install a metal graphic card on my iMac 12,2 and finally can run Monterrey like a charm. Definitely, you're the best!

[@grooveroid]

After a few slight hiccups where the process to boot without the USB wasn't automatic ( just run the patcher again but perhaps don't remove the usb on reboot) it's now working like a charm on a 2009 white unibody. Thanks very much for this excellent guide!

[@ahirst]

This tutorial rocks! I am so pleased with the result. I actually managed to upgrade my Early 2009 White MacBook to Big Sur with thanks to this video - and after the post-install patches are applied, honestly, it runs great. Thank you! :)

[@phillipmeza3459]

Mr M, Thank-You so much... My 2012 Mac Mini (2 SSD's/16gb ram) is again my go to Machine, shelved for about a year, did a "maintenance" routine, (CPU paste & fan clean) and did a "clean" install of Monterey from Catalina. The Mini with Monterey is great, all these new features and now I can use my iPad pro 2018 as a 2nd display running my Roon install, and go to "widgets". Your tutorials are great, keep up the good work. Phillip

[@U.S.ArmyVeteran]

As others have stated, Mr. Macintosh you viseos are easy to understand and follow unlike some of the others and I appreciate you so much! Thank you, thank you, and thank you! I'm sending a Thank you donation right now.

[@ExplorewithHAROLD]

I bought a used MacBook Pro 13 (Early 2013) and I want to thank you for this tutorial because it has enabled me to update it.

[@philippemartignier9858]

Many thanks, so clear explanations! And the tone of your voice gave enough confidence to try it :) Everything ran as in your video. Best tuto ever! Congratulations!

[@garyhearne09]

Hands down the best tech tutorial I've seen on youtube. Made it all very straight forward and explained every step. You need to add a donate button somewhere here as you are saving people a fortune. I resurrected a Mid 2010 27" Imac with SSD that would have been fit for the bin now it runs like a dream.

[@windsurf03]

When I go to open core the Assets will not open. Did u have this problem

[@michaelharmon8731]

Thank you!! Very well done. Thanks to you and the devs of OpenCore Legacy Patcher I was able to install Monterey on my 2009 classic Mac Pro. It works great. Honestly it's faster now with Monterey than it was when running Mojave. I did break my Contour Design Shuttle Pro hardware compatibility, but that 's the only issue.

[@Mr.Macintosh]

Great to hear Michael! I've noticed the same, Apple did refine the code for faster system tasks and booting 👍

[@petrov8086]

Thank you, Mr. Macintosh. Now my late 2008 MacBook Pro is reborn with your patch. I have noticed that (vs El Capitan) performance is slightly slower, which is expectable if machine uses Core 2 duo CPU :) but the amount of advantages of Monterey against El Cap says everything. For those who want to apply patch to a such machine you may bump with the situation when installer says "less than minute remaining" and seems hang, LEAVE IT AND LET IT ACCOMPLISHED. In my case this particular step took 2 hours or about.

[@Protonishpk]

Hi, did you upgrade anything or just straight on continued with the installation?

[@avidadaloira5660]

Thank you so much Mr. Macintosh. Just got an iMac mid 2010 (hardware 4GB) and it had MacOS High Sierra but of course I couldn't had any updated applications. Yesterday I took your tutorial and today I've macOS Monterey running perfectly on the iMac.

[@zachdscott]

Thank you so much! Got 12.6.x on my new hard drive now with a new battery and 16gb too. Mid 2010 mbp. So happy I repurposed my late Grandpa's old mbp. Tysm!

[@Mr.Macintosh]

Awesome @zachscott1089 !!! Keep that 2010 running, your grandpa would be happy for sure ❤️

[@supernormalizedpodcast]

This saved me buying a new mac! My old mac was good but the newer software was uninstallable. Thanks so much for this detailed walk through... changed my life considerably!

[@LuciferCelebrimbor]

I do not know how much I should thank you... So far, it is the very best tutorial on KZbin...

[@rocknwroll]

How much time could one expect an experienced computer repair tech to spend on this? the approximate start to finish time in minutes to install new os on a unsupported, pristine, 13" late 2011 MacBook pro holding 180 GB data, 16gb ram, using these steps and tips by a highly trained person, using high speed ssd and minimum 100mbps internet connection. Someone who already knows all this and has done it many times before. Someone like you, thank you. I really appreciate any kind of an honest guesstimate you can give. I love this old thing and don't want to turn it into a bookend. Thanks again.

[@shadowgunner69]

Just wow! Great video. I have a 2011 MBP and need to install Pages, This is a clear and concise walk-through. Subbed.

[@t3h_M05]

I want to say thank you for the walk through. Mid 2012 MacPro5,1 w/ EVGA GTX60 Mac Edition, Upgraded Wi-Fi/BT card, OWC Mercury EXTREME Pro 6G SSD 1TB, 32GB RAM. The fresh install went flawless and everything works the same. =P

[@syedrafaqatali4779]

Thanks man ! I have mid 2009 macbook pro 4GB RAM with 160GB SSD. updated it to 12.6.4 and it is working fine. It is not legacy it is OpenCore Miracle Patcher. Stay blessed all who contributed to this.

[@andypodmore6721]

Thank you for this excellent walk through. I' have a 2014 iMac and have just installed an external SSD drive, as it was running so slow on the internal HDD. I am curently running Big Sur, but after trying to update to Monterey, it kept failing, as now I found out my machine is not supported. I need to update to ver 12 MacOS to continue to run and get updates for Autodesk's Fusion 360 software, as they have just come out saying that from March 2024, anything below MacOS 12 will no longer be supported and no updates will be available. Think you just saved my bacon/sanity lol. Again, a BIG thank you. Got yourself a new subscriber

[@LouieGonzalez-xe2ll]

Thank you partner. I had done this before but I had forgot. I was able to download the latest version of the open core legacy patcher which removes a couple of the steps on your version. worked well. Thanks again. great video

[@Keeping-It-Real-55]

Thanks this helped me a great deal. I went from big sur and had issues with internal sound, and apple maps. To Monterey even though I could of installed ventura I went this route and its working great. Appreciate the great explanations of everything. Hands down the best tutorial.

[@ihatereigen]

thank you thank you thank you!!! seriously i cannot relate to the comments enough because this is really the most helpful, detailed, step by step guide there is!! i was really desperate to play some games on my mac (a childish but genuine reason 🙏) and now i can finally do it. so so grateful

[@SetTheExample36]

This just worked for me in 2023 from high sierra 💪🏾💪🏾💯💯

[@PrometheusAndBob]

This was the greatest KZbin video I've come across all year. Thank you so much for your dedication, time and work.

[@valramos2003]

For 2008 iMac, after doing a clean install (erase in disk util then install Monterey) it boots back into the black setup screen with install from Time Machine, Install or Upgrade, Safari for troubleshooting, and Disk Util. I never see the auto-selecting of Macintosh HD.

[@valramos2003]

@@JacobGeleyn Hi, check how much ram you have. In a different video, it was suggested that having less than 8gb might be the cause for Monterey not installing. That particular iMac I was having trouble with had only 4gb. I settled with Catalina via Dosdude1 method.

[@brylec15]

I cannot overstate how happy i am thanks to your guide - such an amazingly simple, yet informative video!

Dear Mr. Macintosh, I am as many others a huge fan. Thank you for the work you put into these tutorials. That said: my Mac Pro 2008 NVIDIA won’t boot after bless command, will not show boot picker with Alt key. Any ideas?
