Hey Dosdude1, just wanted to thank you for your extremely brilliant and professional work creating and delivering for free this macOS Catalina Patcher. Let me tell you I waisted a lot of time trying to install Catalina on my MacBook Pro mid 2010 (7,1) using Open Core Legacy Patcher (OCLP), but it is extremely slow and unstable compared with your solution. You are allowing lots of people to continue using their old Macbooks without wasting money and resources that not everyone is able to afford, and that's a noble labor! Thank you again.

[@DialloMoore503]

Hi. I followed all steps and it says that the installation was successful. But after I restarted it, it shows that it’s still on the old operating system.

First and foremost, a trillion thanks for the extraordinary guidance-truly, you've worked wonders. Managing to upgrade to Catalina on my vintage Mac Pro 5.1 was nothing short of a revelation. I've yet to encounter a single hiccup; it's smooth sailing all the way and astoundingly, it's outperforming High Sierra. Monumental kudos to you for that! The tutorial you provided was nothing short of a masterclass. One attempt was all it took to get everything in order. It’s absurd how Apple overlooks the potential of older models when, clearly, these systems are perfectly capable of running more modern software. As someone knee-deep in 3D modeling and web development, I can definitively say their 'incompatibility' claim holds no water. So, really, an ocean of gratitude for dispelling that myth and for making my work and life remarkably easier and better.

[@alankolski9766]

Thanks for your work! Got a mid-2010 MacBook Pro from my son-in-law. had Sierra installed and updated to High Sierra. Following your video I recently upgraded to Catalina and it works great! With added memory and SSD, this old MacBook will live on! Thanks dude!

Just installed on mid 2011 Mac Mini - 2.5GHz Dual-Core Intel i5. Also recently upgraded to a 500GB SSD and running 16GB of DDR3 RAM. So far, so good! I upgraded from High Sierra. Thank you!

[@xorgbeep]

Anirudhh Raghavan your gpu doesnt meet the requirements for metal, and supporting your gpu could negatively impact metal preformance on more recent hardware. EDIT: one could argue that just having OpenGL as a fallback for the entire OS and officially supporting older models is the way to go, but for most people running even 10.11 is fine. About the same support as windows 8 at this point

[@Angelraya]

[@macdaddyo998]

I cannot express my thanks enough to equal the value of what you have done for me and my 2010 Mac Pro 12 core, and how you, *alone*, have preserved and extended my significant investment in Apple hardware and Pro software that Apple has deliberately abandoned, and painted me into a "can't get there from here" corner under Mojave.

what GPU do you have on your 12 core? nVidia? i have a TITAN X 12 gb on my 12 core. do you think this would work? most of these patches want an AMD card like the AMD 580 8gb.

[@macdaddyo998]

Update to my comment above: I have upgraded to OpenCore to enable unsupported OS's on my 12 core Mac Pro 5,1. This enables me to run a multi-boot set of unmodified, un-patched OS's, including everything from Mojave to Monterey *and* Windows 11. Catalina Patcher was great when it was the only game in town, but times have changed. I'm still grateful to dosdude1 for showing me what is possible on this old heavy iron, but I no longer recommend Catalina Patcher to those looking to extend the life of their Mac Pro 5,1. Best wishes to you and yours...

Last year I tried to install the Catalina patcher on my old macbook and imac 2011. They were installed but the screen was pink and flickered. I tried many times and always got the same results on both macs. I had to reinstall the High Sierra and wait for future solutions. Now my apps werent running on High Sierra anymore. I needed the Catalina. So I tried to install Catalina last month and went perfect this time! Both old macbook and imac are running Catalina and many apps are running now, which werent running on high sierra. I noticed that increase and decrease brightness were disabled. And sharing screen was also disabled. Today I ran the patcher using Video patcher and AMD metal patcher. Everything works fine. Thanks and congratulations on your initiative! Saved both of my old macs. Ps: whoever tries to install any OS, always backup your data first to a external hard drive.

Hello! I just bought a used iMac 2011 and after i noticed it's running Catalina with dosdude patcher and the graphic acceleration us s@cks. I wanted to put back the original High Sierra from bootable usb, but it's impossible, it looks like there is no recovery partition or i cannot reach it. Not even with the keyboard shortcut at boot. How you make it work? With the latest dosdude Catalina patcher 1.4.7? Actually i would prefer to put back the factory os with factory recovery. Do u have some advice? Thanks.

@@laszlocsikos189 hello! 1) how many GB of RAM are you using? I am running SSD with 8GB and graphics working just fine. If you use Hard drive, it becomes really slow. 2) if you have bootable high sierra, you should put flash usb, start mac and press option until boot screen appears. And then select your flash drive. 3) if tip 2 doesnt work, power on imac and press "option shift command R" until you see the internet recovery screen. Let me know how it goes. Good luck

All the downloads say you have to have 10.15.0 before the stuff from Apple will work.

Update: ​Unfortunately i have been experiencing many stability issues with "Catalina". I tried installing "Mojave" too (thought maybe it would be better and more stable) but still similar issues. Simple tasks like using Microsoft Office are hard to use with stability. MS Office for example keeps crashing or cannot write (stops responding on my typing). The computer needs restart. No serious issues when exploring the internet though (I'm using Chrome & Mozilla Firefox). It is worth upgrading if you need a machine to mainly surf the net and be able to visit any website. Congratulations on your magnificent work! I managed to install Mac OS Catalina on a MacBook Pro 13" Mid-2009! Haven't checked everything yet but so far seems very good!

[@flamingkillermc2806]

Abdullah Bulut What do you mean? The patcher updater *like nightshift patch*? I’m pretty sure @Walter meant the version of the *OS* not the patches. So Walter is right, the only way to update from Catalina *10.15* to *10.15.1* is to use the latest Mac OS Catalina patcher and then download the latest *10.15.1* then install directly to the machine without making an bootable drive.

[@flamingkillermc2806]

Walter Yeah it’s the only way do to Dosdude1 making it so you cannot update through the *software update* tab in system preferences. He made it like that since if you would have updated through system preferences it would have broke the whole OS and you would have to reinstall. I know this since other people with supported machines with Catalina, go to the AppStore links to install an older version like Mojave to high Serria, but it works for them, but not us. The software tab in system preferences will deny and say that it is up to date *even though it’s not* but also denys the download of older OSX’s saying it cannot find the update while people with supported machines are able to do it properly.
