How to Install/Run OS X El Capitan on an unsupported Mac Pro

[@jtdiffen]

This was just awesome! I followed your instructions explicitly, and did not have a single complication. Followed the 2,1 upgrade with 32GB of ram, and am now migrating my old data and apps using Migration Assistant and a Time Machine backup. What an excellent use of my venerable Mac Pro. We've given it a new lease on life, and I love how fast it boots, and it is absolutely silent now...no fans, now drive whirr, just silence. Thanks a million!!!! Drift

[@brunnerb]

It works! I placed the El Capitan hard drive in the Mac Pro, removed the internal drive with OS X 10.7.5 and the internal backup drive and BOOM, it booted into 10.11.5 like a charm.

[@themadmattster9647]

hey, i've got a backup drive with actually Mavericks already installed, any idea on how to gett that to work?

[@nightbeat1media]

Out of the many video's I've watched, yours by far is the best in getting it done.. Awesome job at explaining. Thank you!

[@kennek6404]

Thanks for the Bootable USB Drive Creator! Came in handy as well as installing OS X on my MacBook and putting the SATA disk on the Mac Pro. Thanks for taking the time to make the video with Pike's bootloader!

[@dreamnight-mq1zg]

You are the man!!! Saved my a$$!! I was looking everywhere and no one was able to show how to do this. You explained it perfectly! Thanks man, you’re awesome . Keep up the great work!

[@CorbinElliott]

It's alive!! You are a life saver otherwise the Mac Pro 1,1 I picked up would be a huge paper weight with Lion installed. UGH!!!

[@hetrickaj]

Did everything you told to do and it works very well! I have tested it and works with the apple x1900xt and a gtx 260, didn’t have to flash the gtx 260 at all either. Thank you!!

[@Newjacknino216]

Ok finally had everything running correctly but i left and came back to a green screen with black vertical lines what do I do?

[@paullangton-rogers2390]

What made this easy peasy for me (after MANY failures with flash drives) is two things which cost me just $23: 1) a cheap 120GB SSD drive plugged into my Mac Mini as an external drive rather than using a flash drive and messing around swapping out hard disks. 2) A cheap as chips USB-to-SATA connector off eBay which plugs onto any 2.5" SSD/SATA-HDD (no drivers needed) it has two USB connectors which plug into your Mac USB ports (one provides power to disk drive the other data connection). This method is quicker because your SSD/SATA drive serves as both boot installer drive and also installation drive if you make a small 16-20GB install partition on it and use the rest of drives space for your MacOS installation partition. It''s very fast to do and install using an SSD as both your install media and installation target rather than using a flash drive. One drive, one cable, and the 32-bit EFI bot.efi file copied onto it after. job done. This method is a LOT quicker and far less hassle/risk of wrecking your Mac taking out hard disks. The USB-to-SATA connectors ONLY work with the lower-powered 5v 2.5" disks not a full-size SATA disk which need 12V so go for a 2.5" disk and SSD is a hell of a lot faster and more reliable than SATA magnetic and they're very cheap now anyway.

[@Onlypcgaming]

at 5:21 mark, how long did it take for the install drive to boot up? During this period, is the Apple logo the only thing you will see?

[@colourofmagic]

Just got a 2,1 today myself and am in the process of getting it to work.Cheers!

[@giant-killer6360]

I want to thank you for your video. I used a 3.1 Mac Pro to set up the drive. My only issue were the two boot.efi files. I had permission issues in 10.6 trying to get rid of them and replace. But I also have 10.7 and 10.11 running on the box as well. I went into 10.7 for one of them and 10.11 for the other. Now the drive for my Mac Pro 1.1 is ready. I have not tried it yet but I'll let you know. Thanks again!

[@gabakusa]

I have done all that but in a SSD, and it still does not boot. all I need is the ?? icon. I did not replace the video card, do you think maybe the Mac Pro wont work with SSD or is it because the video card. thanks your time

[@dosdude1]

Hold down the Option key at boot and make sure the drive shows as a boot option. If not, you may need to re-install.

[@cdred71]

Thanks for the GREAT tutorial. My Mac Pro 1,1 with 16gb memory and 2x dual core Xeons runs El Capitan and Logic Pro X BETTER than my late 2012 Mac Mini with 16gb memory and dual core i5. Sound actually works. Go into system preferences/sound and choose sound output.

[@dosdude1]

Grad, glad you got it going!

[@djazzyp711]

still doing a great job in 2020 thanks so much dosdude

[@jochemvangalen9464]

how to use the USB Drive Creator

[@geefizzgeefizz2857]

What graphics card did you use dosdude, I can see it is a 2gb card, I want to also get something like yours

[@dosdude1]

It's a Radeon HD 6670, but you can use pretty much any PC graphics card.

[@matthewpianisto]

Can I use this thing with MacBook 2007 (OS X 10.7.5)?

[@markneal9177]

thanks Dude!! had an old mac pro lying around and had never used it nor been able to..till now!!! its amazing "when" you follow directions

[@renragged]

Thanks for sharing. I followed your instructions using a Firewire connection to my old 2007 Mac Pro and it seems to have worked perfectly! It had an ATI Radeon HD 5770 1GB in it and that graphics card worked fine. No need for me to get another one. That was a relief.

[@renragged]

Of course after I installed the security update and restarted it wouldn't boot up... I had to replace the boot.efi file again, but after I did that it worked fine.

[@dosdude1]

Yeah, you'll have to do that with every Security Update or 10.11.x update.

[@renragged]

Thanks. Hopefully I remember that... :P

[@jimlad01]

Thanks very much for taking the time to make these videos and to help others, greatly appreciated. Assuming we're working with the said 2006 Mac Pro, 1,1 could you share your thoughts on; 1. Will USB, Bluetooth and wireless work as previous - or will they need to be upgraded? 2. Is it possible to flash an ATI Radeon Sapphire HD 5870 - or any 'non mac' GPU in order to get the boot screen / startup manager? 3. Will the installed El Cap load If you have other OS's on say two or three internal hard drives, (and you've selected it as the startup disk) or will you need to disconnect these first? Again, thanks a lot.

[@winstonbanks1057]

Where do I download captain from

[@stevearkwright]

drive.google.com/file/d/0B4wuh1-MGP4yUHdFM3U2WEdoRzQ/edit

[@cramirezalberta]

This is the easiest way to do it. I have encounter a problem, every time i upgrade the system software i have to add the efi. file again. So far everyting works up to the latest mac os 10.11.6. Thanks to all the people involved.

[@cdred71]

The only thing now is to figure out how to modify boot.efi on recovery drive so that I can disable SIP to run some apps that require it to be off. After a few days, all is running good with no issues. Mac pro 1,1 with 16gb memory and Mac flashed Radeon HD 5770.

[@dosdude1]

Just mount the Recovery Partition using Terminal (run diskutil list, find Recovery HD, then run diskutil mount /dev/diskXsX). Then you can access the partition and change the boot.efi file.

[@cdred71]

Thanks. Just what the Doctor ordered.

[@colawin]

now u can try to install macos 14 to the mac pro 2007

[@jocvel]

How long it will take to boot up the first time??

[@twdetailing]

so if I don't have mine flashed to firmware 2,1. Do I need to flash it to 2,1. Can I flash it if I didn't change the processors? Or lastly can I just run the 64 on 32 patch, or is that what installing that new boot.efi does for me?

[@JaviBello]

After install on my Mac Pro 1.1 (flashed to 2.1) with 2xquad 3.0, 12gb RAM and 512mb Nvidia, everything works fine except USB ports. Only work keyboard an mouse, but only if are connected before turn on the computer. If I unplug and plug in again, doesn't work anymore until I reboot. No other USB stuff work(hard drives, printers, pendrives), also doesnt show on system report. Any clue? Thanks

[@JaviBello]

FIXED!! After weeks of trying all kind of things, pulling my hair out, and thinking of throw out the window mi old MP, a few minutes after asking you, i read a guy saying it was a hardware issue with old airport chips, so I pulled off mine... AND ALL USB FINALLY WORKED!!! I post here for other people having same issue :)

[@adgaming8772]

i have a 2006 macbook pro with mac os x lion on it i can pretty much surf do all . but i at least want to get el cap on it its 2,2 firmware is there any way i can upgrade it it has 3 gigs of ram stock , iv tired mavricks dosent work .... any idears all help would be greated

[@ekmead]

I have replaced both boot.efi files as you note in the video. I'm booting the Mac Pro from a firewire drive because it won't recognize USB sticks as bootable for some reason. I'm waiting for 16GB ram (on order) and could have my hands on an ATI Radeon HD 5780 tomorrow. Would these get rid of the blinking question mark? I'm at my whit's end.

[@alain026]

Someone please help me?! Everything went well, with upgraded videocard an such.... But after 10/13 mins el capitain freezes and reboots. What to do?! I have 5GB of memory and 2 Dual Core Xeon 3GHZ Processors, I monitored the cpu usage but nothing strange there.

[@TimurTripp2]

Have you managed to get this to install using only the Mac Pro and an already downloaded El Capitan installer app? I was able to install Mavericks without Target Disk Mode or hard drive swapping on my 2006 Mac Pro, by creating a bootable installer and making a few modifications to it. I haven't yet succeeded in doing this with El Capitan.

[@dosdude1]

+Timur Tripp I'm not sure, I tried placing the modified boot.efi file on the installer drive, but it still wouldn't boot.

[@TimurTripp2]

+dosdude1 Yeah, when I tried I couldn't get it to boot past the Apple logo with progress bar. I have just now installed over Target Disk Mode using a supported 27" 2010 iMac, and it seems to work just fine, in fact it runs faster than the iMac due to having an SSD while the iMac still has an HDD, LOL. I would probably upgrade the primary Mavericks install to El Capitan, but the Server version costs $20 and I have no need to use the newer version.

[@fixitwithdad8524]

Anyone done this on a Mac Mini 2,1? I was able to get it working except the keyboard and mouse (USB ) do not work at the login screen. Any ideas? thanks in advance

[@louisrosa9180]

Can't delete boot.efi even when holding option, could this be the reason why I only get a grey screen and it doesn't load el capitan?

[@TheMjRobots]

cool tutorial ...but i can't delete/replace the boot efi file from core services. Keeps saying item locked

[@brianmay3669]

Right click the boot.efi file, choose Get Info, when the box pops up, uncheck the box that says Locked. Now you should be able to delete and replace that boot.efi file.

[@mini_disc]

Right click boot.efi, click get info, then uncheck the locked option. also make sure you have permissions to modify in the bottom tab (I think it is called users and permissions but i cant remember!!)

It is NOT likely this is possible, I would recommend borrowing a supported mac from a friend, If that is not possible, maybe you can get lucky on a for parts listing on ebay.

Hi...macbook mid 2007 it's also supported for this guide or only macbook pro? thanks

[@dosdude1]

This only works on the Mac Pro.

[@PetNatividad]

Thanks for the very easy and clear instructions. This worked for me until I applied the update from April 2018. Now my MacPro 1,1 is on a reboot loop. It does the boot-up ding, apple logo, the progress bar, flashes a black screen, then reboots again. Any tips?

[@mci2727]

Hi dosdude1, I just followed your instructions (thank you for this) and installed El Cap on my Evo 860 SSD and reinstalled the drive in my Mac Pro 1,1 (2x 2.66ghz, 15GB ram, Radeon 5870) and El Capitan boots but it take a long time (like 5 minutes) and then it's glitchy having varying issues like the mouse won't connect some times and it won't fully load (past the background) some times. My GPU is a PC flashed one currently. Do you have any idea of the cause or what I should try to fix it? Yours didn't stay booting super slow did it? Thanks!

[@stevearkwright]

See if your video card is on the "metal" supported cards list - it sounds like you have no graphics hardware acceleration.

[@mci2727]

@@stevearkwright Where would I find that info? Is it a list for Mac Pro 1.1's or a list for El Cap?

[@heberferreira5418]

i have a MacBook Mid 2007 (2,1) with Mavericks Installed (via SFOTT method) could I use your App on my unsupported Mac to Upgrade to El Capitan? i have the El capitan installer .app on my App folder

[@rafaelcasero6237]

great idea, my Mac Mini 2,1 is showing just an folder with a ? on it when i boot it... Any reason why ?

Either a bad hard drive or there's simply no OS on it.

Hi Dosdude. i have an issue with SIP. on a mac pro 2.1. i need to disable it. (linux Elementary/ZorinOS install reports NVRAM error during install) and as SIP was introduced in el capitan, there is no way to disable it on my piker alfa el capitan (no recovery partition. as always i resort to OCLP or YOU for my hardcore mac stuff. :) been using your solutions for years...care to help me out?

[@wolfgangem1565]

I saw this video a few months ago, and I was kind of annoyed and thinking, "nobody ever has these! I will probably never even see one in person." Then guess what. Today I got one. It has OS X tiger on it though, so I'll need to do some work on it. Great videos btw. You should get a tripod.

[@dosdude1]

I know I need to get a tripod, but it's kinda difficult to use one, since I use an iPhone to record my videos. I do have a solution that I'll try at some point though. Kinda cool your machine still has Tiger, I ran Tiger on this one once just for fun, and it was extremely fast. Unfortunately, though, this machine has been replaced... By a new 2010 MacPro 5,1! I'll miss it, but I think the MacPro 5,1 will be MUCH better.

how well does el captian run if you have nvidia 8800 gt graphics thats alL i can afford for now as I have several of them and i did sub back and thanks for the reply.

[@BerendsJaap]

I installed el capitan on a external usb drive. Then i changed the boot efi and put the drive in my macpro1,1 but no succes... Any idea how to do this with a macbook pro retina as i can't put the drive in my computer....

[@dosdude1]

Just install El Capitan to a hard drive connected with a SATA to USB adapter. Then modify the necessary boot.efi files, and it should boot.

[@X5abeerX]

I can't believe that we are now being forced to hackintosh a Mac to make it work.

[@Deadhog_Rage]

i think i seen this same comment on the sierra video

[@nathantaylor2026]

This is in no way hackintoshing, rather just patching. When this was released, clover would have been what you used for hackintoshing. If this was done using actual hackintoshing software of the time, you’d nearly certainly brick it. Clover has a tendency to kill nvram, so would not have gone well.

[@danharvey-lowes3104]

I followed the tutorial using a MacBook Pro to update a Mac Pro 2,1 with Target disk mode, but when the Mac Pro's SSD was put back after being modified, a folder with a ? flashes at boot up. What did I do wrong?

[@fixitwithdad8524]

make sure you replaced the EFI file in both places. I had the old one in the first location and it did the same thing. Hope this helps

[@dotinsideacircle]

Can I install OS X El Capitan on a white Macbook late 2006? A long time ago I installed 10.9 Mavericks on it. All is ok but the audio is a bit weird and Safari glitches. I'll probably need a graphics card like your video says? But these MacBooks have an integrated GPU so it's not possible right?

[@Scotthcolston]

Great tutorial... i ran into the wrong video card issue... I have the list of officially compatible cards as 1. nvidia geforce GT 2. ati radeon x1900 XT 3. nvidia quardo fx 4500 4. nvidia geforce 8800 gt. i know the first two wont work with el capitan, what about the last two? or should i purchase the radeon hd 5770?

[@paullangton-rogers2390]

One curious thing... Like the guy who made the video I have an old Mac Pro 1,1 2006 tower unit (high spec, 8-core CPU 32GB RAM, 5 HDD's in it about 6TB).. the guy who sold it me clearly patched the bootloader with the 32-bit boot.efi as it came running Yosemite. Interesting it had all the drives working in it and one of them had El Capitan on (the seller told me ran both MacOS versions because of some music app only supported on El Capitan). He would change the boot disk using the 'Target Disk' feature in MacOS. It's interesting how he managed to have it booting with drives in every bay but yours only seems to boot with one drive in. I have noticed my Mac Pro since it hasn't been able to run MacOS for a while until I saw your video due to disk failure seems to have the same problem, it will not boot ANY OS off a hard disk while there's multiple disks in. It will however boot Linux or Windows from a USB bootloader TO a specific hard disk drive! Mac's seem to be very restrictive on the EFI firmware and how they boot and what they'll boot! Older Mac's and new Mac's which even have the security chip to check MacOS supported versions! Built-in redundancy by Apple to get folks buying newer machines I guess..bit cheeky really given the price of Mac hardware and fact old Mac's are often future-proof and can run for decades with plenty of upgrade options.

[@crobygaming]

Hello , I try to do that with an IMac 2006 and it’s booting, go on the session but the keyboard and mouse it’s not working. Do you ave a solution for this ? Tanks .

[@bxershrts]

Amazing video! I got it all to work on many drives and a few macpro 1,1 - my only question is how to flash the firmware to 2,1 before the elcapitan install - as the firmware will NOT work or update after elcapitan is installed on the 1,1 - so it must have to be done "before". But as I think of this, the drive is formatted before installation....so my question to you is -how? and when is the firmware flashed before the elcapitan install? Thanks!

[@dosdude1]

It should flash just fine within El Capitan. Are you using the Mac Pro 2006-2007 firmware tool for flashing?

[@bxershrts]

Thanks for your reply - I "JUST" found out just this very second that the flashing is NOT done to the drive but to perhaps the logic board somewhere! I thought the flash had to be done to the hard drive! I put in a Lion OS drive and flashed the firmware update and have been trying to copy it over..but it was totally unnecessary ...as I just put my el cap drive in and it shows 2,1 ..ALL GOOD!!!!! Thanks!

Hello, what's up? I'm trying to install El Capitan on a unibody MacBook from the end of 2009. From an iMac 22 "from mid-2014 with High Sierra. I take out the MacBook hard drive and insert it into a dock (sata - Usb 3.0) I boot the iMac from the El Capitan boot usb and install it on the hard drive of the laptop connected to the dock. Once the installation is complete, it restarts and the iMac starts from this unit with El Capitan and everything works correctly. So I reboot, I start from the internal hard disk of the iMac with saw and I put the files that you indicate in the tutorial in the corresponding sites. With the hard drive already on the MacBook I turn on and I get the signal that indicates that the system is not compatible. What can I do to get El Capitan on my MacBook?

Also would like to know if only is needed to put "boot.efi" from Piker-Alpha into ".JABootFiles" (hidden folder) of the USB drive by drag & drop, or it should be done in some other way. And want to know which is the role of a "another Mac that supports El Capitan" you mentioned in the text. There are some other step I'm not doing? Thank you!

[@dosdude1]

+Julio Ferraresi You can't boot the El Capitan installer drive on the Mac Pro, that's the point when you need a supported Mac.

Thanks for the vid. great job. but why do you need to create a bootable drive? you can directly instal it on the target drive using the OSX app and then take it over to your mac pro and apply the patch. can't you?

[@dosdude1]

I guess you could, the USB drive is more reliable.

[@daveaultman]

Nicely done. Followed your video instructions to get an old backup clone of a 10.8.5 laptop's HDD to boot on my Mac Pro 1,1 (2,1 flashed). Worked flawlessly. Crashed the system when I messed around with the App Store and the upgrade to El Capitan stuff. I'm actually leaving towards running Linux (Ubuntu-Mate) as primary OS on this machine. Only issue there is getting a 64-bit install disk to run. 32-bit installed and runs great.

[@dosdude1]

I have another video on my channel detailing the El Capitan installation process.

Can I take the Piker-Alpha Boot EFI file and use it with the M. Lion drive I created earlier - would that work at all? Thanks

[@dosdude1]

+adamjg4 You'll have to use the version for 10.8 and 10.9. I wouldn't recommend using MLPostFactor though.

[@adamjg4]

+dosdude1 ...But Mac PostFactor is OK?

[@dosdude1]

adamjg4 No, you shouldn't use either of those. Use SFOTT.

Hi - I got El Capitan installed on the drive, and I can boot fine from a supported mac. When I put the El Capitan drive in my Mac Pro 1,1, it boots fine, but within a couple of minutes, it shuts down and restarts. Then it just keeps doing this. Any thoughts?

[@dosdude1]

+Mark Miller That's really strange, not exactly sure what could be causing that. Maybe try installing it on a different drive?

[@joachim595]

Can I do this on an early 2008 white MacBook?

[@darrylchapman4068]

The instruction was easy to follow and worked well. I used an ssd for the boot drive and added memory to improve performance. The Apple released a "security update 2018-001 10.11.6" that stopped El Cap from booting. Reinstalling the "boot.efi" file didn't work to recover. I had to make a new El Cap boot drive. Is there any way to apply the security update?

[@dosdude1]

Nope, that update is known to make the custom boot.efi stop working. I'd recommend hiding the update, so you don't install it again.

I'm having a tough time ... have followed your instructions but when i hold option dawn and boot never get tone or screen to come back up... just black screen. Does graphics card need to be in certain slot?

[@dosdude1]

You can't use the Option menu if you don't get a boot screen/are using an unflashed PC graphics card.

I'm installing El Capitan on a MBP 6,2 I used diskmaker 6 to create the USB installer when I go install it on the unsupported MBP it call home and tells me this software can not be installed on this computer. Where did I go wrong? Any help will be appreciated.

[@dosdude1]

This method is for a Mac Pro only. You cannot run El Capitan on an unsupported MacBook Pro.

[@deongholston3047]

dosdude1 gratefull for your stuff.... i have mac pro 2 tower and have a sad that i loaded up per your instructions... i get a chime on start but never anything to the display... the little blu light on display never flashes blue like it supposed to... the video card is a nvidia quadro fx 380.... any ideas

[@ShandraNick]

Will it work with Macbook 2006 (2,1)??

[@garciadevin1997]

And when you use a 5000 series, can you use airplay to an apple tv for instance? It uses the native driver?

[@dosdude1]

No, I don't believe you can use AirPlay on any Mac Pro, as AirPlay requires a CPU with Intel HD Graphics.

[@techbp759]

You save my life!!!! I followed your video and it works like a charm :)

Hey no audio is on my mac after the install why?

[@dosdude1]

Check your audio settings.

[@braedenhull4946]

[@alexmforero]

Many may Thanks, this was a very clear guide, updated to el Capitan my Mac pro from 2006 - 2,1, i needed to use zoom and ameba rogue loopback to do some routing with the audio, this guide was a life saver. It was unusable with Lion OSX. like to have a big paperweight at my living room.
