Darth Geekonius Posted August 27, 2014 Share Posted August 27, 2014 I recently purchased a cheap Mac Pro 2.1 on Craigslist. I thought (wrong) that since this machine was originally a 1.1 with the 8 core upgrade and running Mavericks 10.9.4, that Yosemite wouldn't be a problem. I was wrong...anyone know how to get Yosemite to install on this machine? I'm about to go crazy! Link to comment Share on other sites More sharing options...

Darth Geekonius Posted August 29, 2014 Author Share Posted August 29, 2014 Is it a hackintosh or a real Mac? real Mac. It's a 1.1 that was updated to a 2.1. Currently running 10.9.4 Link to comment Share on other sites More sharing options...
Onixs Posted August 29, 2014 Share Posted August 29, 2014 it should if its currently on 10.9.4 Link to comment Share on other sites More sharing options...
Darth Geekonius Posted August 29, 2014 Author Share Posted August 29, 2014 it should if its currently on 10.9.4 That's what I thought. But I can't download through App Store (developer program) nor manual from app after downloading from developer.apple.com I think it has something to do with the EFI or something. 32 vs 64 bit. But I don't know for sure, how previous owner installed Mavericks...... Link to comment Share on other sites More sharing options...

But I don't know for sure, how previous owner installed Mavericks...... Yosemite is probably 64 bit EFI and the former owner found a way to get around the original 32bit EFI setup that your machine normally would use. What you would have to do is find out if they used a bootloader like Chameleon or Clover. Most likely that bootloader worked with Mavericks and you need the newest version in order to work with Yosemite. Do you have an Extra folder at the root level of the bootable hard disk? If so, that means they used Chameleon. The only way to see if they used Clover would be to mount the EFI partition on your startup drive and see if its there. Or possibly a Clover install lo somewhere on the drive. This thread is asking the same questions. http://forums.macrumors.com/showthread.php?t=1740775 1 Link to comment Share on other sites More sharing options...
Darth Geekonius Posted August 29, 2014 Author Share Posted August 29, 2014 I'm just going to wait and see if they update the EFI thing for Yosemite. Don't want to put Chameleon or Clover on the Mac Pro unless it's a last resort. Link to comment Share on other sites More sharing options...
kyndder Posted August 29, 2014 Share Posted August 29, 2014 Probably they used this method to install Mavericks > http://forums.macrumors.com/showthread.php?p=18741613 There are many successful reports using this method, but, I don't know if will work for Yosemite...

MacUser2525 Posted August 30, 2014 Share Posted August 30, 2014 I'm just going to wait and see if they update the EFI thing for Yosemite. Don't want to put Chameleon or Clover on the Mac Pro unless it's a last resort. It will never happen Apple will not update the firmware they have had many years to do it for all the other hardware besides yours they have abandoned with that firmware issue. So your choice to get it done will only be Chameleon or Clover. Link to comment Share on other sites More sharing options...

Don't want to put Chameleon or Clover on the Mac Pro unless it's a last resort. What Im saying is that one of those 2 methods was probably already used. Do you have an Extra folder right below your Applications folder on your startup drive? Link to comment Share on other sites More sharing options...
kyndder Posted August 31, 2014 Share Posted August 31, 2014 Do you guys looked at "all" files linked to the post that I've sent the link above? Specifically THIS? The guy who created that method are using "workarounds" commonly used at Hackintoshes. like modified boot.efi, PlatformSupport.plist, InstallableMachines.plist, OSInstall.mpkg, SMBIOSEFI.kext and even VoodooHDA.kext...

Donw35 Posted September 3, 2014 Share Posted September 3, 2014 I have the same machine running mavericks as you do, I suggest you wait it out for the official release and keep weather eye on that thread, the same method used to get mavericks working will probably be updated for this machine. 1 Link to comment Share on other sites More sharing options...
