Resolved 2006/2007 Mac Pro (1,1/2,1) and OS X Yosemite

[mikeboss]

The only issue I have is an error reading PCI cards

usually a GPU without a proper EFI ROM gives an error when listing PCI cards in System Profiler.

----------

Is Yosemite on a Mac Pro 1,1 actually worth doing? Does it run well? Is it stable?

What are the pitfalls?

IMHO it's totally worth it, yes. why retire a machine that is perfectly capable of running the latest OS?

no pitfalls. the only issue known ATM is that it's not possible to boot the Recovery HD partition.

Yes can someone quickly tell us how it runs, as I'm backing up my stuff as we speak ready to go.

I am running the latest beta on my Mac Pro 1,1 and it runs great. It's fast and all my apps work just fine. I'm going to update it again when the new release comes out later today.

I've posted a "beta" of the SFOTT script for Yosemite here http://oemden.com/?p=1361

Please read before trying. as you'll have to go in settings to make the Yosemite choice available.

I've installed it many time on the MacMini2,1 so it should go for MacPro.

note : I've only tested with Yosemite GM. I believe it will be OK with today's Official Yosemite release that I'm waiting for being available on the French AppStore so I can test it and ok I'll update the "standard Sfott script".

Consider this as beta

EDIT : had a glitch with the .dmg - it is ok now.

It runs fantastic. There really aren't any issues.

Is there a place I can download Yosemite besides App Store which won't let me download it ?

Search google or torrent.

Thank you

I just want to say thank you to everyone who contributed to making this happen, you guys rock.
I can't wait to install it on mine,
Has anyone tried sfott beta yet?

 

[hadleydb]

I also want to thank everyone who made this happen. I've been following this thread for some time and it works great! These old machines still have some life left in them. You guys are awesome!

Search For Mavericks Download Enabler. It may not work anymore but that'd be the simpliest way.
Note do not use the kext version but the USB Stick version !
search here on MacRumors, it's Rastafabi member that made it. it soudl work for Yosemite too...

 

[phlevin]

Really great work! Can't thank everyone enough!

Mavericks has been flawless on our old MacPro 1,1 looking forward to Yosemite but i'll give it a few weeks just to let the dust settle. Haven't just jumped right in for an OS update since OS 7, guess I'm dating myself.

I have been using Yosemite since DP1 and switched to us as my main OS with DP5. It has been great. No KPs, only some minor graphical glitches.

I am backing up now and then will install using SFOTT. I have made the install media already and it seems like it will work good. Thank you oemden!

EDIT: I can confirm SFOTT beta worked great! Thanks again!

SOFTT worked well on the public release! Smooth and easy! I'll write a guide tomorrow. Any way to get iMessage working?

Any way to get iMessage working?

Would say: call the Apple Customer Support with the Code provided by the iMessage App - see here (#894 and on), also here.

Well...no luck so far!

I've tried twice
-building the USB drive from scratch, following the instructions to the letter (black boot)
-restarts apparently fine (haven't tried shutdown/cold start, only restart with option key)
-apple logo, status bar (slows towards the end for a few seconds)
-then I get the "could not be installed on this computer" message

boot.efi copied to coreservices and i386
kernel in System/Library/Kernels
board ID added to Distribution File, InstallableMachines.plist and PlatformSupport.plist

what am I doing wrong?

Current system:
10.9.4 on a 1,1/"apple" Radeon HD5770 using Tiamo's boot.efi


(Also tried SFOTT, first time I got an error, second time the autorun command wouldn't even start for some reason as it went back to the main menu automatically)

Just about to download myself. I was going to wait for a couple of weeks but I’m eager to use Dark Mode. There are loads of boot.efi files around, which would you say is best?

I installed Yosemite on a supported Mac mini and I have to admit I'm really not impressed with the dark mode. And since it only works for the menubar and the dock background, it's nothing special. It should be affecting at least all the Finder windows!

Now that’s a bit poor. I was hoping for a themed effect like you used to get with the ShapeShifter Haxies from days past. Can you pop us a screenshot at all?

Try these steps - I've successfully installed the Yosemite final release right now on my MBP2,2 (late 2006, EFI32).

 

[mikeboss]

just in case anyone wonders: OS X Server 4 can be installed and so far it seems to run just fine.

The dark mode looks somehow not bad on unsupported Macs without graphics acceleration. If you change the appearance (in System Preferences) to Graphite, dark menu bar & Dock as well as Highlight color Graphite too, then it looks quite decent and remembers a little bit at NeXTSTEP ....

and remembers a little bit at NeXTSTEP ....

nah, nothing compares to the NeXT GUI owning a bunch of NeXTcubes myself, I still am very much in love with the old 2-bit greyscale GUI. it so was not distracting from the content or work on the screen. BTW: the Dock needs to be placed vertically on the right border of the screen

Like it. A lot.

The boot EFI seems perfect for a normal boot, I’m going to try the recovery…….

I’d downloaded on a compatible Mac and installed to a USB hard drive partition of about 16GB which ensures a native system with a good recovery is present. I make a disk image from this which I copy to somewhere else.
Now I boot into Mavs and change the boot.efi and relevant plists and hey presto a working Yosemite. With Mavericks I also mounted the recovery and did the same replacement jobs. I can’t at present remember if I modified the basesystem.dmg that’s on it.

Still not working... Now I'm a little confused about this whole boot.efi thing.

Since I'm running with Tiamo's script my ioreg says "EFI64".


...I've replaced the boot.efi on the USB drive at both places. Did I need to do that at all?

(I still get the not to possible to install message)
