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)

here's a really nice guide about how to create a USB installer ->

That's the one I used.

Do I still need to replace the USB drive's boot.efi if my ioreg reports "firmware-abi" = <"EFI64">?

just follow the guide step by step and it'll work. I did it myself over and over again (few hours ago with the Yosemite release) and it works flawless.

I know and that's the most frustrating part. I already tried to install 2 times last night and a third a few minutes ago with a freshly built USB drive. I have no idea what's going on, I'm following the guide to the letter.

sorry to hear that. in my experience, not every USB stick or external HDD works. have you tried using another thumbdrive or external disk to create the installer on? just last week I ran into this obstacle...

I'm using the same thumbdrive as the Mavericks install. I'm going to try another one...

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 ....

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 :)

Fixed ... ;)

When editing "Distribution" and PlatformSupport-plist, are you ABSOLUTELY sure you didn't use curly quotation marks such as “”〝〞? If you are ABSOLUTELY sure, make ABSOLUTELY sure AGAIN. More likely than not, that's the reason it isn't working for you. Some editors add such quotation marks by default, even if that isn't your intention. The quotation marks MUST be straight: ".

I don't add the machine IDs, I just replace existing ones (don't need the others anyway). this way, I never ran into troubles with quotation marks...

Thank you for this. Working perfect on my Mac Pro (1,1) now 2,1 with 5770, with an SSD and 2X 3Ghz. Extremely fast! Boot in 5 sec.

You're the best!!

IT WORKED!!! :D

Turns out that was the problem. I was absolutely sure but yes I made absolutely sure again. ;) Textedit added a curly quotation at the end by default for some reason. I indeed replaced the last one by straight quotation and....here I am posting this from Yosemite! :cool::cool::cool::cool:

"one more thing"... ;)

I found the Finder a bit slower than usual and checking my Activity Monitor, I see that kernel_task constantly takes about 40% of cpu...is this still part of the "optimization" after installation? It warned that it could take a while so I'm wondering...

[edit] looks like it's related to my Avid audio interface and not even related to Yosemite, let alone this particular discussion, so nevermind... I'm figuring it out...

Spotlight is probably indexing.

I installed Yosemite GM3 on MacPro 1.1 upgraded to 2.1 (dual Xeon X5355) and a AMD HD 5770 Flashed with bootscreen ok.

Yosemite works, but I have defective graphics and extreme lag.

What can I do? Thanks and sorry for my english.

Mac Pro 1,1 Yosemite

Hi I've currently got Mavericks on my Mac Pro 1,1, I installed it using my new iMac by connecting a SSD and using the iMac to do the install then copying over the boot.efi files or whatever they are called. Can I do the same for Yosemite if so why files do I have to replace etc?

You can do the same thing and you will need to replace the boot.efi files with the new ones for Yosemite.
