I went out and bought a new internal hard disk and then restored the piker file to that drive with the same error. So I think Piker must not work with something on these machines.

Please try building the installer yourself. It is always possible that a few bits of data during the download of the installer dmg are getting corrupted and causing problems. Either use SFOTT or follow the guide in the first post. I have not encountered ANY of the errors that are being reported and have done the install dozens of times.

Have you tried booting in verbose mode so you can see where it is getting stuck?
 
Yes also for me. And thanks tons to 666sheep and Hennesie2000!!

The PikeYoseFix package by 666sheep and available at post #2166 downloaded and then opened and applied to my Startup drive running 10.10 (had been 10.10.1 before faulty update yesterday) then allowed a regular Apple App Store update to 10.10.2.

My set up is a MacPro 1,1; GPU ATI Radeon HD 5870 1024 MB; 2 x 3GHz Intel 5365 CPUs; 16GB RAM; two monitors, four internal HDs. It has been following this had from early on, starting with early Mavericks.
 
Pretty sure it’s the RAID causing this.

Is there any new information that would cause you to believe this? As I noted, the RAID has never previously been an issue, and has worked flawlessly for me through Mavericks, and right up to Yosemite 10.10.1.
 
10.10.2 Update

Hello!

I was humming away on my:

Model Name: Mac Pro
Model Identifier: MacPro2,1
Processor Name: Quad-Core Intel Xeon
Processor Speed: 2.66 GHz
Number of Processors: 2
Total Number of Cores: 8
L2 Cache (per Processor): 8 MB
Memory: 20 GB
Bus Speed: 1.33 GHz
Boot ROM Version: MP21.007F.B06
SMC Version (system): 1.7f10
Serial Number (system):
Hardware UUID: 00000000-0000-1000-8000-0017F20E5E32

With a SFOTT Yosemite install and an update to 10.10.1.

When I updated to 10.10.2, I got the black Apple® screen with a flashing file/? icon. I had to reinstall the OS X from my SFOTT key.

The question is; how do I upgrade to 10.10.2???

Will below work for me(others)??

There haven't been any updates for 10.10 yet but you can expect one of them in the future might. If you use Tobyg's script for Mavericks you can replace the boot.efi.tiamo that it puts in the /usr/standalone/i386 folder with this new one and change the name to boot.efi.tiamo and it will function just like the script did with Mavericks.

The steps would be to:
1. Install the script but DO NOT restart.
2. Delete the installed boot.efi.tiamo in the /usr/standalone/i386 folder
3. Duplicate the boot.efi file that is in that folder (command + D)
4. Change the name from "boot.efi copy" to boot.efi.Tiamo
5. Restart

Yes, that will work.
 
In my /usr/standalone/i386 folder, i only show a boot.efi. I have no boot.efi.tiamo to delete.



Could this be due to the fact that I have not downloaded the 10.10.2 update (again)??


You have to install the script first. There is a link to it in the post of mine (#1584) you quoted.
 
Im having the same issue as lurkingbf. I used the pikegrey efi installer. I'm on a 1,1 with a GTX 570. I installed 10.10.2 and i can't boot to that drive. Unfortunately i cant see my screen so I dont know whats really going on. I was able to boot into my bootcamp drive.

Were you running the NVIDIA web drivers? If so did you update them before installing 10.10.2?

I don't believe I ever installed them. I've just been running what OS X provides. I just reinstalled 10.10 so I'm back in OS X at least. If there is something I can check i'll be more than happy to help debug this.

I just had to reinstall from the key again. grr.

Just to be clear (sorry for being the dimwit!), you (one) runs the tobyg script: https://forums.macrumors.com/posts/18829695/

and then,

1. Install the script but DO NOT restart.
2. Delete the installed boot.efi.tiamo in the /usr/standalone/i386 folder
3. Duplicate the boot.efi file that is in that folder (command + D)
4. Change the name from "boot.efi copy" to boot.efi.Tiamo
5. Restart

Then, after this previously described procedure, you run the update to 10.10.2 from the Apple App Store??

And, this will solve the problem of 10.10.2 not installing correctly...??

I hope this helps other 10.10.2 sufferers!!

Thank you so much, Hennesie2000!!!

Yes that should be it.

Interesting we have the same configuration with 1,1 and GTX 570 video card.

There are NVIDIA web drivers? I also did not install any special video card drivers, and am just using what OS X provided.

I assume you are not also using an SSD RAID 0? I can at least rule that out, then.

Wonder what our next step might be? I was thinking to locate a spare hard drive and try from scratch to see if it was either the RAID, or some particular corruption specific to my installation. Appears not, though, as you're having the same issue.

Were you running the NVIDIA web drivers? If so did you update them before installing 10.10.2?

I found this page from the netkas site. Go right to the bottom and there is a link to a driver package that was uploaded yesterday. Might it beneficial to try these drivers and then try 10.10.2 once again?

http://forum.netkas.org/index.php?action=printpage;topic=8522.0
 
I had to install those drivers to get 10.10.2 to boot with my GTX 970

Worth a shot. Of course, I can't install the driver package that I linked. When I try, I get an error message that says I have the wrong OS X version, and I should please install 10.10.2 first. Haha...I guess I will have to go find the version for 10.10 first, and go from there.

Tomorrow...

Thanks.

You can use flat package editor to modify the distribution file to allow it to install.

Earlier drivers can be found on NVIDIAs website. Search using the GTX 680.

I did find an earlier driver for the 10.10 Yosemite I have installed currently. It installed and rebooted fine, but my dual monitor support was gone! Argh! Always something, isn't it?
 
Inadvertently Updated 10.10.2 on an Existing 10.10.1, now have boot issues

I had my Mac Pro 1,1 running Yosemite up to 10.10.1 with an upgraded ATI Radeon 280 card. I used the Pike boot.efi method mentioned in this forum.

Yesterday, I inadvertently clicked sw update for the recent 10.10.2. Now my system does not boot with display. I have a dual display set up with 4 drives.
Using my Macbook Pro and screen share I am able to see that my Mac Pro actually boots up with my old Mac OS X 10.7.5. Using this access I tried using the PikeYoseFix-gray.pkg and followed the instructions. Unfortunately no success in booting with Yosemite 10.10.2, it still boots 10.7.5 with no display.

Any suggestions would be appreciated.
