#CAN I UPGRADE MY MAC TO YOSEMITE INSTALL#

My plan is to install Yosemite straight to the SSD and boot from it.Д¬an you pls. вЂ“ Samsung SSD 840 EVO 250GB 2.5-Inch SATA III вЂ“ Added a Apricorn Velocity Solo x-1 Card & Peter/Keith вЂ“ i have a macpro 1,1 to which i have made the following changes: It works flawlessly if you replace the standard graphics card (XT 1600 or GT 7300) with an ATI Radeon HD 4870 (like i did) or a 5870 etc.

If this were to happen, the system would no longer be natively bootable on a 2006/2007 Mac Pro until it had AppleвЂ™s stock boot.efi replaced with PikeвЂ™s boot.efi againвЂ¦вЂќ (see ) This would be unusual, but it has happened in a few previous OS X updates and is now expected to happen again in the 10.10.2 update.

While this method is preferred because itвЂ™s a native EFI boot, there is some risk is that installing future Yosemite updates could overwrite PikeвЂ™s EFI32 boot.efi if Apple were to update the stock EFI64 boot.efi. Those who want to manually build their own bootable USB flash drive installer can follow the guide to installing Yosemite using the Piker-Alpha boot.efi. This method, a fork of tiamoвЂ™s bootloader, uses a replacement native EFI32 boot.efi boot loader that thunks EFI64 calls from the 64-bit OS X kernel to the EFI32 firmwareвЂ¦ вЂњthat can be restored to a USB flash drive using Disk Utility ( ).

I managed to easily install Yosemite on my MacPro 1,1, by using Piker-AlphaвЂ™s pre-patched bootable Yosemite installer: I recommend doing this without reservation to your old Mac Pro. The approach worked well, took some time of course loading, and I have been running it for a couple of weeks without any problems. So when Yosemite came out in GM and after the smoke cleared, I used the most recent form of Piker-Alpha boot file, a thumb drive and Hennesie2000вЂ™s excellent guide, that Mr. Back then I used the method of removing all the HDs from the Mac Pro but one, targeted that drive from a compliant Mac Book Pro running Mavericks and arrived at Mavericks on the Mac Pro on that drive, returning the other drives as well once OS was proven. I had converted my Mac Pro 1,1 up to Mavericks and followed the updates to their conclusion at 10.9.4. Also MacBook Pro 17вЂќ: from 2007 running Yosemite legitimately. Mac Pro 1,1 ATI Radeon HD 5870 1028MB 16 GB 800 MHz RAM 4GB, running as 667MHz updated pair CPUs Intel X5365 four HDs two DVD-RW. I decided to try some cheaper RAM without the Apple approved heatsinks to bring the total system memory up to 26 GB. One other problem that I have which I believe is more likely to be related to some new RAM that IвЂ™ve installed is the fans spinning up much higher than usual on wake from sleep. IвЂ™ve also been experiencing random wakes from sleep (wake for ethernet access is not enabled) along with the SSD that I have installed on a card in a PCI slot being randomly ejected. IвЂ™ve resolved the graphic glitches for now by selecting вЂReduce transparencyвЂ™ in the Accessibility settings. Installed the 10.10.1 update with no apparent problems. IвЂ™m not sure if this is specific to Lightroom or a wider issue. I have experienced a few graphical glitches whilst using Lightroom 4. Not a huge issue, I may get around to calling customer support as prompted by the pop up window if I feel the need to see if it can be resolved.

The install itself went smoothly and early tests indicate that everything appears to be working with the exception of Facetime which was also broken for me under Mavericks. Secondly I used PikeвЂ™s new boot.efi, (thank you to commenter Ralph Sampson for pointing me in the right direction) as I believe TiamoвЂ™s existing version will not work. Firstly, instead of installing on to a newly formatted SSD I decided to try the upgrade route and install on to my existing drive thus preserving all of my installed applications. There were only two things that I did differently. Using almost the same method as outlined in that postВ I have a working installation of Yosemite. You can read all about the method I used to install Mavericks despite this limitation in this previous post:- Mac Pro 1,1 and Mavericks. As many of you will know the original 2006 Intel powered Mac Pro does not sport the required 64bit EFI to allow either Mavericks or Yosemite to install via the usual method. Having let the dust settle a little from the initial release of OS X Yosemite, I decided to take the plunge and see if I could coax it on to my Mac Pro 1,1.
