There have been many reported bugs and even blank gray screens that prevent access to the system, so if you install over your current OS, you're risking having to boot into recovery or reinstall from the ground up.

Now that the OS on the MBP's disk is new enough to support it, shut everything down (older Mac, then the MBP) and restart everything from its regular disk.For those of you who've already gotten Beta Preview or Developer Preview access to Mac OS X 10.10 Yosemite, I highly recommend installing it on a separate partition on your hard drive.

Then, restart the old Mac from the "external disk" (the MBP should still be in target mode at this point), and update to 10.6.8. Connect it (via FireWire) to an older Mac, start the older Mac from your retail 10.6 DVD, and have it install onto the "external disk" - the MBP. Otherwise, if you have another (older) Mac with FireWire, there's a trick you can use: start your computer with the T key held down, and it'll go into target disk mode, which essentially means it turns its brain off and acts as an external FireWire hard disk.
If you have the installer DVD that came with the computer, you can use that. It sounds like your retail disk has an older version, so it won't work on that Mac. Anything older, including the standard build of 10.6.3, won't have drivers/config info/etc for that model, and hence cannot boot it. The MBP model you have shipped with version 10.6.3 build 10D2094 - this is a special build of 10.6.3 with support for that model (and probably some others released at the same time) added. As an additional test, I booted other Macs with the install discs I have, they all worked fine.

Is there anything else I can do to get my MacBook Pro to boot from the install disc? Thank you very much! I installed Applejack to fix the problem and scan my computer again. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
The volume Macintosh HD was found corrupt and needs to be repaired.Įrror: This disk needs to be repaired. I also held the D button during boot to run the Apple Hardware Test, again it found no problems.įinally, I tried to reset the NVRAM with no success, and I used Disk Utility to verify the internal hard drive which produced the following message: Verifying volume “Macintosh HD” Next, I ran Micromat TechTool Deluxe that came with my AppleCard protection plan to check my hardware, all tests passed. I am see and choose to boot from the USB drive when I hold down Alt during startup, but again it hangs at the grey Apple logo. They all hang at the grey Apple logo.Īlso, just to see if it was a problem with my optical drive, I followed instructions to use Disk Utility to make a disc image of the install disc, and "restore" that image to an USB flash drive. To diagnose the problem, I tried other startup discs, including my retail Mac OS X 10.5 Leopard install disc. However, the boot still hangs at the grey Apple logo. To boot from the install disc, I also tried (1) holding down the Alt key during boot to choose the disc, and (2) using System Preferences to set the disc as the startup disc. After a few minutes, I can hear the disc SPIN DOWN, and the machine still sits at the Apple logo after more than 40 minutes. However, the computer hangs at that step, there was no grey spinning wheel and the installer never starts. The disc can be heard spinning up, and the grey Apple logo appears. I inserted the retail Mac OS X 10.6 install disc, and held the C button on my keyboard to boot the machine. I wanted to re-install my mid-2010 15-inch MacBook Pro (Intel Core i7 2.66 gHz 8 GB 1067 MHz DDR3 RAM) which is currently running Mac OS X 10.6.8.
