Apr 23, 2008  Hi, I downloaded a 4 Gb torrent, after downlaoding i applied a patch from Maxxuss site.--Patches for Mac OS X x86 10.4.3 (8F1099). Now i get a kernal panic with ACPI, i have tried all said on this forum like platform=X86PC etc Please take a look at the photo. Unable to find driver for this platform “ACPI ” MACOSX version: not yet set. Ask Question 6. Macbook Air Panic on Boot, “Unable to find driver for this platform: ”MacBookAir7,2 ' Hot Network Questions The use of footnotes to translate foreign words in a novel.

Cursive fonts in word for mac. I've owned this computer for over 3 years with 0 issues, and just recently received: panic(cpu 0 caller 0x563ebd): 'Unable to find driver for this platform: 'ACPI '. N'@/SourceCache/xnu/xnu-1504.15.3/iokit/Kernel/IOPlatformExpert.cpp:1387 The computer will not boot, gives me the startup tone, then the apple, then this stack trace and error message on a gray screen.

I reformatted the drive, did a clean install of Snow Leopard (without the original install disk, as I didn't have one handy at the time). The computer worked rock solid for about a week then gave me the exact same error message. It seems to me like a hardware issue, and I have noticed the headphone jack acting up here and there, cutting out when plugged in, removing volume control until fiddled with. But unless something is electrically shorting out, it shouldn't cause anything of this nature right? I did remove an EFI program called rEFIt recently, though I did so on 2 machines running the same backup image and the other one (early 2011 mbp) has no issues at all so far.

(fingers crossed) Does anyone have an insight as to what this specific error message indicates? Thanks in advance!

The first time I received the error, it was on the backup image (which was once set up with boot camp and windows xp). I then gave it a clean install of Snow Leopard from the install dvd, only to receive the error again a week later. There was no partitioning on the drive, just a plain 10.6.8 install, on which I loaded 3 or 4 of my digital audio workstations. I wasn't relying too heavily on it because I was afraid of exactly this. I opened it up, cleaned out the fans, removed the optical drive that had been broken for months anyway, used the factory Penryn restore disks to return it to out-of-the-box condition (OSX 10.5.2 I believe), then flashed pram and smc. I just updated to 10.6.8 last night, but I'm not sure if the issue is dormant and waiting for another failure to pop up next time I'm performing live.

Try starting up from the recovery partition (by holding command-R), in single user mode (by holding command-S), in safe mode (by holding shift), or in Internet recovery mode (by holding option-command-R). If you already have backups and you can start up from the recovery partition or in Internet recovery mode, try choosing the option. It downloads an OS X installer and installs it over the current installation, keeping user files and settings in place. If you can start up from the recovery partition but reinstalling OS X does not work, try to. If you don't have backups but you can start up from the recovery partition, you can.
