Yesterday my Mac crashed and after trying to turn it on again I recieved a message like this:

panic(cpu 0 caller 0xffffff800667b0b2): "VM page 0xffffff800ad5fad0 should not have an error\n"@SourceCache/xnu/xnu-2422.1.72/osfmk/vm/vm_kern.c:457 Debugger called: Backtrace(CPU 0), Frame : Return Address ... ... ... Can't perform kext scan: no kext sumaryczny BSD proces name corresponding to current thread: unknown

Kernel version: Darvin Kernel Version 13.0.0: thu sept 19 22:22:27 pdt 2013; root:xnu-2422.1.72~6/release_x86_64 Kernel UUID: ... Kernel slide: 0x0000000006400000 Kernel test base: 0xffffff8006600000

System uptime in nanoseconds: 0

And I know there is a similar post and a good answer to that.

I can't access Recovery HD. When I try to do it by hitting Cmd-R or Alt while booting, Mac freezes and does nothing except generating a lot of heat around CPU. I can only turn it on, do nothing and wait for the kernel message above.

What can I do?

I'd advise you to boot your Mac from the system DVD and check the internal disk. The coincidence of kext scan failing and the recovery HD unreachable let me diagnose a major disk (and not just filesystem) trouble. The CPU overheating might be a consequence of a fool's fsck.

If you don't have a system DVD to boot your Mac (which is the case since Lion), I advise you to ask a colleague who have the exact same MacOS X version to build you one.

  • Do you think that formatting hard drive and installing OSX from scratch can solve those problems? I'll try that. I've installed a new SSD drive maybe 2-3 months ago. I fear it can cause those problems. But it started after i installed OSX Maverics. It worked well with OSX Lion

  • I would first analyze the disk from another one. If you have Mavericks on a DVD or on an external HDD, start with this. BTW, when booted from an external disk, you might also check for any errors collected before the crash within /var/log/system.log. These error messages may help you target the real problem: hardware or software.
