    Since a few days I'm experiencing multiple crashes. Some programs crash almost immediately after opening. For example, every time I open an image in Photoshop, it crashes.

    The error message is always the same:
    Exception Type: EXC_BAD_ACCESS (SIGSEGV)
    Exception Codes: KERN_INVALID_ADDRESS at 0x00000000f08b2b51
    Crashed Thread: 0 Dispatch queue: com.apple.main-thread

    Another problem: from time to time my MacBook logs out all users without any warning.


    I have a MacBook 5,1 with 2x 4GB RAM (which has worked fine for me for months). I tried to work with 4GB only (I tried both), but the same problem remains.


    Does anyone have an idea what it could be?

    Thanks!

    You might have bad RAM.

    Download and burn the ISO from here: http://www.memtest.org/

    Then boot your machine from the disk and let it run for at least several hours.
