    Hi—first time posting... got myself into a very iffy situation....

    When opening Zbrush 4R4, I receive a "Scratch Disk Error" message:

    "Incorrect scratch disk path specified in 'ZBrushScratchDiskPath.txt'. The default 'Vmem' path will be used instead. " ...then... "Unable to read virtual memory file" .... then it crashes. this happens, in Terminal it reads:

    cpe-69-204-10-203:~ matthewheitanen$ /Applications/ZBrushOSX\ 4R4/ ; exit;
    ZBrushOSX(10222,0xa09d0540) malloc: *** mmap(size=16777216) failed (error code=12)
    *** error: can't allocate region
    *** set a breakpoint in malloc_error_break to debug

    I'm not familiar with Terminal at all, if it's even possible would I need to set a "symbolic breakpoint"— any ideas on what I should do, or what any of this means, would be much appreciated-peace and thank you- Matt H.

    Is this the latest version? By the way, always good to look in the Console app too, clear it out and reopen Zbrush and see what that says. Autodesk software has been iffy on Lion and Mountain Lion for me too.

    anyone googled error code 12 and got here, here's one possible solution. in my case with 4R6, it was due to case sensitive partition. the solution was create additional case insensitive partition and do the following.

    :create case insensitive partition and place zbrush app under it
    :symlink /Users -> /users
    :create tmp folder in case insensitive partition and symlink it to /
    :edit /Users/Share/ZBrushData/ZBrushScratchDiskPath.txt point a case insensitive tmp directory

    Chances are if you had case sensitive partition, the installer failed to create ZBrushData directory in the first place. I just copied over from working copy but if you symlink users first and install, it might work.
