Max 5 crashes on startup w/ malloc error

    Sep 19 2012 | 9:56 pm
    Hi there,
    I'm having a funny problem with Max all of a sudden. It hangs every time I launch it. It shows a spinning wheel mouse cursor and it's totally unresponsive until I "force quit". It doesn't display any error messages, but the following shows up in my console log:
    >12-09-19 5:38:46.344 PM [0x0-0x4c04c].com.cycling74.MaxMSP: MaxMSP(978,0xad1632c0) malloc: *** error for object 0x4fa1000: pointer being freed was not allocated >12-09-19 5:38:46.344 PM [0x0-0x4c04c].com.cycling74.MaxMSP: *** set a breakpoint in malloc_error_break to debug
    I've tried deleting ~/Library/Preferences/Max 5 Preferences/. I've also tried reinstalling Max. No dice.
    I'm on a mac, running os 10.7.4.
    Does anyone have any idea what's going on and how to fix it?
    Many thanks,

      That error is unrelated to your non-startup.
      Perhaps your MIDI or audio drivers are not starting correctly? Try moving them out of the midi driver and ad folders in your Cycling '74 folder

      Thanks for the response. Hm... so I've emptied ad/ and mididrivers/. Now I get an error saying that there's "no mididriver folder or default driver" AND it hangs. :s
      Hrmph. Any others ideas?

      ok, put that stuff back then.
      Send in all your details to support@ and we'll try and figure out what might have changed on your computer.

      Ok, done. Thanks again for your help.

      The helpful people @support showed me the way. It turns out that I just needed to manually delete the /Applications/Max5/ folder before reinstalling. Now everything's working perfectly. :)
