Hello guys,


I have my MacBook Pro 13" for about 3 months now.I

But if I work with the MB or even surf in the net, sometimes the hole system is freezing and the colorball appears.

This lasts for about 20 sec or longer and than everythin is fine again.


After the last freeze I looked in the console and the last message was:

sandboxd: ([11223]) VTDecoderXPCServ(11223) deny mach-lookup com.apple.windowserver.active


Can somebody help me?





MacBook Pro, Mac OS X (10.7.3)
