I recently changed my OS settings to run in 64 bits. This has rendered vBox (v3.1.6 r59351) unstable and actually made the iMac reboot without any warning. Complete reboot. It is not like I was doing anything complex in Win XP SP3 or that I have tweaked the OSes (XP or Mac OS X). Reverted to 32 bits Max OS X mode. No problems at all. I was able to complete what I had to do (running QuickTax - no much fun - next year I'll use the online version). So, in short, latest vBox version crashed under OS X SL 64 bits mode but is quite fine if the OS boots in 32 bits. Max",defect,closed,host support,VirtualBox 3.1.6,duplicate,,,Windows,Mac OS X
