Hi all My 2009 13" MBP keeps logging out when I've left it unattended. It should just be sleeping, but when I come back it's logged me out completely. It's not low on battery or anything & this seems fairly recent behaviour. I believe it's resulted in corrupted external drives & all sorts, so I'm not happy about it Any way I can figure out what is causing the log out? (and stop it?) At this rate I'm going to have to reinstall the OS from scratch - I can't have it doing this Hoping somewhere here can help ..
