MacBook Pro Late 2011 owners, beware, Intel HD3000 have problems with Mail.app — you will see just a 100% black area instead of email content for some messages. You need to open email in a separate window, then it will show correctly. Not appears on discrete graphics. I already filed a bug with http://bugreport.apple.com. If you have this machine, please file a bug too, to get a faster fix.
