Apple releases OS X 10.8.5 with fixes for several bugs


Good, that explains why my screen saver wouldn't start from to time, and prevent my MBP from locking itself automatically. Very glad it was just an annoying bug and that it got fixed.

They had an update in there for the drivers for my printer. Hoped it would cure the inability for it to always print with the desired settings and print with default settings at random regardless of the settings being set to the defined ones that I wanted.

Sadly I still have the same problem, costing me a fortune in ink compared to printing on my old windows PC's. Might be worth purchasing another make of printer and hopefully that will cure the problem.

I did the upgrade to 10.8.5 and now I can't watch any Youtube videos on my computer. Anyone know how to fix that little predicament? Thanks!
