After I upgraded to Mountain Lion my MBP (late 2008) started to boot extremely slow. Last time it took 2 hours 46 minutes to boot, now it's already booting for 40 minutes.
I've tried cmd+r (just after restart), which brings up recovery mode; I've tried to repair the drive (via Disc Utilities), but no errors were found; I've tried to fix permissions and etc. I even tried to reinstall (not clean one, just on top).
Any of you know cause/solution to this? (Except clean reinstall, since I really don't want to do it now.)
Also, if I must clean reinstall, is it possible to do it via recovery mode? Or I must have bootable usb/cd etc?
