Re: Another major difference -
They broke video playback this time, that one is confirmed!
As of yet we do not know what else is broken.
Anyone using a Mac for work always needs to hold off for a few months at least, as so far every significant update - and many of the "minor" ones - has broken something important.
I am genuinely starting to think that there won't be any professional users of Macs in five years. Quite where new software will come from then is an open question.
