The title says it all - it's been 24 hours since I setup my Mac Pro and ACD and I have honestly had more system freezes and issues than I did with 12 months of running Windows XP. Firstly, the system became unresponsive during a transfer of large files - the files stopped transferring and whilst one could open certain applications, the finder menus and apple icon were unresponsive (so I couldn't shut down etc) A while later I think it may be a good idea to run the apple system update and check if my OSX is indeed up-to-date - seems simple enough and the apple update box appears the same as it does on my windows machine for itunes and qt - however this one hangs 1/8th of the way through - stuck on "checking for software updates" 15 mins and no progress - internet is on firefox works, guess I won't be updating today then.. The third problem occurred 2 hours later when trying to install CS3 - it freezes whilst installing shared components and doesn't get any further than this - I worried I was being impatient but having left it installing for 12 hours overnight it's no further. That brings me right to the fourth problem, I eject my portable HD - which won't eject because "it's being used" and also can't eject the CS3 CD as that is apparently "being used" - unfortunately the app has been closed and isn't in fact "being used" So if we can't do that we must restart the system - fine, click on the apple icon select restart and bang - it's been 20 minuets and all I see is a blue screen - yes a blue screen, famous in windows although I haven't seen one in 2 years after 24 hours on a Mac I see one and it won't go away. It's just sitting there looking at me. Great start - I am losing money already by not being able to work.
