Hello, I have had my mac for about a month. I am having numerous issues with it. - After it has been in stand by for awhile I sit at it, wake it up, and attempt to open safari from the dock. Safari bounces up and down but never opens. I force quite and try again...same thing. I restart my computer and it works fine (but it only restarts if i force quite safari first). It has since done this with system preferences and iTunes too. -time machine. I set up time machine to back up to my WD 500gig external. It worked great for like 20 days and now tells me everyday it cant back up. I open time machine but cant figure out what the issue is. - Date and Time. Often my time at the top right corner freezes on a time. I scroll over it and I get the spinning color wheel. Again, a restart fixes it. I called apple and a tech ran through some diagnostics and told me that she did not know what was wrong but thought it might be my logic board. She also said I might have to reinstall OSX to fix the issue. Wont I lose all my data if I uninstall my OSX? I ended up ending the call because I could not understand the lady. Anyone have any thoughts?
