MacBook Pro won't update properly
Hello there I recently recieved a preowned but perfectly functioning MacBook Pro which had been tested by my younger brother and given to me as the (slightly) inferior between the two (MBP's) he had to choose from.
However when I recieved it his name was all over everything and so I chose to do a DVD re-install for Mac OS X, which is where the problem first arose.
Firstly I'll give you the specs of my machine.
It's:
'Mac OS X
Version 10.6.8
Processor: 2.26 Ghz Intel Core 2 Duo
Memory: 8 GB 1067 Mhz DDR3'
That's obviously the basic info but I can provide more if needed.
Anyway after the re-install, and some difficulty logging in, I got on the machine and found that all of the dashboard applications were faded with a white circle cross through them. When clicking on them, the message states: "You can't use this version of the application 'X' with this version of Mac OS X" with no option to update. I have pressed the Software Update option on the Apple icon menu numerous times but it seems to find no available updates. The only thing that will work is iTunes.
The App store will not allow me to download Mavericks but to be honest I'm not sure if I should because yesterday I updated the machine and found myself locked out of the computer; it brought me to the login screen, I would correctly enter my password and it looks as if it is logging in, and then it kicks me right back to the login screen again, in an endless loop, which was eventually fixed with yet another DVD re-install.
As I've said I've updated as much as the machine will allow and I cannot access Safari now because it gives me a different 'Problem Report'.
"Safari cannot be opened because of a problem.
Check with the developer to make sure Safari works with this version of Mac OS X. You may need to reinstall the application. Be sure to install any available updates for the application and Mac OS X."
I would appreciate your help or hints to try and get this machine running. I can tell it's a great machine, there's just something I'm missing.
