I have an early 2009 iMac. It was too slow, so I reinstalled the OS. After the installation it appeared to work fine. However it has a strange behaviour. If I try to open Safari it loads instantly, but if I press to update software button it gets blocked and I need to shut down from button. After that it does not even boot anymore.
As I thought it was a hard drive problem I installed a SSD. Now the system runs faster but it gets blocked if I press to update or system preferences for example. I think it can be a software problem, because some things work good and other not.
Perhaps it is because I am trying to install a very old OS. Snow Leopard 10.6.3.
Please any suggestions is highly appreciated and if anyone faces the same problems please share your solution.
Thanks a lot.
