Note this is a demo program, but its one of the only demos that actually allows you to RUN the scripts. Another program you may consider purchasing is CleanMyMac.... does most of the same stuff but the demo doesnt allow you to actually clean the system.
So, onto the program we are talking about...
Fire it up, then click on the Maintain tab. There are a few check boxes here you can look into, but I went with these selections...
Click run...
Then click the Optimize tab...
Click run...
Then the Trash tab...
Click run...
I then did a reboot.
Most of these tasks can be done through Disk Utility, but I like these Utility apps that put it all into one place.
Anyway, let us know how it works out. Ive seen a lot of posts lately about similar issues.
