My mac´s hard disk is getting bigger and slow besides I doubled from 4 to 8 gb the memory and from 250 to 1 tb of hard disk space. How do I free up space from the hard disk??? There is any mac application to use o a 3rd party one which I could use???
There are a number of free programs on the web (OmniDiskSweeper, Grand Perspective...) that will show you where your disk space has gone. find out what folders are filling up, and that will help you decide what to remove.
