What is a good COMPLETELY free mac hard drive cleaning software?
Hi! I am curious because I have an iMac that is running os x Yosemite, and it has 28GB left on a 1.11TB (terabyte) hard drive.It is just over a year old, and has a fusion drive (like a hybrid drive only better). I have looked all over to find a cleaning software that is COMPLETELY free. notice I emphasize the COMPLETELY part! Can anyone help? Thanks in advance!
