Works Great and Yes Macs need some attention as well

All computers have hard drives.
Macs may have a different OS than a PC but there is still memory
loss. Although many will say Macs will run forever without doing anything, they are machines that have to be maintained and cleaned. This app works great at restoring memory. I use it first thing in the morning to restore memory before a busy day begins.
