I used it on one of my MAC computer and I had major issues.
It deleted some of my system files. After calling them they
said it could not happen. WRONG
When I showed it to an apple tech he assured me that’s what
happened. Since they I stay away from any programs the make
special claims to cleaning any MAC computer. If does need
any adjusting see a apple professional. I’ve had computers for
over 27 years and with my experience. Apple computer can only
screw up if the operator does it.
