That folk only bring me the failures. Now if you were able to do a complete disk backup so you could go back to before what these apps do, sure, you can try again as most folk seem to disregard the advice from everyone I know which is "nope, don't even install it."
As to speed I find the most common reason is the Apple is using a HDD. We move the machine to SSD and the owner seems happy.
Hu CNET friends! I noticed my old Macbook has slowed down considerable the last few months or so. It's reached the point where it's hard to do my graphical design work.
Hence I spent an afternoon and came about something called CleanMyMac. The company claims it can remove junk and make an old laptop like new again. However, I read some mixed reviews online and some even says it's not safe to use. Someone has any experience using this software?
