Why You Should Avoid MacKeeper
Thank you for this, their ads keep popping up, although I haven't been tempted to buy it, I have wondered about it's usefulness.
That fine example of the art of programming completely incapacitated my mother's iMac; we needed to completely reinstall the OS to fix it. Highly recommended for Mac users who are also devotees of Leopold von Sacher-Masoch.
MacKeeper sponsored CES for 5 years and was just at CES and is now doing remote tech support. People may dislike their ads but honestly they are a real company and I have talked with them at both events. Forgive me if I do not agree with self proclaimed experts
They prey on novice Mac users with their crapware.
"Real" companies run by crooks are nothing new so you can't use that to defend these sleaze balls.
I removed Mackeeper and my computer works much better.
