Have you ever been browsing the web and you come across a site that tells you that you could make your Mac faster and clean it up, or that you HAVE to do these things? Never listen! This is a complete scam and includes the likes of MacKeeper, TuneUpMyMac, and MacBooster. Each of these apps claims to make your Mac faster but actually causes tons of problems. They not only can't do what they say, but are actively eating away at your available resources and slow the rest of the computer down.
Moral of the story: don't download an app because an online ad said your computer was slow. If your computer actually is slow, send us a message and JTec will let you know what your choices are before you spend any money.
