MacKeeper has a decent range of security features that protects your device in real-time. I’ve reviewed over 30 different antivirus programs, and I have pretty high standards when it comes to my Mac’s security. There are also some pretty decent identity theft protection features which I found to be particularly useful. There are many great tools that I can use to maximize the performance of my Mac and keep it running light and fast, even though it’s pretty low on hard drive space. In general, it’s a pretty decent program with a lot of great features. I was nervous about testing MacKeeper because of the company’s past history, but I’ve been pleasantly surprised by the software’s range of features - a significant improvement on previous versions.
