how can i activate mackeeper?

Do NOT install/activate MacKeeper. All it does is create problems.

Re: how to uninstall MacKeeper

MacKeeper is malware, there is a class-action lawsuit against the maker. Do not activate it.

Hey Monica,

You can activate it by logging into the app from its main page. Open MacKeeper, there must be a System Status page on the upper left. On that page, click Log In and log into the software with your email and password. This should work just fine.

Before you think of following the advice from tedfromaurora, please read this:

Mackeeper is the EBOLA of so called cleaning/performance applications.

Ciao.
