Many users experience poor system performance with this app and try to uninstall it nearly impossible due to scattering across the OS.

Guest, hello!

Thank you for your feedback! I am Vicky, a Community Manager from MacKeeper.

Yes, we had problems with users' poor system performance and uninstall of MacKeeper in the past. But since 2018 MacKeeper has worked tirelessly to improve all of the issues our customers were facing. We proved that MacKeeper is safe and shows great performance by receiving top industry certifications: Apple Notarization, AppEsteem Certification and AV-test certification. All of these prove that whenever you’re using the app, you can be confident that the app you use is acknowledged to be safe, and so is your data. It’s an official confirmation of the app’s legitimacy, which matches the highest industry quality standards.

As for the uninstall issue — we fixed this problem a while ago. Any MK user can uninstall MK by simply moving it into ‘trash’.

Moreover, MacKeeper can uninstall itself safely if the user decides so Smile Without leaving any files in the system. To do so you can go to MacKeeper's Smart Uninstaller => choose 'Applications' where MacKeeper allows to safely uninstall any app that user wants => and choose to remove MacKeeper.

I hope you try MacKeeper once again and see for yourself how great of a product we are now Smile

My knowledge regarding computers, viruses, security, etc. is quite basic, all technicians were not only patient with my questions but also explained every step of the process in terms of which I could understand. The entire process actually took the technician less time than I was told to expect. I have already recommended this product/service to family members. Thanks!
