Best Security Software for iMac

NEVER EVER use any third party security, antivirus, cleaning or any other type of "maintenance" apps for Mac OS. The BEST security, antivirus, cleaning and overall all maintenance app for Mac OS is Mac OS itself. Simply keep it up-to-date and otherwise leave it alone and your iMac will remain secure and quick for years. Add third party security, antivirus, cleaning or any other types of "maintenance" apps and expect a slow Mac, unwanted errors and quirks and an apparently buggy system. It's really that simple.

1. No.

2. Unless you're careless about what you download or are concerned about Windows malware, everything you'd need is built into the OS.
