Securing macOS 10.13.6 High Sierra
Hi, guys,
I'm sticking to 10.13.6 on my 9.5-year-old 27" iMac, which is my workhorse as a graphic designer. For many reasons, I can't upgrade beyond that.
What I'd like to know is how well my iMac is secured, especially after reading the "Apple urges users to update devices due to serious security flaw" story on the "Today" online page today
I use 2 paid virus-protection programs, clamXAV and the basic Avast Security, as well as Malwarebytes.
Is there anything else that I should be doing, besides being careful not to open suspicious links or websites?
Thanks!
iMac 27″, macOS 10.13
