OS Vulnerability and 2014 iMac
My wife has a late 2014 27" iMac. She's running Big Sur 11.6.5. Everything she's read says she shouldn't upgrade to Monetary with a computer this old. However she's very concerned with this newly reported OS vulnerability and is wondering what she should do.
Can she safely upgrade to Monterey and know her computer will work well and not be too slow or is there an anti-virus anti-malware program she could run like Avast that will protect her.
