Apps may be slow to load or may crash on first boot. I should also add that Intego Antivirus is experiencing some problems on Big Sur as of Jan 19 2021. Granted, RAM is generally an easy and cheap upgrade (if the user's Mac will allow it), but the software side and incompatibilities are where they should look first. Those are the things to explore first, before advising the user to spend money on RAM. If the computer worked great before the Big Sur upgrade and is now slow, then it follows that there must be either (1) an extra burden on the system caused by the OS upgrade (which I do not see on my Macs upgraded to Big Sur), or (2) some incompatibility between the OP's installed third-party apps and Big Sur. No platform is so robust and secure that it is fully protected against security threats on its own.Īlso, your advice to upgrade past 16GB RAM is probably unnecessary for the OP, unless they are using heavily RAM-intensive apps, editing video or crunching massive amounts of data. The myth of macOS being secure and fully protected has been debunked over and over again. In fact, it has saved me from malware infection a few times. I have used Intego products for many years now, and while I find that they do cause a significant performance hit while doing full scheduled virus checks in the background (which can be disabled), the real-time virus check feature does not cause any performance issues for me and never has.
Removing an anti-virus app may seem to improve performance in some ways, but you will also be exposed to other security vulnerabilities such as malware that targets Macs. While anti-virus software can sometimes affect performance of a Mac to a certain degree, in particular while virus checks are being performed in the background, I would respectfully disagree with your statements that "Intego is an unnecessary antivirus app" and that "Macs do not need any antivirus protection."Ĭould you please back up your claims with real-world facts, such as benchmarks, statements from security experts that conclusively prove that Macs do not need antvirus protection and so on? Macs are NOT fully protected from viruses by default, any more than any other OS.
