![]() This is an issue that myself and other users have reported. ![]() 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. I realize this thread is old but I was going to make my own thread to share this experience but figure its better to not make another thread on this subject and just add my opinion here.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. Although I have read some possible ways to remedy this, I have also read other reports of those who cannot fix the issue, and their MacBook becomes worthless. As I'm sure most of you know this update BRICKED (ruined) some of these models. I did not test other parts of the system or programs, there may have been other issues, but I wasn't going to put up with the App Store issue. Had to revert back to Catalina and leave my computer on for over a week to repopulate the people section of photos (I have 40,000 photos) amongst some other nonsense time consuming issues. ![]() I researched and tried the fixes I could find with no luck. The App Store would not load after the upgrade. I did so reluctantly after reading success from others, my system was fine and stable but I wanted some of the new features. I personally would not upgrade to Big Sur (again). I have a nearly new MacBook Pro (Retina, 15-inch, Late 2013 / 2.6 GHz Quad-Core Intel Core i7 / 16 GB 1600 MHz DDR3). I love Best Buy for helping me with every large purchase, from Computers and Dishwashers to Monitors (TVs) and Microwaves. I'm not sure about some rules here but when it comes to tech these days (and home appliances) I've been doing the Best Buy pay overtime plans. ![]() Summary, don't update to Big Sur unless Apple makes you and hopefully by then your finances will have settled. Their prevention was almost like seeing actor Wayne Knight in his Jurassic Park role on the computer screens waving his little finger at me. Apple even prevented me from using Safari. Ultimately it met its maker when I could no longer update individual pieces. I did everything I could to make sure I squeezed every drop of possible usage even installing the max Ram (which was not much.) My first big desktop Mac from that time period is still sitting on the floor of my middle bedroom. ![]() I have been using a Mac since about 2008 and I still consider myself a Mac Newbie. ![]()
