I have used Mac's off and on for years, my first one was a G4 iBook, and that was after Apple went to intel processors because windows vista made me so irritated and gave me fits, I had a 2011 MacBook Pro 15 inch with the dreaded graphics issue and ended up using windows laptops until the beginning of January this year when I found my current MacBook Air which is an early 2015 11 inch model, i5, 4 gb of ram and the 128gb ssd.... my MacBook Air runs circles around my 2019 Dell laptop i7, 16gb of ram running windows 10 pro. Enough for the plug for Apple, we all know Apple is far superior than windows, that being said, I have never ran any form of antivirus on my Mac's, and being forced to work from home currently because of covid, won't say my thoughts on that, not relative to the discussion, my company thinks I am using my windows computer because they demand anti virus software which I will never install on any of my Apple products, MY COMPUTER, MY CHOICE, but I use my MacBook Air for work all day without any anti virus, because it is enjoyable to use and I am not going to add something to reduce the awesome performance of it when IT IS NOT NEEDED AT ALL. I do use ad block pro in safari, but safari is the only browser I use on any of my Apple devices. Worst that happens is my company finds out and I get terminated, that's fine it is only employment. I have never had any issues with any malware on any of my Apple devices, and enjoy constant performance and stability of the system, without question.
