You’re saying they can’t send emails or save files because they are behind on updates? I’ve never once encountered these issues and they frankly sound like problems that people have when they aren’t used to using computers. I don’t use Adobe and Microsoft on Mac much. Chrome is obviously a huge memory hog due to tab sandboxing but realistically you just need to shut down the browser and/or most of your tabs once in a while. Updating the OS (or even restarting) sounds like overkill when the same result is likely obtained from restarting the browser with no tabs open or switching to Safari which is more RAM efficient
