No one has answered this question:
I have therefore decided to leave it on from now on. As someone once said "things fail when you switch them off and on again" so it's going to stay on until the new computer arrives. The monitor's switched off when I'm not using it. I have also researched this - leaving a computer on 24/7 - on the internet and can't see a potential problem: it's in an unheated room, by a window, so there won't be an overheating problem. It doesn't run any scripts overnight. However, I'd like to hear if anyone else leaves their Mac on all the time, please?
I posted that on Sunday and it has not been switched off since then. Some days, like today, I do not need that Mac, so I don't even switch the monitor on.
Does anyone else here leave their Mac on 24/7? Thanks.
WRT the computers awaiting delivery, I'll let you know how I got on when they arrive.
