So I have an iMac 2014. In download big sur and it faults. I’ve tried ctrl r and ctrl p&r and I have managed to almost download 3 times. Every time on the apple screen it stops for hours or overnight. It will not download and restart. I’m now stuck with the apple start screen. Computer bust! I know it’s old but how can apple get away with breaking people’s computers like this, it’s all over the internet so I’m not alone! What is the solution, buy a new one?!!
