iMac 2014 only runs on mojave
Has anyone had this problem? I’ve got an iMac mid 2014 and it only runs on mojave. I’ve just picked it up from a computer shop to try and sort the software issue out. My Mac was with the IT guy for 3 days, he really struggled with it. At first it wouldn’t have anything but the maverick but today he managed to get mojave back on it. He told me not to update it to the big sur as it was just unresponsive. He very nearly gave up on it. Today I’ve tried to get Microsoft word installed on it but Mojave is too old for the newest version of word. I just need a computer for light work such as emails, saving files, word etc but I’m just not having much luck. All this from just trying to upgrade it to big sur which it popped up in my settings that the update was available. I have an iPhone and have done for as long as I can remember and never had an issue with it. It’s just this bloody iMac I’m not having much luck with :( thanks in advance guys.
