Hi, Apologies in advance if i have posted this in the wrong area. i'm new to tech forums. I'm a bookkeeper! About a year ago I installed Parallels 14 on my imac in order to use Myob accounting software. Usually it takes a while to boot everything up but once its open i can run the accounting software fine. About a month or so ago it just stopped working. Parallels takes ages to open, as does Windows 10, then once open and i have the blue windows screen nothing works. i can't open any applications. I don't understand why it has all just stopped working and i don't know where to start to try to remedy the problem. I have a 2017 iMac 3GHz intel core 5 with upgraded Ram (non apple) 16gb. everything else on my computer works. Has anyone else had this issue ? I need a solution especially if we go into lockdown again. thanks Kristen
