Good morning. I have a 2020 iMac. I hadn’t gone on it for a day and when I did last night it said it couldn’t do the time machine back up and that there was an error. I have a WD external hard drive that I formatted for the iMac. I updated Big Sur and Safari last night as it showed me I needed to. Could that be the reason the external hard drive is no longer doing the time machine backup? I will send some screenshots later of what I’m getting when I try and do the time machine back up. Just trying to start the conversation. Thank you!
