It arrived a couple days ago. Need to set it up and migrate the old files to it. Probably tonight but there is always something else to do. I don't know about Windows, but Mac Time Machine saved on an external drive works well.
I can delay it a bit because (oddly annoyingly) the current one has stopped auto-restarting randomly and is not overheating after an hour. It's like it knew it was being replaced... Of course I don't give sentience to a machine, but it is acting as if it did. Well, maybe some of the efforts I taken the past month are actually working.
Still can't get the current one to leave comments on blogs with any regularity, though, so that is enough of a reason to set up the new one. It's not like I don't try every few days, but constant failure gets discouraging.
I may be avoiding setting up the new one for fear of discovering it doesn't solve the problem. If it doesn't, I will just scream! And there is the thought that, if I don't open the box, it is returnable for 3 weeks. I mention that because this "newest version (2020) has a dedicated Mac M1 chip and may require more app changes.
But if I want to continue with Mac, I probably have to. A former co-worker just told me her office is going to Google software which (apparently) resides totally on The Cloud. I don't trust Off-site file storage. The security is probably better than on my desktop, but I am a WAY lesser target. And if someone wants to see my photos, they are welcome to. I keep no financial information or passwords on it.
