Question

Finder keeps popping up on iMac

The finder window keeps popping open on my iMac. [I have tried rebooting.] I opened console.app and the log window and found the following string. Parts of this keep repeating, so perhaps this could ID the problem. Can anyone tell me how to fix this? I'm not an IT person. Thank you very much.

Please reset the NVRAM and then restart in Safe Mode, instruction links are right below. If these resets do not help, then please post an EtreCheck report.

I tried the first two methods and it seems to have worked, so far for a whole day. Thank you very much!

The scripts I mentioned are still continuing on console.app, so I guess they were not related. Probably due to this being and old and clunky iMac.

Best, Allen

The NVRAM reset seems to have fixed the same problem on my old MacBook Pro too. Definitely one to keep in the bag of tricks. My bet is that once they get some age on them, problems like this only get more common, and I can probably squeeze a little more life out of this hardware with tips like this. Won't fix everything, but it's another thing to try when things go sideways. Thanks!
