No GUI and no tray icon

[sammichaels]

When starting the app, there is no GUI and no tray icon on both my iMac and MacBook Pro. The widgets are responding and the app is in the process list, but nothing else. It was working in the task tray except for sustained 4% CPU at all times so I unchecked the two top activities options and restarted. When it came back, it was at just under 200% CPU. Killed the process and now this problem. I've deleted the preferences plist item and that did not fix it.

This is the debug output (after the last line it just repeats the shell commands):

✅ status item is visible

I am on Big Sur 11.0.1 and eul 1.4.3.

this is an issue. will take a look soon

To follow up, the iMac I was testing this on crashed overnight (no kernel panic log, no nothing...log just simply stopped and the machine was powered off in the morning) and was ignoring input after booting up. After I finally got it working, eul was visible in the task bar again. There was a message from Big Sur relating to the size of eul in the task bar, but I had accidentally dismissed it before I could get a screenshot or really read what it said.

I'm reaching here, but perhaps eul was somehow hanging on talking to malfunctioning SMC. I didn't explicitly reset the SMC (other than unplugging after a few tries), but the symptoms of the iMac mysteriously powering off with no traces of panics or errors and then not accepting input after bootup points to the controller being unhappy. Rebooting didn't help the eul problem, but unplugging the power may have done something SMC related and resolved the eul issue.

If you need any specific debugging or info I'd be glad to provide it, but I've been unable to replicate the problem after a cold boot.

thanks for your elaboration. from your text I guess it may have some issue with SMC/battery-related calls. would you mind to open ~/Library/Logs/DiagnosticReports/ and upload suspicious files here?

I've experienced something like this after os restart. There were no tray icon or app interface. I resolved the issue doing Preferences -> Displays -> Resolution -> Scaled -> toggle any resolution and then toggle it back. Tray icon appeared and I could open the app. Probably an issue with OS

P.S. switching virtual desktops also helps
