startup / shutdown issues

Troubleshooting, Questions


What I have found to consistently produce a clean and quick shutdown is to log out of the user account first. When that has completed I then shut down the machine and it completes the task quickly.
I'm going to try that! Thanks!
Except that it did not work this time. I did the user logout which went quickly. But shutdown just sat there...until I finally did a forced shutdown.

I'll have to dig a little deeper into this as time permits.

Indeed. It happened again today. I let it just sit there for 20 minutes. Only the backlight remained on, with the arrow pointer visible. And enough of the operating system continued to run that the screen turned off after 10 minutes, as I have it set to do.

If the problem has something to do with cache files, you could try clearing them. Use the terminal command: sudo purge.
 


Could someone please provide feedback on what I see happening all the time: laptop users choosing Shut Down, but then immediately closing the lid before the shut down process has completed.

In my opinion the user should exercise more patience and wait until the computer is actually powered off before closing the lid. I suspect an interrupted Shut Down is not particularly healthy for the software.

Please correct me if I'm mistaken and somehow the shut down actually proceeds with the lid closed. Looking to understand what happens in this situation.

If the lid is closed, the system now has an additional task (sleep). Depending on which task (sleep or shutdown) is closer to completion, that's the one that will take precedence (which is, I'm sure, what you would expect). I've seen a number of users open the lid of their Mac to wake it up and find that, as soon as it is "aware", it finishes the shutdown.

Certainly now that macOS takes forever and a day to shutdown, we'll see more of this.

This has become a bigger problem now that Apple has removed the power-on LED from Macs. You used to be able to wait for the light to go off before closing the lid. Now, the screen immediately goes black, and you have no clue when to stop waiting.
 



How about watching the keyboard light or using the caps lock key, which also has a light?
If all you're doing is putting it to sleep (and haven't initiated a shutdown), then you just might as well close the lid; it should sleep (although I've seen some instances when something else is running that prevents sleep and the user finds a very hot laptop in her bag... or, much later, one with a dead battery).
 


I have been noticing at reboot and re-login that macOS often forgets, for a half second, that the box for "Reopen windows when logging back in" was not checked. The last folder open will appear then disappear in sort of a lazy half-second.
Is it time to reset the PRAM?
 


I have a weird problem with my iMac 2019. Running 10.14.6 with latest security update. Whenever I try to restart my computer, it shuts down instead of restarting. It is consistent, not intermittent. It will restart when I install a system update but otherwise it won't. Has anybody else had this problem? I have done a search and I have found people with computers that won't shut down, but nothing where it shuts down instead of restarting. If anybody could point me to a resource I could use to troubleshoot it would be greatly appreciated.

Your milage will vary... After in-place upgrading from Sierra to Mojave, my mid-2012 MacBook Pro did not obey the Energy Saver sleep settings, and Mail kept ‘forgetting’ Gmail account credentials unless I quit and restarted Mail. PRAM reset did not cure it, but resetting SMC followed immediately by resetting PRAM did.
