How to restore scheduled wake-up and custom login screen after macOS Tahoe update?

Hi everyone,


I recently updated my iMac to macOS Tahoe, and ever since the upgrade, my system no longer wakes up at the scheduled time. I am aware this feature was removed for a reason I don't understand, since I've used it since 2003, and now even the Terminal option doesn't work!!! This is a feature I need to have restored, as I rely on it daily.


How can I schedule to start on its own again?


Also, another issue that arose with Tahoe is that I can no longer use my own photos for the login screen! How do I fix this and use my own photo for the login screen? In the previous version I was able to do that, and for some unexplained reason, this was also removed!


WHY is Apple removing the BASIC features we use daily??? What is the reasoning behind that? Who was bothered by these features? And why?


And on iPhone, the snooze no longer works. I woke up late all week after I did this stupid update. Please point me toward the link on how to downgrade back to the previous version.


TIA


Please advise.

The same feature that scheduled startup restart shut down and everything else still exists, it was not removed at any time. The GUI interface was removed, but as others have noted, you can replace that with third-party software if you can’t copy and paste a sentence into terminal.

If it is still not starting up at the time set, you are most likely suffering from another addition to the Tahoe installer which enables FileVault. With FileVault enabled, you will see a startup screen that cannot be changed and if you do not login shortly after it appears the Mac will shut back down because it has not decrypted the drive.

You can disable FileVault in the privacy and security system settings. That will enable you to set the lock screen picture and allow it to continue the startup process on a schedule.

I'm curious as to how you can set a Lock Screen image that is different than your Desktop Wallpaper?

I wouldn’t know as I’ve never tried. My comment was on the effects of enabling FileVault, and the fact that you can have a different desktop wallpaper lock screen than the FileVault login screen.

I’ve never spent enough time on either the lock screen or the FileVault login screen to really care what’s on either.

FWIW, you can use the free OnyX to schedule Start Up and Shutdown Times.

Correct. The Log In screen is now the same as the Desktop wallpaper. That can't be changed.

This is a user forum. No one here can answer "Why" Apple does something questions.

I've been using Apple computers since about 1982. So, I'm hardly new to the technology. I've never had reason to use this feature. But I certainly don't judge your desire to use it.


The reason we suspect that few people use the feature is that, despite the fact that Apple removed it, the complaints are limited. Apple has access to huge amounts of usage data. They know what features most people use and what ones they don't.

Most likely, the newest users, in the last two versions, do not know of it because they opened their eyes on an OS that is without it. The thing is, "just because" some users aren't using it, that doesn't mean it shouldn't exist. It's a line of code, ultimately, that doesn't bother anyone, and it doesn't reduce the OS's functionality; on the contrary, it improves it.


@Brian: I will provide feedback. Thanks for the link.

For what it's worth, there are over 100 million Mac users. If it was an issue "for a lot of users", there would no doubt be thousands, or hundreds, or at least dozens of posts lamenting it's demise since Ventura. That hasn't happened. I'm certain it wasn't arbitrarily removed by Apple.


In any case, feel free to send feedback.
