Ventura 13.5 logon with non Apple mouse/keyboard not working

Booting with Shift depressed initially and quickly gets to the normal logon. At that stage the problem as described above remains present. Once password entered the Mac boots in safe mode - takes a while - and I get another logon screen. At that screen all Bluetooth keyboards and Mice work just fine... Entering the password again get to a desktop where all Bluetooth devices continue to work. So, booting in Safe mode does bypass the issue.

So, how do I identify the issue?

Thanks :-)

Thanks.

A - using which Keyboard and Mouse. Apple KB and Mouse OR Third Party ?

It was using the Apple Magic Keyboard connected via USB just to make sure Shift would be detected

A - There are times when the Kernel Extensions do not load fast enough or at all until the Operating System is completely Loaded

A - This can sometime even happen with the Apple KB and Mouse unless they are cabled to computer

Yes, but it used to work :-( before 13.5. I've also left it for several minutes at the logon prompt and the Logitech and Keychron devices still don't work.

It's annoying but I can live with it :-(. Maybe another update or Sonoma will fix it in the future...

Thanks

OK. So I used Cmd + R and chose to Reinstall MacOS just now. When the reinstall was complete (abt 40mins) I tried again. I can report there is NO change to the symptoms. :-(. But as all the apps, data and configuration is intact I'm not sure how deep the MacOS reinstall was. i.e. IF the issue is a configuration one, it may not have changed the problem files. Or maybe this is just a MacOS 13.5 'feature'!

Thanks. The problem has the 'feeling' of support for third party devices not being enabled until a user is authenticated. Once authenticated drivers are loaded / enabled and all is good. Just speculation on my part...

If I can find another Bluetooth keyboard/mouse that isn't Apple I'll try those. As the issue impacts both the Logitech and Keychron devices I suspect it will impact other devices too.

If I make progress I'll update the thread.

Thanks again.

No third-party software installed or necessary for either the Logitech mouse or Keychron keyboard.

I've spent way too much time trying to sort this today. I'll live with it for now and maybe not power-down the Mac! Just Lock-Screen. If I get really annoyed I'll probably just reinstall MacOS! Hopefully that would fix it!

Thanks again.

@Dialabrain, no I haven't and probably won't now as I don't feel the issue is related to those devices directly. It's a more general Bluetooth/configuration issue. The issue is now slightly worse than previous; not even the Apple Magic Keyboard works unless it's connected using USB at logon time. Interestingly, the Magic Mouse continues to be just fine tho.

I did upgrade my M2 MBP to 13.5 and that works just as it should with the Keychron keyboard and Logitech mouse at logon. My conclusion is that the issue is most likely a problem with the config of the iMac exacerbated with the install of 13.5. It's going to be a non-issue in the next few weeks as the iMac is getting replaced with a Studio after which it'll receive a fresh install of MacOS. I'm pretty confident that will eliminate the issue.

Thanks to you and P. Phillips for your help. Much appreciated :-).

I'm going to cease further investigations.
