Boot device selection showing options no longer available

[user1234]

Hello fellow Apple device users.

I have had an issue for some time that my 2018 iMac does not seem to refresh its booy device list.

There are 5 drives to select from when I boot holding down cmd, but only two are still valid and only those two show up in the startup disk setting inside of Mac OS. These are options I have previously had and booted from, but I have since deleted these APFS volumes (and a bootcamp partition).

I have tried to reset NVRAM and also SMC just because why not, but it is of no help. Is anyone else here experiencing this issue? Is there a command line tool to manually refresh the boot device list used at boot?

I’m running High Sierra 10.13.6, but this issue has existed at least since High Sierra 10.13.0

(Also, how annoying is it that the globe (keyboard and language selection button) switched placed with the ”.?123” button in iOS 12 Beta on the iPad? I’m accidentally switching all the time, i think 8 or so times during this post alone...)

Hmmm. Clearing NVRAM and SMC should've refreshed this. - So unless for some reason it's still seeing the devices even though they aren't there..... Have you checked your partition map isn't retaining them? Inside macOS, do they show up in System Preferences Boot-picker? Do you have them listed in a custom fstab file?

I actually prefer it this way. The bottom left is more accessible than the middle. You now have access to the numbers/symbols by dragging down on the normal keys, so you don't really ever need to go to that menu anymore, so might as well have languages more accessible

They do not show up in the System Preferences boot picker. I included this in my post but it may have been unclear. I don’t have a custom fstab. I don’t know why i still have 3 now non-existing partitions showing up...

That’s kinda the issue. I’m using the special characters button all the time to find the characters that aren’t available by dragging down, and I also change keyboards a lot (between the iOS keyboard and Gboard) so it’s in my muscle memory. Now they have switched places. I’m sure I’ll get used to it after a while.
