Unable to delete broken login items

Same here. Spotify and Slack don't work for me, and I assume it's because of this (or I guess Spotify just doesn't work and results in these unknown items?). Look how bad this is. The "-" doesn't even work, and the checkbox doesn't even check on the item I am clicking. It checks some other "unknown item".

The funny thing is I just moved from Windows. Finally invested on a MacBook 2016, annnnd yep. Pass me some directories and/or terminal commands. Anything. I don't even have Time Machine set up. I just got this and I've only heard of that after this issue.

I have opened up a bug with Apple about this.

If you're able to, please comment on the bug report that you also have this issue!

It's currently breaking a lot of other apps:

I suppose they were generated by Spotify, which doesn't work for High Sierra, at least for me.

It seems unlikely Spotify is the culprit. I have it installed on four Macs running High Sierra and one, it works fine, and two, it's not creating login items.

The current Spotify version 1.0.63.617.g5aca9a2a

Another thing is, a friend of mine updated his late 2013 MacBook Pro, and High Seirra and both Spotify and Slack works. He doesn't have the issue aforementioned. I too had Spotify working for a while post-High Seirra update. And then it just decided to stop working. Slack's crash reports mentioned something about login items, which is how I got pointed here.

This is almost certainly a bug in High Sierra that is also causing applications to crash on launch. It appears to happen in the part of the applications' code that deals with the "Start at Login" setting. The system LSSharedFileListItemResolve call returns a null URL even though it also returns a status code indicating success. The applications' code appears to assume it would be non-null and passes it as the first parameter CFEqual, which leads to a crash. This appears to have worked reliably from 10.6-10.12 but something has definitely changed in 10.13 which may be affecting System Preferences as well.

No help, but... Can't remove 'unknown login items'?

Is there a reason you suspect Spotify is the cause?

Thanks for the update. Did you restore to Sierra or High Sierra?

Yea, I'm having the same problem too. It's probably a bug in High Sierra for which I hope someone in APPLE can respond.

Thanks
