"Launch At Login" does not work when App bundle is located outside of /Applications directory

I ran the app (which works great btw!) from the ~/Downloads directory since safari extracted the zip by default, and later noticed some log spam repeating every few seconds:

Dec 10 09:34:36 kintsugi com.apple.xpc.launchd[1] (dev.vandijk.BrightnessSyncLauncher[59549]): Could not find and/or execute program specified by service: 107: Malformed bundle: dev.vandijk.BrightnessSyncLauncher

I disabled "Launch At Login" on a hunch, and the log messages stopped.

Re-enabled "Launch At Login" and moved the App to /Applications and the log messages did not reappear.

I did notice the App does not appear in System Preferences > Login Items, but also dont know if that has fallen out of style with macos apps 🤓

For reference, another app i use (mos) has a "launch at login" option inside it, and appears in syspref Login Items. ex: https://github.com/Caldis/Mos/blob/master/Mos/Utils/LaunchStarter.swift

Good catch. I think it's because the Downloads folder is protected these days so the launcher can't access it.

The API to add your app to System Preferences > Login Items has been deprecated for years now. I was also disappointed when I found out about this. The officially sanctioned way of creating a helper application seems obtuse and not transparent to the user and I never really liked it, but I decided to do it the officially supported way anyway.

I think you're right about the protected Downloads folder, it works fine if the app is in ~/

[OCJvanDijk]

Not really sure how to solve this actually, maybe I should just start distributing the app as one of those fancy DMGs where you can drag it into the Applications folder.

I've seen a number of apps detect when they are running from a path other than /Applications or ~/Applications and offer to move themselves into the main Applications folder.
