Every time I reboot my Mac running macOS Sierra I lose my Launchpad layout. I’ve tried different apps, tried removing some preferences. All of the apps are reset to their default position.
Anyone have a solution on how to fix this?
I don't know what you've tried thus far but a solution I've found to work well in the past for Launchpad issues is just to force reset the Launchpad back to its default settings. Most people don't enjoy doing this because it requires you to then set everything back up the way you like it afterwards, but at this point that's what you're having to do after every restart anyways, so what have you got to lose?
To force reset Launchpad back to default settings:
I would then only move a couple things around in Launchpad for time's sake (in case this didn't work) and then restart your Mac to test!
If that did not work, simply force-resetting may have not be enough. Maybe it wasn't just the defined settings inside of the file that were corrupt, but the entire file itself. If this is the case, we need to delete/remove the file and trigger the OS to create a brand new one. You have two options for this!
