When I reboot, my apps stick together on the first space, when before rebooting, they were on different spaces.

  • Are these "real" manually-created Spaces, or automatic fullscreen Spaces?

After moving your app's window to a space (or opening it on a space), right-click on the app's icon in the dock and select Options > (Assign to) This Desktop. This makes the app always open on that space, also after reboot.

  • I only have options keep in dock, open at login and show in finder. Commented Sep 8, 2021 at 6:39
  • Do you have multiple spaces open when you do that?

  • They open in their own spaces (fullscreen). Commented Sep 8, 2021 at 8:52

    Fullscreen Spaces are not "real" Spaces so you cannot tie any app to one like you can with 'proper' Spaces. tbh, I don't know how they should behave after reboot, as I never use them, because of the above.
