Install

Open it the first time

1 Open mielwm-0.1.2.dmg and drag mielwm into Applications.

3 Go to System Settings > Privacy & Security, scroll down and click Open Anyway. Every release is signed with the same certificate, so macOS keeps your permissions when you update.
4 Allow Accessibility, so mielwm can move and focus windows and hear its shortcuts.

Release notes

Released November 2, 2026.

After waking from sleep, windows from other workspaces no longer move to the current one. Some apps rebuild their windows on wake, which mielwm took for new windows. Now a window that comes back goes back to its workspace and place.
Menu bars that show mielwm's workspaces no longer miss those windows for up to ten seconds after waking.
Settings has less space above the search field and above each pane, and more between the search field and the list.
