Troubleshooting on macOS

Your save folder is ~/Library/Application Support/FasterThanLight. Library is hidden in Finder, so press Cmd + Shift + G and paste the path to get there.

Coming from the old wrapper?

The wrapper kept saves somewhere else entirely, under its own drive_c. If your progress looks missing after switching to the installer, see migrating your saves rather than treating it as corruption.

macOS blocked the app

Open System Settings → Privacy & Security, scroll to the bottom, and click Open Anyway. On older macOS versions, right-click the app and choose Open.

The game will not start after a manual install

You almost certainly skipped the signing step. Run it again:

codesign -f -s - --timestamp=none --all-architectures --deep /path/to/FTL.app

Launch the app directly

Starting FTL through Steam bypasses the patched app bundle. Open FTL.app yourself.

My game complains about -opengl

Stop passing the -opengl flag. It was removed in Hyperspace 1.5.0 and is no longer needed.

My game crashes before loading Multiverse

Make sure you are on the latest Hyperspace. The Multiverse installer is frequently behind, and this is by far the most common cause.

If you are on a laptop with both integrated and dedicated graphics, try forcing FTL onto one or the other. Otherwise your save file is probably corrupt, see below.

My game hangs while loading but I can hear music

Your save file is corrupt.

Resolving a corrupt save file

1. Find your save folder and locate hs_mv_prof.sav and hs_mv_version.sav.

2. Delete hs_mv_version.sav.

3. Move hs_mv_prof.sav somewhere else. Do not delete it.

4. Launch the game, let it reach the main menu, then quit.

5. Move your original hs_mv_prof.sav back, replacing the one the game just made.

Still stuck? Ask in the Hyperspace channels on the Multiverse Discord.
