Logs and msl doctor

Logs#

MSL's logs are in ~/Library/Logs/MSL. Open Logs on the Tools tab opens the folder.

• mslhd.log — the background service: every start, stop, power event and error, with the details behind the short messages in the app.
• Mac apps started from the Dock or Spotlight write their problems here too, since they have no terminal.

msl doctor#

In Terminal:

msl doctor

It checks for things no other command shows, and lists each with ✓, a warning or a problem:

• Whether MSL's command-line tools are installed.
• Whether the background service is reachable.
• Every instance, and whether its distro is downloaded.
• Leftover files from removed instances, and cached app lists for them.
• Mac apps still pointing at removed instances.
• How much space the disk images take in total.

It only reports. If it finds leftovers, it lists them and tells you to run:

msl doctor --fix

which deletes exactly what it listed — nothing else.
