Can't open MailPit

[nickc]

Thanks for clarifying, @sccr410.

The port conflict sounds like you might have running services left over from previous Local launches. Mailpit failing to launch even after you’ve removed the old Mailpit files could be a versioning issue.

You can try this to fix both:

1. Quit Local.
2. Open Activity Monitor and quit any running nginx processes.
3. Take a backup of Local’s ~/Library/Application Support/Local/sites.json.
4. Update Local’s ~/Library/Application Support/Local/sites.json and make sure all Mailpit versions use 1.24.1 by finding and replacing any 1.12.1 values with 1.24.1, leaving this under each site:

"name": "mailpit",
"version": "1.24.1",

5. Save your sites.json changes.
6. Restart Local and try running your sites.
