On a mac, Bonjour service is listening to all .local ending TLD. When using BrowserSync for example to develop a site, it’s working, but very slow, as the mac Bonjour service always waits for a timeout with each request.
I would suggest changing default Local by Flywheel domain to .test for example, as it’s a reserved TLD, see: https://tools.ietf.org/html/rfc2606
Other reserved TLD which will not be made global are:
- .test
- .example
- .invalid
- .localhost
