MAMP on macOS ventura 13.2 apple silicon M2 can't use port 80?

Question

I try to use MAMP (v6.7) with apache on port 80.

Error: The port 80 is already in use

The Mac is a fresh new install without anything installed on it, macOS 13.2 on M2 apple silicon .

If I try on other port like 8080 or 8888 it's ok, but I need port 80.

sudo lsof -P -n -iTCP -sTCP:LISTEN

I have tried the new "Indigo Stack" app with apache on port 80, exactly same error, the port 80 already in use.

How can I found what is listen on port 80?

Any idea? Many thanks in advance.

On my M1Pro MacBook Pro, MacOS 13.2 I'm having the same issue.

As a temporary workaround, I've been able to get MAMP running using port 80 by using the scripts in the MAMP directory:

Start : /Applications/MAMP/bin/start.sh (this is same as clicking Start in MAMP)

Stop : /Applications/MAMP/bin/stop.sh . (this is same as clicking Stop in MAMP)

There's a few other scrips in /Applications/MAMP/bin/ that might be useful to check out.

Side note, I'm following this reported issue https://bugs.mamp.info/view.php?id=9913 for an offical fix (had to sign up to view:/ but there's a few more reports of the same issue this week so it's not an isolated issue)
