Mac MacOS Sequoia 15.5 Co-op LAN Multiplayer "Connection Failed" unsolvable issue

[iksudo]

I am trying to play with my girlfriend on LAN coop while on the same WiFi network, but we are getting "Connection Failed" issue all the time.

We are able to ping each other with no problem. I also tried using ZeroTier, and we can also ping each other using the IP Addresses from ZeroTier, but can't connect. We tried her hosting the server and me hosting the server, both ways.

Tried everything after carefully reading the multiplayer troubleshooting guide reinstalling the game, firewall setup is fine (also tried disabling it), restarting router, restarting our laptops, creating different farm settings, nothing helps.

System: MacOS Sequoia 15.5
Stardew Valley version: v1.6.15 build 24356

Hi, this is my first post here, but I actually managed to solve this issue so I'm spreading the joy here...

With a lot of troubleshooting help by Grok, I found a solution. The issue we got was the same - two macs in a house and mac1 can't join a game hosted by mac2. A PC can join no problem. So I spent the last two days and found the solution:
You can successfully join a game hosted by another mac by making a SCRIPT (using Script Editor) and typing in:

do shell script "/Applications/Stardew\\ Valley.app/Contents/MacOS/StardewValley"

And then, just save it as an App and give it a custom icon if you want.

DONE.

No more steps. That's it.
It works also by running via Terminal... but this one is more Apple-ish. :)

Enjoy farming!
