Same problem as Mangosteen1, I'm glad he posted this because I thought I was the only one having this issue:

When I try and open the .jar file on mac, a java program starts and shows up on my dock, but nothing happens. I've tried to unzip it and can't find anything relating to any of the instructions on here. I have all the java stuff and have hit a wall. Please please please someone help me out with this, I just want to get it running on my mac. I've tried the app version posted on here as well and that doesn't work either.

Have used xmage on mac since 2016, haven't had an issue since i downloaded Macs Big Sur OS.

Hello,
I have exactly same problem as blueXmage and Mangosteen1. Is there any update regarding installation xmage on Macs Big Sur OS?

Hey I need some help,I always get stucked on this,i tried waiting for an hour and nothing,can someone help?:)

When I extract the ZIP file, a files folder is created and not a java executable program. How can I solve this?

I once played xmage often. Now i like to restart.
Cant find a launcer and advice to rejoin. Please help me!
Where to go to and what to do? Thx!
Or is no one playing on this platform anymore?
Greetings
