I solved this for another this past weekend. I send Greg Smith (again new system with OS 10.15 Catalina) the dmg file for Mac OS java 8 update 91 which always seems to work. Same issue arose about two years ago when Mac OS went to 10.13; vassal no longer worked on the newer java, Java is up to java 8 u251 now I think. Just because there is a new java, does not mean you have to use it. Same for Mac OS, Vassal Engine. Took me some effort to find the j8u91 installer again, I have it on a dropbox. I can make it available; [bill@wargameacademy.org](mailto:bill@wargameacademy.org). I also have instructions of how to NOT have your Mac update to any new java automatically, with risk of disabling vassal. ---

Yep. I’m afraid that Vassal 3.3.0. doesn’t launch at all with the latest versions of Mac OS Catalina and Java. Is there any solution in the works? ---

I am on the latest Mac OS Catalina and have not experienced a problem like this, nor on any version of MacOS going back the 3 years that I’ve been using Vassal. Happy to share any configuration details that I can, if it might help. ---

Vassal had always worked on my Macbook just fine. Ok. Inside VASSAL’s app bundle you should find /Contents/MacOS/VASSAL.sh. That’s what’s supposed to be run when you click on the app icon. What happens if you run that manually, from a terminal? – J. ---

How do I run it manually from a terminal? Never done it before, sorry.

It looks like everything you’ve run except for ‘which bash’ has failed to return. Does anyone who is more familiar with Macs than I am know what’s going wrong here? [Next page](https://forum.vassalengine.org/t/just-loaded-mac-os-catalina-have-a-problem/10654.md?page=2)
