Thank you for your relpy Harv,
I've checked that location for an error log, but no log is there. Am I required to turn logging on somewhere in the game properties files? I read elsewhere on Linux troubleshooting that another player was advised to do so.
Steam is up to date, MacOS is up to date, Java is up to date, and Rising World is too.
It may be because I have to 'Force Quit' sometimes that there is no log being generated. Other times though, it crashes back to the desktop.
I know my graphics card only having 512mb may be an issue, I can run other games just fine though.
Thanks for your help.
