On Macs with Intel processors, you need to install the x64 version of Java; on Macs with Arm 64 (M1) processors, you need to install the Arm 64 (AArch64) version of Java.
There may be multiple versions of Java on your
computer, but you can specify which one to use when you
install Jim. Drag the downloaded Java install file to your
Desktop, then open a terminal window (use Finder to search
for "terminal" if you are not sure how to do this) and type the following commands:
This will install Java 17 to
cd /Library/Java/JavaVirtualMachines
sudo tar xvf ~/Desktop/*jdk-17*.tar.gz
/Library/Java/JavaVirtualMachines.
sudo /Library/Java/JavaVirtualMachines/jdk-17*.jdk/Contents/Home/bin/java -jar ~/Desktop/jim-9-installer.jar
This will launch the installer, and install Jim in
/Applications/Xinapse/Jim9.

license file, then you can get Jim to print out more detailed
