Thanks, Martin! I downloaded a Java package for macOS aarch64 from Adoptium and installed it. Opening BaseX.jar doesn’t seem to work, but running basexgui opens the GUI.

I noticed that the Start Up page of the BaseX documentation recommends that Windows users should download from Adoptium, but I ignored that since I’m on Mac. It seems strange that updating Java from java.com only gave me version 8, apparently.

Suggestion to those who maintain the documentation: Perhaps the BaseX documentation should recommend Adoptium for Mac as well as Windows.

Thanks, Greg

I updated Java to the latest version, according to the download page at java.com and according to the Update tab in the Java control panel in System Preferences. Running java -version returns this:

However, I am still getting the same error when running basexgui. Is there a trick or workaround for this?

You need Java 11 for BaseX 10, I think. I would think it should be somehow available on maxOS 12 but I don't do much on a Mac.

Dear Greg,

Suggestion to those who maintain the documentation: Perhaps the BaseX documentation should recommend Adoptium for Mac as well as Windows.

Thanks for the suggestion. I’ve added notes on macOS and java.com in our documentation [1]. In addition, our download page mentions Homebrew, which is a popular package manager, and which installs a proper version of Java automatically while installing BaseX [2,3].

All the best, Christian
