Panoply offers a few different install options for Mac.
There are some troubleshooting tips for mac on the download page as well:
On macOS: Panoply has been notarized in order to work with the heightened security settings of macOS 10.14.5 and later. However, it is possible that Panoply might fail to launch if your Java installation is not so notarized, in which case you may see an error window stating that Panoply requires that Java 9 be installed. If so, you might try installing a more recent Java, built after August 2019.
Some users who have a second display attached to their Mac have reported Panoply does not respond after they select an input file via the filechooser dialog. If you experience this, please download and try the version above labeled (JFC), which uses the Java filechooser.
There have been reports that Panoply for macOS fails to launch on recent Macs built with "M1 silicon" ARM chips. If this is the case for you, you should instead be able to use the "generic" PanoplyJ version and launch Panoply from the Terminal shell.
I use the recommendation to run the "generic" version from the terminal. To do that you would remove your current Panoply install and then download this version
Here are some rough instructions.
You unpack the tgz file (I think you just double-click on it, or something like that).
Open a terminal window. From spotlight search start typing terminal and it will come up, click enter and terminal will open.
Then we probably have to set the .sh file to be executable (we only need to do this once on install):
- From terminal, navigate to your extracted panoply folder for example: cd ~/Downloads/PanoplyJ
- type ls -l to see the files and their settings (there should be a readme, a jars folder, a panoply.sh file and a panoply_macos.sh file)
- type chmod +x panoply_macos.sh to make that file executable
Then try running panoply from the terminal by typing:
./panoply_macos.sh
