I’m going crazy trying to figure out why my plugin is not appearing on some older mac systems. I have the following settings set in the jucer:

I’ve tried building on my personal m1 arm macbook as well as an older 2016 intel macbook and it still won’t appear on a couple users macs. I am not sure if it’s an OS issue because for one user they upgraded from 10.11 to Catalina and the plugin will still not show up. We even tried running “auval -a” and it’s not appearing in their list of plugins. I’ve tried building for 32bit/64 bit architecture but I guess this option is deprecated.

I’m a bit at a loss how to proceed, I’ve read various threads on this subject but it all seems like voodoo to me to actually figure out what the root cause is.

Any advice??
