Apparently, it's not working for Ventura smart groups yet - at least not with the beta installed?
I've got a test machine, with 13.0 beta 8, and none of the above descibed methods work... So it never turns up, no matter whether I use @awoodbury's solution (greater than or equal 13.0), or the regex one, etc. First I thought: maybe Jamf Pro interprets the beta versions as lower than the regular 13.0, but it should at least be shown when using "greater than 12.6"; doesn't seem to be the case though. Any ideas?
