Installed 14.4b5 on iMac 18,1. Booted fine, then installed post-install root patches and WiFi is missing from the top menu as well as settings. Very odd - even in settings, when clicking on WiFi, options don't ever show.
I reverted back to previous root patches and I see the WiFi options again, but with an exclamation sign through the WiFi symbol in the top menu bar. This is to be expected, but I guess the post install root-patches have a problem with WiFi on this iMac 18,1 with 14.4b5.
So, I guess this means WiFi doesn't work with OCLP 1.3.0 in 14.4b for an iMac 18,1.
Just thought you'd like to know.
