We had a huge upswell of Mac users not being able to connect and the newest OS was at fault. Older macs further away...no issues. Mac's with new OS right under an AP... couldnt connect reliably, huge CPU spikes and or crappy wifi.
Ahh, I love Apple. But yeah, in this instance, dont discount the OS.

Looking into the Zoom dashboard statistics of some of these calls we are seeing the "Max Loss" percentage go up to 99% frequently and back down to 2-6 % on wireless when there are no issues. We can generally co-relate this to higher ping responses. I would also love to what other Universities are doing to look at this. This thread reminded me of a recent on on the NANOG mailing list about Macs and wireless issues.

I can’t remember all of the details but the tl;dr summary that I remember involved some interaction between Bluetooth, possibly Location Services, and Wi-Fi. -- Julian Y.
