WasI was recommended to seek for assistance here fronfrom the Networking/Stack Exchange site towards OsXOS X queries, do hope someone has the answers.
Have El Capitan on a testing iMac and deploying 802.11r/k with FT-dot1x from a Cisco WLC showed no issues with wireless connectivity. Though one client showed up with a macbookMacBook with wireless issues. Turns out the OsXOS X version on the macMac is 10.7 "Lion"...that is apparently oldold and obviously doesn't support 802.11r/k. Found a good page within Mac support for IOSiOS (Wi-Fi network roaming with 802.11k, 802.11r, and 802.11v on iOS) but not a support matrix for OsXOS X.

Is there any available support matrix/table/information for listing which versions of OS X hardware and operating system versions towards 802.11r/k support?
