Wireless with 802.11r, 802.11k and 802.1x I was recommended to seek for assistance here from the Networking/Stack Exchange site towards OS 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 MacBook with wireless issues. Turns out the OS X version on the Mac is 10.7 "Lion"...that is apparently old and obviously doesn't support 802.11r/k. Found a good page within Mac support for iOS (Wi-Fi network roaming with 802.11k, 802.11r, and 802.11v on iOS) but not a support matrix for OS 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?
As of 10.13.6 macOS doesn't support 802.11 v, k or r but interoperates with APs that have it enabled.

EDIT: No change (e.g. no support) in 10.14 Mojave.
EDIT 2: Still no support in 10.15.
