Wireless with 802.11r, 802.11k and 802.1x

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.


I found the answer for anyone who is interested.

According to this thread, no support for 802.11r/k for Os X up to 10.9:
