Yes this is possible since earlier releases.
First configre your SSID with any security you want (Open, WPA-PSK, WPA-802.1X) and then add this piece of config for MAC filtering:
aaa attribute list <YOUR_LIST_HERE>
attribute type ssid <YOUR_SSID_HERE>
aaa authorization network <YOUR_LIST_HERE> local
wlan <YOUR_WLAN_PROFILE_WHERE_TO_FILTER_BY_MAC>
shut
mac-filtering <YOUR_LIST_HERE>
no shut
!
// now add the whitelisted MACs like standard usernames. Be advised this usernames cannot be added through GUI (at least before 17.3):
!
username 0021553f0672 mac aaa attribute list VOICENET-2-ALLOW
