The Elder Scrolls Online v4.2.11 includes additional improvements for the Mac game client, in addition to fixing a UI issue where it appeared as though skills were not leveling up and the drop rate for the Silver Dawn Motif. If you having lag problems I feel bad for you son, I got 99 megabytes and this patch is one.
