Sierra 16B2657 Conundrum
So we are getting more than a couple emails regarding the mismatch between 10.12.1 update from Apple showing build "16B2657" and Nvidia providing a driver that matches to "16B2555".
I can confirm that the mod listed below will work. Just change the "OS required" string to match to "16" and it works fine. (You will need to disable CSR)
MacVidCards still going strong
Working on new stuff, and can report EFI running on some new cards soon.
Orders still shipping, all good here.
