Hi Promise team. I can't find any qualifying documentation about compatibility for the old SANLink1 4Gb Fibre Channel Thunderbolt HBAs other than qualification for 10.8.1 and up. I have a client with several using Mac Pro's 2013 on 10.12 with StorNext 5.4.x. However, they need to upgrade to 10.13. Just want to make sure all is well there before we commit to the upgrade path.
