I managed to ship a bug affecting folks making 16bpc images on 10.11, and I idly wondered what the percentage of folks using Acorn on 10.11 were. The answer is a little above 2%. That surprised me and is lower than I thought it would be. Folks on 10.14 are a little above 75%, which also surprised me. Almost 20% for 10.13, and a little above 3% for 10.12.
