I learned recently that System Integrity Protection was introduced in El Capitan: https://support.apple.com/en-us/HT204899 So, I'm curious why this patch checks for Sierra. I thought maybe it could just be a bug, but also that maybe the ptrace changes were added in Sierra. Do you know? I don't have an older machine to try on. I think it would be good to document or fix this decision, depending on what's going on. Tom
