Oh dear! Another great app going 10.11+ as the minimum platform requirement. Too bad! Our ecosystem is still largely 10.9 and 10.10, so I need app support for those OS versions. I can understand if you are moving to Swift development and need 10.10+ for the minimum, but to jump from a 10.8 or 10.9 minimum to 10.11+ minimum may do your target audience a disservice. I for one won't be able to upgrade (which i would gladly pay to do)!
