Apple claims there are 20m registered developers on the App Store [1]. If each of them buys a Mac once every 4 years, that's 5m Macs per year. IDC estimates that Apple shipped 18m Macs in 2019 [2]. So 28% of all Macs would have gone to developers. If developers buy more expensive machines (or more machines) than the average customer, their share of sales could be significantly higher. However, I don't quite believe that there really are 20m active developers on the Apple platform. Evans Data estimates that there is a total of 27m developers worldwide [3]. It's not plausible that 74% of them should be writing software for Apple platforms. On the other hand, not all developers using a Mac are developing for the App Store. A lot of them will be Web developers. I wouldn't be surprised if developers' share of Mac sales is 30%. Maybe it's just 20%. I don't know, but it's definitely not tiny.
