Cool, 10.10 and 10.11 has the same hardware support so we could safely bump to 10.11 (4.7% market 
share)

10.12 (Sierra) is at 5.9% and has the same hardware support as the still supported 10.13 High 
Sierra (13.8%)

-> Bumping to 10.13 would cut off up to 7.9% of macOS users, requiring 2 year older iMacs, 1 year 
older MacBooks, 3 year older MBP, 2 year older MBA, 1 year older mac mini, 2 year older Mac Pro 
(~2010 hardware is required, so 10 year old)

If that is an important feature, then it would make sense to set the minimum OS as 10.14 Mojave 
that has Metal support as the hardware requirement (generally macs from 2012 or older)

That would cut off up to 27.6% of macOS users by statcounter - note that some of these have newer 
hardware and could upgrade (~2012 hardware required, so 8 year old)

It’s not the default, but there’s an option to send OS information to LO when checking for updates. 
Have anyone looked at that data?
