Licensing to buy Davinci Studio via Appstore

Hello,

If I will buy the version 15 in App store. When version 16 will came will I have the update free?

Don't! The Appstore version is severely limited by Apple's sandboxing regulations.

Go for the full version. BM until now has never charged for upgrades, but who knows? Anyway, we paid one grand a few years ago and for what they have done since I would gladly pay another 300.

Agreed, there are limitations with the App Store version (I don't think you can use OFX plugins for example), and there are a few settings you need to tweak (the Resolve 15 manual describes those; just search for "App Store"). The only good reason I can think of to buy the App Store version is if your local distributor won't have Resolve 15 in stock for a while, or if the App Store version is cheaper (it's cheaper in my particular case, but cheapness comes at a price).
