On Windows you can develop an app Plug a Android phone into PC/laptop Then debug or build and deploy apk directly to the phone, it helps with testing. But can you do this on a mac? Use GMS mac version, develop the app/code Plug in iphone via usb Then press debug/build to test app on iphone? If yes what is needed? Mac / Macbook GMS Mac Licence? If you have say bought the Mobile licence for windows version would that work on mac? Another thing to actually use the mobile licence (that includes android and ios) do you need to buy anything else or just install the free GMS version and enter the licence key for the mobile export?
