[QGIS-Developer] QGIS for Apple: Intel vs. arm

[Andreas Neumann]

Hi Peter,

Thanks for this feedback.

I remember when Apple switched from PowerPC to Intel that they had kind 
of compatibility/abstraction layer that allowed old software to work on 
the new intel platform. Are there similar plans with the switch to arm?
