Has apple announced a timeframe of when the macbooks will ship with only native software for M1 chip? Currently software goes through a translation process in order for it to work on the m1 chips.
The new M1 Macs already ship with only native software. MacOS Big Sur is made up of "Universal Binaries" that contain both Intel and Apple Silicon (AS) code. On an M1 Mac, the AS code is executed. On an Intel Mac, the Intel code is executed.
(In fact, the Apple Silicon code is included on Intel Macs running Big Sur.)
Plenty of third-party software is already available as Universal Binaries. Intel code is only translated when no AS code is available. And you have to download the Rosetta2 translation layer to implement it.
If you're asking when will Apple remove the translation layer, so that only AS code can run (as it did by removing Rosetta from OS X Lion): nobody knows. Or if they do, they're not telling.
