There is a need for reliable programming solutions that work well ARMs, before considering any ARM development for WaveLab. I mean, no time to loose. I prefer to wait until the transition is as easy as possible. Each year there are already some quirks with each new OSX version, hence I can be scared when the CPU change too!
Also, it remains to be seen, how performances will change compared to Intel. I am a bit skeptical (today at least), about any benefit for high-end machines. The ARM switch sounds more like a money strategy for Apple than a global technical advantage. In the same time, I wish to be wrong.
It seems so far that Apple declares non-compatible machines after about ~7 year (Mac Pro saga). Hence if you buy something today, think about it as an investment that won’t last more than 7 years.
For the time being, and until WaveLab 11 inclusive, no development time will be spent by me for ARM support.
