BIAB 2025 is an Intel app and requires Rosetta II on Apple Silicon.
next years OS release is not going to run on Intel macs.
That doesn't mean a thing. Apple has announced that Rosetta II will continue till 2027. This means that BIAB 2026 can still be released as an Intel app (I hope not but...).
If Apple does not change this, BIAB 2027 will need to be AS Native. Apple has been known to punt before. 2012 (Mountain Lion) was supposed to drop support for 32bit, then 2015 (El Capitán) but that did not happen till Catalina in 2019.
Seems that should be a priority...
Who's priority? I do not work for PGM but I
am an experienced hardware and software engineer who knew a couple guys named Steve when both worked for Atari. The following is my guess:
Problem, based on years of reading these threads, is that PG Music appears to have a large installed base of Intel Macs. There is no "reverse Rosetta" that makes AS Native only apps backward compatible once Apple drops support compatibility in whatever a future OS requires. That's a lot of users who become abandoned because the hardware cannot keep up.
I ran into this in 1995 when MacInTax year 1994 would not run on my Mac Plus. I still had to do my business taxes so running an older version could not be done. I was not happy, believe me. I had to buy a Performa 5200 till MacInTax wouldn't run on it, then a Beige G3, then... I may have had a different reason to buy my G5, that was 2002. Anyway...
BIAB over Rosetta II is quite fast. I had my current M2 Studio Ultra for over a year before I sold my iMac Pro and was able to speed test BIAB 2022–23 on both platforms. I still test it on my n2012 MacBook Pros running Mojave and Catalina — just because I'm curious.
