…in days of m chip gen macbooks, unified ram and the actual ssd tech benchmarks, ur totally fine with 8 gigs of ram…days of the more ram the better are for most missions to be accomplished pretty much over…only thing u really must take care of, to get at least 512gigs of ssd capacity…
i really wonder how they still even dare to offer 256 versions…since they know, that’s the real deal that slows it all down and get’s overpopulatetd pretty fast, since u always better leave some 10 to 15 % of free headroom on ssd’s to make sure they last “forever”…once any sdd is forced too much to rewrite/reorder their segments, which they always do during processing to some extent, and got not enough free sectors left to use to do so while internal data swapping, they wear out pretty fast and will let u down…
the only real valid point that still speaks for more ram is “better”, is xactly this unified thing, which allows ur computer to also use the ssd as more frequent realtime ram support…
if u never wanna think about all this, the best and total nobrainer macbook config is 16 gigs of ram and a 1tb ssd…such a laptop will serve u well for at least a decade to come…but if used properly any 8ram meets 512ssd variant can count the same…
so any macbook wether it’s an air or a pro, no matter if it’s first m or latest m gen, no matter if it’s 8 or 16 or 32 gigs of ram will make u totally happy when it comes to common audio tasks of all kind…background processing/final renders might take a few seconds more or less overall, but that’s about it and does not make any difference for u as a single user with single tasks…
also all these different m gens really just diiffer, in essence, with the count of neural processing capabilties, which really comes into play when we start talking ai sort of stuff…no real need for now, when we’Re talking any sort of daw use…
at least if u don’t force it all up to 96k in constant realtime processing… 
and investing in an official live or, even better, a bitwig license, or, since ur an apple user, a quite reaonable logic deal, is another timeless and good investment u won’t regret…
and before u get lost in way too many vst’s…always give urself and ur daw of choice the time to really know what u got in there already before u give anything on top and in addition to all that a try…most of what u can get with third party plugins is already right in front of u, provided by the daw itself already, with way more cpu efficient internal tools…and nothing let’s u fly like u really intertwined with the daw of ur choice, knowing at least it’s most common shortcuts that can speed up ur workflow soo faar beyond any cursor clicking safaris all over ur screen real estate…
and no matter how many neural engines ur m chip has to offer, each of them will let u talk to ur daw from next year on… additional audio engineers for all of us…
