I too am sitting in a similar place.
I use a Mac and a PC. While they are mostly the same, there are some differences.
My MacBook Pro is almost 9 years old and I'm considering a replacement.
At that time I expect I will abandon BIAB win and crossgrade to BIAB Mac.

I wish to purchase a brand spanking new computer, not a refurb or used model.
I'm probably not going to do anything for at least 6 months, maybe longer

The new Apple Silicon machines have just hit the street. The reviews have been mostly positive but not entirely.
Changing the CPU chipset is a significant issue. I would like for the dust to clear a bit.

BIAB Mac does not run on the latest version of the MAC os. That is a hard no go to me.
I expect when it does run, it won't be without problems.
Not interested in spending a lot of $$$ to be a guinea pig.
I'll give it some time and avoid as much of the problem as possible.

A new batch of Apple Silicon MacBook Pro's are expected out by the end of the year.
For me that's a likely time to upgrade.

But that's just me.
