Description of issue

Hi all.
I'm about to migrate from my old MacBook Pro with Intel CPU to a more recent MacBook Pro with M1 CPU.
Now I've just run "brew install" with the list of software I had installed on my old MBP but some of them won't run. Maybe because of not being the M1-versions. Is there a way to identify these, so that I can install the correct versions?
Thanks,
F.

don’t forget to install Rosetta2 on your new M1 Mac, for maximal flexibility in running software.

It’s not installed by default.

[FlavioB79]

Oh, so I just have to install Rosetta2 and that's it?

[SMillerDev]

It really depends on the software. Some software only runs on Intel. Some software you can run on arm in Rosetta and some will just work when you run brew install

[FlavioB79]

OK Thanks!

Adding onto this: if there is a separate arm64 version of a cask, and we know about it, brew will install that automatically. You don't have to specify anything.

Thanks for this additional info too.
