Hello!
Can’t get meteor 2.7.3 running on Mac M1. Getting this error Bad CPU type in executable:
=> Started proxy.
=> Started HMR server.

Can't start Mongo server.
MongoDB failed global initialization
When I checked mongod in this directory file …/mongod it says that it’s for x86: /mongod: Mach-O 64-bit executable x86_6
I’m not sure about this solution, but I had similar problems, and re-installing meteor fixed it for me.
The other option is to run mongo as a separate process, and use something like this
MONGO_URL=mongodb://localhost/my-database meteor run
This also has the advantage that a meteor reset doesn’t blow away your data

Thanks, probably I will go this way.
I’m not sure about this solution, but I had similar problems, and re-installing meteor fixed it for me.
I did it multiple times with different versions. The strange thing is - I downloaded tarball with installation manually and I found that the bundled mongod is for x86 architecture. I tried to replace it with arm64 version I installed separately but again I got the same error.
It seems to me that rosetta is not required for meteor itself but it does required for running mongodb in development… 
Has this been resolved? If so, please explain how.
I gave up for now. Will try to run MongoDB as a separate process when I have time for experiments. Using rosetta terminal should help too.
I had the same problem, I solved it with install meteor with npm install -g meteor instead or sh script and it works

Same here, not sure why but it only works with npm install -g meteor
I’ll ask to someone to take a closer look into it
