Mac OS 27 Golden Gate: Error launching site

What issue or error are you experiencing?

After upgrading to Mac OS 27, starting site fails with

Error: spawn Unknown system error -86

at ChildProcess.spawn (node:internal/child_process:441:11)

at spawn (node:child_process:810:9)

I pulled the site files to the desktop, zipped them and tried reimporting it, but got the same error.

What steps can be taken to replicate the issue? Feel free to include screenshots, videos, etc

On Silicon Mac with MacOS 27, start previous site.

Looks like MacOS 27 removes Rosetta (a preparation for OS 28?). Local must be using some Intel resources.
Installing Rosetta again makes Local work again.
softwareupdate --install-rosetta --agree-to-license

Local no longer uses Intel binaries by default. It’s fully Apple Silicon compatible for fresh sites.

If you’re using an old version of PHP, though, that might still include an Intel binary. You could try upgrading the PHP version for any sites that won’t launch — this helped two other Local users here:
