Hi, everyone!

Three days ago, released the latest v 0.12.0 of the SDK!  
I am using m1 mac and dfx upgrade failed. Do you guys generally switch from arm64 to x86\_64?

```bash
$ dfx upgrade
Current version: 0.11.2
Fetching manifest https://sdk.dfinity.org/manifest.json
New version available: 0.12.0
Error: Failed to get latest release for version 0.12.0 and architecture x86_64-darwin.
