Sorry to break the news, but I guess we are in the 1% territory. No version of Obsidian runs on Apple Silicon as of now via Rosetta 2. Electron apps, like Slack, need to be updated and—so far—Slack is the only one that did it.
Eager to see an update, because I’m considering Roam otherwise. At least that one has a web interface if the Electron app is not brought up to speed. The attached image is Obsidian’s window on Apple Silicon. Having one of those here, I’d be happy to test any early release to make sure it works when it will be inevitably needed and required by many users.
