How exactly are we solving this common issue @tikikun ?

Namely, are we doing:

• Better error propagation
• What is the OS support matrix?
• From a docs perspective what needs to be documented for users to download the correct models?

Hi, I encounter the same issue.

I did open the dev tools and found an interesting bit:

Checking if something is listening on that port confirms us that it‘s not the case:

❯ lsof -Pi4 | grep 3928

❯ 

Next I tried to launch Jan.app from the CLI to see if I get some log, and indeed:

❯ /Applications/Jan.app/Contents/MacOS/Jan
Checking for update

(node:65741) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)

So this seems related to an embedded binary "nitro" that is crashing on startup.

Hope this helps
