Download of backend crashes on Mac OS #8016
Description
LocalAI version:
v3.9.0, installed on my mac with #6268 workaround
Environment, CPU architecture, OS, and Version:
Darwin MACAPOSTOLYM1.local 25.1.0 Darwin Kernel Version 25.1.0: Mon Oct 20 19:32:47 PDT 2025; root:xnu-12377.41.6~2/RELEASE_ARM64_T8103 arm64
Describe the bug
when trying to install a backend via the UI (or when the backend is tried to be downloaded automaticly I think it does the same) I get this error displayed in the UI : "Error installing backend "metal-whisper": not a valid backend: run file not found "/Users/myuser/.localai/backends/metal-whisper/run.sh""
If I look in /Users/myuser/.localai/backends/, I can see that metal-whisper has been created, but it's completly empty
To Reproduce
Install on mac, try to download a model / a backend
Expected behavior
things working like normal
Logs
In fact it seems that it's linked to the launcher app on the mac launching on 8080 by default. I can access on 127.0.0.1:8080, but then dowloading fails. If instead of launching throught the app I launch the bin with --address=":8080", it tells me that the port is already in use. So I tried --address=":8081", it launches and now the backend are downloading properly
