📷 Screenshots
@F1248 the error message is a little misleading - essentially the issue is an invalid download URL.
For example, the IPSW.me API (used to retrieve Firmware metadata) reports back the following URL for macOS Big Sur 11.0.1 (20B29):
This is a HTTP URL, which is inaccessible (by design) due to App Transport Security.
The easy fix is to convert these HTTP URLs to valid HTTPS ones, for example:
Replacing http://updates-http.cdn-apple.com with https://updates.cdn-apple.com dynamically should be enough to fix this issue.
Will keep you posted 👍
