I'm not sure if this information was already known, but I came across it today and wanted to document it somewhere/somehow.

I know for firmware downloads today, Mist is using the API at https://api.ipsw.me, but in case we ever want to cross verify from an official Apple source, or switch to only pulling from an official Apple source, it appears that Apple's official listing for IPSW files is at https://mesu.apple.com/assets/macos/com_apple_macOSIPSW/com_apple_macOSIPSW.xml

There was a previous discussion in #25 in regards to pulling IPSW data, but the reasons why may not be obvious in the thread.

From what I can see / remember, com_apple_macOSIPSW.xml doesn't provide all the metadata you would hope for when running mist list firmware:

Metadata Available Notes
Signed ❌ Not present
Name ⚠️ Name could be translated from ProductVersion key
Version ✅ ProductVersion key
Build ✅ BuildVersion key
Size ⚠️ Not present - could verify download against FirmwareSHA1 key but this would be post-download
Date ❌ Not present
Compatible ⚠️ Not present - could compare against remainder of metadata to build a compatibility list on-the-fly

Even if we were able to find a workaround for all of the above, the biggest issue we face is that com_apple_macOSIPSW.xml only seems to return information for macOS 12.4:

➜ curl https://mesu.apple.com/assets/macos/com_apple_macOSIPSW/com_apple_macOSIPSW.xml --silent | grep ipsw | sed 's/<string>//' | sed 's/<\/string>//' | awk '{ print $1 }'

Would 💯 trade 3rd-party APIs for an Apple-only implementation, just not sure how to solve this one yet 🤔

Might be worth adding the Apple MESU url as a fallback such as when the IPSW.me list is being updating? Or maybe that would just confuse users since only the latest would ever be listed with minimal details.
