- Accessible uses Shortucts and various actions to read/extract system files.
- It combines this actions with a URL, starting with
file:///
. This URL is the path that Accessible reads at.
- This cannot read the entire filesystem. It can only read stuff in /Applications and /System.
- This "bug" isn't very notable, however it is useful for reading files such as MobileGestalt for on-device SparseRestore apps, and it can also be used to open apps not usually available to the user.
- Accessible has been taking advantage of this "bug" for a while now, however it seems that Apple has caught on.
TL;DR: Apple changed the way of reading files with file:///
, causing Shortcuts to not be able to read files from that URL.
