Kext is not working properly on macOS 14.4+

[fivossak]

With macOS 14.0-14.3.1, we could use the -rtsfbeta boot argument to force the kext to load on an unknown OS version and that did the trick. Starting with macOS 14.4, the kext no longer works as intended. If you go to System Report -> Card Reader, it will display "There was an error loading card reader information" or something along these lines. My device is an RTS522A if that matters.

In macOS 14.5, it's partially workig. With the boot-arg -rtsfbeta the kext will load and infos about the reader are shown in System Profiles:

But no properties about the inserted SD card are displayed.

I just tested it on 14.5. With no card inserted, reader info is displayed correctly, but once a card is inserted, I get "There was an error while scanning for Apple Internal Memory Card Readers."

Is there any plan to support macOS 15? I tested with -rtsfbeta on macOS 15 beta but it did not work anymore. It shown volume name but not mounted.

Same issue here, from macOS Sonoma 14.4+, there is this issue

Well, the last update was almost 2,5 years ago. I guess somebody has to fork the repo and fix the kext.
