Some of you may remember Sinetek's initial work back at the beginning of 2017 on the development of a macOS driver for those PCIe Realtek RTS card readers fitted to many of our laptops. Whilst Sinetek's work never fully completed and only reached limited success, Cholonam recently resumed development work for the RTS525a card reader of his Dell XPS 9350.
This resulted in great success in the sense that we now have a working driver for several RTS card readers, albeit with some limitations in respect of performance or supported hardware models.
The driver is available off Cholonam's Github repo.
Discussion on this new driver is available in continuation of Sinetek's original topic at insanelymac.
We've also reported on development progress of this kext in this thread where we invite owners of Hackintosh laptops fitted with Realtek RTS card readers to feedback their own test results.
Credits and thanks to Cholonam and Sinetek of course!
