Administrators Hervé Posted April 7, 2020 Administrators Share Posted April 7, 2020 There is renewed development on the matter of Realtek's RTS52xx SD card reader building on Sinetek's initial work : https://www.insanelymac.com/forum/topic/321080-sineteks-driver-for-realtek-rtsx-sdhc-card-readers/?do=findComment&comment=2713476 https://github.com/cholonam/Sinetek-rtsx I've tried out Cholonam's Sinetek-rtsx kext v1.0 on my Latitude 7490 and it's now possible to read (and only read) an SD card once inserted in the reader. It can be ejected and re-inserted at will; it's just a little slow to mount (~10s) and Read-Only. Works after wake too. Supported models appear to include: RTS5209 / RTS5227 / RTS5229 /RTS522a / RTS5249 / RTS5286 / RTS5287 / RTS5289 / RTS525a 1 1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 20, 2020 Author Administrators Share Posted April 20, 2020 Cholonam has now issued a version v2.1 which appears to work for some of our Realtek RTS52xx car readers. https://www.insanelymac.com/forum/topic/321080-sineteks-driver-for-realtek-rtsx-sdhc-card-readers/?do=findComment&comment=2718154 https://github.com/cholonam/Sinetek-rtsx/releases I've tested the driver successfully on my Latitude 7490 fitted with Realtek RTS525a microSD card reader. I experienced a read/write limitation to 5MB/s max. It was reported to Cholonam who is aware of this. Other than that, it works fine. It's probably the best we'll get for some time as Cholonam indicated he was unlikely to pursue work on his driver given that it works for the RTS525a card reader of his Dell XPS 9350. If that were the case, hopefully someone will be able to pick from there and resume work in the future. Please note that I've only tested this driver under Catalina since that's the only version I've got installed on my Latitude 7490. Would be grateful if people would feedback with their own tests under other macOS/OS X versions. Also note that if Clover is booted off the microSD card, laptop will need to be put through 1 x sleep/wake cycle to initialize access to the card.
