troorl Posted December 9, 2020 Share Posted December 9, 2020 Hi. I've had this exact problem with Mojave, and back then it was enough to replace AppleAHCIPort.kext. This time around I followed the Opencore guide and injected the patched CtlnaAHCIPort.kext (after blocking the original kext in the Kernel section). The kext is loaded, but the problem remains. Does anyone know how to deal with it? Link to comment Share on other sites More sharing options...

troorl Posted December 9, 2020 Author Share Posted December 9, 2020 Thanks, but from what I understand, it simply hides the drive from the system. My drive is perfectly functional and I want to use it. It's located in the caddy, I forgot to mention. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 9, 2020 Moderators Share Posted December 9, 2020 Try adding this patch under the kernel Identifier = com.apple.driver.AppleAHCIPort Count=1 Find = 40600200 Replace = 00000000 Comment = Patch Hotplug / Caddy" Link to comment Share on other sites More sharing options...
troorl Posted December 9, 2020 Author Share Posted December 9, 2020 Thanks for the suggestion, but unfortunately it didn't work for me. I'm actually not sure which of my two drives is in the caddy. It may be the current one. Link to comment Share on other sites More sharing options...

troorl Posted December 9, 2020 Author Share Posted December 9, 2020 It works! Very appreciated, it was almost the last thing that I struggled with. Interestingly enough, the system treats the partitions on that drive as removable. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 9, 2020 Moderators Share Posted December 9, 2020 Well, the caddy drive is removable like the DVD rom drive that's in that slot Link to comment Share on other sites More sharing options...
