Hi All! This week I replace USB3 pcie card to thunderbolt Alpine Ridge (flashed). I tried to install it with Martin Lo original config, turned on the SSDT, of course the chipset was shown as Intel DSL7540, but Alpine Ridge should have 6540. Nevertheless, i plugged in Belkin thunderbolt dock with connected thunderbolt RAID HDD, did a warm restart - HDD doesn't show - in system info thunderbolt pci shown, but in thunderbolt section disappeared. Then i changed settings in config and replaced SSDT-TBOLT3.aml with SSDT-TBOLT3-AR.aml (Alpine Ridge SSDT provided by the card seller)- it works now. I still need to test the work for a long time, but I am not yet satisfied with replacing USB3 card with a thunerbolt card, since after sleeping and waking up all devices disappear, I need to turn off the CMP, boot the system, and then do another warm reboot. Since I have a backup disk connected via thunderbolt to the Belkin dock, and now it’s obvious that I won’t be able to make a recovery from time machines. if I need to restore the system, I will have to put the backup disk inside the cMP. Or did I something wrong with set up the thunderbolt card? and your cMP works differently?
ADDED after a whole day of testing: I found that if I don’t use Belkin thunderbolt dock, but connect HDD devices directly, then the work becomes more convenient - I have one thunderbolt connected to WD MY Book Thunderbolt Duo - in SysInfo it is shown as a thunderbolt device, and the second to WD My Book Duo - it is shown as USB 3.1 device. When turning on or rebooting the cMP, external hdd are now shown. And I can even make a recovery from an external time machine. BUT IMPORTANT!
the disk that shows up as connected to usb 3.1 I can eject (using mac os eject command) and reconnect again, then if I try to disconnect the disk that shows up as a thunderbolt, the system immediately crashes, the cMP tries to reboot, the GPU crashes - the display shows a damaged picture. Neither reseting sms nor reseting nvram helps, and the system boot freezes. I found, that for some reason, EFI opencore is damaged. Only a complete overwrite of the entire EFI returns the cMP to work (even without resetting SMC and nvram). STILL IMPORTANT! after sleep and wakeup, HDD is not visible again, if I try to replug HDD, the system immediately crashes and the result is the same as described earlier. In order not to crash after the sleep and wakeup, I have to turn off and boot the cMP with the devices DISCONNECTED from the thunderbolt, and reconnecting again after the system boots. And after a warm restart, then the hdd is visible again. cMP works as usual, it can be turned off and after turning on the HDD are visible and working. For me it is impossible to make any manipulations with connecting and disconnecting devices while cMP is ON, except for the procedure described above. My question is, how does it happen that the EFI is damaged? how to avoid it?
