@m-lo, could you fix the problem asl_ERR: UnAsmOpcode: invalid opcode class 0???? thanks!!


To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Hi. I've been using the DSDT override with testsigning set to on. However, I just bought and installed Ghost Recon Wildlands from Ubisoft and the game won't launch because it needs DSE to enable EasyAntiCheat. The solution they give on their site is:

bcdedit -set TESTSIGNING OFF


Won't this disable my DSDT override and render my eGPU unusable? Is it possible to do this and then re-enable Testsigning or does the game and EasyAntiCheat need it permanently on?

Does anyone know how to get around this? 



An alternative non-registry method of loading the DSDT override is covered in the OP:


I have the same issue with another game using easy anti cheat.

Is the non-registry method safe now? Or is there still a chance to brick my MacBook (pro retina early 2013)?

@thatpickleman, kryptonite and automate-eGPU EFI bootloaders both have DSDT loading capability that may be more suitable for use with Macs than Clover outlined in the OP.
