Hey there!

I am using Kryptonite for a while now, and while it works great, my Macbook crashes when going into hibernation mode. Almost every time. Do you think this might be sth. related to Kryptonite? Did I sth. wrong?

Thanks for the great work!

How do I inject DSDT overrides for bootcamp?

Sorry if this seems like a silly question-  Thank you

@germay, You can take a look at my 2015 iMac 21-in + R9 Fury X build guide to configure the DSDT override for Boot Camp.

@elluko, use the latest version of Kryptonite (re-setup your disk using the instructions on the github page).

@joevt, Hello, Thanks for your information, but it seems too complicated for my skills.

@itsage, Thank you @itsage.   I am using the latest build of Kryptonite.   Created the config file.   Used the DSDT file from here.  Is there a procedure to turn on the egpu  in windows?   On Mac OS you have to turn the egpu on then log out.   I am getting a black screen booting into windows after the logo and the circle of dots.  Thank you.

I immediately notice after 11.5 update that the sleep is now an issue with eGPU on. When I wake up the laptop I see eGPU disconnected improperly message. @mac_editor Do you think I have to rerun the kryptonite install?


UPDATE: After 11.5.1 and Kryptonite reinstall all is back to normal. Not sure what fixed what but I suspect the OS was at fault.

Hi there,

I'm in the process of attempting to setup a Razer Core X on my 2013 Mac Pro using kryptonite, and thus far have been able to get everything working (including the OpenCore workaround that enables automatic booting) with the exception of the fact that restarting causes my monitor to go black.  The only solution to this that I've found up until now is to restart again with my monitor connected to the iGPU so that I can then reconnect to the Core X, which then reenables everything.

Any thoughts as to how this issue might be resolved would be appreciated.  🙂
