Hi all

All I've done: Plug in akitio thunder2 with 1050 ti using Apple adapter, got error code 12, after installing drivers. Disabled some PCI root controllers (one for FaceTime camera, other for Wifi). Reboot, seemed to work just fine.

Return next day and screen flickers, speakers are not working. Takes long time to boot. Same error 12,, when finally goes in, but this time screen flickers, and windows logo bleeds in the back. Very tripply. Even when rebooting into macOS! screen flickers and windows logo from bootup is stuck there. Anyone know what's up? How can I remedy this situation? Thanks all!

This happened in my 2016 Macbook Pro also after I successfully bootup my windows bootcamp and installed nvidia driver for GTX 1060. It went black so i decided to force the OS to power off.  

When i booted to MacOS, there is a flicker in the screen. But when i boot to Windows bootcamp, there is no flicker.

I decided to reinstall my MacOS from recovery, but the flicker did not go away, so i decided to bring the macbook to the service centre for warranty 😀 after few hours when i was about to leave, i checked again and the flicker is gone until now.

I have not tried plugging in my akitio node since because im afraid it was affected by it. (not sure though)

Hi guys, yes thanks. Yeah I noticed letting it sit for a long time it will go away eventually. 

 

ITsage, I'm using an 100 watt power supply (can deliver 12-19v at ~8amps)

ill try the default brick! But this flicker thing is scary. Should I do a dsdt edit? How hard is that? I've got a base model 13 '16 MBP

Do you also have a non touch bar MBP or touch bar model?

Did you disable pcie root controllers?

Mine has a touchbar. 2016 MBP 13inch.

I did not disable anything.  I just did csrutil disable in the recovery, installed intel tb3 driver, then booted to windows bootcamp while the akitio node is plugged in and powered.  It was working as my external monitor shown a display, until i installed the nvidia drivers  which made my screen turn black so i powered  the macbook off by pressing/holding power button.

CSRUTIL disable? what's that? moreover, are TB3 drivers necessary? 

 

I stupidly thought all of this was plug and play 🙁 Anyone have any tips on getting this to work? I don't want to give up on quiet performance and buy a loud plastic gaming laptop haha

Thanks itsage

 

Switching to the stock power brick, I don't get that flicker anymore. And disabling facetime and wifi PCI root controllers, no more error 12, however, no speaker output or headphones. DSDT the way forward, or ?

The stock power brick would not be enough for a GTX1050Ti under load, or it will be running outside of specifications. You need a good power brick to replace it with. For the basic install, however, with the card mostly idling, the stock power brick should do fine.
