Hi!

I'm trying to install Mac OS Sierra on my desktop but I have a problem. I can't enter in the installation program. I got a black screen after the Apple logo.

I can access to clover and click on "Boot Mac OS X from OSX Sierra" and all the others options.

Here is my detailed situation: I got a black screen for approximately 30 seconds after the Apple logo and after I have some multicolour lines in the left side of my screen for 15 seconds. After, I have another black screen for 1 minute and my PC reboot.

Here are the multicolour lines : View media item 188483
Is there someone who know this trouble? I think is related to the graphics but I'm not sure.

Here is my configuration:

CPU: Intel® Core™2 Duo Processor E8400
Graphics: AMD Radeon HD 4850 512 Mo
MotherBoard : Intel E210882
RAM : Apacer 2GB UNB PC2-6400 CL5
HDD : Western Digital Blue WD1600AAJS 160GB

Also, I have a e-GeForce 8600 GTS that I take to test if the installation process work, without success.

I also try to install Mac OS X without graphic card(I removed and disabled it in Bios) and no success again.

A precision : I check the nVidia graphic injection option while creating my USB stick because my final installation will be on my laptop, with a nVidia 950M graphic card.

PS: My USB key seems work on my laptop(Asus N551JX).

So, this is my situation and my problem, did anybody could help me?

Thank you in advance,
Zacharie
