Dell Inspiron 17R Notebook (Inspiron 7720) - Can run Mac OS X

[naquaada]

Hello,

 

I've gotten my 7720 from retirement. Luckily I hade  a backup from my Mavericks system last used in 2020,

so I got it working very quickly. I have everything working, the HD4000 is patched to 2048 MB VRAM.

DIsplay brightness control also works. The trackpad is dead after waking up, but I created a workaround for this.

 

Has anybody managed to get double monitor working on the 7720? If I plug in a HDMI cable I have it on the monitor,

but the internal display turns black. I've tried various Capri Framebuffer patches, but none of them worked.

i would be a nice addon to get this working.
