Hello,
for many years my early 2008 MacPro worked very nicely under El Capitan. After being unable to synchronize my iOS devices I decided to test OCLP and made a direct jump from El Capitan to Monterey. That worked nicely but I wanted to fix the WIfi and bluetooth issue and changed the stock bluetooth module. Bluetooth worked from now, however a number of apps were jumping only and did not start anymore, so I wanted to make a clean new install from USB stick to the dedicated SSD. I got stuck in an endless loop booting to the recovery screen and then I made a core mistake (not reading properly the section on "Infinite Recovery OS Booting": https://github.com/dortania/Opencor...ROUBLESHOOTING.md#infinite-recovery-os-reboot), I did a NVRAM reset. Since then, my Apple LED Cinema 24" remains black. I can hear the chimes and some more typical "starting noises" and I assume that the bootpicker or the recovery screen may be displayed, however, I cannot see anything as there is just nothing on the display. Unfortunately, I do not have any other display that I could connect, only MacBooks around. I have made NVRAM resets earlier (before OCLP) and did not have any display issues, so I am guessing that OCLP has written something to NVRAM what is necessary to communicate to the LED Cinema screen, and this setting is overwritten now. I tried several more NVRAM resets but to no success. Any ideas what I could do?
OCLP 1.3 Monterey
MacPro 3.1, 2,8 GHz Quad-Core Intel Xeon (Xeon(R)) CPU: 4-core, 10 GB RAM
NVIDIA GeForce GT 120 - VRAM: 512 MB, LED Cinema Display 1920 x 1200
