Guest twoheartsinthedark Posted October 30, 2024 Posted October 30, 2024 Hi all, I have a second hand 2013 Mac pro 6,1 (Trash Can). If I just let it boot normally into the OS (Mac OS Monterey) it boots fine with good audio and video. However if I shut down and hold the OPTION key right after the startup chime I never get any video. The screen remains black and the monitor flashes no signal. Is there a fix/work-around for this? thanks Frank Source: MacRumors
