Second External monitor not working after update Sonoma 14.6.1.
I have two Samsung Monitors M7 & M8, both connected to the Thunderbolt ports
The M8 stop working using Thunderbolt Port. Using HDMI still work.
Mac mini, macOS 14.6
Same. However, unlike those below I've had no luck in fixing this. Various rounds of unplugging and powering down, etc. I work on a single external monitor with the mac closed. Never had a issue until just now when installing this update (14.6.1). I use HDMI cable through a iVanky FusionDock 1+. MacBook Pro M1 2020. No ability to use thunderbolt cable with my monitor.
This is what worked for me.
Having the same problems on all 3 Mac’s. Mac Mini Studio with M2 Max running 14.6.1, MacBook Pro with M2 Pro and MacBook Pro M1 Pro both running 15.0.1.
