Hi
I am running 3 screens on my MacBook pro, up until this morning everything worked fine, now as soon as I add the 3rd screen my MacBook freezes and I have to force restart my machine?
One screen is running via the HDMI port and I have the other two on Griffin HDMI thunderbolt adapters.
I did find that if I leave the HDMI connector plugged in and unplugged the two thunderbolt ports, then first plugged in the thunderbolt port closest to me, then the other one, it works without freezing. But if I try to plug everything in first then startup, it freezes, in fact any other configuration makes the MacBook freeze.
Also this is only since upgrading to Sierra.
Anyone have any ideas?
I am running
MacOS Sierra 10.12 (16A323)
MacBook Pro (Retina, 15-inch, Late 2013)
Processor 2,3 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GT 750M 2048 MB Intel Iris Pro 1536 MB
The displays I'm running are all:
DELL S2340L Display, 23-inch (1920 x 1080)NVIDIA GeForce GT 750M 2048 MB graphics
MacBook Pro with Retina display, macOS Sierra (10.12)
