Monitor not waking up after 10.9.3 update

Hi,

I am using the Mac Pro 2013 and have run into some monitor issues after updating to 10.9.3

I am using a dual monitor setup, the SamsungA950 and the Eizo CG275W. Ever since the 10.9.3 update, the Eizo monitor will not wake when the display goes to sleep and I try to wake the computer up.

I know the computer is still running as the other monitor comes up and I can see the mouse cursor. I have to physically unplug the Eizo monitor from the Mac Pro and then replugging it before it will appear after a while.

This issue did not occur before the 10.9.3 update. Anyone sees this with other monitors too?

iPhone 5, OS X Mavericks (10.9.3), 12core 2.7Ghz, 64GB RAM Dual D700

Yes, something similar except I have to restart the rMBP to recognize mt LG monitor. Often the rMBP freezes (except for mouse).

I've noticed that if FCP 10, Aperture, or Mac DVD Ripper pro is open when the rMBP goes to sleep, these apps have to be quit before the external monitor is detected. Seems its worse when the apps have a window on the external monitor.

You may want to check this awkward behavior with 10.9.4 beta if you can.

This is not fixed in 10.9.4 beta. It just happened again. I used to force-power cycle when it happened by pressing power button, but there is a better (or safer) way.

Command-Control-Media Eject : Quit all applications and then restart the computer

Command-Option-Control-Media Eject : Quit all applications and then shutdown the computer

I don't think my rMBP has a media eject key. I think Command E is the same as the keyboard eject key

I have just installed the 10.9.4 beta and my eizo monitor is waking up fine now.

It is definitely better than 10.9.3, but it will happen again eventually.

I'm having the same problem but did find a work-around. I stream some audio (like a radio station) -- when my Powerbook and thunderbolt display go to sleep, both wake up normally as long as audio is streaming (I actually mute the audio so as not to be distracted). It's a drag to be forced to do this, but it allows me to work until Apple REALLY fixes it...

What I do is, set the monitor to never sleep and turn off the TV (in my case) manually.

Should I turn on monitors first and then wake up the Mac Pro? Or it is the other way around?

Jun 28, 2014 2:14 PM in response to vett93

When the Mac wakes, it will send out the EDID query.

The monitors must be ready to respond to that query, or they will stay dark.

Yeah that is what suppose to happen, along with a discovery sequence. Do you happen to have the traces to prove that for 10.9.3? 10.9.3 seems to have broke something and its not working the way it should.... seems slow to respond and time out happens. Seems to not send and EDID when FCP or Aperture had a window open on the external monitor when the Mac went to sleep.
