Jul 3, 2014 5:52 AM in response to Jerry Chrismanby James Weisbin2,I'm trying to understand if the crash happens because the monitor has gone to sleep, or if the system has gone to sleep. On the new Mac Pro's, in System Prefs/Energy Saver, there is an option to "prevent computer from sleeping even when display is off". If this is checked, does the system still crash when the monitor wakes up? If not, then that would be an easy workaround.
My point is, other than saving wear and tear on hard drives (which can be set to sleep independantly) - and this doesn't affect the boot drive, which is SSD and doesn't benefit at all from "sleep" - there is no compelling reason to set your machine to sleep.
It's still a bug, but the question is, is there a workaround?

Jul 5, 2014 7:53 AM in response to isengrabby miguel_forum,i have the same problem but i was pacient to wait for the 10.9.4, unfortunately doesn't work properly also
tomorrow i want to do the same you did, jump back to 10.9.2. my is a MacMini 2011 and original OS is the Lion, thats where i have to start back, my problem can be when i update to 10.9.0 the Apple system will do an automatic update to 10.9.4 without asking.
how did you manage to install the 10.9.2 without updating to the last level?
tips are welcome

Jul 18, 2014 2:00 AM in response to James Weisbin2by Nagus,I just send this report to apple bug report:
I think I have narrowed the problem down! I just tried to test one monitor with the apple active mini display port to dual link a adapter. the process of going into sleep and waking up again (without the „out of range“ error) works without problems as long as there is enough time that the monitor fully goes to sleep. when i try to interrupt the „going into sleep“ mode with a press of a button, it get the error! so if i give the monitor a few seconds to complete the process, it’s fine. if i immediately stop the sleep mode on the first sign, i get the error! BUT ONLY WITH THE ACTIVE ADAPTER! the passive apple adapter working on all three monitors without a problem! and it’s not a defect with the one display because i also tried the active adapter on the other two display > same problem!
The displayed error "out of range" disappears, when i turn the monitors off and on again with the main power switch!

Jul 18, 2014 3:14 AM in response to Nagusby miguel_forum,my configuration, in my opinion, is much more simple
Macmini - HDMI cable - TV (LED full HD)
on preferences, no sleeping for system, no sleeping for hard disk, no sleeeping for monitor, no sleeping at all, it is a server running don't need to have a rest.
It worked perfectely until 10.9.2, I could switch on and off or change the sources in my TV and I got always back my screen from the Macmini. After 10.9.3 and 10.9.4 DOESN'T WORK anymore, there is some tricks that i can do to get it back, as for example unplug the cable and plug it again, or access the Macmini with my MBP (Share Screen) then in the system Preferences - Display and I change from 1080p to 720p and then back to 1080p ... but this tricks are all b**ls***t, they work for one time, next time it will be dead again.
I went back to 10.9.2, which gave me about 24hours work to re-configure all in the server, even using backups, but it is running as it should. I will never update this Macmini, without doing some paralell tests. so, at the same time i created a smal partitition 20GB on my main harddrive, where I keep the last OSX version running and I can test if it works or not.

Aug 13, 2014 1:56 PM in response to SteveJobsDotNetby joe12032,I just bought one of these LG 27MP35HQ monitors but it wouldn't work on my iMac, I wasn't able to make any setting adjustments to the resolution/colors etc. What am I missing in order to use this monitor, can you offer suggestions?
I connected it using DVI cable and adaptor.

Aug 13, 2014 2:40 PM in response to joe12032by lllaass,This is the Mac Pro desktop forum. The discussion is for problems with the new (late 2013) Mac Pro.
Try posting in the iMac forum and please identify the specific iMac you have.

Sep 19, 2014 2:46 AM in response to lllaassby Jerry Chrisman,Wanted to let everybody know that as of 10.9.5, Apple has still yet to fix this bug. It's making my head explode. I have to restart my computer once a day. Intermittently, waking from sleep kills 3rd monitor.
I am so frustrated. Billions of dollars of talent and they can't seem to fix this despite bug report after bug repot. I am a power user and an Apple developer, not some casual user who bought their iMac from the mall to check email and download Selana Gomez tunes from iTunes. So sick of this.
It's very Microsoft-esque.

Sep 19, 2014 11:12 AM in response to Jerry Chrismanby vett93,Check out this thread Jerry: Mac Pro (Late 2013) Dual monitors freeze on startup?
On Page 4 reported by Volt-Mac, he found an active adapter that is helpful. My Mac Pro has the startup freeze and monitor wake up problems for the last 3 months. I got one of these active adapters from Amazon. My MP's issues may take 7-10 days to show up. So far so good though....

Level 1 (15 points)
Servers Enterprisekeep away from the 10.9.5, they did not solve it yet.
but what it is strange is the 10.10 Beta 1, Beta 2 and Beta 3 are working perfectly means we just have to way for the Yosemite release
i am keeping all my computers at 10.9.2 is the last one that worked without any problem, i just keep trying the updates with an external FW hard drive to keep myself out of troubles.

Oct 17, 2014 11:11 AM in response to James Weisbin2by isengrab,OS X Yosemite is out - can anyone confirm the regression introduced in 10.9.3 with multiple monitors is fixed in 10.10?

Oct 17, 2014 11:34 AM in response to isengrabby therandyzone,Not for me… still no second monitor on my 2008 Mac Pro. It's a genuine shame.
The kext fix worked on 10.9.3 and 10.9.4, but not on 10.9.5 – I couldn't even boot up. So I haven't tried it again. If anyone does try it, please let us know.

Oct 18, 2014 6:44 AM in response to isengrabby isengrab,I am happy to report that my issues have disappeared in 10.10! I recall many of us including OP starting encountering issues with the new Mac Pro and for me these have disappeared.
I have four displays connected to the new Mac Pro. 2 HDMI Samsung displays connected with active adapters and 2 DVI Dell displays connected with active adapters. I'd be happy to change my monitors around to other configurations or try using passive adapters to see if I lose functionality to help others identify whether 10.10 would solve their issues as well. Good luck!

Oct 18, 2014 10:28 AM in response to isengrabby vett93,Did you have the active adapters when you had 10.9.x? I had a lot of problems with 10.9.3-10.9.5 when I did not have the active adapters. After getting the active adapters, my Mac Pro has been very reliable with 10.9.5.

Yes, with 10.9.2 I had the same four active Accell adapters. The moment I upgraded to 10.9.3 I could only use two out of the four monitors regardless of which of the six ports available on the Mac Pro. As someone who breathes the software lifecycle for a living, it clearly looked (and still does) like a regression introduced in software, specifically in 10.9.3. It was easy to find OP's identical issue since I could identify the exact moment my setup broke.
You will have what looks like problems when using passive adapters, it's certainly confusing. Active adapters are a must if you're driving a third DVI or HDMI display from one card. See Mac Pro (Late 2013): Using multiple displays and http://www.overclock.net/t/721931/active-vs-passive-displayport-adapters-the-tru th
for more on these topics.
But again, just in case it gets lost in the noise, for me - using four external displays (2 HDMI w/ active Accell adapters, 2 DVI w/ active Accell adapters) with 10.10 works.

Oct 20, 2014 4:12 PM in response to isengrabby Gene Pope,Just upgraded to Yosemite and the 10.9.3 missing third display bug is back. Everything worked fine before the upgrade now it is just like ti was in 10.9.3. Odd thing is that I have three monitors, the new startup gauge appears on the left monitor but after startup the middle and right monitor work and the left monitor is black. Sometimes occasionally though the right monitor will be black and the left and middle monitor will work.
I have officially retired my apple fan boy hat....
