Second display problem with 10.9.4

Please file a bug at https://bugreport.apple.com -- they don't officially read this forum, only users are here.

Theoretically, if enough bugs are filed against this, Apple will deign to fix it for 10.9.6 as well as make sure they don't release 10.10 broken from the get-go.

Running 10.9.4 with GTX 770 with MacPro 3,1. This has solved my issue. Second monitor on DVI-D port now is working. I am going to attempt to install CUDA to see if I can get back to work with Premiere.

gatd4's solution worked perfectly for me! It might not work for non-NVDIA Macs, but it worked on my 2008 Mac Pro. Thank goodness - good luck!

Try SMC and PRAM reset.

And trust me, I've been an Apple user since '88, and Steve Jobs was just as capable of screwing things up as anyone else (he was not a perfect man). I still miss him but I'm not going to blame any problem that occurs because Steve is not there any more.

Rather let Apple know there is a problem, as this forum is just a way to get fellow Mac users to try and help.

I also called tech support and im with a senior technician. under 10.9.3 my display thunderbolt to displayport was working. under 10.9.4 not anymore. i ccidentally told the support it was thunderbolt / minidisplay to dvi instead of displayport.

but since i read you guys have the same problem with dvi, i guess it was still right to do so. and i also guess apples engineers must have seen what kind of connection it was, displayport or dvi right?

anyway, they had logs from 10.9.3 and 10.9.4 . now they called me again and told me they would send me an apple minidisplay to dvi. and see if this works. i guess ill be getting it on friday and check. still though i dont get why they cant figure that out.

Telling us (fellow Mac users) will not improve the situation. You need to communicate with Apple.

With cautious hope, i note that they re-classified my filed bug (17083693) no longer as a duplicate of another issue and re-opened it, now asking for the dongle make and model i'm using. (This happens for me with either a "Apple Mini-DP to Dual Link Adapter" (Part Number: MB571Z/A) or a Cable Matters DisplayPort cable). ...fingers crossed for a 10.9.6 fix...

You should really file a bug at https://bugreport.apple.com/ -- the more data they have, theoretically the better they might be able to fix their display issues.

(I'm ignorant on that model of the MB Pro, but the tech specs list two graphics chipsets (the on board Intel HD 4000, and the NVIDIA GT 650M) -- is one driving the laptop's screen and the other is devoted to whatever external displays there may be? )

When both screens go black forcing you to reboot, have you tried instead (if you have another machine on the same network) SSH'ing into your laptop and killing the WindowServer process? It's plausible that kicking it into restarting itself might rescue the display in the new configuration so you needn't reboot.

I wish the altoronto solution worked for me, but now instead of it periodically sending a signal out the displayPort / thunderbolt, it no longer does ever.

I got a reply on my Apple bug saying 'we think this is fixed in the Yosemite Developer Preview, could you please try that.', which underscores how incredibly out of touch Apple QA is with its user base; to presume that i could simply take the machine i rely on for work and install less than beta software on it, is totally cuckoo banana.

(... and the implication that they won't bother fixing this for Mavericks but instead rely on the notion that users will suffer through the regular crappy quality of Apple's dot-dot-0 and dot-dot-1 releases of new OS for a fix is somewhat infuriating.)

I'm surprised the altoronto solution is not a fix for most.

It's unlikely to be anything other than a software issue in my eyes.

Have you guys meticulously followed his instructions and dragged each and every "windowserver" filename to the trash in the locations specified. There is a great wee app called "EasyFind" which is good for making sure you haven't missed any. If you have gone at it half-heartedly because there are a million possible solutions on this thread now, give it another go "like a BOSS!!"

finally got mine to work with a cheap hdmi cable and dvi/mini adapter. dvi still doesn't work though. if anyone does roll the dice and upgrade to yosemite, and it works, please post. this is so ridiculous. i have a 2008 macbook unibody and i never should have upgraded to mavericks to begin with, but it was running so slowly, i felt i had to.

I, and others have the same problem. this is a bug. i escalated it to apple. tried a fresh install on a different partition etc. i have thunderbolt to dvi on a dell 2406m... external display.

None - please file a bug with https://bugreport.apple.com -- maybe they will fix it in 10.9.6

on a mac mini (mid 2011) same issue since 10.9.3

VERY annoying since mac mini doesn't have a internal display....

Mid-2011 Mac Min specs:

Processor 2,7 GHz Intel Core i7

Geheugen 8 GB 1333 MHz DDR3

Videokaart AMD Radeon HD 6630M 256 MB

now running: OS X 10.9.4 (13E28) (issue occurred since installation of 10.9.3)

Display: EIZO S2433W

Connected via a daisy-linked thunderbolt-connection (in between is a La Cie Thunderbolt drive)

An APC UPS is connected (I just mention it, because some are referring to stand-by settings)

95% of all "wake-ups" I need to power-cycle my monitor to restore image....😟

Guys i have this same problem and have just created a ticket as suggested.

I will be keen for a resolution to this as its a real PITA. I can get the second screen to work by plugging and unplugging the monitor a few times, i really need the screen real estate!! Argh!! its doing my head in..
