Multi displays on Mac OS X 10.9.3 with the new Mac Pro

[Thierry]

Hello Mac users,

A bug has been found on Apple's forums that affects people having the new Mac Pro with the newest 10.9.3 version of MacOSX.
If you have more than 2 monitors, then the third (and those after) may not display anything.
This behaviour can also happen on the MacBook Pro Retina 15" if you plug a monitor on the HDMI port.

So, until Apple decides to fix this, I advise you to not install the 10.9.3 update of MacOSX and stay with the 10.9.2

Hey !

anything new about this topic ?

I just found out about it. I have 2 monitors and now the new apple can ONLY make you use one. This is horrible.. I used the second monitor for all the layers and stuff. How can we use the second monitor again ??

Thank you xx

Well, you should ask Apple directly.

Hello again !

I forgot to say that I use a cintiq 24HD, imac 2013 OSX 10.9.2 and it is impossible to now stretch the windows to the next screen. I only can use one at a time.

When I looked at the topics, it is said to do that only on the 10.9.3. so I don't get what's happening.

Help !

Thanks you in advance

Found a solution for the stretch windows to the next screen :


If you prefer the old behavior, uncheck the “Displays have separate Spaces” checkbox in the Mission Control preference pane. Doing so will also restore the ability to have windows that span more than one display. You know, for old times' sake.
