Applications move between spaces when connecting/disconnecting second display

During the day I'm constantly connecting/disconnecting/reconnecting my 2nd display to my Mac. When I do that a lot I see a few things happen:
- Applications move to different spaces
- One or two of my spaces dissappear
Has anyone come across this issue before and is there any solutions or options I can try out.
Many thanks!

I just ran a hardware test (on ML you must hold down Option-D so it can access the hardware test bits via the 'net) and the test completed without finding any issues. I wonder if the issue has to do with switching between the integrated and discreet graphics.

Spaces - Automatic re-arranging when connecting/disconnecting external display

In my role I have to constantly disconnect and reconnect my external display. When I do this my spaces rearrange and the applications within those spaces also move around.
Is there a way to stop this as it takes me a bit of time to put them back in the right place and becomes a little frustrating.
Any help would be great!
Thanks, Brad.

Hey BSteely and thanks for your reply!
I must say it seems to work better to plug in the cable when the display is on and also wake the computer before plugging in the cable. I still have the shadow under the arrow when doing this. However, when unplugging it doesn't seem to matter. I've now unplugged the external display while the computer is on and then I close the "lid" (display) of the MacBook Pro. Upon wakeup shadow under the cursor is gone and a few days ago the computer just "woke up" to a black screen. I had to force restart.
So, first opening/waking the computer before connecting the display seems to work better, but if I want to use just the external display it's kind of awkward having to first wake, then connect display, USB keyboard etc., then close "lid" and wait for computer to sleep and finally wake the computer again using the USB keyboard. All in all I really think it could work a bit more smoothly, *especially since Apple makes both the hardware and the software.* Well, they don't make the Dell display of course...
Anyone know how well/different all this work when having an Apple Cinema display?

When I connect a second display both displays start to cycle on and off.

I am connecting a second display that works on both my macbook and macbook pro. When I connect it to my imac, both monitors start blinking on and off.
Any ideas?
Thanks

Long story short I solved the problem, and it was totally a model issue. It is the HP w2207, which apparently has a problem with iMac 24 inch, the nvidia graphics card, mini DVi to DVI and 10.4 in particular. You see these two devices, just don't get along very well. The imac tries to auto set the monitor at one resolutions and the monitor tries to auto set itself at another, and they will continue to do this indefinitely. However both when I switched to a VGA cable, which I believe prevents the monitor from auto setting itself, and when I upgraded to 10.5 solved the problem.
Personally I didn't mind the upgrade, as I was planning to do it anyway, and is definitely the better solution as there is noticeable difference in the color between the two cables.
Anyway thanks for the help everyone.

Cannot change display resolution when connected to external display

On my 2.0GHz 13" MacBook, I have no problem with the display resolution when connecting to external display/projector when I am running in Mac OS, everything work perfectly! But things start to get messy when I am running in Windows VISTA 32 (installed within the Boot Camp 2.1). Whenever I connect to any external display/projector via a MiniDisplay-to-VGA cable, the resolutions on both my MacBook LCD and external display/projector drop to 640x480. And i am not able increase the resolution in the Display Settings. Does this mean that I have not installed the latest version of display drivers? Or is it that Apple did not provide the VISTA 32 drivers (in Boot Camp 2.1) that is compatible with the Mini Display port.

Cool!
I'm glad you have it fixed.

No WIFI when connected to External Display

When I connect MBA to a Dell 2405FPW monitor, wifi gets a "connection timeout".
When I disconnect external display, wifi works - all this with the same wifi point.
I took MBA to the apple store, they connected the MBA to their displays and it works. This is very stressful since I cannot take the dell monitor to the apple store - Its where I work.
I also tested the MBA on a newer 24" dell monitor(At work) with same output. My only result was turninng to a less dimension monitor - works fine(again, all with the same wifi point). Is there a limitation when connecting MBA to external monitors - MBA? Again, very frustrating dealing with this issue. My previous MBP had no issues with this dell monitor. Any recommendations will be appreciated.

Alexander - I have a MBA 1.6 HDD and have been experiencing the same problem as you have. I connect via micro DVI to a 23" Apple Cinema Display and have been losing transmission speed or connection altogether with my Airport Extreme.
I have been reading the posts regarding this issue and found a link to this article on maximizing wireless connectivity with an external display and MBA: http://docs.info.apple.com/article.html?artnum=307295.
After reading the article and trying different settings, I found that my Airport was set to channel 11 and if I set it to 6 I stopped having connectivity issues and was able to work without incident. Give it a try - I hope it works for you.

Dashboard and window sizes when connecting to LED display

Hello,
I just bought the LED display yesterday...gotta say thats its beautiful....i have one problem though....when i connected it to my macbook all the window sizes (e.g safari, itunes, dashboard) were too small....I tried modifying them...but now when i disconnect the display the window sizes on the macbook are too big and out of display....the resolution on the laptop is 1280X800 and on the screen its 1920X1200
any way to fix this?
Thanks

My experience is that if you are connected to the larger display and then disconnect without restarting, then you will see the behaviour you are describing.
If you restart the machine after disconnecting, the MB is smart enough to make everything fit within the native (and only available) resolution.
Good luck!

Unable to move applications/documents between spaces--why?

I've noticed this the last couple of times I've used spaces on my _*Macbook Pro:_*
I'll have 4 spaces, each with a different application or document. When I try and move a document or application to a different space, I simply can't. It's as if the applications are frozen in those spaces.
In other words, I can't move applications between spaces. They seem frozen in their spaces.
In both instances, my Macbook Pro is plugged into a Powerpoint projector using the adapter. My Macbook is set to mirror displays so as to project on the screen.
No problems pre-Snow Leopard
Any ideas?

Never mind I just fixed the problem by searching around the community and finding this thread https://discussions.apple.com/thread/4024312
Anyway it was as simple as holding down the application in the dock and just selecting "Options -> Assign to -> None (rather than All Desktops).

Firefox cannot load websites when connect/disconnect from any VPN connection

I am consistently uses OpenVPN and RamsesVPN connectivity. But whenever i switch between the VPN connectivity or connect into any VPN or disconnects existing VPN connectivity. My Firefox Browser is unable to load new webpages/Refresh existing open TABS.
In order to restore, i have to restart my Browser each time, whereas i am not facing this problem with Chrome.
I am running with Windows 7 Enterprise edition, and latest Firefox version.
Is there any method to avoid these restarts ?

Hi, this bug is old, but it has useful info for VPNs
See for reference Bug 702111
And there are built in features on the about:config file that you can tweak the number of connections and allowing pipe lining: [http://support.vpnsecure.me/articles/ssh-tunnelling-proxy-troubleshooting/tweaking-firefox-for-best-performance-security Third party information on these connections]
Other suggestions I have seen are to add bookmarks while logged into either vpn. (For example, bookmark the frequent sites you use in either vpn in separate folders)
In Firebug, when you connect or refresh the page when moving from one VPN to the other, do you see a termination in the connection to the first vpn?

MacBook AIr usb ethernet slow when connected to second switch

Hi,
We have MacBook Airs with 100 Mbps Apple USB ethernet adapters.
We have managed Cisco switches for the LAN.
We experience fast speeds when a USB etherenet/MacBook Air is connected directly to the switch.
However... if we introduce a second switch between the MacBook AIr and the main Cisco switch we experience horiffic slowdowns for some (not all) network activity.
For example, we have IP phones with ethernet passthrough. They work great with iMacs and Thunderbok Macbook Airs. However, if we connect a MacBook AIr/etherenet adpater to the ethernet phone, we expereience a horrific slowdown when using Apple Remote Desktop Manage > Copy items... (and also on connectoins to an in-house database). It's probably 15 - 20x slower than when connected directly to the Cisco switch. Other network operatoins work at expected speeds an the Air.
It's not just connecting to IP phnones that causes this problem. If I use a Netgear 1000/100 switch on the desktop, set up as
MacBok Air USB ethernet > Netgear > Cisco
we have the same horrible slowdown for some network operations.
I purchased a 3rd party USB adpater, but had the same results.
Can anyone shed any light on this issue, please? Is there a setting onn teh CISCO switch that is causing the problem? Any know problmes with USB etherenet on MacBook air.
Many thanks,
b.

Is this a question? A complaint? Nothing any of us can do about that, and this is a well-documented and well-known issue.
It doesn't effect most MBA users who most likely use wireless for most of their transactions, and the times you need to use ethernet, you are right, it will run slower.
Just curious I have a pretty fast 5N wifi network. If I'm setting up a new MB Air from another laptop is it going to be faster through the ethernet adapter or the wifi network?

The iTune Remote App has stopped finding my iTunes library when connected to wifi from my main router, but works fine when connected via second wifi router on the same network (different SSID)

I'm running iTunes Remote App from a couple of iPhone 5's and a first generation iPod Touch. iTunes is running on a PC - Windows 7. My home network runs two Wifi Routers, each with a different SSID. I've had no problems with the Remote app running this set up for the last 8 months but recently the App can only find my iTunes library when the iPhone/iPod is connected via one specific router, when connected to the network via the other router, no iTunes library is found. I'm also running an Apple TV and it's the same as the iTunes Library, only visible via the one SSID.
Everything else seems to work fine when connected via either router, eg Internet on the iPhones (definitely via wifi)
I've tried renewing the lease on the iPhone wifi connection, restarting everything.....several times.....
It used to work fine, this only seems to have been a problem in recent weeks
Any help or advice would be much appreciated
Thanks
Ian

It turned out to be the firewall settings on our router. Her machine was sending traffic that our router interpreted as a DoS attack and blacklisted her Airport's MAC address. That's why it would work fine if she switched to Ethernet.

Wallpaper with the cursor when connected to external display

Hi guys. I recently bought a MacBook 13" unibody polycarbonate white and I had bad luck and cracked the screen and I don't have the money to get it repaired so I decided to buy a mini display to VGA and hook it up to my old dell monitor.
I turned off the computer and plugged the port in and it connects to the monitor but I only see the wallpaper with the cursor and no login screen or anything. I was reading around and found out that I might have to play with the resolution to make the monitor work. Now my delimma is that my LCD screen is cracked so how can I make the monitor work without looking ?

Can you see anything on your MacBook screen? If you can access System Preferences you can drag the window over to the other screen. You have the display set in Extended Desktop mode. In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box.

MacBook Pro's Color LCD "shifts" when connected to external display?

I have a 2010 MacBook Pro with the hi-res anti-glare screen. I just noticed that the internal color LCD "shifts" its colors when I connect it to an external display (a Dell 2408 WFP). If I disconnect the external display, the colors internal color LCD go back to "normal".
I have two images to show what I mean:
This is what it looks like with the external display disconnected i.e. the MacBook Pro on its own: <http://www.flickr.com/photos/vazexqi/4558641163/sizes/l/>
This is what it looks like with the external display connected: <http://www.flickr.com/photos/vazexqi/4559271260/sizes/l/>
The wallpaper is from pixelgirlpresents.com. I didn't notice this problem before with my older 2006 Core Duo MacBook Pro (OS X 10.5.7).
My guess is that with the external display connected, somehow the color LCD decides to use the external display's profile as well (instead of its own).
Any ideas on why this is happening? And, more importantly, any ideas on how to fix this?
Thanks.
Nick

@Stefan: Thanks for the tip. I tried it but unfortunately it didn't solve the issue. The color is still off.
Incidentally, just out of curiosity, I tried these two things:
1) I tried the "Mirror Displays" option in the Displays Preference Pane. With this option enabled, both displays actually displayed the right colors (right with respect to how each display is calibrated).
2) I opened the same desktop wallpaper in Preview. Whenever I drag the Preview window so that it spans/crosses both displays (external and Color LCD), there is a light flicker in the wallpaper in the Preview Window. For that brief moment, I can see that the color is right before it changes to the shifted color on the Color LCD.
I found a possibly related thread on a different forum <http://arstechnica.com/civis/viewtopic.php?f=19&t=37841>. That doesn't seem to help when both displays are connected.
Now, I am just wondering if this is considered normal - wonky color shifts between the desktop/different windows happen when you have two displays connected....
Nick
PS: Note that I am not a graphics designer so my definition of right/wrong is just based on my experience looking at the wallpaper and remembering what it should look like on each display by itself.

MacBook Pro Retina hangs on startup when connected to Thunderbolt Display

I have a MacBook Pro Retina and it's basically almost always connected to my Thunderbolt Display. Each time I start it up, I open the MacBook just slightly and press the power button - and almost instantly the MacBook goes ontop the startup Login screen and at this point is where I close the MacBook and login through the Thunderbolt Display.
Since last night for the very first time - My MacBook Pro hangs on a white screen and takes a long time before going to the Login screen. I've tried to swith the Thunderbolt Display off from the mains - I've also tried to boot up my MacBook on it's own without it being connected to the Thunderbold Display and all is fine (it almost immediatelly shows the Apple logo and then staright onto the Login screen then BUT as explained, as soon as the MacBook is connected to the Thunderbolt Display and I power it up - it hangs on a white screen for about 30 - 60 seconds before it goes to the login screen!
I have no idea how from one day to the next this could happen? Perhaps it's some Apple updates I've made recently which I cant really recall because I usually just update software when required to do so.
Hoping anyone can help.

Hello FunkTunes,
I recommend this section of the article Apple computers: Troubleshooting issues with video on internal or external displays found here http://support.apple.com/kb/ht1573.
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
All the best,
Sterling

Squeeking sound when connecting but no display

My ipod non 1G makes squeeking sound when connecting to my computer but no display and no functionality. When disconnecting from computer he is completely dead. Any idea which component is causing that so I can repair it?

Yes it is.
I've also tried putting it into different USB ports as well as 3.0 and 2.0.
And im sure that the screen works because it works fine with my MacBook Pro, so im thinking that i need some sort of driver... Not sure though...
