OS X :: Desktop Is Empty And Not Working After Using External Display?
Mar 4, 2010
(Not sure whether this is software or hardware related)
I did a powerpoint presentation using my MBP (late 2008, OSX 10.6.2 updated yesterday) and a Mini DisplayPort to VGA Adapter. Afterwards, I unplugged the projector, then the adapter and closed the screen without looking.
When I opened the screen, surprise!:
- desktop is empty: background image is visible, but all files & folders are gone
- all running applications are still functioning properly
- clicking on the desktop or dragging a file to the desktop does nothing
- content of desktop is accessible through Finder
- there are no other usernames in the HD>Users folder
I have not tried a reboot, because I heard of similar symptoms (without the mini DisplayPort) being related to username issues and people loosing all their data as a result.

is there seems to be a major bug in the DVI out drivers, so if you connect your new MacBook or MBP to an external Monitor (Apple Cinema or other make) and then your Mac goes to sleep , you cannot 'wake' the external monitor again - either it stays black or worse you get a sort of snowy, out of signal TV look! You need to unplug your monitor, , then when your Mac is awake, re-plug in the external screen. Report this to Apple guys and post anything you know on it here - sooner they send out a patch to fix it the quicker can get back to normal work!

I have a macbook pro from fall of 2007. So far it has worked perfectly and I've used it with an LG full hd LCD for about 1,5 years. I use a regular DVI - HDMI cable.About a month back it suddenly stopped working. The TV just tells me "No signal".I didn't change any settings or anything. The computer still recognizes when something is plugged in as the screen flicks blue and the displays icon in the menu bar lists the TV with correct model and resolution. And if I have spaces turned on it changes from 4 to 8 "screens".
I have tried everything from rebooting the computer to resetting P-RAM.
I got a new cable, no difference. However when I tried the TV with my friends MBP, it worked. So the problem is definetly in my computer, not in the TV or cable.My OS X is Version 10.5.8 Leopard.

I have a mid-2009 Macbook Pro running Lion 10.7.4. Since I upgraded to Lion the external display stopped working altogether. After connecting adapter to laptop the screen on the laptop goes blue for a moment and then returns to normal. However, the external display is never detected.
I searched in forums before sending this message, but most problems I found are related with some glitches of the screen and they seem to be getting some image in the external monitor. In my case... it simply stopped working at all.

So I have a rather frustrating issue. After installing SwitchResX and now uninstalling it reseting to factory settings I have been left with a pain in the backside.
I have a 20" iMac (1680x1050) and a secondary monitor (1280x1024) and now I and firstly, stuck In some kind of mirror displays mode, even though it is not enabled in system preferences. The wallpapers, resolutions and general screen contents is different except it keep mirroring the mouse movement from my iMac screen.
Secondly, in system preferences, under the Arrange tab, there are now displays in the box, I have an empty box meaning I cannot arrange my displays.

I have a 15" unibody MBP bought in Nov '08.
Had been using the Mini Displayport > DVI adapter just fine with both HDTV and Dell monitor, BUT then all output has stopped completely!
No monitor is detected by the laptop (although the display does blink blue, as if it had detected it), tried different cables, different displays, using the Displayport firmware update, speaking to Apple, deleting the com.apple..plist files, etc
Edit: it also doesn't work in XP on Bootcamp

I have a MacBook Pro 13 for portability to my classes at the university and a Dell 2209WA as an external monitor. One of the few good IPS monitors I could find around for cheap.
The monitor works fine in mirror mode with the MacBook Pro, but as an external display only it does not work. It attempts to wake up and then you see power savings mode again and the screen goes black as if there was no connection. Not sure what exactly the problem here is. Drivers?
The monitor works great with a Mac Mini I have and it works great in mirror but not in external display mode(the lid of the MacBook Pro closed). Anybody know of this issue? The cable is good and the MacBook Pro is not that old(a few weeks).

Many are having issues with font smoothing not working correctly on external displays with SL 10.6.
I researched this issue and found this blog posting:
URL
the blog itself discusses the issue, and the fix is found in the comments.
Basically, for now the fix is to open Terminal App and enter:
"defaults -currentHost write -globalDomain AppleFontSmoothing -int 2″
without the quotes, and hit return.
a log out or restart might be required.
this fix seems to stick even after re-boots and shut-downs.

I have no idea why this happened but now when I open Finder, my desktop, documents, applications and everything else don't show the files I know are there. I also had several files on my desktop that are no longer showing. This is really annoying because I can't access my documents and downloads which I really need to get to right now. I can't think of anything I did to have triggered this but its been like this for at least a few days. I have a Macbook Pro and Lion.Â

I use MS Word on a Mac. In documents, sometimes a .doc file sent with a logo image above text will display the text, but the logo displays only as a border around an empty box. Yet when I send it to anyone else, the logo I can't see appears in the file for them. In some .doc files, I will be able to see different logo images fine. But about half the time, logo images will only display as an empty box.

I have an iMac Core 2 Duo running Snow Leopard V10.6.3 with 4 GB RAM... I've seen the threads regarding the inability to "Empty Trash" and the error code. When I open the Trash window, it is empty. When I place a single item into Trash, there is one item seen in the window. When I Empty Trash, there are then six items being deleted. If I place three items into Trash, then eight items are deleted... etc., etc. What are those weird ghostly five items??

I have 2011 MacBook air and I tried to empty the trash, and only one file wouldn't delete because 'the file is still in use', but the application was turned off. So then I went to finder and clicked secure empty trash, which then proceeded in emptying, but it stayed that way for a long time so I clicked close. Then, it did seem to close, but then didn't and was stuck in deleting.
At that point the Air's fans began to crank up full speed and became extremely hot. I tried to turn off but didn't work so I just put it to sleep at the moment. I'm new with Mac ( in fact this is my first Mac) so I had no clue what to do. In windows I just do ctrl+alt+delete but what should I do with Mac to close the frozen command (in this case secure empty trash). I got scared bc of the fans and the heat. What should I do?

For some times now I have problems with finder. First I thought it was a problem accessing the network but I also have the problem with the local folders!!Â
After logging to my account, it works well for some times and then suddenly (may be after accessing machine on my network - Synology NAS) finder begin to show all folders as they are empty!!!Â
The funny thing is that if for instance I do a "file/open" within an app or do an attachment and so access a "windows like finder" it works!!
But if I use the finder ... folders are empty (shown as ...).Â
The only thing to get everything back is to restart the computer (and many times I have to hard stop the machine as the finder is not working anymore and my mac mini don't want to restart. I keep the desktop background and nothing happened!!Â
The strange thing is that it seems I don't have the problem on my MacBook Pro!! The mac mini was a clean install!Â

How long should it take to reformat an empty external hard drive? It's a GForce MegaDisk two terabyte hard drive and it's been going for about 11 hours with no sign of stoping.
Shouldn't it be pretty quick, since the hard drive is empty?

I have a large trash file---600 GB---on a WD external drive that I'd like to empty to recover space for backups. I don't know how to do it. I don't have a clue where to start?Â
My understanding is that with the .Trashes folder selected in Finder, if I issue the empty trash command what gets emptied is the trash on my computer. How do I empty the .Trashes folder on the external drive?Â

I am running Aperture 3.5.1 in current version of Mavericks on a MAcBook Pro. I am trying to use PSE 12 as an external editor to resize, merge and some other stuff I want to do prior to printing on an Epson 3880.Â
When I try to send a file to PSE by Photos>Edit with PSE 12, an empty window opens in PSE. There is nothing in the Photo Bin. What am I doing wrong or is this not possible to do without exporting a TIFF to my desktop, etc.? I am checking PSE out with their 30 day demo version, if this makes any difference.Â

My external display (HP w2207) seems to conflict with my MacBook Pro (15 inch Retina display, early 2013) since I upgraded MacBook OS to 10.9.4.The external display works at initial boot of Mac but does not work after OS sleeps and I attempt to awaken, and while the external display is not waking, the Retina display flashes through different screen views, which only partially reflect my normal screen, or do not reflect my normal screen at all.Â

I have a folder which I deleted from my external hard drive. Whenever I empty Trash, I get the insufficient privileges error. The folder is empty.
I've tried emptying the trash, securely emptying the trash and used these Unix commands in Terminal too:
rm -rf .Trashes
rm -rf [directory]
sudo rm -rf [directory]

I did a disk repair and verify disk on my external hard drive. When they were done, it created a folder called "lost+found". I deleted it and it went to the trash. Now I can't delete it. I tried the option key, using terminal and secure empty. None worked. When I unplug the external drive, the trash is empty. I connected to another mac and it appeared in the trash there and I still can't delete it. I also tired using disk utility to delete free space and that didn't work. I called apple and they stated to format the drive but I don't have enough storage anywhere else to copy the data.

For the past few months i have been using an external display hooked up to my 12" powerbook g4. I have had it on a dual display mode so no mirroring. Recently i would open the laptop lid waking it from being in sleep mode and my internal display will not turn on. The apply system profiler does not even recognize that the internal display exists. My external display works fine and has always been set as the main display. If i go to detect displays nothign happens. I have tried restarting the computer, instering system disks, unplugging the external and nothing has worked. I simply cannot get my internal screen to fire back up. When i used to unplug my external display the internal display would switch back to being the main display and everything would be fine. Now i cannot get the internal display to function whatsoever. Please try and help me as a need this laptop working and i will be ordering a mac pro soon for use with my external display.

Just wondering if anyone could help me figure this out.
I have my 40" flat screen plugged into my imac via VGA cable to mirror the image.
I'm just trying to have the imac display sleep while I play a movie full screen through the external TV.
I've tried two different ways but both have failed.
1-I set up a hot corner in the imac to sleep display but this results in both the display and the TV sleeping.
2-I just set the power settings to sleep after 1 minute. This works but then If a movie is playing the computer won't go to sleep.

I have a question about using dual displays with my new macbook. The basic issue is this:
1: plug in second display and setup dual monitor support to use the external hi-res display and the macbook's display (no problem here).
2: drag windows to the external display and resize to use (no problems here either).
3. Power down and disconnect the external display.
4. Start up the macbook without the external display and try and open up a program that I was using previously on the external display. The problem is that it is resized and positioned for the external display and is now off the screen of my macbook display and I can't directly get to the title bar to move it or the resize corner to resize it.

I just purchased a 23" monitor to replace my iMacs 17" display (since it has a nasty crack in one of the corners). I hooked it up fine and all, but the displays are linked, allowing me to hover the mouse to the iMac's display which I find annoying most of the time.
Is there a way to make the iMac display zone out and just use the external by itself?
