MacBook Pro :: Black Screen With Cursor For 5-10 Seconds When Trying To Wake Immediately After Display Sleep

Jun 23, 2014

I've noticed that when my rMBP (late 2013, Mavericks) turns off the display automatically while on battery (as configured via Energy Saver) and I try to wake it immediately, I get a black screen with the cursor, rather than my password/unlock screen.  It remains a black screen, with the cursor moveable, for 5-10 seconds or so, and then the password/unlock screen will appear as usual. 

This does not happen if:I don't try to wake the display/computer immediately after automatic display sleep (e.g., I wait 5-10 seconds and it's fine)I turn off the display using a hot corner and immediately wake the displayI put the computer to sleep by closing the lid and immediately wake it by opening the lidI select Sleep from the System/Apple menu and immediately wake it by pressing a key or clicking on the trackpad 

Why automatic display sleep is causing this temporary black screen?  I currently get around it by setting the time for automatic display sleep while on battery to 10 minutes instead of the default 3 minutes to minimize the chances of needing to immediately wake the screen.  I'd like to keep it at 3 minutes if possible to maximize energy savings, but the temporary black screen is really annoying if I didn't really want display sleep and consequently have to wake immediately.

OS X V10.5 Leopard :: IMac Screen Went Black - Starts Up With Black Display

May 24, 2012

I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?

OS X :: Unable To Show 10.6 Install On External Monitor / Grey Box On External Display With Black Bar

Feb 27, 2009

I have a Macbook Pro 2.16 Core Duo, and I'm wanting to install 10.6, but about a year ago, I cracked my screen to the point that I cannot make anything out on it, and haven't replaced it. Instead, I have just been using it in clamshell mode, which has worked out fine so far. My problem is that I cannot get the 10.6 install to show up on my external monitor.

I searched around, and could only find one other similar thread that just ended with the author putting it in clamshell and having it work fine. When I boot to the install and close the screen, I just get a grey box on my external display with a black bar on either side of it. I can't seem to find any other resources, so I'm not entirely sure what to do at this point. Any help would be greatly appreciated.

IMac :: Shows Black Screen - Booting With Windows Partition

Nov 22, 2010

Just installed Windows XP using bootcamp and usually no problems switching between operation systems. Recently started using an USB modem for my wireless internet connection. Internet works on both Mac and windows through the modem. Now the problem is whenever I restart or switch on my computer, it shows a black screen if I choose windows partition to boot. No problem if I start through mac partition. If I unplug the USB modem, everything goes fine and I have to plug the modem after starting windows. Is there any solution so that I can permanently plugin the USB modem and avoid booting problem?

IMac :: Secondary Monitor Not Working - Only Shows Black Screen

Jun 10, 2010

24" iMac running 10.6.3 and having some issues all of the sudden with my secondary monitor. It detects the display and the monitor comes out of standby, but only shows a black screen. Tried it with another monitor to see if that was the issue but it's not. Seems as if the iMac is sending bad video signal out... Couldn't find anything similar on a quick google search so I thought I'd try here to see if anyone had any similar problems.

IMac (Intel) :: Can External Display Be Rotated Into Portrait Mode

Nov 30, 2014

I was told that the new 5k imac can support one external 4k display via thunderbolt, but the 5k imac cannot itself be rotated into portrait mode (on a vesa mount for example). If I connect an external 4k display via thunderbolt to the new 5k imac, can the external display be rotated into portrait mode so I can have 3840 pixels vertically on the 4k display?

MacBook Pro :: (OS X 10.9.3) External LG Flatron Display Remains Black

Jun 22, 2014

I'm trying to connect my rMBP13 (OS X 10.9.3) received a couple of weeks ago to my desk display (LG Flatron W2486L) through apple's DVI-mini display port adapter.

Here is the results:

The MBP freezes a couple of seconds (I guess normal) after plugging in the mini display connector in one of the thunderbolt ports, but nothing happen on the external display (no signal).

The MBP sees the display: from "system preferences>displays" I see the MBP sees the external display and recognises the model "W2486"; but it seems to me that the display doesn't see the MBP... 

I've tried to restart the MBP, but with the same result. 

(I've ben using the display through the DVI port with my old PC, so it works).

MacBook :: Finding An External Display That Matches My Black MacBook Display

Mar 2, 2009

As the title states. I am looking for an external display that matches the display on my black MacBook. I want one with the same gloss finish as my MacBook, this way I can calibrate both screens to look the same. That way when I switch screens it doesn't look different.

Anyone know of a screen that looks identical to the (previous generation) MacBook? I was thinking of getting a Samsung T240 but it has a different finish. How are ASUS screens? Any screens out there that have the same gloss finish?

MacBook Pro :: Recognizes External Monitor But Only Display Black Screen

May 11, 2012

I have a early 2011 MacBook Pro 13" running the latest version of Lion.I have been using my MacBook with an external monitor since I brought it in 2011 and have had no problems with connecting it to my external monitor. Connected via mini display port DVI adapter and a DVI cable to a Philips monitor.

Two days ago when I plugged the MacBook back in to the monitor I connected and but now only displays a black screen, I can move the mouse off the MacBook screen and over to the external monitor and back but it is not displayed on the monitor.I have tried connecting other devices to the monitor and they work fine.

Hardware :: Black Bars On Samsung XL2370 External Display With MBP 15"

Jan 14, 2010

I have a MacBook Pro 15" and my father has 17", both 2007 model.

I bought a new Samsung XL2370 external monitor (1920 x 1080) for my notebook. When I connect it to the 17" model, it works fine and gives me the full picture.

However, when I connect it to my 15" MBP, even at 1920 x 1080, the display gets cropped on two sides with black bars.

If I change the resolution to 1680 x 1050, then the whole screen is filled. But if I put it to 1920 x 1080, this happens.

MacBook :: Unibody Display - Connected To External Monitor - Black Screen

May 7, 2010

Well my unibody macbook display decided to screw up last night, it was working fine last night no problem. Connected to a external monitor. I fell asleep last night with front row left on, obviously it went to sleep and then I woke up and the screen was black. Now the LED lights are working, my external display is also working. The display settings recognize a screen being present (when I click detect displays and gather windows - 2 windows appear). Ive reset PRAM, SMC, reseated the RAM, control+shift+eject (which just made the screen flicker a little after turning it back on) and Im out of ideas. Its out of warranty and about about 18months old.

Intel Mac :: Thunderbolt With Mini Display Port Shows Monitor As Generic VGA

Mar 23, 2012

With my 'old' Intel iMac using a Display Port adapter, my 24" LG Monitor would be detected correctly and worked first time.With my new 2011 iMac 27 using a genuine Apple mini DisplayPort adapter plugged into the Thunderbolt port, this same monitor now shows up as a generic VGA monitor and the range of resolutions is severely reduced - basically it looks terrible.I've tried disconnecting the cable, reconnecting, using the second Thunderbolt, changing resolutions, detecting displays, showing displays in the menu bar. All with no success.

IMac (Intel) :: No Mouse Cursor In Airplay?

Jun 20, 2014

I have a few accounts on my Mac (Mavericks) that I use to train, operating my Mac with Airplay mirroring for demonstration.  While in my primary account, Airplay (AppleTV3) works fine.  Until recently it also worked fine while in my other accounts (all Admins). 

About a month ago, Airplay with the secondary accounts no longer shows the mouse cursor.  I can see the effects of the mouse (Dock magnifies, apps still open, etc.), but I can't see the actual cursor moving around the screen.  My primary account continues to show the cursor during Airplay. 

I created a new user account (Admin), and the new user account also is missing the cursor during Airplay.  Updated all software, restored the AppleTV.

IMac :: Black Screen Display When Wake Up From Sleep

Dec 21, 2010

For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired. So, often it wakes up normally and functions fine, well, not really. It is seemingly very slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think. So It's just a lot slower in general than before.

IMac (Intel) :: Cursor Disappears (invisible) After Exiting TDM?

Sep 13, 2014

I've recently purchased a 0.5m thunderbolt cable to connect my Macbook pro to my 27" iMac. All is fine until I exit Target Display Mode (apple F2). At that point the cursor disappears. Very annoyingly, I can just about trace it's whereabouts via the various cues on web browser windows, and through trial and error navigate to the apple menu and restart, whereupon it's all back to normal. How I can prevent it from happening?

IMac :: How To Keep Display Sleeping While Keeping External Display Active?

Jan 23, 2008

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.

MacBook Pro :: 13" Target Display To IMac - Black Screen?

Apr 26, 2012

I have a MacBook Pro (13'', Early 2011) & iMac (21.5", Mid 2011) using a Thunderbolt Cable to Target Display. Everything was working find and I could Command F2 to Target Display as expected.However, about a week about this stopped working. Now when I try to Target Display the iMac goes to a Black screen (like it's switching to Target Display) and the MacBook Pro does nothing. The iMac will be at the Black screen until I Command F2 again (or disconnect the Thunderbolt Cable), then the iMac goes back to the normal display. I have tried another Thunderbolt cable with no luck. I have perform all software updates on both machines (now both running 10.7.3) and fixed Disk Permissions. I have also found that restarting my MacBook Pro allows this to function as excepected (Command F2, Blue Flashing Screen, Target Display on the iMac). However, this is not an ideal situation since having to restart my computer is time consuming.

Hardware :: Disable IMac Display/use External Display Only?

Jan 13, 2010

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?

IMac (Intel) :: Folder Icon Is Blocked With Mouse Cursor?

Aug 22, 2014

My colleague reported me something a bit strange a creasy. They told me that the icon folder is following the cursor mouse. (It's not a joke) . I just experienced this right now, and I am going to explain step by step, what I did. 

I opened Finder

I selected a folder to move it into the Favorite section (in order to access it quickly via the favorite bar)

I placed it between Desktop and Document.

While I move that folder, the folder icon appear close to the mouse cursor. This is normal

BUT when I released my button mouse in order to create the folder favorite, (between Desktop and Documents), the folder icon remind on the cursour mouse, and follow it. 

Nothing freeze, I can mouve the mouse but it do not react to a click. 

To "remove" the folder icon, I have to relauch the Finder (cmdt+shift+esc), or some time, it desappear after 3-4 minute.

When the icon is remove, the mouse is not working perfectly for a moment. 

We have this problem while we mouve a pdf, or a .doc file.

My colleague work on iMac 10.9.4.

This problem happen while we want to create a favoris to a local folder or to a remote folder. 

4/6 collabrators have this problem and there are all in the same office.

The particularity, they have all a wireless mouse, but I do not think the mouse devise cause this problem..
