10.6.2 causes my display to start dark until monitor sleeps. Then it's okay

Ever since I updated to 10.6.2 I'm having startup issues. When it boots up it looks normal but when it should show the desktop all you see is a black screen with a blinking cursor. I can see the desktop if I use desktop sharing with my macbook. I've discovered that once the monitor goes to sleep it will come out of sleep and work fine. I used my time machine backup to go back to 10.6.1 and I do not have the problem so I'm pretty sure it is an issue in 10.6.2. I programmed expose to use one of the corners to put the monitor to sleep so I can wake it up and us it but would really like a better fix. I tried the usual - repair permissions, different screen saver and background. Nothing fixed it.

Hi,
Try resetting the PRAM. http://support.apple.com/kb/HT1379

Macbook slow to start-up and displays unusual start-up screen

Hey everyone,
For the last week or so my Macbook has been behaving strangely when I start it up from sleep: it displays the screen you would normally get after your battery has fully emptied and you have just powered up your computer again (I'm not 100% sure if that makes total sense..it's the screen with the white bars on the bottom that slowly fill up before it takes you to your login screen) This only happens when my Macbook has run out of charge and automatically goes to sleep and then I plug it in and power it up again, which is why I'm concerned because my computer is plugged in when this happens + the battery is fully charged. Also, the computer is very slow to start up and takes about a minute before I can properly log in (the screen freezes, sometimes it goes black for a couple of seconds and then it goes back to normal) and finally the computer seems to be a bit laggy at times and slower than usual. I have already verified my disk and repaired all the errors that came up (using Disk Utility), and this doesn't seem to have fixed the problem.
I am very confused and cannot figure out why this is happening; I've bought my Macbook only a year ago and I always take exceptional care of it. Has anyone else come across this problem before? If anyone could provide any input or help me figure out the cause, I would greatly appreciate it.
Thank you for your help in advance

Linc - Thank you so much for your response, at least I now understand what is causing this problem. I'm wondering if you know of a way to stop the computer from going into safe sleep (i.e turn this feature off) while it is plugged into AC power? This has never happened in the last 12 months that I've owned my Macbook and now I'm confused as to why this suddenly changed.
Thanks again in advance for your help

Dim display when starting

I still wait for an answer regarding this issue. My MBA's display always starts in low brightness (only a bar). What should I do???

Hi,
Since Ambient light sensing is one of the SMCs, resetting SMC may help.

Have you dropped the iPad?
Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

Globe Displays on Start Up

I recently tried to install Leopard on my MacBook; my only option was to Erase and Install and I really didn't want to do that. So I looked in the support section and found this is a common problem. I tried using disk utility while using the leopard install DVD still as my startup disc. It did not work so I did what they said next and quit disc utility and tried start up again from my hard drive. It was taking forever so I just shut down and tried to start up again. Now whenever I try to start up a flashing globe displays on start up for awhile on the blue screen, eventually it will load. I do not know what this means and I would like to figure out why this is happening before I try installing Leopard again. Any advice would be appreciated.

Hi Clay...welcome.
What that means is your MacBook is trying to startup to a network volume that's not even there. When you do have it booted up go to System Preferences->Startup Disk and select the OSX volume not the globe.
I had trouble upgrading to Leopard but I did and Archive & Install (after a few failed attempts at upgrading) and it worked fine. It still keeps your system as it was (basically like an upgrade) so it's pretty painless.

Satellite A100 - black display at start-up

Since two days my Toshiba A100-495 laptop / model-no. PSAA9E-18F047GR / serial-no. Y6065357Q with Windows XP SP3 shows a black display at start-up. There is even no Windows start picture.
The laptop does all the booting, but after finishing and being ready for use, the display is still black. When I am pressing Fn + F5 keys, the desktop appears.
The black screen is only at cold start-up after shut-down, not at awakening from stand-by or pause.

I have connected an external monitor (power ON) to the shut-down notebook, then started the notebook.
There was nothing to see neither on notebook monitor nor on external monitor black screen as before. After the booting was done, the desktop appears after pressing Fn+F5 for about three seconds.
I have not jet tried to change BIOS settings because there is no Toshiba splash screen on start-up. I am afraid I can not see what is going on or what I have to choose after accessing BIOS without display signs.

When links are clicked, they do not fully display the NEW page until the mouse is moved.I know it is a current bug, and appears in no other browsers that I know of.

It was pointed out that my links do not function correctly on Firefox on a Windows platform. When links are clicked, they do not fully display the NEW page until the mouse is moved! I have now observed it for myself on my fathers PC running Windows XP on Firefox.My PC is on Windows7
It is the 5 version of Firefox, so I know it is a current bug, and appears in no other browsers that I know of.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Cinema display won't come back from sleep

I have two apple displays - a 17" studio and a 20" cinema - hooked up to my 1.6 G5 (Tiger, all the updates). Several months ago the 20" started staying black after sleep. I worked around the problem by adding the "detect display" thingy to my menu bar and that would always bring it back up. Then it started going black when the computer wasn't even sleeping. Again, the "detect displays" trick continued to work, though it bothered me that it seemed to be happening with ever greater frequency.
Well lately that trick doesn't work all the time. And then I have to get down on the floor and physically unplug the display cable from the G5 which _usually (but not always) brings the monitor back up.
Since the connectors for the two displays are different, and I have no other computer to connect the display to, I have no way of knowing if it is the display or the computer or a software glitch or what. I live hundreds of miles from anyone who could diagnose this problem for me - has anyone else encountered anything similar?
thanks,
Lucinda

You are using an ACTIVE (powered conversion from Mini DisplayPort, and are having trouble with it.
Your card generates VGA directly, at the proper Voltage levels, and it may be more reliable that the method you are using now.
The VGA signals are on the bar at the end and one pin from the top row of the grid. I suggest you buy a DVI-to-VGA adapter and use it instead of the converter you are using now.

Why doesn't my built in display re-initialize after resuming from sleep mode?

Hi,
I have a MacBook Pro (2.53 GHz Intel Core 2 Duo, 4 GB RAM) which I purchased a few years ago. I always have a secondary display monitor plugged in.
When I bought this system, it came with Snow Leopard and I recently upgraded to Lion. That's when this issue began:
If I physically fold the screen down and put the MacBook to sleep mode that way, often times when I resume my secondary display will return but my primary built in display will not - it just remains black. In some cases this creates a serious problem because my menu bar / dock are still on the main display and so I have no dock.
I notice the problem has not occurred if I put the unit to sleep using the Sleep command... but sometimes I forget.
I am wondering if anyone else is having this type of issue, and if there is a way to solve the issue? Is it possible this is a bug?
Thanks,
Steve

It is definitely not a Leopard bug because it has been happening on every portable Mac I've ever had.
I don't agree. I had no problems at all with my MacBook Pro running Tiger. I initially did an upgrade from Tiger to Leopard and when the problems started I assumed it was a problem with the upgrade. I then completely erased and did a clean install of Leopard. The problem has actually gotten worse since I did the clean re-install.

Just close the screen, wait for it to go back to sleep, then open it again. It will probably be fine.
As I mentioned in my opening post, I've gone through that song and dance more times than I can count. I've closed it, waited for as much as an hour, opened it back up...same problem. I've hard powered it down, closed it, disconnected the AC adapter, removed the battery, opened it, held down the power button for 15 seconds, re-installed the battery, reconnected the AC adapter, pushed the power button, and the display will still be dark. It's sometimes taken as many as 5 or 6 iterations of that process before it will finally reset whatever problem it was having and boot normally with a functioning display.

How can an external drive cause my Internet to slow to a crawl and then fail?

I have two WD My Passport Ultra 1 TB USB 3 new drives. One I'm using for Time Machine and one for CCC (Carbon Copy Cloner). I have been trying to use them with my new MacBook Pro retina 13-inch.
For the last few days I've had weird problems trying to connect them via a USB 3 hub. I though the hub was the problem (because things seemed to be fine until I introduced a hub into the equation) and already returned one.
But now I see the same thing happening even without the hub.
It appears that one drive, when connected to a USB 3 port (it doesn't matter which port), even when it's doing nothing (I erased and and removed the CCC task), causes the Internet to slow to a crawl, and then stop. All connectivity ceases.
The instant I unmount and remove the drive the Internet springs back to normal speeds - over wifi about 110 Mbps.
Disk Utility says there are no problems with the disk. So does WD's only diagnostic utility. And the firmware is up-to-date.
The other disk, running Time Machine, seems to have no issues at all.
I guess I will return this drive. It could be subtly defective in some way. But what way? Why would an external USB 3 drive affect the Internet connectivity?
doug

I came across this post while in search of the answer to the very same question only I am experiencing this problem when connecting to a USB 3.0 hub and nothing else. The resuling slowdown in my internet speed leaves me hanging intermittently between screens in Safari, sometimes indefinitely. When I remove the USB cable, normal speeds resume. Activity Monitor shows no undue load on the CPU. I did not notice this problem until just recently. Could this have something to do with the recent OSX patch.
BTW: I am running a 2012 15" MacBook Pro with Retina display.
Anybody have a clue as to what might be going on here?

Boot Camp refuses to display on more than one monitor at a time

Hello all,
I just recently purchased a late 2014 Mac Mini and have since installed Windows 8.1 on it via Boot Camp. While using two monitors (one attached via mini-display-port-to-DVI and the other attached via HDMI-to-DVI) they both function as expected when I am running Yosemite. However, when I boot into Windows, at first it will display the Windows logo on the MDP-to-DVI monitor (I'll refer to this as my primary monitor, and the HDMI-to-DVI as my secondary), but once it finishes booting the primary monitor goes to sleep, and the login screen is displayed on the secondary monitor. No matter what I do I cannot get it to recognize both monitors at the same time. I've verified that my graphics driver is up to date (Intel Iris 5100) and have even tried using previous versions of the driver but with the same result. The interesting part is that once I am logged in to Windows, if I unplug both monitors and then plug in only the primary monitor, it will display fine. As soon as I attempt to add the secondary monitor however, the primary shuts off and the OS is displayed only on the secondary. I have also attempted to get Windows to detect the other monitor using the display preferences but it refuses to find anything.
I've spent quite a few hours already researching this and tried several "solutions." Hoping someone out there is experiencing something similar, or perhaps has some insight on what I could investigate next.
Thanks!

I use iWebSites to manage multiple sites.. It lets me create multiple sites and multiple domain files.
If you have multiple sites in one domain file here's the workflow I used to split them into individual site files with iWebSites. Be sure to make a backup copy of your original Domain.sites files before starting the splitting process.
This lets me edit several sites and only republish the one I want.

Not detecting external display after waking up MBP from sleep mode

I am a recent owner of a MBP and enjoying it. However, one problem that I can't seem to find a solution to is the external display problem after sleep mode.
When I first boot up the Mac and plug in my Dell external monitor via the mini adapter, there is no problem with detection or display. However, every time I put the MBP in sleep mode and then wake it up again, the external monitor does not "wake" up and my MBP only displays my normal screen on the Mac.
I tried to 'Detect Displays' to no avail and the only solution is unplugging the mini connection and plugging it back into the MBP for the MBP to re-detect the external monitor.
Although this is a quick fix in itself, I do not want to wear out the mini port by doing this every timeI come out of sleep mode. Any solutions so that the external monitor will detect the MBP waking up from sleep and display properly? Thanks!

And same problem here.
Using a MBP 2.66 i7 with a Dell 3008WFP that's connected to the MBP through DisplayPort. It works some of the time but once in a while (only been using the new MBP for a couple of days now) the monitor won't come out of sleep mode. Turning it off/on causes OS X to completely ignore the monitor. I was able to get this setup to work again by pressing 'Detect Displays' in the System Preferences pane but most of the times that doesn't help. The only sure way to get the monitor working again is by booting into Windows through Bootcamp, Windows is able to use the monitor, if I reboot after that OS X sees the monitor again.
Also saw a magenta line/stripe on the left side of my monitor and the monitor sometimes makes a buzzing sound when connected to the MBP through DisplayPort. That's what you get by using bleeding edge tech I guess :\ Only alternative is buying the mini-DP to dual-DVI connector but paying $99 just to be able to use an external monitor is rather insane. Besides that lots of users are having problems with this adapter.

27" iMac Powers Up - Black Display - Able To Use External Monitor

I have a strange problem, but I believe it's a software problem and maybe could get some help here before lugging it over to the apple store for the second time in 3 months.
- Today when I turned on my 2010 27" iMac it booted up, gave me the start up sound, my external hard drive turned on, fans were going, but the monitor remained off which never happens. The night before I hadn't done anything out of the ordinary like changing settings or installing anything.
- I tried turning up the brightness on the keyboard and that didn't work.
- I shined a flashlight into the screen to see if I could see a faint desktop as if the backlight had gone out, but saw nothing.
- I turned on my external Acer monitor and to my surprise my entire desktop was on that external monitor which I've never seen happen. It's almost like the computer knew the screen was dead and shifted everything over onto that monitor.
HERE'S WHERE IT GETS WEIRD....
- I put the computer to sleep. When I went to awake it from sleep I turned on the external monitor and to my surpise the iMac screen turned on as well, but my desktop was still located on the external monitor. It remains on. It doesn't flicker or turn off after 10 minutes, it remains on.
- I turned off the computer and did an SMC restart which I know is mostly BS for any of the other times I've had problems with the iMac. I figured it would not work and it didn't.
- I can get the iMac screen to come on, but ONLY after it wakes up from sleep, but it's still situating everything on the external monitor. It's as if the iMac is treating it's own screen as an external monitor.
So it's not that my graphics card is dead or my backlight burned out. It's just a matter of telling the computer to turn on the display.
If anyone can help me out I would greatly appreciate it!
- Joe

Tried to Safe Boot, didn't work.
Did one PRAM reset it didn't work. I'll try your suggestion of 3 in a row and see if that works.
I have a temporary solution on how to get the iMac display to work after freak luck:
1) Turn the computer on from being shut down. iMac display is dead. Ext. monitor works with my desktop on it.
2) Put the computer to sleep.
3) Wake the computer up from sleep, but make sure the external monitor is turned off. The iMac's monitor turns on, but the iMacs monitor is treated as an external monitor with nothing on it. I can only slide things over from the external monitor onto the iMac screen.
4) Restart the computer
5) Desktop and everything goes back and gets situated on the iMac display.
I can put it to sleep, but once I shut it down I have to start all over again. At this point my guess is a boot up issue. Because after the iMac screen does turn on from sleep and I restart it everything works fine. It's just getting the screen to come on when it boots up from shut down is the problem.
I will most likely be taking the iMac to the Apple Store. In some misplaced, weird way I get a kick out of it because everytime I bring a problem to them, they've never seen such a problem before, so with my luck they've probably never seen this before.
Thanks again for your help BDAqua!
