Hi, firetiger.... i have the EXACT same problem!!! i have the same Macbook aluminum unibody screen also. I have no idea how to fix it. I'm also out of warranty and i've tried everything... resetting the pram, trying to restart in safe mode, trying to boot from a cd... .NOTHING WORKS!!! i can still control brightness itself but ive never tried attaching to an external monitor. I know everything is loaded correctly... i just don't know whats wrong. If you have any ideas.. please let me know. Also, I think apple will fix the macbook pros with a similar issue for free http://support.apple.com/kb/TS2377 but i know this doesnt apply for me. hopefully they work something out because I really love that computer!!!

You could try wiping the hard drive and reinstalling the OS and all your programs.
Did you install any programs yesterday?
If not it may be best to take it to an Apple care center and have it checked out. Take it in while it is asleep so you ccan show then what is happening.

To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2a: On 10.5: Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
2b: On 10.6: Those receipts may be found as follows: In the Finder use the Go menu and select Go To Folder. In the resulting window type
/var/db/receipts/
2c: on 10.7 they're at
/private/var/db/receipts
A Finder Window will open at that location and you can remove the iPhoto pkg files.
3. Re-install.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
If you purchased it on the App Store you can find it in your Purchases List.

Iphone 4 will not start up....the apple icon comes on and then goes off and then comes on and then goes off continuously....any ideas?

1. Try doing a hard reset:
Press and hold both the Home button and the Sleep/wake button simultaneously for about 15 seconds and release when the Apple logo appears.
2. If that doesn't solve it, use: http://support.apple.com/kb/HT1808
Using this article will erase everything on the device, so make sure you have a backup!
If you get specific error messages/codes in iTunes when updating/restoring, check this: http://support.apple.com/kb/ts3694 for causes and solutions
Good luck

Easy question I'm sure. imac hard full (500gb) mostly from iphoto. no capacity left. what are my options? I've thought of an external drive of 1tb and then a 2nd external drive of 3tb to back up both???? please help.

Those are the options - more space is more space.
Moving the iPhoto Library is simple:
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

Wake from sleep - screen briefly comes on and then goes black

I have a late 2010 mbp 17" model with no issues until last night.
I have my computer plugged in, and when it's not in use I close the display down and the computer enters sleep mode. When waking it from sleep, the screen will briefly come on and then go black. After a few opening and closings of the display, the display will remain on - the number of times opening and closing the display varies before it remains on.
An easier solution I just tried is by unplugging the computer from power - the display comes right on and remains that way.
When the display goes out, the keyboard backlight remains lit.
The only thing I recall that would have any sort of adverse affect on this is the static electricity that I had with this yesterday or the day before. I live in a dry climate and was shocked when I touched the computer the other day. Nothing really bad, but could this be the culprit? Again, I have never had any issues like this before.
Is there a solution to this? Within the energy saver, the settings (except the amount of time before the computer/display goes to sleep) is identical for both powered and battery sources.
Thank you for any help.

To add, I have tried the following:
Open Terminal
Type the following:
     pmset -g | grep hibernatemode
It should say something like:
     hibernatemode 3
Here's an explanation of the different types of hibernate modes:
0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
5 - This is the same as mode 1, but it’s for those using secure virtual memory (in System Preferences -> Security).
7 - This is the same as mode 3, but it’s for those using secure virtual memory.
To change your sleep mode, use the following command:
     sudo pmset -a hibernatemode 0
(replace 0 with whatever hibernate mode you desire)"
Also - the white light that comes on while in sleep mode on the front right of the computer does not fade in and out like it used to...
Gah, I don't like issues

I open my MacBook Pro lid, the screen comes on momentarily, then goes dark, and I can't do anything

OS X 10.6..08
MacBookPro6.2
I never reboot. I have a lot of windoes open. Every week or two I'll open the lid to get to work and the display comes on then goes off and I can't do anything. The keyboard backlight is on. If I close the lid the white pilot light on the front right edge is on. I have not been able to guess a key combination to get it back. The only thing I found is to press and hold the power key to force a reboot. When it comes back up it usually sends a trouble report.

Inside your Utilites you will see the Console.app. Click on it. Reports will be there.
Yes I have tried a short press of the power button. I've opened and closed and done short presses and waited several minutes for something to happen afer each action.
Since I can't see the screen I can't close/quit applications.
It opens closes, sleeps wakes just fine several times a day, and for days in a row. Then one day it exhibits this bad behavior.
Thanks for asking some questions and offering suggestions!!

When I shut the lid to my computer and then open it again the screen comes on and then goes black and I have to press random keys to make it show again. Does anyone know why this is happening?

When I close my lid to make the computer sleep and I open it back up again when I am ready to use it the screen turns on and then turns black. I have to press random keys to make the screen show again. Any help is greatly appreciated!

First, before you sleep your MBP, make sure you either scroll down the Apple menu to sleep your machine, or do it even more easily by pressing CMD-OPTION - DiskDrive (upper right hand corner of your keyboard). I wouldn't just close your machine to let it sleep.
It's hard to know exactly what's happening, but here are a few pointers.
1. Go to System Preferences/Energy Saver and make sure you've set a sleep time of more than two or three minutes. Your machine may be trying to sleep too early. In the same preferences, set Computer Sleep to more than ten minutes, to make sure you don't get an unintentional sleep.
2. Take a look for third-party applications you might have installed.
Post here with your results!

Firefox will not open at all. After click the hourglass comes up and then goes away and nothing happens at all. Nothing will load past the desktop. I cannot get into firefox at all to enable anything or disable anything.

When i click on the mozilla icon on the desktop the arrow will spin (VISTA) and will then disappear. Mozilla will not enable or even pop up or anything. I am still looking at the desktop and not mozilla. I lick on the icon many times and nothing ever enables, still stuck looking at the desktop and no Internet. Not to bring up your rival, but IE will open half way and then say not responding and will freeze and i must restart the computer every time. I have to use opera now because IE and Mozilla will not enable and Mozilla wont even pop up or enable or anything...just the desktop and no net. ONCE AGAIN MOZILLA WILL NOT ENABLE, SO I CANNOT GO TO TOOLS OR ANYTHING.

I have exactly the same issue. After FF upgraded on its own to version 5, it won't open from start menu, taskbar, desktop icon, or even by pressing firefox.exe in program files directory. It does so by pressing a link at msn messenger, inside Outlook etc.
Disabling all addons, didn't help. Moreover, I can't start FF in safe mode or start profile manager (Start > Run> firefox.exe -ProfileManager).

Macbook Pro Retina (late 2013) and support for two external monitor

Hi,
I have a Macbook Pro Retina 13" (Late 2013) and are looking to buy two DELL U2414 monitors. But after searching the web i´m a little bit confused if my MBPr will actually supports connecting two montors from one single Display port.
I will be using this montors at work where I use my MBPr with Windows7 (Paralllels).
I want to set up these two monitors with extended desktop not mirroring. The reason of using just one DP on my MBPr is that the other one is used by my wired ethernet connection. Will this work under OSX10.9.2 or 10.9.3?. Does my MBPr 13" support DP1.2a MST that is needed for daisy chain multiple monitors?

The hardware supports DP1.2 and MST but unfortunately at present OS X Mavericks does not.

My macbook screen's mesed up. What's wrong?

Vertical lines keep appearing and dancing up and down until the whole thing goes white. When one line appears, that part of the screen will stop changing, so the picture stays the same. More and more lines appear until the whole picture gets messed up. So is it the screen or some connection or what?

ooops, I meant horazontal lines

HT3228 When I try to send an email from my Iphone it will not send and tells me the recepient will not allow relaying. The email will sit in my outbox and then at some point will send. It sometimes takes days. What is wrong with my settings?

When I try to send an email either new, or reply on my phone I receive a notification that recepient will not allow relaying. The email will then sit in my outbox. At some point it will send but it is hardly dependable. What is wrong with my settings?

The collum to the right listed similar problems. The solution appears to be that under smtp outgoing settings the user name and password are listed as optional. I have not plugged in the information and it seems to be working. However from my office it always allowed the relaying. The true test will be when I try to respond later from the road.
Thank you for your help.
