Keyboard Backlight not working Macbook Pro Mountain Lion

Since updating to 10.8.3 it seems my keyboard light has entirely gone out. I have reset the SMC and the PRAM. I do not have File Vault installed. I've tried Pin Tick app and also obviously played around with everything possible in preferences to make it light up...nothing. Any other suggestions? Mid 2010 Macbook Pro.

One more thing to try:
System Preferences > Keyboard > uncheck Adjust keyboard brightness in low light

My new macbook pro (Mountain Lion) will not log into my 1and1 server to connect to my e mail. My snow leopard macbook does not have this problem - Apple support say it is a 1and1 problem! do I have to wait for an update of Mountain Lion?

My new macbook pro (Mountain Lion 10.8.1) will not log into my 1and1 outgoing mail server. ( It will receive mail - but does not send)My old Snow Leopard macbook does not have the same problem ( server settings etc. are identical) . Apple Support say its a 1and1 problem , 1and1 say it is an operating System prob - I have tried changing port numbers.

My eyes just glazed over...Please in the future break down each of your issues with paragraphs separated by two carriage returns. It would be much easier when trying to address your issues.
Go to Apple menu -> System Preferences -> Keyboard and Mouse -> Mouse
And edit your mouse settings to do what you want it to do.
Secondly, this is not the place to vent. If you have a complaint, there is:
http://www.apple.com/feedback/
or http://www.apple.com/contact/
We are just end users here helping other end users.
Third, from my understanding, it would appear you are concerned about the noise the hard drive makes when it falls asleep? Why not put your machine in screen saver mode instead? Apple menu -> System Preferences -> Energy Saver turn off all Energy Saver settings, or set them to run Never.
Fourth, if your machine was purchased just a few days ago, you may still be able to get an exchange from the store, quicker than you can get a repair done. You may want to look into that possibility.
Fifth, it does appear you found the Logic forum. I would persist in asking there how to solve your technical issue with Logic regarding the audio. It may be you don't have to do anything special to the hard drive. Remember audio can be transmitted by wire, avoiding ambient sounds.
Good luck!

Ok...
So I bought my MacBook Pro second hand, and it came with no installation discs, but I got Mountain Lion and had it installed and decided to back it up to a disc in case of this scenario. I followed some instructions to make a bootable disc and used it to install a fresh copy of Mountain Lion back when I first got it.
My problem is that without the boot partition of my MacBook's hard drive it doesn't seem to want to boot the disc.
Since I didn't want to buy a disc and I don't have another MacBook or know anyone near me that does, I decided to download a hackintosh iso and use it along with my other laptop to install iPC 10.5.6....this installed successfully and my hopes were that my MacBook would be able to boot it, so I reinstalled my MacBook's hard drive and to my surprise it booted, although not normally. Since it is hackintosh it has some rewritten boot features so it's not a true OSX, but it is fully functional. Since I finally had OSX booted I figured I was in the clear and would be able to install Mountain Lion from this, but then I found out that you have to have Snow Leopard 10.6.8 or later in order to install Mountain Lion.
Now I'm stuck with a hactintosh version of Lion and still no way to get back to Mountain Lion, is there anything I can do now that I have a functional OSX installation?

How do I install/upgrade iWork 2005 on my new MacBook Pro / Mountain Lion?

I just bought a new MacBook Pro (converted back from Windows) and installed an old version of iWork (2005) I purchased years ago, hoping to upgrade it. It didn't install properly as it only shows a folder in Finder/Apps, with a couple of docs in the folder and doesn't show up as an app for Upgrade. The guy that upgraded my MacBook Pro to Mountain Lion at the Apple Store told me this should work.
1) How do I install iWork 2005 on my MacBook Pro / Mountain Lion?
2) How do I upgrade it without having to purchase a new copy?
Thanks!

You cannot link any version of iWork installed from a retail disk or trial to the Mac App Store.
You install iWork '05 on your new Mac just as you always have, making sure you have the serial number to enter. But the iWork apps are very reasonably priced on the Mac App Store & have come a very long way in 7 years. And now Numbers is available for spreadsheets.

Home sharing does not work with new mountain lion update.

home sharing does not work with new mountain lion update. Does anyone else have the same issue. Updated all computers in my home, deauthorized and reauthorized each computer. turn off home sharing and turned it back on. don't know what else to do..please help...

Our Apple TVs continue to lose connection ever since installing Mountain Lion on the host computer. The only thing that fixes them is to quit and relaunch iTunes, which only works unti the ATV goes to sleep. If a movie is paused for more than a few minutes and the ATV goes to sleep, pressing play again on the remote is greeted with "There are no movies on this computer" or "Turn on Home Sharing."
If we stop a video on one ATV and attempt to resume it in another room, the error begins again. The other ATV can't connect until iTunes is relaunched.
My guess is that it has something to do with the new [annoying] security settings. But I still haven't found a fix other than restarting iTunes everytime we want to watch something from our downloads. Fail.

My sister can't find Pages on her Macbook Pro Mountain Lion, can someone help?

My sister is new to her MacBook Pro Mountain Lion and thinks she may have deleted the Pages program. She's away at college for the first time and needs this program. I've told her to use Finder and search for Pages, or look in her applications, but to no avail. Help?

How did she acquire Pages in the first place?
If it was a purchase from the Mac App Store, all she need to do is launch App Store (from the  menu is easiest), sign in with the Apple ID & password used, click on 'purchases' & click the INSTALL button to the right of Pages in the list.
If it was from a retail DVD she will need the DVD to reinstall.

Problem with Macbook Pro early 2011, webcam not working in any apps and windows 7 or 8 on bootcamp, keyboard backlight not working?

Hi Guys
I recently bought a second hand early 2011 Macbook Pro 15 inch and are having 2 problems. The first is that none of the apps detects my webcam at all, the second is, i have Windows 8 installed on bootcamp but are unable to get the keyboard backlight to work in 7 or 8. The backlight works perfect in os x 10.8.5 though. I need a little bit of help guys.....

Go to Apple Menu / About This Mac. Click on More Info ... next on System Report. In the left hand column, under Hardware, select USB. The right side will show the USB Device Tree. Look through that and check for "Built-in iSight". That is your camera. If it is not listed the camera is not working.
For backlighting, try this: go to System Preferences / Keyboard. Uncheck "Adjust keyboard lighting in low light".

Macbook pro (retina) keyboard backlight not working after Yosemite update

Help,
My keyboard backlight stopped working when I upgraded my Macbook pro (retina) from Mavericks to Yosemite. Nothing in System Preferences -> Keyboard makes a change. This is a feature I use a lot. Any help will be appreciated. Thank you.

Try a SMC reset:

Bluetooth, iSight and Keyboard Backlight not working. Please help!

My Bluetooth stopped working along with my iSight and Keyboard Backlight. I first noticed the weird sign over the bluetooth icon, and it read "Bluetooth not available". I payed no attention to it for a while until I tried to take a picture with Photo Booth and I read "No camera found", for some reason I tried to dim the backlight on the keyboard and a blocked sign appeared under the brightness level, not letting me do anything (Later I was able to use the backlight with the LabTick app). I have tried everything. SMC, PRAM, NVRAM, logging as diferent and new users, booting in safe mode... every solution I have found on the internet has been tested by me. Then I read this about the Hardware Test solution, and surprisingly after performing the Hardware Test no problems were found! So basically my MacBook Pro (mid 2010) is not having any trouble of any sorts with anything. Then why can't I use Bluetooth, iSight or Key backlighting (which only works through LabTick). Given the fact that the hardware test shows no problems I am not comfortable with the idea of taking it to repair. There MUST be something I can actually do to fix these issues.
Does anybody have any idea? I repeat, these are NOT WORKING, NOT FOUND AND NOT AVAILABLE.
- Keyboard Backlight (Only works through LabTick)
- iSight Camera (Not found by any software)
- Bluetooth (No info appears on the system profile, the icon on the menu bar is completely gone)
All three issues happened at the same time, the night before everything was working perfectly fine.
If anyone could help... please!!!
Summary:
MacBook Pro Mid 2010 (http://support.apple.com/kb/SP583) Unibody, can't take out the battery.
Solutions tried:
- Reset SMC: Turning on while holding Shift + Ctrl + Option + Power Button (This makes my MacBook forget about the battery and start up with really loud fan noise, battery icon appears with an X on it, keyboard backlight buttons work, they show brightness level on screen, but the actual light won't work, no bluetooth, no isight)
-Reset PRAM and NVRAM: Turning on while holding Option + CMD + R + P (I have waited for 2 chimes, 3 chimes and 4 chimes at different times, nothing happens. Light, bluetooth and isight are still gone)
-Holding Power Button for 10 seconds, 20 seconds, longer... nothing changes.
-Creating and logging in as new admin user, nothing changes.
-Deleting the bluetooth.plist file and powering off and on again, also rebooting
-Deleting the SystemConfiguration folder, powering off and on again, also rebooting
-Installing "blueutil", didn't help at all, turned it off via terminal with command blueutil off.
-Performing Apple Hardware Test - Shows no erros or problems on any area after one full hour of testing (Performed the extended testing)
-Leaving it powered off overnight
Please anyone help meee!! I can't afford going crazy!
Thank you so much in advance!

Keyboard Backlight not working anymore.....please help.

After installing Boot Camp 2.1, I can't get the keyboard backlight to work anymore. I am in the darkest of dark rooms. Pressing F8 just shows an attempt to turn it on but it has a circle with a line through it.
I am running Windows Vista 32-bit SP1.
Are there drivers I can install manually?
Thanks.

Here is something funny. I rebooted with the room completely dark. When Windows came back, the keyboard was backlit. But, when I turned the lights on, the keyboard stayed backlit. And, even better (or worse), when I rebooted again, the keyboard just stayed backlit even to the point where I was choosing between booting into OS X or Windows. That is crazy! I don't know what is going on anymore.

Late 2011 MacBook Pro (Mountain Lion 10.8.2) backlight keyboard not functioning properly?

I have a late 2011 MacBook Pro running OS X Mountain Lion 10.8.2 and for some reason, the automatic backlight keyboard will not funtion as it should. When I have the "Adjust keyboard brightness in low light" option enabled in settings, and I turn on the lights, my backlight keyboard stays at full brightness. Then, when I turn off the keyboard, then the lights, the keyboard does not turn on! Correct me if I'm wrong, but I am pretty sure that this was a feature in the MBP lines.

Try a SMC reset. Shut down the computer. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. Release all the keys and the power button at the same time. Press the power button to turn on the computer. Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Macbook Pro 17inch late 2011 keyboard backlight not working

Recently near the end of sum me 2014 I only noticed the backlight keyboard not working at all. I have done the following to try and rectify;
1. Reset SMC
2. Rest NVRAM
3. Disconnected battery and the above
4. hardware test online, result showing no issues found.
with all outcomes proving nil. Pressing Fn + F5 or F6 does show the brightness either increasing or decreasing but with no light. I then opened her up and disconnected a cable that was to the LHS of the RAM boards but this only powers the White Sleep LED and not the backlight keyboard on this 17inch model. My next step is to remove the mother board and find the actual cable that does power the backlight LEDs and ensure that it is connected. Similarly around the same time I noticed this with the backlights the fans were running fast. However the weather has gotten cooler and the mbp is not running fans as it was when it was in the warmer months.
Do I have to remove the motherboard and actually make sure that the connector for the backlights hasn't been dislodged?
Anyone out there with a 17inch mbp late 2011 that has had this problem please help.

Thanks Ogelthorpe, I found an excellent video (not in english but it didnt matter) https://www.youtube.com/watch?v=8HNAGodYMNA .
What I found was that the keyboard backlight is intergrated into the black plastic cover that is between the motherboard and the back of the keys/LEDS and its all one piece back to the connector that connects to the motherboard under the LHS fan. I need more details to find out if the LEDS are controlled by a chip or what, but it seems to me that I need to visit an apple store/repairer, however this will be really difficult for me as Im in an isolated location. If there are further tests that I can conduct on my own, I would be grateful. Even if there are tests that Apple themselves conduct to find out what the problem is

Keyboard backlight not working - settings missing on MacBook 2,1??

I have a macbook 2,1 that was given to me by a friend about 6 months ago. It is in perfect condition except some seperation around the edges. So, I took into the Apple store a couple of days ago and they replaced the entire 'inside' of the macbook; meaning screen surround, keyboard and surrounding 'faceplate'. (Excuse the incorrect terminology) I also mentioned to them that the keyboard didn't have any backlighting (at least I have never seen it) and the tech said would also be repaired as a result of the keyboard replacement.
ANYWAY, I am home and the keyboard backlight is still not working. I searched mac help and found the following:
To set keyboard backlighting for a portable computer:
Choose Apple menu > System Preferences, click Keyboard & Mouse, and then click Keyboard.Open the Keyboard pane of Keyboard & Mouse preferences
To enable backlighting, select the “Illuminate keyboard in low light conditions” checkbox.If you want to automatically shut off the backlight when your computer is idle, drag the slider to indicate when to turn it off.
The only thing I saw was an option for bluetooth - n/a, keyboard shortcuts settings to change shortcuts..obviously and the keyboard setting which only gives me the choice to
1. change the key repeat rate
2. change the delay until repeat rate and 3. a box to check/uncheck if I want to use the f1, f2, etc as the standard function keys.
There is also a button at the bottom left corner which says 'modify keys' which I believe is n/a.
I should also probably mention, when searching help, it also said "The light sensors are located in your computer’s speaker grilles, so make sure the grilles are not covered when you use your computer in low light conditions" . I have no speaker grilles (that I can see) but my speakers work. and it says; "IF the keyboard on your computer can be backlighted, you can set it so the keys can be visible in lowlight conditions". I guess the keyword here being IF so maybe this mac isn't supported for that but I think that it is from what the person at the Apple store told me after looking up my serial number.
Just to add, I did search the forum and found close to the same problems but with different types of macs so I thought I would ask. I am still learning the ins and outs of using Mac so I hope I asked the right questions and I'm not over expanding on the question too much.
I am sure there is a simple explanation...maybe?! So if someone could enlighten me, I would be very grateful!!!!
Thank you!!!!
