Re: 3rd party gaming keyboard backlight button?in response to cameraman_matt
For @camerman_mat and others:
I just bought the CM Storm Devastator keyboard yesterday, and I think its stupid that they don't have a mac solution for setting the keyboard backlight. I am in the process of writting a simple GUI application for OSX based on HID LED Test Tool to set the keyboard backlight status. I will post it up when its done if anyone wants to give it a shot. I think it will help most people. In the meantime, below I have sumed up the steps I followed to get this working for me. All credit goes to above posters.
Instructions:
Download https://github.com/darcyliu/CocoaSampleCode/raw/master/HID_LED_test_tool/build/R elease/HID%20LED%20test%20tool
Rename the file to : "HID" or something simple for now
Go to the directory you downloaded the file using terminal : Ex) cd ~/Downloads/
In terminal type: ./HID
If everything works, you should see your keyboard cycle through backlight states. Once it is lit, press ctrl+C to end the program. Everytime you want to change the keyboard backlight status run ./HID and press ctrl+C when you want it to stay at its current state.
Note:
If ./HID fails to run, make sure you change the permissions on the HID file to exectuable.
In terminal: chmod 777 HID then re run step 4
I feel like I followed this guys exact way and order but it still didnt turn the backlight on. I even tried downloading controller mate and doing it that way but I still couldnt get it. If someone could just walk through it with me again I'd greatly appreciate it.

Hey!
I know that this posting is already a bit older but i recently bought a Devastator keyboard too
I managed to get the LEDs working!
Here are the steps:
1. Go to :
https://developer.apple.com/library/mac/samplecode/HID_LED_test_tool/Introductio n/Intro.html
2. Download the File
3. Make sure you have Xcode on your Mac, if not download it via App Store.
4. Open the Project File (HID LED test tool.xcodeproj) with Xcode
5. Go to Product and select Run or just push ⌘+R while Xcode is active
6. The LEDs should now turn on and off
7. Close Xcode while the LEDs are on
Job done (works for me on Yosemite)
well the only problem is u have to run this trough each time you start your Mac
or just try to shortcut the operation with Automator - here is a link to the description :
http://apple.stackexchange.com/questions/4074/what-do-i-type-to-produce-the-comm and-symbol-⌘-in-mac-os-x
I hope this will help!
Peace

Is there a way to get a version of the Garage Band app that runs on version 5.1.1? I have an iPad 1 and can't get any higher iOS. The App store is telling me that Garage Band only runs on iOS 7.

HT204053 If I have an apple ID for myself and my wife has just got a iPhone for the first time how can she get the same apps as I have for my iPhone and iPad

If I have an apple ID for myself and my wife has just got a iPhone for the first time how can she get the same apps as I have for my iPhone and iPad by getting it off my iCloud?

She can't from iCloud without setting up your iCloud account on her phone. But just sync the same apps from your iTunes Library on your computer to her phone.
Your wife should setup her own iCloud account - which is separate to the iTunes Store accounts.

Try using a different browser as a test.

I am able to get the 'Home sharing' 'user and password on my Mac.
Also using IPad 2 I am able to get the ITunes to accept the user name and same password as the Mac.
However, the only way I can see the 'Home sharing; icon is in Music on the Ipad. When I tap on the Icon it asks for a password.
When I give the same password, it is rejected.
Help!!!!

Personally I think the iOS devices are poor at reconnecting - Airplay establishes that a link is available but when the iPhone/iPad has been away from the house and rejoins the network i think AppleTV already thinks it's connected with a different IP address and fails to recognise it has joined the network again with new credentials.
Something along those lines anyway.
I find that a combination of restarting AppleTV, router and iOS device tends to fix it, but not for everyone.

First question - I have Acrobat 9 on my desktop and the license seems to have been messed up. I tried to download and fis but I asked me for a disk. I don't have any idea where the "disk" is. Can I get the license update without that disk?

Second question - In anticipation of not being able to do that, I bought (at University bookstore) Acrobat XI Pro - do I need to uninstall the 9.0 Pro version before I try to install the XI version?

If you still have your serial number for Acrobat Pro there is a link to the installer here: Download Acrobat products | 9, 8

We have an iPhone 4S and can only see the top half of the screen.

We have an iPhone 4s and can only see the top half of the screen. The phone works fine as far as making calls and you can kind of text, if you can figure out where the keypad is. Is there a fix for this or is it trash? It is out of warranty and we don't have insurance on it.

Then I guess you'll have to live with a broken phone as a new one is your only option.

Hi user 1724, before icloud, we had the same issue....
so yes, the solution was to each log into the mac separately.
i kept the main itunes library and apple id, and my son made his own itunes library (which linked to the main itunes/apple id) - so we were able to maintain separate contacts lists.
but then w/ the cloud i guess we assumed the cloud would know we each have different contact lists on diff. phones, but it seems the cloud just lumped it all together -

I have the CMStorm Devastator and can't get the backlight to turn on.
