HT3625 Macbook pro 13 2012 not showing line in audio when connected to preamp

I have a preamp connected to the audio in/out jack on my macbook pro 13" 2012. when i plug the audio in from my preamp the sound only shows it as a headphone output and does not list it under input. i also have no button "use audio for:"

You should also ask this in the MacBook Pro forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

I lost my iphone and my macbook pro does not show the icloud in system pref. how do i get icloud on my mac?

iCloud is only available in Lion, 10.7. You will have to upgrade to Lion in order to get into iCloud. If you transfered a .mac or .me address to iCloud through mobile me, or you have another device iCloud enabled, then you can log into the iCloud.com website.

Macbook pro 2010 not showing hdd in disk utility but shows the same in usb

Macbook pro 2010 not showing hard disk in disk uility but same hdd shows when connected to usb original drive, also installed new hard disk 500gb, same result, but connected old hard disk of 500gb shows in disk utility and also able to installed os on it, tried installing lion 10.7 on it with the original and new hdd but not shows in disk utility pls help for this problem

I'm kind of experiencing the same issue now.
A few days ago, when starting up my Mini, I would get a warning that the system didn't recognize the drive with the option to ignore. I hit ignore and all seven drives would mount. Because I have seven drives attached, I had no idea what drive was giving the warning.
Today that drive failed to load up at all. I ran disk utility and after several tries, it said repair was successful yet the drive will not mount.
I'm currently running recovery software on it to see if I can copy everything from it to another drive. It is a fairly old drive, about 3 years old so it's time is short.
I don't have any suggestions but mine does show in disk utility.

Hey there krpeterson93,
It sounds like your new phone is not appearing in iTunes on your computer. Depending on the version of your OS, the instructions are a different.

Brand new MacBook Pro 2012 not booting install of Mountain Lion

Hi,
I have a brand new 15" MacBook Pro 2012 model (2.6Ghz, 8GB Ram) - works fine on OS X Lion. As I had just bought it I decided to upgrade it to Mountain Lion straight away, and here's where the problems start.
After apparent install the machine re-boots, but upon re-boot I get what I have found to be called 'the grey screen of death' where the loading icon disappears and the apple logo appears and the screen dulls slightly. I have also noticed that through the install process I lose keyboard and trackpad funcionality and the 'spinning wheel of death' froze, even though the loading icon contined to countdown the minutes till install.
I have read many threads online now about how to reboot and reinstall OS X Lion, I have done this succesfully. I managed to save the OS X Mountain Lion files to an external device and attempt to reboot that way - same problems!
How on earth do I get OS X Mountain Lion working on this machine?
From the threads I have read no one has answered this - they simply answer how to reboot into OS X Lion. Others have stated that they have been in to see Apple's "Genuis" bar and the "Genious's" cannot explain the problem and attempt to put it down to hard drive failures etc. Problem is, there seems to be a **** of a lot of people out there with the same issue - surely it's OS problems and not hardware if it's a brand new MacBook?
Has anyone else experienced this? And does anyone else have a solution to my problem?
For the record, I have updated my EFI and firmware as well as my operating system before attempting install.
Cheers,
Leigh

My Macbook Pro does not show up on my TV.

How do I make my Macbook Pro show up on my 40 inch Samsung HD TV if I have tried everything in the Help menu in Displays in System Settings?
I restarted, tried every resolution, gathered windows, detected displays, and everything but my Mac still does not show up on my TV.
I have also tried to change the settings for my TV but still it says that there is no signal.
I used a Belkin mini adapter to HDMI and I also used the Dynex version. It used to work fine once but it does not work anymore.

If the same MBP using the same connections to the same TV with the same settings on both the MBP and TV used to work, it appears there is a hardware problem. You might want to try a different TV or different MBP or different connectors.

Macbook pro 2012 not fully supporting samsung 4k monitor

hi
I bought the Samsung U28D590 monitor to use it with my Macbook Pro Retina mid 2012 model. though it connected comfortably, but the feel of the screen resolution was very poor. I checked it up with the setting, it showed me "best to fit U28D590 " and also showed 60 hrz. but somwhow, it looked like i was using a normal monitor, never felt like using a 4 k display.
Is something wrong. Need help.

You have posted to an iPad forum, I have requested the mods to relocate your post to a forum that you may get better answers.

Macbook Pro does not show up on ATV 2

Have installed ATV 2 - connected to TV with HDMI cable. Appears to connect with Airport Extreme in other room where Macbook Pro is located.
However, while I turned on Home Sharing on the Macbook Pro and also on the ATV 2, they aren't finding one another.
Tried to change name of laptop to my @me.com address, but syntax won't work.
What do I need to do?

have you tried disabling home sharing. then re-enable it, but BEFORE you press done to exit the home sharing screen check the apple tv and see if it shows up. It seems to have temporarily solved my issue and many others on this board. The worst Apple product rollout ever.

13" MacBook Pro 2012 Not Recognising USB Devices on OSX 10.9.1

Hello,
Since updating to OSX 10.9.1, one of the USB ports of my MacBook is not always recognising devices (external HDDs and Logitech Unifying Receiver), often when the other port is used.
It is the port on the right. First I noticed this problem with the Logitech Unifying Receiver, I thought perhaps it is because of the driver, but today I had to plug in my external HDD several times to get recognised and mounted. When not recognised, the Logitech Unifying receiver is not even listed in System Information, and HDDs are not listed in Disk Utility.
I had no issue with using both USB ports prior to OSX 10.9.1.
Anyone else is facing this problem?
Thank you.

Hi AMDeeb,
Thanks for visiting Apple Support Communities.
If USB devices are not being recognized reliably by your MacBook Pro, start with resetting the NVRAM:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R.
You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
You can find more information about this troubleshooting step here:

My MacBook Pro does not recognize my iPhone 4 when I connect with USB

As the subject line says, when I connect my iPhone 4 to my MacBook Pro via the USB cable, it normaaaally opens iTunes and iPhoto automatically and syncs and imports photos from the phone. But, for some reason, that doesn't happen anymore... Now when I plug in my iPhone with the USB...nothing happens.
The USB still works as a power charger. I even tried a different newer iPhone USB cable from my friend's phone...same problem. I tried both USB ports.
I update my iPhone, my Mac, my itunes, my iphoto...everything. I reset everything at least a couple times. Still no luck!
I did a Disk Utility verify check...it found no problems, the volume 'appears to be ok.'
The iPhone still syncs with iTunes over WiFi, but unfortunately I can't back up my photos from my iPhone wirelessly (I don't have iCloud set up). I want to do it via USB.
Anyone out there with any advice on how to get my computer to recognize my iPhone?
THANK YOU!!!

Ive been struggling with this problem all day, I was trying to upload my pics and videos from my iPhone 4s (version IOS-7) and my computer didn't seem to recognize my phone. Well I finally gave up. My iphone was plugged into my computer via USB, and my iPhoto would not open up automatically like it always had before I updated to IOS-7.
As a last ditch effort I happened to open up my software updates in the apple icon. Lo and behold, once I agreed to update my iTunes app on my mac OSX 10.6.8, it opened my iTunes and a window popped open asking me to click on 'trust this computer'. I did that, and suddenly my iPhoto opened up and filled up with all of my iphone 4s (version IOS 7.1.1) pictures and videos! I could not find an answer anywhere online. I guess the trick is to manually open up iTunes before you attempt to upload pictures/videos from your iPhone into iPhoto.

My Macbook Pro will not install/restart for updates when I use Software Update

So when I go into System Preferences and go to Software Update, I click the Check Now Button. It looks for available updates, and gives me a box that says "Software updates for your computer are ready to be installed. Do you want to install them now?" with options to "Show Details", "Not Now", and "Install and Restart". However, when I hit the install and restart button, after hitting a few confirmations, the app simply logs me out, but doesn't restart the computer. When I restart the computer from the Log In screen, the computer reboots without installing any of the updates. I'm on Snow Leopard, is that why updates aren't installing? Am I going to have to manually download all of the updates, or at least that updates that are compatible with Snow Leopard?

There are no updates for Snow Leopard except to Mountain Lion.
Upgrading to Snow Leopard, Lion, or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer)
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
         3. MacBook Pro (Mid/Late 2007 or newer)
         4. MacBook Air (Late 2008 or newer)
         5. Mac mini (Early 2009 or newer)
         6. Mac Pro (Early 2008 or newer)
         7. Xserve (Early 2009)
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
     Am I eligible for the free upgrade?
         See Apple - Free OS X Mountain Lion upgrade Program.
     For a complete How-To introduction from Apple see Upgrade to OS X Mountain Lion.
