Macbook Pro mid 2012 unable to shut down normally

     I'm currently running Mavericks, and recently my mac has this problem where it will randomly become unresponsive to the shutdown signal, no matter how long I wait, and I am forced to hold down the power button until it shuts down that way. Paired with this issue is the inability to open new applications (the application symbol bounces in the dock like it should, but instead of opening it just disappears and nothing happens) and to save currently open files, regardless if this is in something simple like TextEdit or a program like Eclipse. In this last case, I just get an error message that straight up says "unable to save file," so I can't even leave my mac on at all times as a temporary solution because I'm unable to do any work without losing it.
     I'm unable to reproduce this problem at will because it just happens for no reason at random times.
     Usually after the hard shut down I can turn it back on and it will boot normally and everything will run smoothly until the next time this happens again, which can be as soon as 20 minutes later. Every now and then, however, I get this weird thing
and my mac just freezes, forcing me to hard shut it down yet again.
Anybody know what the problem could be? Also, I'm new to this forum so if I didn't provide enough information just let me know and I'll do my best to clarify.
Many thanks.

If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode.
*The linked support article refers to OS X 10.9 ("Mavericks"), but the procedure is the same for OS X 10.7 ("Lion") and later.

Macbook pro (mid 2012) unable to read DVDs

I inserted DVDs into my Macbook pro but it's unable to load showing the following message:
Then I tried using VLC but still had no luck. The bug report was shown as follows:
I'm not sure if it's a problem of area code or something. My Macbook pro is set to the spanish language and it's being used in the UK (automatically detected). The DVDs were bought in the UK. Is there any setting I have to add or change? Thanks for your help!

I have this same problem. My Macbook Pro, completely new (2012), set to spanish language, and being used in Mexico. I inserted a couple of dvds yesterday and none of them were read. I also tried DVD player and got the same message, and then VLC, same thing as above. I tried quicktime as well and nothing happened.
DVDs are original, so I don't get why I'm getting this problem.
Is there a software problem? or is it the drive? How can I solve this?
Help appreciated!

Macbook pro seems not to be shut down normally after adding one more user account

after i have created a new user account and i tried to shut it down, it does not appear a white background on the screen to let me know if the pc was in the process. After few second the screen becomes black and it shuts down.
I tried to turn on the pc and it works normally but when i shuts my pc down, the same problem appears.
I have already delected one user account but the problem still appears.
I am not sure is it ok or not?
i am a new user to apple product.

I experienced the same problem. What I noticed that problem seems to occur more often when bluetooth is switched on. For instance, today I wanted to switch off bluetooth connectivity before switching off laptop completely. The bluetooth icon in menu bar from some strange reason froze completely, rest of programs and OS were working fine. When I wanted to switch off the laptop it happened again, it froze and the only way to switch it off was to hold power button.

Unable to erase Samsung Pro 850 in Macbook Pro mid 2012

I have just installed a Samsung Pro 850 in a 13" Macbook Pro mid 2012.
I boot the computer with a USB stick with Yosemite image on it.
When I try to installe Yosemite on the disk it fails with an error "Unable to unmount volume for repair".
After that I have tried to erase and partition in disk utility, but that fails with "
wiping volume data to prevent future accidental probing failed".
It looks a lot like this old discussion:
Disk erase ailed with the error :wiping volume data to prevent future accidental probing failed.
I have tried putting the Samsung Pro 850 in an external USB case. When it sits in the USB case I can easily install Yosemite on it, and erase and partition - no problem.
Tonight I took the disk to a friends 2011 Macbook Pro 17" (running SATA 2). He had no problems whatsoever with the disk.
Why does it only fail in my MBP?

Did your friend also try using your USB flash drive installer? Have you tried this method:
Install OS X Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

MacBook Pro Mid-2012 Overheating?

I just got my MacBook Pro Mid-2012 less than a week ago, but I am already having problems with my MacBook Pro heating up. It gets to a temperature that almost burns my hand when I touch the bottom. My old MacBook didn't do this. I was running Windows last night and it just shut down, presumably because the computer overheated. However, I have no idea how to measure the temperature without installing additional software. How do I do this? It is normal for the MacBook to do this? If I take it to the Apple Store and they agree that there is a problem, should I just wait until WWDC to have them swap it out (potentially for a new MacBook)?
I also cannot tell if the fan is actually working.
Thanks!

As your MacBook Pro was bought only a week ago, return it and get a new one. It's not normal because your MacBook turns on fans automatically when the temperature rises. Moreover, if you run Apple Hardware Test, it will probably give you an error referring to the fan, so it's better to return that computer and get another that works correctly

MacBook Pro Mid 2012 not starting up after Yosemite Update

I'm using a MacBook Pro mid 2012 model , enrolled into Yosemite Public Beta Program ...
After the official public launch , app store suggested that i rather update from beta 5 to beta 6 , as downloading extra 5 gig of OS data seemed unnecessary for me , I just updated from the app store.
Post the update , after shutting down my MacBook , I tried starting it up after 8 hours , it failed to respond to any of my prompts .
Keyboard not responding
Power Button not responding
Li-Po Battery indicator alone works ,
When plugged MagSafe , it indicates charging .
The Sleep Indicator (in the front - that of hard disk drive ) blinks occasionally.
Later, when i tried powering up with MagSafe , It booted luckily , after some 20 hours of work , i shut the system down ,
Again when i tried booting up , it failed .
The problem persists since 3 days.
I tried booting up in Safe Mode - No result
Tried Verbose Booting up - No result
Cleared NV RAM - No result
Cleared SMC as Apple instructed for Intel Based MacBooks - No result.
Removed Battery and kept aside for a while , After an hour tried powering up , It booted up , Went till Apple Logo , The loading bar was some 45%
Then it started to go down with a black screen ,
It never starts up again.
After regular intervals of removing and installing battery , it starts up to white screen and goes off.
I am really worried and desperate now.
I am not sure whether my HDD is dead or my Battery is dead or my Logic board is dead or my Yosemite Install was not right ?
After hours of online research , nothing seems to be helpful .
People at Apple Care (Premium ReSeller , India) are so irresponsible in attending the issue ,
They say its helpless without even doing some basic troubleshoot.
Where would it have went wrong and What am i supposed to do now ?
PLEASE HELP !!

darkrider92,
I have the same model MacBook Pro as the one that you got from your mom. Were you able to install the 10.6.8 update successfully onto the factory drive? Were you using the factory RAM when you tried to install the 10.6.8 update on the SSD?
Have you checked the Web site of the SSD’s manufacturer, to see if there’s a firmware update available for the SSD?
You can download the 10.6.8 update outside of Software Update from Apple here; in case you need to try to install this update several times, running it from your local disk would be more convenient than waiting for it to download again.

Since installing os x mavericks can't shutdown macbook pro(mid 2012) is there a fix?

since installing os x mavericks can't shutdown macbook pro(mid 2012) is there a fix?

I did the SMC reset and that did shut down the computer (did not notice if the power adaptor lite blinked) when pushed power button (after waiting approx. 30sec.) to see if computer would display same message -- it did! Here is report:

Friends Macbook Pro Mid 2012 model evo to my computer upgraded with 840 samsung 6 months ago, and I was using it without any trouble. But in the last one month I got on my computer machine kernel cache error. With the installation and opening of the original disc, but SSDs doing was making trouble. I gave the service SSD y not change no matter what problems they have learned and change. Carbon Copy Cloner now and again with mac dupper supper time machine backup or recovery took my board if I did not open and the kernel fails again on cahce. Trim off mode, albeit not have them, even if I've tried everything. In the end, many SSDs ef firmware samsung site about a problem with the data transfer rate is found. Now I guess my goal to downgrade version 1.6 of EFI y How can I do my job, you'll see that information transaxle. Downstairs you can see information about my computer.

It may have nothing to do with the firmware of your machine. What is the Kernel cache error? Bootcamp is one option to upgrade firmware of the SSD.
The Samsung SSDs come with Magician, which should allow you test the performance and integrity of the SSD. If it is a HW issue, you should be able to get a replacement. Samsung originally had offered a 5-year warranty on the 840 Pro SSDs.
The other option is a down-loadable .iso from Samsung Support website.

My Macbook pro Mid 2012 Model Seems to be using too much RAM

Hello everybody, I recenlty bought a Macbook pro Mid 2012 Model and I absolutely fell in love with it! I use it everyday for school, work, and for my musical hobby.
I haven't had a single problem with it until recently, and it seems like the RAM memory is being all used up without me even running programs. This problem barely started rougly 2-3 weeks ago and it's becoming annoying. I do plan to upgrade the ram soon seeing as the extra RAM will help run my engineering software I'm going to be using.
Anywho I'm just looking for tips, suggestions or answers as to why this problem is occuring. Also heard from a fellow employee that Google Chrome can cause this problem with RAM and battery life as well.

Stop using Chrome for any number of reasons and stick to Safari. An aspect of OS X memory management is to take over as much memory as possible in order to better manage the memory, however, this does not mean you are running out of memory. You only run out of memory when you try to run too many applications concurrently given the amount of RAM you have. You will know when that happens because the computer will slow down, you will see the beachball a lot, everything you do takes forever, and the hard drive will be grinding away.
About OS X Memory Management and Usage
Using Activity Monitor to read System Memory & determine how much RAM is used
OS X Mavericks- About Activity Monitor
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

My Brandnew 15 inch Macbook Pro (mid 2012) Crash to Black Screen

My Brandnew Macbook Pro (Mid-2012) just purchased last August 2012, i turned it on and watched some movie online and youtube when all of a sudden, the screen would turn black and the machine would not react to any keyboard or mouse input anymore. All I could do was hold down the power button to turn the computer off.
i really appreciate your ideas about this problem...

If it has happened more than once, make a "Genius" appointment at an Apple Store to have the machine tested.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to bare metal from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed.

My iPad 3 is not charging on my macbook pro mid-2012. It was working yesterday and it is not working now, and I'm trying to transfer files between them. How do I charge my iPad with my macbook without having to be a completely new computer?

I am trying to transfer files between my ipad 3 and my macbook pro mid-2012 and they will just not connect. I connected them yesterday and it worked fine. And i can not air drop these files into my ipad it has to be done through itunes. And i can not afford to buy a new computer. How do i get these two to connect without having to buy a completely new computer?

Computer USB ports, regardless of the computer maker, have a relatively low power output and thus are not good chargers. They will charge but it takes a long time. You should be charging your iPad from wall power, or a more powerful source like an in-car charger.
Buying another computer will not change that.

My Macbook Pro (Mid-2012) won't connect to an external display using my MiniDP to VGA Cable.

I'm on a Macbook Pro (Mid-2012) on Mac OS X 10.8.3 (currently downloading the update to 8.4). When I plug in my Mini Displayport to VGA adapter to my Mac, the screen flickers blue for a second and the Display Settings window detects the other monitor and allows me to rearrange the screen, but it does not project anything onto the other monitor. However, I tried connecting an Apple Thunderbolt Monitor to this computer today, and it worked. This wasn't a problem before, as I was able to connect this Mac to other LCD projects before. Furthermore, I don't think it's an issue with the adapter either because it's relatively new. I also tried plugging in the adapter of another Mac (which was working fine) into my Mac, but it didn't work either.
Here's what I've tried:
1. Restarting the computer with everything plugged in
2. Pressing Command + F1 when it's plugged
Any advice would be helpful!

Can I use my macbook pro mid 2012 as an external display using thunderbolt port

Hi,
I want to use my macbook pro (mid 2012) screen as an external display for a raspberry pi using a HDMI to Thunderbolt cable, via the thunderbolt port on the macbook pro. Would this be possible? Can the macbook pro's thunder bolt port act as an input and is any additional software required?
I look forward to hearing from you.
Thanks in advance!

You are referring to Target Display mode. Target Display mode can only be used in 27-inch iMacs and iMacs with Thunderbolt, not MacBooks Pro > http://support.apple.com/kb/PH11302
Unfortunately, you can't use the MacBook Pro as a display. It doesn't support the monitor mode
