MacBook Pro freezes, screen starts shaking and shuts
I am facing a problem that after starting to use the macbook for a few minutes. Screen suddenly starts to shake quickly. Everything freezes, and if all the sounds played, last moments will continue to repeat. This happens for like 10 seconds until the computer turns off completely. https://www.YouTube.com/watch?v=jpvRcQLdWXc
My MacBook pro is mid 2014 13 "version. I guess it started to happen after updating to 10.11.4. I tried to reinstall and the problem is still there. Test hardware receives no error. I figured it could be a heating problem. But after, it seems that this happens even at ordinary temperatures. This screenshot is just taken immediately after a crash.
I fixed it by clearing the NVRAM.
Here's how to reset your PRAM:
- Turn your machine off. Yes, while down, no sleep, or a disconnection.
- Press the power button and press command-option-p-r. ...
- Hold these keys down until your Mac what it charges again and you here the startup chime.
- Release the keys and let your Mac restarts normally.

help my macbook pro retina 13inch started itself and turned off while in the case
as the title, my Macbook pro retina (bought in 2014) is transformed and then turn off 5 minutes later while in his case today, I only noticed after reviewing the event log and seeing a start and stop. How can this happen? the Mac was definitely off not asleep and I did not put a timer.
It is unusual for a Mac to act this way, but this is not the first time that I heard about what's going on.
It looks like a problem SMC and is easily fixed by a reset see here reset management system (SCM) controller on your Mac - Apple Support this will most likely solve the problem.
If this isn't the case, then it could be a simple sticky switch?
A visit to a Genius Bar is perhaps a good idea if the SMC reset does not work for you, and a new OSX installation did not help.

MacBook Pro freezes when connected to external speakers
Hello
This happened to me twice in the last two weeks, both times in the same circumstances. I take my mac at the Apple Store tomorrow, but I found it worth to post the question here:
My Macbook Pro freezes when playing iTunes AND connected to an external audio system. Won't happen only when it is connected to the headphones or when you use the internal speakers. This does not happen immediately. It took about 10-20 minutes, and the specific song ends to play even if the computer is already frozen. I wonder what follows:
This could result in the latest version of iTunes (12.3.3.17)?
Or is there something funky going on with the material of my Mac?
FYI, I have a Macbook Pro, 256 GB early 2015 and I've just updated to the latest OS (El Capitan 10.11.4)
Any suggestions are welcome. Thank you!
Could be due to the failure / faulty USB hub or cables (USB or audio, regardless of your game to the top). Try to connect without a hub (if you are using one) and with different cables.
Given that the issue does not appear when you use a headset, I don't think it is related to iTunes.

I closed my laptop (Macbook pro 2012) screen with a day and immediately after 30-40 minutes his does not starts once again.
Hello Varshil07,
Thank you for using communities of Apple Support.
If I understand your message, by updating your Mac you have forced stop, or you have closed the lid, and now it does not start. To start, I suggest that try you to start in safe mode by following the instructions below. For later use, it's a good idea to not force the computer to shut down or close the lid while it is up to date, because it can cause problems.
Choose the Apple menu > shut down.
After your Mac stops, wait 10 seconds, then press the power button.
As soon as you hear the startup tone, hold down the SHIFT key.
You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.
Release the SHIFT key when you see the gray Apple logo and progress indicator.
To exit safe mode, restart your Mac, but no press during the startup.
OS X El Capitan: start in safe mode
Have a good.

I was in the middle of an update when my Macbook Pro closing in on me, and when he turned back, he wouldn't let log me into my account. I know that my password and everything, but this isn't just me connect. I have to restart the laptop? If so is there a way I can save all my documents? Please help as soon as POSSIBLE.
Was it a software update from apple? When an apple update requires a restart, it may take a little time so that it starts. If it do not, you can try a reboot. What year MBP and operating system you are running. If everything fails and you have the recovery partition. You can start on it and do a reinstall. This should not delete any personal files.

I have the macbook pro (OS 10.6.8) and the iphone 6 s. The latest version of iTunes is 11.4. When it is connected to the MAC, I get the message that itunes must be upgraded. How to synchronize or import/export files(images/music)? Fact is need to update itunes?
Hi sonalnj,
I understand that you cannot synchronize your iPhone as iTunes is requested it must be updated. I can help you with that.
According to the technical specifications for a 6 s iPhone, you need a Mac running OS X v10.8.5 or later version with iTunes 12.3 or later. Because you are on OS X 10.6.8 your version of iTunes is up to date with this OS.
iPhone 6 s Tech Specs
http://www.Apple.com/iPhone-6s/specs/Now to fix that, you need to update your Mac OS X 10.8.5 Mountain Lion or OS X 10.11 El Capitan. If you want to go to the Mountain Lion, you can do it with the first link below. The cost will be $19.99 and a code will be delivered to you if you can download it via the Mac App Store. Once you have upgraded, be sure to make all software updates to go with him to get the latest version of iTunes.
OS X Lion mountain
http://www.Apple.com/shop/product/D6377Z/A/OS-x-mountain-lionNow the other option is to move to OS X 10.11 El Capitan, and is a free update that you can do right in the Mac App Store, if you meet the system requirements. Take a look at the following article for more details on how to do it.

I have the macbook pro (OS 10.6.8) and the iphone 6 s. The latest version of iTunes is 11.4. How to synchronize or import/export files(images/music)? Fact is need to update itunes? Also you can sync ipod touch?
iOS9 on a mobile device requires iTunes 12.3 or higher, which in turn requires a computer running OSX 10.8.5 or higher. Update of the system only checks the updates for the current version of the system you run, but that itself can be updated. It may or may not be possible to upgrade your computer to the system requirements. Find your computer on the web site of http://www.everymac.com model and near the bottom of the specification of the system section, he will tell what versions of the operating system, it is able to run. If you can not run a newer system, you will not be able to sync this phone to your current computer. If she can run 10.8.5 or higher, you can either buy a download for Apple OSX 10.8 Mountain Lion code online, or you can try to install the free El Capitan OSX 10.11. El Capitan can run slower on older machines and require the additional purchase of RAM. Making a big jump in versions of system is also more likely to affect the old software.

Start my computer, it will default to the CTRL ALT DEL screen. After graduating in the login screen I enter the password. Windows will start and then the screen starts flashing and the screen say Logging Off, then restore the screen to the CTRL ALT DEL I can boot into safe mode. All other functions will not work.
Thank you
I guess you wanted to ask how to solve the problem. If then all in Safe Mode you can use system restore to set up Windows to a point when the problem did not exist.

To replace the hard drive on my MacBook Pro, I disable Photoshop 6, and I believe that I have disabled my Photoshop 5.5 (Adobe Creative Suite 5.5 Design Standard). Supposedly if you turn into a sequel they will disable all. I could, through the Adobe Web site to download and install Photoshop 6; but the Adobe Creative Suite 5.5 Design Standard is not put at my disposal for download. Any suggestions?

You can try to download the Mac version and using the serial number of the drive. LR serial numbers are normally good for both platforms.
