MacBook Pro - display goes black

I have a Macbook Pro 1 year.  At the start, everything seems normal. I put my password, the desktop appears briefly, and then it goes black.  It works fine on account of "safari only" invited.

Any thoughts on the difficulty or trouble shoot?

Thank you

Stuart

  • After restoring from Time Machine MacBook Pro displays all my pictures, Documents etc. as 'other '.

    I recently installed a new HD in my mid-2010, MacBook Pro that the original was defective, I then restored from a time Machine up which was recorded on an external drive. My MacBook is now going great but I noticed the problem with how my saved items are displayed, I have about 110 GB of Photos, documents, etc. and all are showing as 'Other' when they should be distributed in the divisions 'Apps', 'Movies', etc.. I'm not sure how to solve the problem, I tried a Migration Wizard, but it says 'User needs Attention' so don't know where to go from here really. Any ideas?

    If you use the 'about this Mac' view, be aware that there is a bug in the program that it generates and should not be relied upon.  Sometimes, but not always, he will correct a reindexing of Spotlight:

  • Any Creative cloud application starts and the macbook pro fans going crazy

    Hi, I'm updating cloud creative apps every time Adobe updates.

    Recently, I discovered that my macbook pro fans are going super fast with the latest updates of any application (Photoshop, Illustrator, In Design and the latest app for Creative Cloud etc.).

    Yesterday I was working on Illustrator and fans were running hot, the app said this use of memory, it was almost complete and the UI of Illustrator went to alignment mode.

    Closing the app and restarting, the problem disappeared.

    But every day, whenever I open an application CC, the fans become noisely and they go very fast.

    I appreciate any kind of help.

  • MacBook Pro display problem

    Hello members of the community.

    As of recently, I have noticed some glitches when feeding on my MacBook or awakened from his sleep.

    The colors are distorted, usually with pink, green, or yellow blobs. Blobs cannot entirely replace the colors, they appear to be contained in a element would normally be. For example. the menu bar will be partially pink and white, but pink does not leave the menu bar in this area, and the Office has green lines on it.

    I tried to take a screenshot, but the problem resolves in about 20 seconds, but it's a recurring problem.

    It happens when I wake up, connection or not. I had also certain powers serious and problems of performance, such that my MagSafe LED would not illuminate when plugged on rare occasions, fan could turn unnecessarily, graphics performance were SUPER slow, and the health of my battery was running out quickly. I actually ran a report on the system at 2 different times and my quality of full load is depleting of 1.2% per charge cycle, which is very worrying. I went from 6281 mAh mAh 6138 maximum capacity after two cycles of load. I'm tracking closely it because at this rate, my battery will survive only at load cycles about 150 instead of the 1000 expected, gives me the idea that this could very well be a bad battery. The computer is also warm to the touch while you sleep, not connected to the power supply. I NAP active but even taking into account should not be hotter my iPhone did the same thing.

    I have reset the SMC, and it solved a couple of problems. The charger works fine now and my performance improved considerably (which made me feel better, either it is a high-performance laptop, a 11-inch MacBook Air should not he surpass), and battery life has improved. I feel even if it uses a lot of power in his sleep. Maybe I need to turn off the NAP and see if that makes a difference. The graphic bug still persists however, and I don't have enough time to see if the max battery is depleting again.

    In regards to the bug, is there something that can be done? Basically, I want to assure you that I took all appropriate measures or if someone else has this problem to see if it can be software related instead of my computer.

    I have the entry level MacBook Pro with the retina, last generation.

    Any constructive contribution welcome!

    See you soon.

  • 2012 Macbook pro display problem

    Hi everyone, so I bought a used Macbook 2012 pro and this is my second day with her. I picked it up upward with one hand the other day (I know you shouldn't) I tried to grab the book I had sitting under. Anyway, when I did, I got vertical lines running through the screen! I ask it immediately and simply applied a bit of pressure again left (I held from same side) and it happens again. The right did not have that. In addition, the computer went ahead and rebooted on its own a few seconds later. I'm new to Mac and I was wondering if it's just because I put pressure or if the previous owners damaged in anyway. I have 14 days to return if I have a problem.

    Thank you in advance!

  • Latitude E7440 display goes black / white after "starting Windows."

    I suspect that he is an out-of-the-box issue (like the power button lights, either), but maybe I'm missing something... This particular unit fired upward, as planned and took our standard image. Somewhere along the way (probably during one of its reboots), I noticed that the screen is out. Turn down and the back didn't solve it, or don't have reset the BIOS. Dell diags run without problem and I can start Windows in Mode safe... but whenever I start Windows normally, it removes after "Starting Windows" flashes by.

    AARRGGHH! I'm kicking myself. It was something I discovered some time ago and since then I forgot... I had stacked them! I have closed an E7440, placed another on top of it and proceeded to the image of this second unit. At some point, I must have changed it so slightly... put it right above all that the devil is in the cover of the display of the unit of the first! (A magnetic field, is my guess). And "in white" is the second display unit... hit the light of the power button, and as a bonus. It worked as planned, when I moved this unit to another place, in order to tap into a flat HDMI. And it is blanked, as soon as I put back it on top of the first E7440. Mystery solved.

  • MacBook pro screen flashing external display connection

    Whenever I connect a display remotely on DVI (tried both Apple DVI-> Adapter Mini DisplayPort customized DVI-> HDMI adapter), my Macbook pro display blinks for a long time, like 1-2 minutes before you succeed. This does not happen with VGA (I tried Apple VGA-> Mini DisplayPort adapter). He is shown here:

    https://www.YouTube.com/watch?v=dLmI82DDvXw

    It's annoying as *. For example: whenever I visit the coffee machine or the bathroom, I have to wait 1-2 minutes until I can get back to work, because the screen was turned off until I can come back. And don't suggest me to extend the period of closure, which is not a viable solution. It happens every morning so when I get to work and turn on the computer.

    Any help would be greatly appreciated!

    See you soon

    All by using the computer to randomly screen goes completely black.  After a few attempts at tapping trackpad or a bite or two, screen turns on but then log on to the computer.

    Hi James,

    Thank you for using communities Support from Apple! I'm sorry to hear that you are having these problems with your MacBook Pro. I'm a bit ambiguous on the screen exactly who you see when you log in, but according to your description it looks that your computer may be involuntarily go to sleep. If this is the case, you can find the troubleshooting steps in the following article useful:

    If your Mac does not sleep or wake up when expected - Apple supports

    As mentioned in this article, another possibility on laptops like the MacBook Pro is that the screen closed sensor may be triggered unintentionally. There is a small magnetic sensor in portable computers and sometimes, being close to things like briefcases magnetic closure or magnetic jewelry can cause him to think that the display was closed, which then puts the machine in a locked sleep state. If possible, you can test the issue on an office open without any potential source of interference.
