Macbook Pro (Retina Early-2013) will not turn on

I plugged my iPhone into my computer and was going through the process of syncing my music when my MacBook Pro just powers down completely. I've been unable to turn the computer on since then, following the Apple trouble-shooting process.
Interestingly, when I do a SMC reset, the LED color on my MagSafe charger will change to green and then back to orange, leading me to believe that it isn't an issue with either the connection to the power button, or with the logic board itself. In spite of this, no boot-up sounds, no LED lighting up on the Caps Lock button, no nothing.
Has anyone else run into an issue like this before? Were you able to resolve it?

Hello FAHQALL,
The resource below will provide some steps to try if your MacBook Pro won't turn on.  Resetting the SMC is one of them.  Troubleshooting the MagSafe adapter and installed RAM are also included.  There are links in the article for additional support if the computer needs to be physically inspected.

I hope this information helps ....

  • Installed Yosemite update on MacBook Pro retina late 2013 will not boot flashing folder with ?

    I just Installed Yosemite update on MacBook Pro retina late 2013 will not boot flashing folder with ?

    dunno, Lynn--maybe Etrecheck. trying running disk utility to verify the status of your hard drive. That may give you a basic idea. Perhaps tech tool pro.  As for it running hot, I can't say for sure. try shutting it down and using a vacuum clearner +crevice tool around the back of it.  It's been my experience that hard drives usually fail without a lot of warning, luckily you have a backup. Afterwards you can say "Yup, that went bad".  I've done a little research and found out that your MacBook Pro doesn't come with a conventional hard drive as such, but an SSD (solid state device) . It's upgradeable (up to 1 TB ) but not cheaply
    go here for more info (OWC) :http://eshop.macsales.com. For right now, I'd recommend resetting the SMC/PMU, maybe zapping the pram . to do that, reboot, hold down Apple+Option, P+R keys while rebooting. Hold down for 3 chimes, let go and let it boot. as for the SMC thing....
    I'm assuming your battery isn't removeable-shut down computer, plug in MagSafe cable . On built in keyboard, on left side, press Shift-Control-Option and power button at the same time.  release all the keys and the power button. press power button again to turn on computer
    that is all

  • MacBook Pro Retina early 2013?

    I don't understand. Today update to the MacBook Pro line... is it a real update or just a price drop? The MacBooks retina sold from now on are going to be called MacBook Pro Retina early 2013 or not?
    Just asking because I am waiting an update to buy the 15'' MacBook Retina.

    My current MBP is having trouble keeping up (it's 5 years old now), so I'm interested in the new 15" rMBP.
    I understand it just got a faster CPU and a price drop, which is great, but I'm wondering if Apple will release a new designed model later this year? A late 2013 model so to speak.  Would that be in June or at the end of the year?
    Thanks,

  • Multiple kernel panics & black screen on Macbook Pro Retina early 2013

    My Macbook Pro Retina (early 2013, 8GB ram, 250 GB hard drive) has been experiencing multiple kernel panics forcing rapid-fire restarts of the computer multiple times within a very short time frame. This is followed by the screen staying black even if the computer is on (keyboard lit up, can hear volume buttons) but nothing is on the screen. Once the screen goes black, I have to employ some combination of manually shutting it down (by holding down the power button) and then turning it back on (+/- doing an SMC reset) to get the screen working again. I also tried a PRAM reset once, but it didn't seem to have any effect, and I've repaired the disk permissions. 
    This issue has happened multiple times in the past week. It seems to vary as to how long it takes to happen again (could be a few days, could be less than an hour), and it has happened during multiple different activities (surfing the web, using Word, using Mail). I have experienced this both on Mavericks and after updating to Yosemite over the weekend.
    I took it to the Apple Store on Saturday and while the Genius saw that the screen was black when I initially brought it in (even though the computer was on), we couldn't recreate the issue and the diagnostic tests he ran showed nothing. It even started back up fine for him. I thought I was OK, until I had another round of kernel panics + black screen this afternoon. At this point, doing a normal restart of the machine results in a kernel panic before it even makes it off of the loading screen and then a black screen.
    This time, I checked the logs and saw the panic report included below. I don't know enough about this to understand what it means, but hopefully someone else does! Some internet searching has suggested that it might be a problem with the GPU (and the log below says GPU panic). Help, please!

  • MacBook Pro Retina Early 2013 ME665xx/A same body like MacBook Retina Mid 2012 MC976xx/A ?

    Hello,
    I have a MacBook Pro Retina Early 2013 ME665xx/A. Does it have the same body like the MacBook Retina of Mid 2012 MC976xx/A so that a case for a MacBook Pro Mid 2012 fits on my Early 2013?
    Much thanks

    If they are both the same size (as in, they are both 15inch). Then it will fit fine!

  • Проблема с MacBook Pro Retina Early 2013 (256Gb SSD)

    У меня MacBook Pro Retina Early 2013 (с 256Gb SSD).
    Куплен в апреле.
    На гарантии.
    Три недели назад отнес ноутбук в официальный сервис центр с проблемой: не видит SSD (не загружается, выдавая разные ошибки).
    В сервисе продержали неделю - вернули с диагнозом: почистили контакты SSD, сбросили настройки питания (cmd+alt+r+p при загрузке).
    Ноутбук проработал неделю. Теперь снова та же проблема. Пока спасаюсь cmd+alt+r+p при загрузке, но это не дело.
    В чем дело и кто в Apple мог бы помочь разрешить проблему?

    Еще один симптом - после появления проблемы иногда в простое сильно нагревается верхняя часть ноутбука (под дисплеем слева по ощущениям) и начинают орать вентиляторы.

  • Macbook pro retina early 2013 vs macbook air 2013

    I currently have a macbook air 2013 edition  13" with the 1.3ghz haswell chip and 4gb of ram and 128gb flash storage.
    Which would be better for me to keep this macbook air or swap for a early 2013 macbook pro retina with 8gb ram and 256gb ssd +200 dollars
    In gereral which do you think would be the better choice.
    Thanks

    It would appear  that the retina would be a good deal.
    Do you know the other party?

  • HT201257 Fan on my MacBook Pro came on and will not turn off, what could be wrong or how do I fix?

    The fan on my MacBook Pro came on out of no where and will not turn off. The computer is not heated nor are any applications running in the background. The seems to be going on full blast. Before now it worked fine. Would turn on or off when need. Please advice what could be wrong or if ther is anything I can do to fix or troubleshoot. Computer is not even a year old.

    LexSchellings: Now I know why you wished me luck and hoped everything would clear up asap hehe. I've been doing some reading and it is quite possible that my MBP late 2011 is sadly part of the probably million of MBP's out there with logic board issues. I am glad I am under warranty (still have to wait and see what apple techs decide on my comp) and sad that my comp will probably be done with in a few years. Not even 4 as it turns out. I can honestly say my old iBook G4 was amazing gave me 8 great years. Never had an issue with it.
    Something funny is that about 10 to 15 mins ago the fan on my comp (the only indicator I got of any issue going on) quite down and the comp was working perfect. It has been running really slow since I noticed the fan being over worked even if nothing is running. Then it started up again and once again quite down, functioned well for like 10 seconds and started being noisy and slow again.
    However there is an issue that bugs me, if according to my AHT results it is a faulty logic board how come my comp is still functioning? Of course being slow and noisy. I've read on some sad stories on here
    Wish me more luck and send me lots of good vives. Going to need them. Especially if I end up not being able to fix the comp.
    Apple is letting me down and to think I just purchased an iPad mini for xmas :/

  • MacBook Pro is charging but will not turn on

    Hi!
    So my laptop has been dead for about a day. I recently plugged in the charger for it to charge. There is an orange light that is on when I plug it in, and there are the green dots on the left side to show that it is indeed charging. Although when I press the start button down, it will not turn on. I do not hear the hard drive running when I press the button. The white light on the bottom right side of the keyboard is not lighting up either.
    Any suggestions?
    Thank You!

    Please make a Genius Appointment and take it in for service.

  • AirDrop between iPhone 6 plus (iOS 8.1) and MacBook Pro retina early 2013 not working

    Hi there,
        Can somebody please help me. I ent to transfer so videos that I have saved via airdrop To my MacBook pro from my iPhone 6plus.
    When I try to send via airdrop, neither my phone shows the MacBook as available not does my MacBook show that my phone is available to send/receive files via airdrop. I have wifi and Bluetooth activated. Please can somebody help? I can't email the files because they are too large for that.
    Thank you.

    Hey romeopatel,
    I see that you are experiencing some issues with AirDrop. I have an article with some information for you about what to do if your device is not appearing when attempting to AirDrop:
    Mac Basics: AirDrop lets you send files from your Mac to nearby Macs and iOS devices
    http://support.apple.com/kb/HT6510
    Don't see who you're looking for?
    When you select AirDrop, OS X looks for other Mac computers and devices that are nearby that also use AirDrop. If you don't see someone in the AirDrop window, here are some things to check.
    Preventing senders
    You can prevent people you don't know from sending you files, or you can allow everyone. If you don't see a recipient in the AirDrop window, they might only accept files from people who in their Contacts list. Ask them to add you in their Contacts app, or have them select the option "Allow me to be discovered by: Everyone" in the AirDrop window.
    Sending files to and from an older Mac
    If a Mac you're using with AirDrop was manufactured before 2012, you can send and receive files with other Mac computers.
    On the sending Mac, click "Don't see who you're looking for" in the AirDrop window.
    Select the option to "Search for an Older Mac."
    On the receiving Mac, open a new Finder window and click AirDrop in the sidebar.
    Tips for sending files
    Make sure Wi-Fi and Bluetooth are enabled on your Mac and your iOS device. Although you don't have to connect to a specific network, Wi-Fi needs to be on to send and receive files using AirDrop.
    Move your devices closer together. AirDrop is designed to work within a range of approximately 30 feet (9 meters). If you need to send a file to someone farther away, consider using File Sharing, iCloud, or email instead.
    If you're using a firewall on your Mac, you won't be able to receive AirDrop files if you have enabled "Block all incoming connections" in the Security & Privacy pane of System Preferences.
    Make sure your devices meet system requirements for AirDrop.
    System Requirements
    To see if your Mac works with AirDrop, make sure you’re in the Finder by clicking the desktop (the background area of your screen), or by clicking the Finder icon in the Dock. Then, check to see if AirDrop is listed as an option in the Go menu. If you don't see AirDrop listed, your Mac doesn't support this feature.
    In order to transfer files between a Mac and and an iPhone, iPad or iPod touch, your iOS device needs iOS 7 or later installed and your Mac needs to be a 2012 or later model. To transfer files between two Mac computers, you need one of the Mac models listed below and OS X Lion or later.
    MacBook Pro (Late 2008 or newer)*
    MacBook Air (Late 2010 or newer)
    MacBook (Late 2008 or newer)*
    iMac (Early 2009 or newer)
    Mac Mini (Mid 2010 or newer)
    Mac Pro (Early 2009 with AirPort Extreme card, or Mid 2010)
    *The MacBook Pro (17-Inch Late 2008) and the white MacBook (Late 2008) do not support AirDrop.
    For help identifying your Apple product, choose About This Mac from the Apple menu, or refer to the Apple Support website.
    Thanks for coming to the Apple Support Communities!

  • 13" Macbook Pro Retina Haswell vs 15" Macbook Pro Retina Early 2013 Refurbished

    Interested in buying my first mac this year so i'm weighing the options. Im looking to spend around $2000 for a retina macbook pro, and im trying to decide between:
    13-inch: 2.6GHz
    with Retina display for $1929
    Specifications
    2.6GHz dual-core Intel Core i5
    Turbo Boost up to 3.1GHz
    16GB 1600MHz memory (upgraded from 8GB)
    512GB PCIe-based flash storage1
    Intel Iris Graphics
    Built-in battery (9 hours)2
    And,
    Refurbished 15.4-inch MacBook Pro 2.7GHz Quad-core Intel i7 with Retina Display for $2199
    Originally released February 2013
    15.4-inch (diagonal) Retina display; 2880-by-1800 resolution at 220 pixels per inch
    16GB of 1600MHz DDR3L SDRAM
    512GB Flash Storage
    720p FaceTime HD Camera
    NVIDIA GeForce GT 650M with 1GB of GDDR5 memory
    I should note that these are the educational discounted prices
    I've already eliminated the new haswell 15" (base model) from my options as it seems like it wasn't that much of an upgrade to the previous gen.
    Now the main thing i'm concerned about is longetivity, in that I want to be able to keep this laptop for 5+ years before changing to another. So im just wondering which would be the best for keeping up to the paces of future technology (future-proofed).
    The things I would be using it for would be:
    -Univeristy school work, so portability and battery life are a bonus but not a requirement for me.
    -Occasional Gaming (will want to install windows 8 on it) (Not sure how well iris graphics compares to the gt 650M)
    -Document Processing
    -HD video and possible editing,
    -Occasional Photoshop editing
    All replies are appreciated, thanks!

    If one of the things you're after is getting the most computer for your money, consider that the 13" is a dual core i5 processor, meaning two cores is what you start with. I'm not sure if hyper-threading is available to take it to an effective four cores. The i7 is a quad core processor but since it can do hyper-threading, you effectively have 8 cores to work with, not four. If you want to install Windows 8 as a virtual machine rather than in BootCamp, you'd need to divide up your cores between your Mac and your virtual PC, and the i5 doesn't give you as much to work with.
    The 15" came with Mountain Lion and you have the option of upgrading to Mavericks for free. The 13" offers no choice; it's just Mavericks, and considering the long list of complaints on the Mavericks forum, do you really want to be stuck without a choice?
    And then there's screen real-estate. The 15" obviously has more, but you can extend the resolution beyond what Apple limits you to without going all the way to native resolution on both rMBP's using an application like Eye-Friendly (e.g., on the 15" 1920x1200 is the highest Apple approved resolution, but you can go to 2048x1280 or 2560x1600; native is 2880x1800). However since the 15" is (obviously) bigger, the stuff on the screen stays more usable (i.e., visible) at the higher resolutions.
    Finally, while the PCIe SSD will be faster than the SSD on the 15", the PCIe SSD is permanent; the SSD on the 15" is not meant to be removed (and doing so would void the warranty if you don't put it back), but it isn't permanent so future upgrades may be possible.

  • Extremely slow download, internet, MacBook Pro retina early 2013

    Hi All
    I hope someone can help me.  I have an early 2013 MacBook Pro with 16GB RAM.  I purchased it around the end of June 2013, and it has been upgraded to Mavericks 10.9.2.
    For as long as I can remember, this computer has been excruciatingly slow.  Downloads of some thing like 400MB can take many hours.  Contrast this with downloads on my old ASUS netbook which can download this amount in a matter of minutes on the same network.  My MacBook Pro is also noticeably much slower than any other devices (old ASUS, iPads etc) when surfing he internet - to the point where it failed to load an image rich apple page.
    I have look into various forums but can't seem to find a fix for my particular model - although I note that many people are having this problem with Mavericks.  Can someone please help?
    Thanks in advance.

    I would have a look at your router before digging any deeper for problems with Mavericks. I am assuming that you are connected to the Internet wirelessly? Using your MacBook Pro, what speeds do you get at -> http://www.speedtest.net/?
    Is your router single band or dual band? Are you in the US?
    Call back,

  • MacBook Pro 15" (Late 2013) will not install Windows 8.1 Pro under Boot Camp?

    Have spent many hours trying to sort this out. I was told this morning in the end by a 'Senior Advisor' @ Apple that Boot Camp does not support Windows 8.1 Pro so effectively it seems like my only option for a new machine purchased earlier in the week is to return for a refund.
    This despite the Apple Spec saying "
    Windows 8: Windows 8 or 8.1, Windows 8 or 8.1 Pro (Boot Camp 5 only)"
    The subject has been aired in thread https://discussions.apple.com/thread/5474320?start=585&tstart=0 but it has been suggested I post a fresh thread.
    I have purchased a new 8.1 Pro license, so this is not an upgrade. I have followed the Boot Camp instructions, including getting the update for this model spcifically, but the nearest I got to a successful install returns soemthing of the like 'Unable to update boot settings' or the like and installation cancels. My machine is a mess I guess now, but in a final effort - does anyone have the step by step 'idiots guide' to working through the setup successfully? I don't want to get involved in massses of messing around with files as this should clearly not be necessary for achieving an advertised solution on a new machine bought within the last week should it?
    Appreciate any help - I have up to seven more days left in my option to return for a full refund..... and maybe buy a Dell instead?
    PS : We have many Apple products, Air, ipads and iphones so would dearly like to sort this out if possible.
    Thanks for any help...

    8/8.1 will install fine but there's some stuff you need to do before starting to ensure no issues
    purchase a retail 8/8.1 license
    use only a USB2 flash drive
    get a clean 8 or 8.1 ISO
    newer machines are more selective with the ISO for some reason (ISOs that worked to install Windows on many different older Macs would not work)
    if you've made lots of changes, hacks and adjustments trying to get this work on your own, you should clean install OSX first, do not restore from time machine and start at step 3 to get Windows installed, you can go back later and copy files back to OSX
    if you want to try without clean installing OSX, here goes
    open boot camp assistant (bca) and choose option 3 ONLY if it reads 'remove/delete' Windows
    open disk utility (du) and confirm that your HD now only has 1 single partition ('macintosh HD' unless you've renamed it)
    restart machine and do a PRAM reset
    open du and repair permissions TWICE
    open bca and choose all 3 options (create, download, install)
    from here, the process follows the standard boot camp instructions (http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf) but pay attention to step 3 where you do have to manually reformat the boot camp partition
    clean ISOs

  • Macbook Pro 10.6.8 will not turn off, restart, or even sleep after upgrading to OS X Mavericks

    It was working fine for the first 4 days until now, the computer won't turn off, won't restart, and won't sleep. When click on those button, the computer has no response. Also the iMessage App appears to not working as well. I tried forced turn off by holding the power button, but then it takes about 1 to turn back on. And now after it is on ago, it won't turn off again. And the Imssage is not working again. Other apps seems works just fine. Any suggestion?
