Macbook Pro cannot start properly after Yosemite v10.10.3 update

Hello,
I have a serious concern with my MacBook pro 13Inch Retina. After the recent update to Yosemite v10.10.3 on 18 April, whenever I start my Mac book, the Apple icon will not show up immediately as usual just black page. It only appear after I press the power bottom again( or sometimes by luck a 5 mins wait) then the icon will appear and system turns into login page.  This is not normal!
Anyone please help! I am not sure if I were the only one experiencing this or this is a bug come with the recent update.
Thanks!

Repair the Hard Drive and Permissions - Yosemite, Mavericks, Mountain Lion or Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list.  Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu. Select Restart from the Apple menu.
Now, download and install the OS X Yosemite 10.10.3 Combo Update.

  • HELP!!! My macbook pro cannot start up after dropping!!!

    I dropped my Macbook Pro 2.4 hardly to the ground on the right bottom days ago and it just cannot start up anymore now.
    I can hear the start up chime, but the screen is black and it shuts down automatically.
    I doubted it was because the hard drive dead, so I took out the hard drive and anticipated to see at least a folder with a question mark, but nothing - still black and powers off.
    HELP!!! Anybody has any idea?

    Contact Apple & make an appointment to have the computer repaired. Applecare does not cover accidental damage. If you want to diagnose & repair yourself - MacFixIt Tutorials

  • Facetime and iMessage on Macbook Pro Retina display slow after Yosemite 10.10.3 Update

    Hi
    I recently updated my Macbook Pro Retina display to Yosemite 10.10.3 update. I see that the Facetime and iMessage has become relatively very slow. Like for example when someone calls on my phone it takes like more than 15 seconds + to show up on my macbook. Earlier it used to be like instant!
    I started seeing this problem on Yosemite 10.10.3 update only. Also the same is the story with iMessage. When I get an SMS or an iMessage from my friends it takes like a good 30 seconds + to show up on my macbook pro.
    Just for your information, this is the version of macbook i am using
    MacBook Pro (Retina, 13-inch, Late 2013)
    2.4 GHz Intel Core i5
    8 GB 1600 MHz DDR3
    251GB Flash storage
    As Suggested by someone I also tried RESETTING my computer's PRAM. That didn't seem to help either. Can anyone help. If it is a genuine bug in Apple Yosemite, I'd like to file a bug in the community.
    Regards
    Shreyas

  • MacBook pro suddenlink email issues after yosemite install.

    After installing yosemite on my 15" MacBook Pro I have had issues with my suddenlink email account. I went through all the settings yesterday with a sudden link representative and did find a port was wrong and corrected that on my outgoing server. However I never could update my password successfully using Preferences, Account, Password. It would let me save it, but would not actually change it, as confirmed by the connection doctor. So reading some other threads here I went to my provider and changed my password there, to make sure everything was correct. I updated the passwords on my iPhone and iPad, and both accounts are working correctly (they always have been working properly). I deleted the sudden link account from my MacBook, and reinstalled it with the correct new password, it was working fine all day yesterday and then this morning when I got back on my MacBook, I have the triangle exclamation point symbol next the sudden link account again. Tried re-entering the password via preferences tab and no luck, verified with connection doctor that I couldn't connect, it gave me the same error,  verify password and username is correct. I deleted and re-installed with correct password, and it works again. Any suggestions as to why this is happening?

    There's a sequence of steps in the support article for each of several possible scenarios of a connection failure in Mail. Please describe in detail what happened when you followed the applicable sequence all the way to the very end, without skipping any of the steps. That's the starting point for any further efforts to solve the problem.

  • My late 2011 Macbook Pro is running slow after Yosemite upgrade

    Hello everyone! I'm a little desperate as this is my working computer and I'm not sure what else to do. I took it to a mac technician and they did a clean intall, checked my memory cards and said there should be no problem.
    I get it home, install the basics programs I need for work- Adobe, Chrome, Firefox, iWorks. My computer is still running very slow. The start up is slow, the internet is very slow.
    Here's my EtreCheck report. I hope maybe one of you can shine some light on the issue. Thank you in advance for all the help. 
    Problem description:
    My computer is running very slow. Even the browser when switching between tabs will show a blank page for a few seconds before showing the actual page. It was rebooted and nothing. This problem started after upgrading to Yosemite.

  • Late 2011 MacBook Pro can't boot after Yosemite install

    After installing Yosemite on this late 2011 MacBook Pro it stops about a third of the way into booting up. It displays a null sign. I can boot into recovery disk, or external HD (I don't have a backup of this system, but can boot from my MacBook Air's clone) if I use option-R or just option at startup. It won't go into Safe Mode. From the ext HD I have reinstalled Yosemite on the MBP, but it still freezes mid-boot. Disk Utility repair permissions, repair HD, zap PRAM, SMC, I've tried all of these (from reading advice here, and PM from Ogelthorpe). I have copied the Etre Report below. Suggestions?

    Drive Partition and Format
    1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. 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.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    7. Quit DU when it is finished and return to the installer. Install Snow Leopard. Download and install Mac OS X 10.6.8 Update Combo v1.1.

  • Macbook Pro Wont Start Up After Update

    Hey All,
    I was in the middle of installing the most recent update for OSX when my computer froze completely. I shut it off by holding down the power button. Now, when I start it up, right after the apple, it goes to a screen with some script in the upper left hand corner, and a box in the middle with a picture of the power button telling me I need to restart. I've restarted it several times and it just keeps going back to that screen.
    I have booted it up from the install DVD and run disk repairs and verifications, as well as checking the system profiler and utility, and nothing seems worng. I've tried starting it up by choosing to start up from the folder and it still didnt work.
    If you've got any ideas, let me know. All your advice is appreciated.
    Thanks!
    Macbook Pro   Mac OS X (10.4.8)  

    I meant to say that the system would have been made unstable after the semi-complete update (if it was in the middle of replacing a crucial system file).
    An archive and install would replace all system files, so wouldn't hurt anything. You might have to reinstall any system-intrusive applications (Palm Hotsync springs to mind, if you have that) but it will certainly fix system corruption, if that is your issue.
    After the reinstall, if you encounter a complete freeze again, then I would definitely be suspicious of hardware. Possibly the original RAM, but it could be somewhere else in the system, such as the logic board. In those cases, you would have to go back to Apple for repair. (Your Macbook Pro, that is, not you.)

  • Macbook Pro not starting up after 10.9.3 install

    Hi everyone. I have a mid-2010 15 inch Macbook Pro. After putting it off for some time, I went to install the 10.9.3 update. However, after installing the update, the computer won't start!
    A progress bar appears under the Mac Logo during start-up, but it only gets about 1/5th of the way through, when the bar disappears and then the mac shuts down. I've attempted this at least 5 times and it always does the same thing.
    I held option during start-up to boot into the Recovery disk, and tried to repair the partition (I also have a bootcamp partition), but it said it was unable to repair. What's my next step? I have a time camp back-up from 50 days ago, so I could restore from that but it wouldn't be ideal. Is there a way to backup my files in it's current state in anyway?
    Any and all help is appreciated. Thanks!

    Hey NickinTampa,
    Thanks for using Apple Support Communities.
    Looks like the computer won't start and you have tried repairing the disk. This article gives several other ways to try and resolve startup disk issues.

  • Macbook pro freezes during startup after Yosemite

    hello, i have a Macbook Pro (Retina, 15in, early 2013). I have since used it and never had any problems. i am also running the latest version of parallels (which i just updated before downloading & installing the update from Mavericks to Yosemite. Since installing Yosemite, i was able to use my macbook for about a day...suddenly during a login attempt i kept gettting the spinning wheel & the computer would just freeze.. ive been reading this comments & questions for the last 3 days & tried as much as i am capable of. I can not get the computer to boot in safe mode... i CAN boot it holding commandR...but than at that point i ran disc utility and it said no errors... I am utterly lost....this macbook doesnt come with a built in CD/DVD drive and i have NO CLUE how to properly back up anything...i DO NOT KNOW WHAT TO DO...can someone PLEASE help me using as much LAYMANS terms as possible? I truly appreciate ANY HELP!!! thank you in advance

    ... and i have no idea what else to do :?
    Return that RAM and buy either the Crucial ram (http://www.crucial.com) for your system or buy from OWC (http://www.macsales.com). I've used Cruical ram in many systems over the years with no issues, and have bought Samsung (factory fill) from OWC with no issues either.

  • Macbook pro wont start up after trying fsck -y (incorrect block count)

    my 2 months macbook pro won't start up after numerous attempts and ive tried fsck -y and it says "incorrect block count for file system.log (it should be 184 instead of 108) help please

    it just says start up disk full, its not full however it has at least 10Gb of space left.
    Your HD is full!  How large is your HD?  You should never let your hard drive get to where you have only 10-15% of space left.  You need to do some serious housekeeping.  However, you need to get to your desktop to do that. 
    Can you safe boot?  Read the threads over in the "More Like This" column over here.----------->

  • HELP!!! My macbook pro cannot start up!!!

    I dropped my Macbook Pro 2.4 hardly to the ground on the right bottom days ago and it just cannot start up anymore now.
    I can hear the start up chime, but the screen is black and it shuts down automatically.
    I doubted it was because the hard drive dead, so I took out the hard drive and anticipated to see at least a folder with a question mark, but nothing - still black and powers off.
    HELP!!! Anybody has any idea?

    Well unfortunitly it sounds like the fall damaged the laptop to the extent that it doesn't work. Your only option is to send it into apple (or an authorized apple repair) to be fixed. Since the laptop was damaged from a fall you warranty will not cover the repair.

  • Early 2008 MacBook Pro won't boot after Lion 10.7.1 update

    My 2.4 GHz 4GB RAM Early 2008 MacBook Pro wont boot after downloaded the Lion 10.7.1 upate. Upon restarting the screen went dead and now the system does not boot, as if the bootloader has been wiped out. Screen appears dead but was known to be working before hand. The hard drive spins up but doesn't sound like it is searching for data.
    Can anyone help me?

    Okay, I tried everything I can think of last night. I removed every startup process and every tool or programm that goes deeper into the system (GlimmerBlocker, LittleSnitch, Parallels). Cleaned Up every Cache I could find and refreshed every necessary Cache or Database possible. Took me a couple of hours. But still no luck - the machine doesn't boot, just in safe mode. Right now I copy all my personal stuff to a new external harddrive because TimeMachine doesn't work, after this I will do a clean install of Lion.
    It's not hardware related, it's the 10.7.1 update that doesn't work properly. By the way, the only errors remaining are:
    WindowServer - kCGErrorFailure
    ManagedClient - kCGErrorFailure: CGSPackageGetWorkspaceType: couldn't get workspace type
    SecurityAgent - kCGErrorFailure: CGSPackageGetWorkspaceType: couldn't get workspace type
    and a lot of:
    com.Apple.SecurityAgent.00000000-0000-0000-0000-0000000186A7: CoreAnimation: rendering error 506
    that's also the last one I get before the system hangs…

  • Macbook Pro won't boot after Yosemite upgrade

    I downloaded Yosemite this evening, but the installation never finished. When I get past the login screen, a loading bar will half load before the computer shuts down. I tried command option p r without success, holding the option key down while starting only gives me the option of my main drive and it doesn't work. I tried holding down command r during start, but that doesn't do anything either. Any suggestions would be appriciated.

    Reinstall Lion, Mountain Lion, Mavericks or Yosemite without erasing drive
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
    Reinstall Lion, Mountain Lion, Mavericks, or Yosemite
    OS X Yosemite- Reinstall OS X
    OS X Mavericks- Reinstall OS X
    OS X Mountain Lion- Reinstall OS X
    OS X Lion- Reinstall Mac OS X
         Note: You will need an active Internet connection. I suggest using Ethernet
                     if possible because it is three times faster than wireless.
