My macbook pro likes to take frequent breaks

so i started having some "freezing" issues with my macbook pro like 6 weeks ago. I installed techtool deluxe and ran a surface scan, and it came back with 4 errors, so i thought that the hard drive was getting ready to go out on me. I took it in to the genius bar, showed them the report from techtool, and then they ran a bunch of diagnostic tests. we backed everything up, then cleared the drive, ran more tests and then cloned everything back to the drive. all the genius bar tests came back clean, and they told me everything should be good....and it was for about a week. now i'm having the same problems again, only now...techtool doesn't find any errors when the surface scan is run..
what should i do???

Welcome to Apple Discussions!
I agree with taking it back to the genius. You could also run SMART Utility to see if it detects any errors:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
You can download the demo and run it several times for free. It is somewhat more critical than some other hard drive utilities, and may show up problems before Disk Utility or other tests will. If so, show the results to the genius.
According to SMART Utility and SMART Reporter, my drive is beginning to fail. According to Disk Utility, it is fine. I'd be more inclined to believe the more critical utility.
Good luck!

  • If possible connect my desktop (mac) with my MacBook Pro like secondary display with thunderbold

    I wnat to  connect my desktop (mac) with my MacBook Pro like secondary display with thunderbold (in the other side is working)

    Hello edolillo,
    It sounds like you are wanting to use your iMac as a secondary display for your MacBook Pro using a Thunderbolt cable. If your iMac is compatible, you may be able to use Target Display Mode, and this article outlines the requirements for it:

  • When waking my macbook pro it sometimes takes 3 opening and closings to wake up

    when waking my macbook pro it sometimes takes 3 opening and closings to wake up. Why?

    I get something like this:
    1/19/14 7:26:22.557 PM configd[18]: DHCP en0: RENEW/REBIND transmit failed
    1/19/14 7:27:27.155 PM configd[18]: network changed: DNS* Proxy
    1/19/14 7:27:27.161 PM configd[18]: network changed: v4(en0!:192.168.25.113) DNS+ Proxy+ SMB
    That failed message recurs in Console while my MBP cannot connect to my wifi. The "network changed" messages correspond to the point when my MBP does finally connect.
    Here's another piece. I have Windows 8.1 installed through Boot Camp. When I run Windows, I get no wifi problems. I don't know how much that helps, but it's a piece of info!

  • Macbook Pro, bought 2012, takes a very long time to start up/restart (5 mins). How do I fix this?

    My Macbook Pro, bought 2012, takes a very long time to start up/restart (5 mins) every single time I have shut it down.  I try not to shut it down at all now because once or twice, I have got a grey screen, and then nothing. I've held down the power button to shut down again and restart  How do I fix all this?

    Start up with your built-in Recovery disk by holding down the Command and R keys when starting. Open Disk Utility from there and use it to REPAIR your disk (you've already verified it and it came up with errors).
    With any luck, your problems will be solved. While I was there, I would also repair  permissions.
    Good luck,

  • Hello i have a question: I have a MacBook Pro and it takes 35 sek. to get starter. is that normal?

    Hello I have a question: I have a MacBook Pro and it takes 35 sek. to get starter, is that normal?
    because I think it's too long?

    What makes you think it's too long? Actually 35 seconds is pretty fast.

  • MacBook Pro Mid-2010 15" Frequent Kernel Panics

    Hello all,
    I have been experiencing frequent kernel panic shutdowns (2-3 a day) since upgrading to Yosemite. To compound matters, after each panic is an additional restart as my computer is already in the process of restarting, so I never get the crash log or option to send it, and I can't decipher the logs in Console to find them--if they exist.
    This is also happening to my daughter's identical model, and was happening after updating to 10.9.5 a while ago. I took my laptop to the Genius bar and they tried to tell me there was an issue with my video card (GPU) and that it would need replacing. I was doubtful about that diagnosis and opted not to repair (no time to give up my computer for the time needed anyway), and with my daughter's problem I seem to be vindicated. Prior to installing Yosemite I reinstalled 10.9.5 and was crash-free for a week before upgrading to Yosemite. Now the problem is getting worse, and reinstalling did not fix it.
    I am attaching my daughter's recent crash log with the same GPU incident that the Genius showed me.
    Any ideas or inspiration would be welcome.
    Thanks,
    Lou

    Thanks for your reply. But please try to understand why we (affected people) are not happy for this problem.
    Actually Apple store's staff also told me that is known "H/W" fault when i brought my macbook to run VST last week.
    Apple claimed this is H/W fault and suggested us to change logic board. The interesting thing is, this problem was existed from long time ago. Please check  this URL > MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video - Apple Support
    After read the page above, you should understand that version 10.8 or before also got this "H/W" problem but Apple tried to fix this for 10.8 or before.
    From 10.9, no more support for this problem. Until 10.10 released, you may search "GPUPanic 2010 mid macbook" from google and you will see how many people was affected by this problem.
    I also want to classify what is the definition of H/W fault. If apple can isolate the bug of the logic which was burnt on logic board (version 10.8 or before), then this is software fix for H/W fault.
    If Apple OS development team can just check our macbook version from OS and escape the "H/W" logic bug, all 2010 mid macbook will not be affected again.
    For real H/W fault, I don't think so many people will see same error at same period (after upgraded to 10.10) like this > ... AppleMuxControl/kext/GPUPanic.cpp:127
    The important point is, Apple provided OS update for us before 10.8, then we didnt know the actual graphic card's problem. 
    We trusted Apple and bought macbook. But Apple told us that our graphic card got "H/W" fault and no more support from 10.9.
    I like macbook and saved money to buy this in 2010. Using it carefully up to now. Finally Apple told me that my macbook's graphic card got problem and asked me to change(buy) logic board for fixing this problem.
    In Sep 2014, I'd just bought new macbook for my girl friend which is new model 2014 15" macbook pro. I told her macbook is very stable and have no problem. What a big joke to me......and to all affected people.

  • Old MacBook Pro slow and hangs frequently, hard drive problems?

    Hi,
    I have an old Macbook Pro (one of the originals, from about 4 1/2 years ago). Recently I've been noticing that it runs really slow, especially when its been running for a while and there are multiple programs open. It will take a long time to switch between windows, opening a tab in Safari will usually cause a spinning beach ball for 10-15 seconds and Safari crashes frequently. Other programs have similar problems, but don't normally crash. It's running Snow Leopard and has 1GB of RAM. Obviously I expect it to be slower with lots of stuff open, but my usage patterns haven't changed and its performance certainly has. The harddrive always seems to be being accessed when I have these problems.
    The hard drive S.M.A.R.T. status is "verified," and I ran the Apple Hardware Test and it came out fine. But I'm still really worried that something could be going wrong, especially with the hard drive and since I am going away in a few weeks to work on a project and will be away from my backup drive I really want to make sure any problem is taken care of beforehand.
    Does anyone have any ideas as to what could be the the problem or about anything I should try?
    Much Thanks.

    With lots of concurrent processes and insufficient memory you will experience slow performance and beachballing. This is because the OS is forced to use the hard drive to replace the non-existent physical RAM. See the following:
    About OS X Memory Management and Usage
    Reading system memory usage in Activity Monitor
    Memory Management in Mac OS X
    Performance Guidelines- Memory Management in Mac OS X
    A detailed look at memory usage in OS X
    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.
    Also, a small hard drive with too little free space and a system lacking in any regular maintenance can also lead to slow performance. See the following:
    Kappy's Personal Suggestions for OS X Maintenance
    For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard. These utilities have limited or no functionality with Snow Leopard and should not be installed.
    OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
    I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc. Other utilities are also available such as Onyx, Leopard Cache Cleaner, CockTail, and Xupport, for example.
    For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    Backuplist
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    iBackup
    JaBack
    Silver Keeper
    MimMac
    Retrospect
    Super Flexible File Synchronizer
    ynchronizer
    SuperDuper!
    Synchronize Pro! X
    SyncTwoFolders
    Synk Pro
    Synk Standard
    Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac Maintenance Quick Assist.
    Referenced software can be found at CNet Downloads or MacUpdate.
    This should give you a few things to start sorting things out and getting better performance from your computer within its limitations.
    If you have a Core Duo model then 2 GBs is the maximum RAM you can install. If you have a Core 2 Duo model then you can install up to 4 GBs but they system will only make use of 3 GBs. As for the hard drive it can be replaced. Notebook drives in the 250 to 500 GB - 7200 RPM range are relatively inexpensive. Visit OWC for pricing on drives and RAM.

  • Macbook pro 15" retina fan frequently kick in.

    HI,
    My new macbook pro 5 days old has a weird problem.
    1st it became really hot, like untouchable hot near the upper keyboard. and the fans didnt kick in.
    So i bought a cooling pad, and now it runs cooler ( w/o switching the cooler on as the cooler has a 'hole' where the mac gets hot. :-)  )
    now the fans frequently blast to 6000rpm! with no reason what so ever. so i downloaded istat. my CPU temp is around 42˚C and the ambient room temp is around 30˚C.
    It happens every 15-20 mins and lasts for 15-20 sec. I have reset SMC. Still nothing
    Also during this period the CPU is doing nothing. it's running at 1 ~2% user and 1~2% system.
    And the GPU switches from HD4000 to GT650M. and the GT650M uses ALL the memory.
    I live in India and have purchased it from a local reseller. pls advice.

    If you tried the resetting of the SMC   http://support.apple.com/kb/ht3964
    And no difference, I would make an appointment with the genius bar, for evaluation, resolve or exchange.
    You have 14 days to return/exchange
    Back up your data.
    http://support.apple.com/kb/HE57
    Genius reservation http://www.apple.com/retail/geniusbar/
    check warranty https://selfsolve.apple.com/agreementWarrantyDynamic.do
    It is un-nerving to say the least when your fans ramp up to 6000 rpm under no load, something is not right here of course.

  • MacBook Pro (Late 2013) take 3+ minutes to boot.

    Once booted, however, everything is normal. Everything opens instantly as it used to.
    While trouble-shooting, I noticed that there were many (more than a 1000 messages saying ACL found but not expected at ....
    I repaired them but doing another Verify saw them pop up again. I used ACLr8 and got rid of them fowever but this has had zero efffect on the boot time. Also, Disk Utility reports no errors.
    I should also note that this is a refurbished model bought last week and I am running with a Time Machine nackup. It is a 512 GB SSD. The machine from which the backup deribed was a 256 GB SSD. I also reinstalled Mavericks. The "old" machine took about 15 seconds to boot.
    Any ideas?

    Welcome to Apple Support Communities
    I wouldn't be worried about that bootup time. In the case of some Macs with Mavericks, startup takes about a minute, or at least in my case, so I don't think if it applies to the MacBook Pro with Retina display but it looks like OS X Mavericks has got a longer startup time

  • MacBook Pro 8, 2 Crashes Frequently

    I've a MacBook Pro 8,2 Early 2011 (15", 2.3 GHz i7, 16GB RAM). Since last month, my system started to crash frequently, from once a day to few (3-4) times a day. The crashes happened at random times - as I'm replying emails with Mail, browsing with Safari, opening files from Finder, editing a Word doc or Powerpoint ppt, etc. Each time the machine crashes, it simply reboots and goes straight to login. There is no specific pattern or steps that I observed to replicate this. Originally, the crashes happened on OS X Mountion Lion. I've upgraded to OS X Mavericks hoping that this will be fixed, however my system still crashes frequently even after upgraded to OS X Mavericks. The App Store confirms that there are no further updates for my system.
    Any ideas on how to fix this, or at least how to go about pinpointing the problem? In case it helps, my latest error report is below.
    Thanks.

  • Why is my macbook pro fan running so frequently and staying so hot?

    It seems like recently my MacBook Pro 5 has issues with being too hot.  Is this a result of keeping too many applications open?
    Thanks,

    Make sure nothing is blocking the vents.
    According to the user manual it states in part:"Do not operate your MacBook Pro on a pillow or other soft material, as the material can block the airflow vents. Never place anything over the keyboard when operating your MacBook Pro. Never push objects into the ventilation openings."
    MacBook Pro: Care, Use, and Safety Information
    "Do not place your MacBook Pro on your lap or other body surface for extended periods of time. Prolonged body contact can cause discomfort and potentially a burn."

  • MacBook Pro Running Lion Takes Out Network

    Hey everyone.  I know that there has been an issue with wifi connectivity under Lion, but this seems to be different.  I'm running a new MacBook Pro that shipped with Lion.  All of the updates are installed, including 10.7.1 that was meant to correct the previous wifi issue.  My problem is as follows.  Every time that I connect my laptop to the network at work it takes out the internet connectivity through the network.  The router is a Cisco WRVS4400N.  It seemed implausible to me that my on laptop was the culprit, but the problem consistently arises when I connect to the network, and ONLY when I connect to the network.  It does not, however, happen when I connect to any other network.  Is there something to be done about this on my end?  It's starting to get frustrating to not be able to get online at work.

    For others that may be having this issue, it seems that it was tied to the IPv6 issue that has been discussed in other posts.  I switched the setting to "Link-Local Only" and it appears to have fixed the problem.  Not sure why . . . but it seems to work for now.
    *Update* As I was posting this, the problem showed up again.  I was running the Google Music Beta.  Turned it off and the connection started working fine.  IPv6 setting is back to Automatic and still working.

  • Restart on Macbook Pro 2010 model takes forever, unresponsive screen after restart.

    My MacBook Pro takes 10 mins to restart and after it does restart the screen is unresponsive for atleast 10-15 mins. Then after it does get responsive, laptop is very slow !! Very often the screen just freezes when i am working, then slowly paints to a shade of transparent black and says "You must restart the computer, please hold down the power button" in about 5 different languages. I am not able to identify the issue. Is it a hard disk issue?

  • Macbook pro (early 2011) takes multiple attempts to wake from sleep and turn on.

    I've had a MPB since April 2011 and since I've gotten it I've had this problem. When I want to use the computer, whether from deep sleep or simply turning it on, it sounds like its beginning to turn on but then it makes this clicking noise and stops.
    My computer does not wake up from sleep with the press of buttons like it should. I have to press the power button to get any sort of reaction, and as I press the power button multiple times the problem occurs.
    It does this multiple times in one setting, varying from once all the way to 10 or 15 times until it actually turns on. The thing is, it ALWAYS turns on eventually. I took it to the Apple Store while it was still in warranty (several times, actually) and they weren't able to find anything wrong. Honestly they thought I was making it up even when I had several people with me agree that they saw the problem happen. I left it at the Apple Store for repair and they did tests, reinstalled the software, but once I took it home the problem still remained. Because they didn't find anything and didn't seem adamant that anything was wrong, I just felt frustrated and left it, since the computer still functions fine otherwise. Now my computer is out of warranty but the problem is becoming more of a pest now that I'm in college. I do everything on it and I'm worried that one day it won't turn on. I took it to the Apple Store again and they told me they couldn't do anything for me now since warranty is out, despite the fact I took it to them expecting good service while it was in warranty and they did absolutely nothing!
    I just need some answers. Whether a self fix or from Apple. I feel that Apple should help me solve this problem since they failed to do so before. I'm only 6 months out of warranty, too.
    My computer has all the latest firmware and software, running on Lion Mac OS X 10.7.5

    BUMP.
    I actually showed this to Apple geniuses when I took my computer to the apple store, and it's still here. In console it says:
    kernel[0]: Previous Shutdown Cause: -128
    I don't know if that's related or not, but maybe helps?
