2010 MacBook Pro continually freezing

Have been to the Genius Bar twice and still no resolution.  About 20 days ago the computer started freezing and after following guidance on these forums I reset the RAM etc to no avail.  Off to genius who wiped computer and reloaded old operating system having checked hardware.  Therefore suggested data corruption.  Recovered data from time machine and problem persisted.  Back to genius who wiped HD and reloaded OS as mavericks and advised not to transfer data! which I haven't.  System still freezes when on safari - appears to be not connecting well to the wi-fi when other devices are fine.  Out of ideas, thoughts please.

It might be the WiFi router you have has a firmware not compatible with the WiFi on the computer, or the ethernet on your computer.    What hardware are you using to connect to the internet?  Are there any other attachments other than power to your computer?

  • My Mid-2010 MacBook Pro continually crashes on Mavericks

    Since upgrading to Mavericks I have consistently had my MacBook Pro crash due to what looks like a some kind of panic. Any ideas? Here are the details I get when rebooted:

    You've got a bad discrete graphics circuit. It's very common on the mid-2010's. There was a program in place to replace the motherboards within 3 years of purchase, and some users have reported being able to get it fixed outside that window for free. You need to make a Genius Bar appointment.

  • MacBook Pro continually freezes

    Hi,
    For the last month or so, my laptop has been continually freezing at random instances. Upon freezing, all applications become inaccessible and the force quit does not work, thus I have to switch of the laptop manually via the power button.
    From looking around this forum I have seen similar issues followed by requests for a screenshot of the Console at the time of freezing. Here is mine: http://oi41.tinypic.com/2mfkdjm.jpg
    It appears that Sophos may be causing the problem. I therefore uninstalled the app, but there is still a Sophos icon in the menu bar. How do I remove this and should this not have gone when the app was uninstalled?
    Thanks!

    Welcome to Apple Support Communities
    You didn't uninstall Sophos properly. Install it again and follow the proper steps to uninstall the application > http://www.sophos.com/es-es/support/knowledgebase/119182.aspx
    OS X has got its own security systems, so you don't need any antivirus. See > http://www.thesafemac.com/mmg

  • My mid 2010 macbook pro keeps freezing/crashing every time I try and play a game. Any help?

    Every time I try and play either WoW or The Sims, my mac goes to black screen, or black screen and repeating last second of noise it was playing. I haven't upgraded to Lion and am still using Snow Leopard(??). I am by no means the most tech savvy girl in the world, but would appreciate any help, as this is driving me insane!! Thanks!!!

    I don't know if it would help, but this is all the whoo haa from the last panic report thing. (about 5ish minutes ago)
    I don't really know what any of it means, but if someone could help me decipher and tell me if there's anything I can do, I would be super grateful. (before I go into apple, that is)

  • 2010 Macbook pro freezes a lot, but mouse still moves. It unfreezes if you wait. It also hard crashes... Also, weird lines and screen flashes.

    I have a 2010 Macbook pro running snow leopard (Mac OS 10.6.8).  First off, this has been the worst computer I've ever owned or have heard of someone having, Mac or PC.  There hasn't been a time where something hasn't been wrong.  I'm going to list my specs, my current problems and maybe list previous problems after that.  Any advice or suggestions would be great.  My brother works for apple out in Cali and I've been sending him crash and bug reports and he can't seem to figure out what's going on.
    Specs:
    2010 Macbook Pro (Mac OSX 10.6.8)
    Processor: 2.66 GHz Intel Core i7
    Memory: 8 GB 1067 MHz DDR3
    Graphics Cards: Intel HD Graphics (288 VRAM) and a NVIDIA GeForce GT 330M (512 VRAM)
    (if you want more info, just ask)
    To start things off, my computer hard crashes at random points playing basically any game.  StarCraft 2 (when I could play the game prior to Blizzard patching my OS out of the minimum requirements), League of Legends, MineCraft and others all crash while in use.  My computer screen suddenly flashes white and then to black and whatever audio may have been playing in the past second of gameplay is thrown into a constant loop.  The screen is solid black with no mouse and there is no keyboard functionality.  The only thing I can do is hold down the power button.  I first started noticing this problem back when StarCraft 2 Heart of the Swarm came out.  I would crash every 4 or 5 games in this way.  Since that was happening I resorted to playing other games such as League of Legends.  I wasn't having any trouble at all, but gradually it started to have the hard crashing issues.  Initially every handful of games, now it crashes in roughly 50% of the games I play.  This happens while I have NO other applications open and this has happened even after a complete restart with only 2 things opening at startup.  League started crashing in this way after I brought my computer in to have a fan replaced. 
    Another thing which has started happening since I had my fan replaced at the apple store: My computer has become very sluggish at times and my computer freezes in another way.  Many times a day, I will find I click on something in an application and the entire computer locks up.  There's no spinning beachball.  There's no movement of any sort on the screen and there is no button functionality, but I can move the mouse.  Clicking does nothing.  This sort of freeze lasts for about 30 seconds up to 5 or 6 minutes or so.  After that, it suddenly just decides to work again.  I can tell when it unfreezes because the clock in the corner jumps to the correct time.  This has happened frequently while using Google Chrome, Firefox and Safari.  It also happened while trying to use Skype.  It was freezing the most when facebook or youtube has been open, but it happens without that happening as well.  One of the first times I noticed it, earlier this year, I was searching for work and tried to go to this website: http://www.nhab.org/ (looking for a job).  It froze my computer as I described above (and I didn't know it would unfreeze after several minutes, so I thought my computer was completely frozen). I restarted, went to the same website and it froze again.  I did this a third time and it froze again, so I restarted again.  On the fourth try, it loaded.  The frequency of this problem is ridiculous.  I actually decided to delete Google Chrome from my computer (and its support files) since my computer would freeze the most often with Chrome (though I used Chrome mostly for youtube and watching tv shows online).  Almost instantly after deleting Chrome, my computer was running significantly faster.  things loaded quicker in other browsers and aplications loaded smoother.  My text no longer lagged when typing in facebook...  It hasn't solved the freezing, though the freezing tends to last less time now.
    Another thing that happens, which I am not sure is normal: When my computer is booting, after the grey screen, it changes to light blue.  During this light blue time, often times white horizontal centimeter to inch wide bars will flash across the screen near the top.  This also happens on shutting down.  I also noticed that when it shuts down the screen doesn't just shut off.  The screen flickers quick for up to a second and then it is off.  It doesn't just turn off.
    My computer has also occassionally flashed for a brief fraction of a second, to the blue start up color and back to whatever I am doing.
    Those are all issues I am having right now and I am beginning to wonder if this several thousand dollar computer is capable of doing much more than just writing text..
    Prior issues I have had:
    Right from the start, I have had major graphical issues which I showed to the people at the apple store and they reinstalled flash, but they really didn't know what was going on.  These glitches would tiles previous graphical things I had done in an artistic mozaic across my desktop, replacing my background image with broken mozaics.  It's hard to explain without showing, so here are 2 screenshots from it:
    The people at the store thought it was just flash... but I don't understand how that could be flash.  I would have to flip through different desktop backgrounds I used to make it go away.  After it doing this for 2 years, it has only happened once since then and not very badly..
    Another issue I had: The battery on my laptop just about exploded... I woke up one morning with my laptop sitting on my night stand as usual, but there was a small crack across part of my trackpad.  I was scared because I thought I must have done something... I went to the bathroom, took a shower and when I came back the crack was farther across the trackpad.  I had breakfast, came upstairs and my trackpad had 1 crack across the whole thing with multiple mini cracks going in every direction from it.  After telling my brother what was going on, he quickly said that it was the battery and to take it to a store.  I took it to the store and showed them what was happening and they very quickly took it out back and I quote "threw the battery in a firesafe immediately" because when they opened the laptop it started to quickly expand.  This ended up cracking my trackpad as well as bending the bottom of the body on the laptop.  All had to be replaced...
    Then I had the fan sounding like a weedwacker, so I had it replaced a couple months ago and a couple months ago is when the freezing began, the computer started running slowly and all games crash the computer.
    I have had a lot of things go wrong, not a lot of things go right and I'm really frustrated.  Can anyone tell me how to get my computer to stop freezing or how to make it stop hard crashing during any of the games I play?
    Basically, what I have done so far is reset the PRAM I think?  I held command + option + P + R on start up and had it chime 3 or 4 times.  Other than that, I don't know what to do.... suggestions?

    I just wanted to follow this up by saying that you were entirely correct in your diagnosis of the situation.  My computer did have the faulty part you linked to.  I brought my laptop in and specifically told them to run that test, had it fail and then argued with the person at the genius bar and the manager.  Eventually they offered to have it sent out and have everything replaced for free of charge.  They did so mainly because I had complained about graphical issues almost every other time I had come in with problems and no one ran the test.  They should have caught this problem during my warranty, but they didn't, even though I mentioned the problem.
    Anyhow, after having the part replaced, I haven't had my computer crash a single time since, or had many of the issues mentioned above.  I've never had this experience before.  Even brand new, I got occasional crashes.  Hopefully this new trend continues.
    I do find that web browsing is still incredibly slow.  Web browsers just chug along at a slow pace, even though I have great internet speed.  Maybe I'll try just deleting my web browsers and reinstalling them...
    Anyhow, thank you for your help and knowledge Clinton.

  • Mid-2010 MacBook Pro: freezing and spinning wheel

    Hi there,
    I have a mid-2010 MacBook Pro (I know, old) that's been in very good condition. I upgraded my OS to Mavericks in May, which is when it started being slow and crashing/freezing around twice a week. For example, just doing normal things like surfing the web or checking the Airport or battery life will suddenly freeze the cursor which will then turn into the spinning wheel of death. Sometimes I can wait it out if it's a few minutes but sometimes I have to manually turn off the computer and then turn it back on when it's been hours of no change or improvement. I know it's probably best to downgrade back to Snow Leopard but I'd really like to keep my OS. Are there other things I can do to optimize my Mac? I've tried keeping fewer files on the desktop and emptying out the trash often and it seemed to help for a while. Other suggestions?
    Thanks for reading!

    Wow, that post looks like a mess...I will try to make it more readable.
    Thanks for your reply. I had to wait a few days for the problem to crop up again. I followed your instructions to the best of my ability. The thing is that the problem (i.e. freezing and spinning wheel) happened at 8:19 and the closest messages in the Console were are time stamped 8:17 and 8:25. So I will put them here for you to look at if you don't mind:

    I hope this is not too much text and I hope it makes some sense. The problem happened while I was closing a tab on Chrome, which wasn't anything sketchy, just Facebook, and nothing too unmanagable (it was the only application active). Thanks for your help!

  • My macbook pro keeps freezing with vertical lines on the screen

    I have a 2010 macbook pro that has worked wonderfully until now.  As of late it keeps freezing with vertical lines across the screen.  To me this indicates a hardware problem, but I ran a diagnostic (restarted while holding D) and it didn't find any errors.  It seems that it happens when I move or bump my macbook, leading me to think it may possibly be a disk problem, but I'm not sure how to check this.  Anybody else ever have this problem or could suggest a fix for it?

    You can try a pram reset, which might help with the display, but the bumoing thing is what concerns me.
    PRAM reset:
    Power down, power back up and hold the following keys before the start up chime.
    option, command, P, R,(no commas) continue to hold these keys till you hear the start up chime 2 times then release.
    Reboot see if this helps, the bumping part scares me.
    Hope this helps

  • 2010 MacBook Pro - something is wrong (it is very slow)

    Hi folks!
    I am using 2010 MacBook Pro, 2.66 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3...
    It is 320 GB and 90 GB free.
    Computer started to act crazy 2 months ago. But now the symptoms started to be intolerable.
    It takes so long during start up, also even it is on completely, every time I opened first program (even after 10 minutes) it freezes for some time and then continue to work. Almost every program open very late, and when I click the icon on the dock to quit the program for most of the programs, computer freezes and then says application not responding, therefore I always click force quit.
    Sometime even if I dont push the computer so much, it freezes and quits the program that I am using at that time. And sometimes (let's say I want to open activity monitor under utilities), I click application folder on the dock, then click utilities folder but nothing happens and it does not open the folder, then I again try to click Application folder, then utilities but again it does not open the folder, after 3 or 4 times, it open the utilities folder then I am able to click activity monitor in the folder, and it opens it.
    Also I started to hear hard drive sound a while ago, just like external harddiscs that seems will be broken soon. In case, I back up it with time machine...
    Additionally, is it normal Google Chrome uses so many memory? When I watch a video in Chrome, everything becomes even more slow.
    And last thing, when I use skype, camera quits spontaneously, sometimes when I click start my camera, it starts, sometimes it says camera is used by another application and it does not start it. Also, skype just started to become (switches between) offline and online spontaneously.
    What is wrong with my computer? Should I format it?

    Bootcamp is installed by default but if you have not touched bootcamp to install your Windows partition, you shouldn't encounter the problem I was describing.
    As for Parallels - just thinking out loud. When you talk about "Running chrome", are you actually running chrome on Mac or are you running chrome in Windows (Parallels).
    Also, do you keep your Parallels running all the time when you're not actually using it?

  • How to get bootcamp to install from USB on Mid 2010 Macbook Pro in Mavericks

    Ok, finally ran into my first problem with Mavericks. It's a doozy. Please if anyone has any advice, let me know.
    My bootcamp partition was acting a little buggy. I also wanted to make the partition larger, so I went ahead and erased it, made a larger partition and was getting ready to install windows 7.
    Unfortunately, little to my knowledge, bootcamp assistant is programmed to not allow installation of Windows via USB if your computer had an optical drive in it's factory delivered form.
    I have removed my optical drive in favor of a second hard drive and encased my original superdrive into an External USB hub.
    There apparently used to be a solution involving editing the plist.info text document to allow USB installation. However, as of MAVERICKS, this document is now locked and unable to be edited.
    I was running windows 7 fine until I scrapped it, and now I have no way to re-install windows short of going through a laborious process of re-installing my optical drive into my laptop, installing, and then re-installing my hard drive back in. The only reason is due to a software bias for my series of laptop because it "used to have" an optical drive.
    Does anyone know of any way that I can bypass this issue to get Windows Re-installed to a bootcamp partition on a mid-2010 macbook pro without using the optical drive?
    Thanks in advance!

    Remove the Boot Camp partition only with Boot Camp Assistant, not with Disk Utility.
    Install or Reinstall OS X from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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.
    Erase the hard drive:
      1. Select Disk Utility from the main menu and click on the Continue button.
      2. After DU loads select your startup volume (usually Macintosh HD) from the
          left side list. Click on the Erase tab in the DU main window.
      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
          the Security button and set the Zero Data option to one-pass. Click on
          the Erase button and wait until the process has completed.
      4. Quit DU and return to the main menu.
    Reinstall OS X: Select Reinstall OS X and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
               because it is three times faster than wireless.

  • How's your Mid 2010 MacBook Pro doing after changing logic board due to BSoD?

    After this very long discussion:
    https://discussions.apple.com/message/15665312#15665312
    In which a lot of people had BSoD problems after upgrading to Lion, and then have solved the issue by having the logic board replaced, I'd like to ask, specially for those who have done it earlier, a few months ago or so: did you have any problem with your 2010 MacBook Pro 15" since then?
    I'd like to know it because, by reading that thread, I have reasons to believe that the problem may arise again after some time.
    I had the same issue with my MBP, but I'm still on Snow Leopard. I had the logic board replaced more than once (actually 3 times), and everything is ok since then.
    Now I've been pushed to upgrade to Lion so that I can continue using iCloud. So i'd like to know what are my chances of going into that nightmare again.
    Any info will be appreciated.

    Greetings,
    I've never heard of this issue - I have two MBP Mid 2010, and both are running Lion with all updates, and there are no issues of any kind. One of the graphic shops I work with has 15 Mid 2010 MBP, all running Lion, and there are no isues with them.
    We use a lot of high end software, but no games, of course, just business and graphics apps. There have been no issues with Mail, Calendars, Addressbooks, etc, except for wanting a few more features, here and there,
    which we will get in time.
    Bad apps are the usual culprit, when there are problems with Macs, and they are not always easy to locate, so I just reload from scratch, and thet will usualy fix a lot of ills, if the normal troubleshooting tools don't resolve the problem. Fortunately we have had very very few issues with our Macs going back to the late 90s, and earlier - they just work, and work.
    Try a reload if you have troubles.
    Cheers,
    M.

  • Mid-2010 MacBook Pro seemingly fried by Mavericks

    I have a mid-2010 MacBook Pro that I installed Mavericks onto a couple of days after general release. Everything was fine with it for a week or so, and then I started to notice a couple of weird errors crop up - I had an error come up on iTunes (I think the error code was 13024) and apps would start to not open. I thought it might need a restart, so I rebooted. On restart my computer then hung on the grey startup screen with the loading wheel spinning perenially. After 10 attempts, I tried every alternate startup key input I could think of to try and get my computer in action (Reset NVRAM, Safe Boot, etc.) The first one to 'work' was Startup Manager by pressing Option. I opened Recovery Mode and tried verifying disk permissions. This threw up a TON of errors. On repairing, they all gave a me Error-22. Repair Disk didn't work either. I then tried restarting again to see if anything had been changed to boot as usual. Again, nothing.
    Next I pressed D on startup to run an AHT. This actually successfully booted to my desktop and could explore Finder and see my files etc. No applications would open and Quick Look would not let me view any files. System Preferences would also not let me launch any preference panes. Pretty much anything I clicked yielded a dialog box with a message along the lines of "Unapproved caller: SecurityAgent may only be invoked by Apple software."
    My whole system froze up on the rainbow wheel after I had to relaunch Finder from the Force Quit menu after testing Quick Look. Now when I boot into the Startup Manager neither my hard drive or the recovery drive are visible, and I only have the option to run Internet Recovery (where I am writing this post from). Normal startup just gives me a flashing folder icon with a question mark in it. I'm fairly sure Mavericks has totally fried my hard drive. Does anyone know if there's anything I can do about this or has had something similar happen to them?

    Dude i had same problem and also running same hardware as yours, i complety fomated my HDD and reinstalled everything from scratch. That did not help me, i thought it could be my HDD getting corrupted (reason why i thought that is becuase whenever "unapproved caller" showed up at same time everything on my HDD went read only mode). Hence i replaced HDD and put in new one, i dont get unapproved caller anymore.
    But there is still a problem somewhere, becuase my MBP freezes and HDD goes to read only mode, the only solution is to restart my mac sometimes multiple times.
    I think both these events are mutually exculsive.
    I have been troubled with this for about week now and very much gave up all hopes on my MBP.

  • Mid-2010 Macbook Pro White Screen of Death?

    Hi all,
    I have a Mid- 2010 Macbook Pro, running 10.8.2 that, when booting, sounds the Startup Chime but no Apple logo appears, just a white screen.  I'm in IT so I've done several things, but nothing has worked and I couldn't find a previous discussion that was similar to mine.
    Here's what I've done so far:
    - Changed hard drives
    - reseated RAM
    - Unplugged Battery
    - Reset the PRAM
    - Tried to boot from CD using CTRL- C
    - Tried Recovery boot using CTRL- R
    Anything else I could try?  I keep thinking it may have something to do with the Time Change, but that seems a little weird to me if that's the cause.  It worked fine late last night and then it did this in the morning (after the time change).
    Thanks for any help you can give!

    Hi sanjampet,
    Tried the SMC reset, safe boot, CD boot, and Recovery boot all with no luck.  Not sure why it's going on, but it's looking more and more like a hardware issue to me.  It's a white screen (instead of a grey screen), so I'm worried that it's something with it.  I'm going to try and see if I can remote into it using Screen Sharing to see if it's something with the display.
    My wife used it last and she told me that it was slow on the internet with the mouse freezing up, so she held down the power to turn it off then it came up with the white screen which hasn't come back on since.  I'm using an 3rd party SSD hard drive and replaced it with another SATA hard drive, but it didn't help.
    Thanks,
    JN

  • Mid 2010 Macbook Pro, all application crash.

    I have a mid-2010 MacBook Pro, which the original version was 10.6, now upgraded to maverick. I had no problems with it until 2 days ago it started.
    EVERYTHING crashed. Safari. Firefox. Skype. iTunes. EVEN finder. It only crash if i type something in the search bar. Like in safari, the website bar, if i type there something, it will freeze for 1 sec and crash. Same with firefox. Finder, if i type something in file searcher bar, it crash, causing the icons to disappear, and be back in 2 seconds. Even my games crash often. Like 30s - 2 hours each crash. I am now desperate because I can't use my Mac without typing anything. Also, top-right corner, where the wifi and things there has moved to the right, and cannot be seen expect for my hamachi icon there. What the fck is going on.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Mid-2010 Macbook Pro - Sudden Issues everywhere

    Ok, so I've got a Mid-2010 Macbook Pro and just before Christmas all of a sudden issues just popped up everywhere. I'll give you a rundown of what all i've seen and what all I've done since.
    So I start getting a message something like
    - AppleSecurity - Unauthorized caller ...popping up intermittently. And then,
    - Firefox, once you shut the window down you couldn't get open again, and when you quit the app the computer seemed to freeze
    - ITunes wouldnt open
    - App Store wouldnt open
    - Safari would only open some webpages
    - Steam worked 10% of the time.
    - Powerpoint and Word would crash or not save etc.
    - I had to push the button to restart to get the thing working again and from time to time it would freeze or crash shutdown at the grey screen.
    - I kept getting small indications that the memory was full.
    - Cant shut down or restart without holding the button
    So I deleted stuff, generally cleaned up unneeded files etc. ... Same problems. I eventually got so exasperated that I just stuck everything I needed on a flash drive and wiped the user and started a new one.
    Same problems but slightly better.... So at this point I go into the Apple Store and go to the Genius bar - The guy wipes runs a check on my hard drive and everything ticks the boxes barring battery which is at 74% roughly. Then he wipes everything off to a factory restart, updates it, then hands it back.
    I get it back home and I have issues even setting up the user as if it was a new macbook. I have untick all the set time zone and network stuff to get it to work.
    I get it back going and ... still problems... but slightly better. But I cant update flash, steam crashes, sometimes again things dont work. Safari sometimes doesnt open some webpages and I have to restart to get things to get working again.
    Also, things seem to be a little better when I'm using the universities internet as opposed to the one in my flat.
    SO...! Back into the Apple Store, Genius Bar, he runs a full check on the drive because he seen some I/O errors in the console. AND.. everything passes. He runs a full daignostic and still can't figure it out. He says he seen some weird messages about Steam causing problems in the console but that was it, which I dont think could be the problem because I was getting problems before I even reinstalled it after the factory wipe/reset. The network causing problems maybe?
    What do I do people? No-one at the Apple Store can pinpoint whats going on?! I really want to get this fixed because I need this for uni and I can't afford a new one
    Please Help!

    poikkeus1,
    After getting a "properly" functioning LB, the temps are much lower than that, even when beating onit doing live recording. idle 25-30 degrees max, beating it with a "pile of inputs" recording 65-70
    The first machine i spent over 4 hours with a senior engineer doing an ARA, it was like someone took a shotgun and blasted the data all over the place.
    I switched machines (after 30 days, which would say they knew they had an issue)
    Second time temps off the map, and unexplainable "bizzare" behavior. (random)
    second time same deal, all over the place.
    Now everything seems happy, for months now. (I hope I just did not jinx myself)
    It sure seems that would be the place to look, hence you should ask for the flat rate repair.
    Best

  • My mid 2010 MacBook Pro loses network connectivity

    I have four mac computers running on our home network.  My mid 2010 MacBook Pro has become notorious for losing network connectivity with the other computers.  It maintains it's internet connectivity consistently, but it's ability to see and connect with the other computers on the local network is finicky at best.  The other three computers (2008 iMac, 2012 iMac, 2012 MacBook Pro) all connect to our Actiontec MI424WR Fios router via ethernet, whereas the mid 2010 MacBook Pro connects via WiFi.
    If anyone could please help me troubleshoot the issue, that'd be much appreciated.
    Sincerely.

    Back up all data before making any changes.
    Step 1
    Take all the applicable steps in this support article.  
    Step 2
    If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
    Step 3
    If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
    From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
    If the application called "Bluetooth Setup Assistant" is running, quit it.
    Step 4
    This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.
    Triple-click the line below on this page to select it:
    /Library/Preferences/SystemConfiguration
    Right-click or control-click the highlighted line and select
    Services ▹ Reveal
    from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
    Reset the System Management Controller.
    Step 5
    Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present. 
    Keeping your confidential data secure during hardware repair
    *An SSD doesn't need to be zeroed.
