2011 macbook rebooting randomly

My macbook (Yosemite, 16Gb Ram) is rebooting randomly. It happens ever 45 minutes or so and it restarts itself even after being shut down normally. Any ideas?

Brand new 2011 MacBook Pro Randomly freezing

Hi,
Im a bit concerned I have just got a BRAND NEW MacBook Pro 2011 and already I have had 4-5 random freezes where i have had to hold down the power button to bring it back to life!!
These have happend as i said just randomly, for example i lifted the lid to wake it from sleep mode and it just frooze on me, became totally unresponsive??
Another example was when i went to paste a url using cmd-v and it frooze on me??
I'm a bit dissapointed as I have just switched from windows PC's because I had had enough of that sort of thing and believed these where solid machines with very little issues comapred to a windows system!! and for 2k I don't exect it to freeze especially within a week!!
I'm hoping its down to software issues to which a software or OSx update will solve.
Any Ideas?

Hello, I have had very similar problems but with the MBP not even registering that a charger is plugged in (no light coming on and no change to the battery symbol).
I had a mid 2010 model that was sent in 4 times to be fixed, with no change, followed by the unit being replaced altogether with the latest 2011 model, only to find the issue persists (the charger was replaced early on as well).
The only retaining factor is the Lion software which forums have highlighted has effected charging when individuals have upgraded.
It is appalling that a company like Apple have not taken steps to address these issues and will go as far as to replace all components TWICE in one Laptop, as well as give out a new Laptop, without tackling the real problem.
Appalled and ultimately very disappointed.

After upgrading to yosemite my macbook pro late 2011 does a random sound from time to time.

After upgrading to yosemite my macbook pro late 2011 does a random sound from time to time. Its completely random and i already checked all apps in use and its not from them.

Sounds like Notifications app.
Maybe some other app. In SystemPreferences->Users&Groups->LoginItems tab: remove all entries with the minus sign underneath. This will not uninstall anything, you have to start those apps by hand now. Restart.
Still there?
Yes: Restart again while holding the shift key, this will start the mac in SafeMode: only the necessary items are loaded to run.
Still there?
Yes: Make an etrecheck list and post it here.
No: Restart, put the items in the LoginItems back, one by one, restart after each entry, and you will find the "culprit"
Please report accordingly. I will be back in 24 hours.

Early 2011 MBP 13 random reboots (no Kernel Panic logged)

Hi,
Problem Description:
My MacBook Pro randomly reboots at least 1-2 times a day. I cannot find a kernel log because each restart is a double one.
Let me explain the problem further : 1. Im doing something (nothing specific..no specific app) on the mac 2. The screen freezes and becomes unresponsive ( I know a reboot is coming)
3. I get the gray screen which says "Your computer restarted because of a problem..." ...this is followed by the white screen with the apple sign..it loads for a few seconds and it reboots AGAIN..this time i hear the chime...loads into the OS normally ...works until i either shut it down / put it to sleep / another random restart (varies from 1 hour to 6 hours )
Things I've tried :
SMC / PRAM reset
Erase Drive and TimeMachine Restore
Apple Hardware Tests / Diagnostics all pass
Verify / Repair permissions / disk (did this a million times)
Reindexed Spotlight
Erased Drive and did a clean install and MIGRATED files from TimeMachine
Safe Mode ( THIS did not have random reboots...also fyi ..i didn't try this for long)
Logs Data:
Since I don't have the .panic files. I am pasting a chunk of the log before and after the PROBLEM.

MacBook Pro 13 (MBP 8,1 random restarts)

My Early 2011 Macbook Pro Continues to shut off at random

I own an early 2011 Macbook Pro, 4GB RAM, intel 3000 384mb graphics, 250gb SATA hd. I now have OS X 10.8.2 and my macbook randomly shuts off and its not just once or twice a day. It is more along the lines of over 20 times a day. Can somebody give me some advice to resolve this issue? I used mackeeper and ran every scan and I went to disk utility and repaired the drive. I don't know what else i could possibly do. This issue is making me wish i never bought this mac. The macbook is great and all but now i can't even use it because it shuts off at random. I can't enjoy the macbook if i have to use it in fear that it will shut off at any moment. Can someone please help me with this issue quickly?

If you have Apple Care or are still under warranty, give them a call and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Sorry ... I read but was unfortunately distracted from your original post. You have a system that came with Lion. The Lion that is on your system is only for your computer and cannot be downloaded from the app store again because you never purchased it officially through the App Store.
Try this for making an external USB/DVD copy of Recovery on an external disk. internet is still required for reinstall, though, I believe: http://support.apple.com/kb/HT4848. But at least you have a separate Recovery Partition if you ever need a fully new and empty internal disk.
Your assumption is incorrect. Although he may not be able to download it from the App store he can download it directly for the Apple servers using the recovery partition on his original drive.
All you have to do is start the install routine and then point the install to an external hard drive. Once the download is finished the computer will reboot to start the install. At that reboot disconnect the external drive so the install can not start. Boot the computer back into the OS on the internal hard drive, which is what will happen automatically once the external drive is disconnected. Then connect the external and copy the files from it that were downloaded. Right click on that downloaded package file and select Show contents. In the contents of that package is a file called InstallESD.DMG. Copy that file out of the package and burn it down to a DVD or USB thumb drive and you now have the Full Lion Installer. I have several of them laying around on different hard drives and 2 USB thumb drives which I have used to reinstall Lion on my 15" MBP.
Sorry OP I should of just typed this out in my first post.

Early 2011 Macbook Pro - Black screen at random

I have an early 2011 Macbook Pro, running Mac OS X (10.7.5). Seemingly at random, the screen will go black and the only way to get it back is to hold the power button down. When it turns back on, everything is running as normal. It's been happening more and more frequently, so I'm wondering is this a problem I can fix on my own? Can it be fixed or is it just a glitch I should just deal with?
(Please explain everything to me as if I were a 5-year-old)

Early 2011 15" Macbook Pro.
Add me to the long list of customers experiencing display issues. HUGE problems with a blank screen when waking from sleep and difficulty starting up (video glitches & hi fan speed). After about 6 months and 2 genius bar visits I finally did a complete HD wipe/clean install of Mavericks with all of the default settings.
The situation has improved only slightly overall, but at first things were great. I was confident I had it licked.
As I restored apps & profile settings things start to get wonky. The last install I did was Picasa (I thought this app was the culprit before the wipe). I successfully restored my Picasa settings and all was fine. I even closed the lid and when I opened it the next day the screen came right back on. Then I tried to sync my iPhone and BAM! Screen goes out and the system is hung (no response to keystrokes or sound events).
Power button shutdown.
Restarted and the Macbook hung as the previously opened apps reopened.
Power button shutdown again.
Restart this time was normal and everything opened just fine. The console logs show NOTHING indicate any issues or that the machine experienced a kernel panic or anything like that.
It's been 1 whopping 36 hours since my clean install and I've already crashed twice.
But now I use my Macbook with anxiety as I never know when it's going to crap out again. Maybe it's time I switch back to Linux on an inexpensive wintel laptop as I won't buy another Apple laptop if this is the what I should expect from a $2000 machine.
Incidently, I also have a 2010 MB pro which had dispaly issues and Apple replaced the logic board at no cost (out of warranty) as part of a replacement program. I've seen MANY forum posts suggesting that Apple should step up and provide the same level of service for the Early 2011 MB Pros... I tend to agree.

Random shutdown 2011 macbook pro

My Early 2011 Macbook Pro keeps randomly turning off suddenly. The battery is no where near empty and is still stated to be in good "health." Does anyone have idea what the problem could be?

I'd like to know the answer to this too, my 2008 model has been doing it also. I am about to install a new SSD, back up and refresh everything.
I take it you're working in audio?

Macbook air (11", mid 2011) turns off randomly

My macbook air 11" (mid 2011) turns off randomly. Sometimes, in the middle of something a black screen. After a few seconds it starts up again, on using a key. It restarts in the application I worked on before. Strange!

Do you have put hard drive to sleep when possible checked? Try unchecking it.Have you tried repairing permissions in utilities? You could also do a pram reset. Command/Option/P/R keys at startup for three chimes.

2011s MacBook Pro won't install Yosemite neither reboot or boot into recovery mode.

Hello everyone, I've searched all around the web and didn't find a solution.
Sorry about my english, btw, I'm from Brasil lol!
I have a 2011s MacBook Pro, used to run Snow Leopard until 2 days ago, when I downloaded Yosemite and restarted the computer to run the installation.
During the process, it stopped at 22%, and said: FILE SYSTEM VERIFY OR REPAIR FAILED.
I tried to reboot on Macintosh HD as usual, but it's not possible, I can't unmount the HD to repair it, can't erase it and I'm a little desperate.
I have a good backup of important files on an external drive, so the best solution for me would be to format the HD again, with the Yosemite image which appears to be running at startup.
Command+ anything at startup doesn't work, probably because the Yosemite install is trying to run...
Any suggestions???
Thank you!

Hey Vince,
I have the same or similar issue. Please forgive my English, as I attended American Public schools
So last night, my MacBook Pro told me hey you want to download this free and amazing new OS called Yosemite?
(I'm adding to your post to hopefully grab more attention and then maybe grab a solution from someone out there..)
I thought yea, no, maybe, okay it's free, they say it is amazing-- why not?!?
So I downloaded and clicked okay to restart and install the new OS.......but it won't install the OS and I get stuck here on this screen.
I have tried restarting about 10 ties. I have tried quitting the install but it won't allow me to boot from Mac HD or my time capsule HD. I tried going into the menu options above but it won't let me repair or reboot or anything to get my MacBook to work again.
It is pretty frustrating. I went from having a working MacBook Pro to having a nightlight.
Vince- if you get a solution or a fix, Please let me know.
Thanks
john

Macbook pro turns off and reboots randomly

Hi I need help My 2010 unibody Macbook Pro is driving me nutz !!! Does anyone have any idea WHAT would cause my 2010 Macbook Pro to shut off and reboot randomly all by itself ? I took it to a computer storre for repair they placed the RAM and charged me 126.00 yet its still happening not as frequently but it's not fixed. Grateful for any help you can give.

Hello sweetbrandigirl2004,
Based on your post it seems your computer is shutting down at random. That does sound troublesome. After your computer shuts down, do you see any messages or errors displayed? The following article offers some troubleshooting steps you may want to explore:

i've tried reinstalling os, updating, resetting smc/pram/nvram
macbook will randomly shut off, sometimes few minutes into turning it on or hour or 2 of using it, its random
it'll shut off with the charger connected as well
it'll also shut off when using the battery, even when its around 90% charged.
Once it shuts off the battery indicator will show nothing but once pluged in to the charger and reboot, the indicator will show plenty of charge
is there something wrong with the battery or connection?
here is my battery log

what is your Full Charge Capacity? you can find it right by the cycle count, whats the status or condition of the battery?
Does it shut all the way off or is it not waking from sleep???

Mid 2011 Macbook Air Painfully slow.

Mid 2011 Macbook Air Painfully slow.
Hey everyone. I am writing about my 13 inch Mid 2011 Macbook Air.
Recently it has been extremely slow and on occasion has not started up.
I have reset the PRAM and SMC already, yet it is still very slow. I have a couple theories about what might have caused it, are they plausible?
Theory 1: It’s a software problem. I tried to upgrade to 10.8.2 but halfway through the upgrade the computer restarted and somehow I was still on 10.8.1. For fear of a big issue happening I didn’t try to upgrade again. Perhaps it is a flaw in Apple’s software update?
The important thing to note about this update is that I tried to install 10.8.2 around a month or two weeks BEFORE I started having problems. So if these issues were due to 10.8.2’s failed update then it certainly was a delayed reaction.
I would of course like to update to 10.8.2 BUT as my computer is acting EXTREMELY slow and having trouble turning on occasionally I am worried the software update will completely brick the machine. Is that possible? Should I actually finish through with the software update?
Theory 2: It was an electricity problem.
The computer died when I was sitting at a café plugged into their wall sockets. A few days later when I came back to the same spot with my old macbook which is now being used in lieu of the Air it suddenly turned black for a little while. Sensing it might be an electricity surge or something with their system I unplugged the cable. I am not sure if that was paranoia though.
Can an electricity surge or a bad outlet fry a computer? Can it fry the ram so the computer is extremely slow? Does that theory hold any water?
Thanks for your help diagnosing this problem.
All the best.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Copy or drag — do not type — the line below into the Terminal window, then press return:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.) You can omit the final line ending in “$”.
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}'
This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}'
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.

My mid-2011 MacBook Air bricks itself after 10.7.2 update

I have a new MacBook Air (11") that was working just great, until today. Today, I used Software Update to install the updates, which included 10.7.2 as well as the recue partition update.
I did everything you're supposed to do, and when it rebooted, the gray screen comes up, and it shows the spinny doohickey on the bottom showing that it's working. Then, suddenly, up pops a big "no" icon (the circle with the slash through it) after about 60 seconds.
It simply doesn't do anything after that.
Hard-power-off, wait, power-on, repeat, same thing.
So I reboot with cmd-R to get the rescue partition. It works fine; I ask it to re-install Mac OS X, which then takes about 45 minutes (argh). Finally, Mac OS X is back, the machine is nicely booted up, all my files are there, everything is good.. But of course, the reinstall took me back to 10.7.1.
All I want to do is upgrade my fricking iPhone to IOS 5.0, but I can't do that without knowing I can sync which requires iCloud which of course requires 10.7.2. So I *have* to re-do the upgrade.
Back to Software Update, back to installing 10.7.2. And .. 20 minutes later .. back to bricked MacBook Air.
What a waste of my time. What a failure, Apple. I'm very very very very very unhappy that I've wasted so much time just to update my damned iPhone to IOS 5. I'm still without an update. Now I'm trying to figure out how to move my iTunes to another machine -- not nearly as obvious as it should be. ARGH. I'm going to throw this MacBook Air off the balcony in about 10 minutes. :-(
Thanks for listening.

Wow, you're right -- I can't believe it. I just really can't believe they would screw up so badly, yet when I search for "10.7.2 filevault" I don't find more than a couple of articles about it on the web (including this thread). Why on earth wouldn't Apple have put up some kind of warning about this? I can't believe it, really. It's insane.
On my newly-functional 10.7.2 MBA, I wanted to test your theory and so I turned on filevault 2 and encrypted the main disk again. It of course wanted me to reboot. So I rebooted. And *blammy* -- same error / boot failure. Wow. Also, interestingly, even on a working 10.7.2 system, you can't mount a USB drive that was encrypted using Filevault 2 encryption (in Disk Utility, e.g., as a "Mac OS X, journalled, encrypted" volume that was encrypted with DiskUtility on Lion 10.7.1). I still have a 10.7.1 machine that I will not upgrade until I can at least decrypt the disk -- but right now, Disk Utility tells me it fails decrypting the external USB disk so I'm hosed!!! ARGH.
Now, going back to the booting problem after upgrade -- for anyone's reference who's still keeping score -- you can easily recover from the booting problem with upgrading a Filevault 2 root drive: Power-cycle the machine and then hold down cmd-r to bring up the Lion Recovery application. Within Lion Recovery, choose "Disk Utility", and then click on the (as yet unmounted, still encrypted) root hard drive to select it. Then go to the File menu, and choose "Turn off encryption" for this disk. It then prompts you for the password, and if you enter it, *blammy* you're back up and running again.
In my case, the disk had only just begun encrypting so the action was instant, and then once it confirmed the disk was now decrypted, I simply chose "Restart" from the Apple menu, and I was back in business (no hairy re-installs to deal with). If this is an already-encrypted volume, presumably it'll take you a bit longer (the normal 45-minutes to 2 hours) to decrypt it. But at least no more installing software -- it'll "just work".
Maybe I'll go post a simpler version of these instructinos on the other threads, but this is the simplest fix -- just turn off filevault 2 from within Lion Recovery, basically, and that fixes the boot problems.
Apple, if you're listening, you really really really need to say something to your users so they know. Many many many MBA users are likely to have still not upgraded. You can prevent them from hating you and your products by making sure they don't screw the pooch here. Short version: Mid-2011 MacBook Airs running Filevault 2 WILL NOT BOOT after 10.7.2 update; so users should turn off Filevault2 before upgrading.

My mid 2011 MacBook Air fell off my couch onto carpet. Slowed down.

I made a post a few weeks ago about how my mid 2011 MacBook Air slowed down randomly over night. A few days later it randomly started functioning properly again. I was stoked.
Today, I was using my MacBook on the couch, when it slipped off and landed on the carpet bottom up with the lid closed.
The moment I opened it up again, it was back to being slow again.
I ran the Disk Utility, tried repairing it, it said that the hard drive 'appeared to be ok'
But yeah. I'm gonna say it's a pretty safe to assume that the drop has everything to do with the slow response time.
Would anyone happen to know what actually might have went wrong, though?

I would think a poor connection of some sort, may be a plug and socket or a soldered joint problem. I think you need to take it in for repair, I cannot think it will be software that is causing the fault, but...... you never know.
