MacBook Shutdown On Boot w/Shift Key

I just found out that I can reproduce a (not so) random shutdown 100% of the time on my MacBook. For some reason if I hold the shift key down durring boot, the MacBook shuts off every time on the screen with the apple and the spinning wheel...
I've already sent in my MacBook for repair of the random shutdown issue, and the firmware update that was also supposed to fix it is also installed... All be it since both the hardware repair and the firmware update I've had a small handful of the regular type random shutdown issues...
I filmed the pattern occuring & posted it online. It's interesting to note that it's specifically the holding of the Shift Key that's causing it, as it will boot normally otherwise...

hi,
regarding the external drive question
i would ask the question in the boot camp forum.
regarding space issues on a mbp:
i solved my space problems using the "printer repair utility" and the additional delete of some files/apps like garageband including the sounds files.
maybe "Disk Inventory X" will help you getting an overview about your disk-usage.
i hope this hints offer a small first help for you.
best regards

Macbook pro only boot with R key

I have a problem with a macbook pro .
I have snow leopard and after running onyx my computer only boot with the R key pressed , I have tried option-command-PR , reset SMC , repair permissions without success .
I have an external apple led cinema but with or without the error continues .
Any help would be appreciated.
Thanks

Why did you try booting with the R key pressed? From what I recall that key simply resets the screen settings, and shouldn't have anything to do with your system starting or not. I would remove it from the external display until we can get this resolved.
I'm wondering if it has something to do with your NVRAM. Try booting with this key sequence cmd-opt-n-v.

Macbook typing in all caps, shift key issue.

Alright, so I've been battling with this for a bit now, as I discovered to my chagrin: My macbook is now only typing in caps. Upon pressing Command + Q to try and close an application, I noticed it brought me to the "log out" prompt, suggesting the problem was a stuck shift key. I've removed both keys and checked for any particulates and they're all clean. Any ideas?

No. Sounds like you powered it backup while it was still wet. If so the damage is done. Problems will only get worst as corrosion sets in.
Suggest you take it to Apple and ask them for the cost of repair it.

USB keyboard shift keys suddenly not working

For some reason, when I woke up my MacBook Pro this morning, both shift keys on my aluminium USB keyboard were not working. I'm using the keyboard with a Magic Mouse and LED cinema display connected to my MacBook. When I hold either shift key in combination with any other key, either nothing is typed, or there will be random characters typed, occasionally.
I ran AppleJack on auto to see if there were any problems. There were a few preferences it corrected, but nothing major was wrong. I connected the keyboard to a friend's MacBook Pro, and the shift keys did not work on his machine either. Caps Lock does work. I've tried canned air. I don't remember spilling anything on it.
Any idea about what I can try to get it working, or is it broken? Thanks,
-Jeff

Try resetting the PRAM. Info here:

Macbook Pro, running 10.8.5 - can't restart but can shutdown and boot up - may have virus or malware

Needless to say I'm beyond embarrassed. I teach computer science (Middle School, private school) and have forever warned my kids to be very careful what they download; but are always "safer" with Mac OSX. Alas, maybe not. I was trying to download Google Earth a few weeks ago and got caught in that fake trap (the fake "Installer" trick) and realized way too late I'd downloaded something "else" instead of Google Earth. Pop up adware by the gazillion. My browser settings were a mess. Went in and reset them as best as I could. And for awhile, so far so good. Until I tried to launch Firefox this week; and WOW...awful. I deleted my Firefox files, went to Firefox and RE DOWNLOADED (or so I thought) a new version of Firefox, and WHAM. Hit again. I can shutdown my Macbook; I can boot it up from a cold dead start...BUT I can no longer "Restart" the computer without an annoying popup message pretending to be a wayward "Installer" wanting to "complete a download" stating if I didn't want to complete it I could 'click' Abort...well I tried but the screen froze. I've had to shutdown or do a hard reboot to get it back up again. I've checked my settings on Google Chrome; seems fine. Don't use Safari that much, but it appears to be a Firefox troll.
What should I do to troubleshoot what this is and how to be rid of it? I wish I could send you a screen shot of the pop up but alas, it freezes the screen when I try to click anything thus my Screen shot capability is nil.
I bought this Macbook Pro in April, 2013. It's my workhorse. HELP!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

8. Launch the built-in 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 and start typing the name.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

My MacBook Pro will not start up. I only get a grey screen with the spinning wheel. No blue page appears and the grey screen remains. Tried starting with the Shift key but ineffective as well.

Can't get my MacBook Pro to start up. Have shut it down several times and tried restarting but all I get is a grey screen with the spinning icon. Apple Support online suggested starting with power button followed immediately with the shift key. Same results. Also tried power button with shift key, command, and V. Black screen appeared instead with lots of data language but still no starting. This final page was suppose to result in an internal system check and restart but nothing happened and the black screen remains.Where do I go from here? Scheduled for the Genius Bar tomorrow but would like to resolve this beforehand.

You may be having a hardware problem that you cannot resolve on your own. Nevertheless...
...hold down the command and R keys whilst booting to try to get to your Recovery partition. If you can, use Disk Utility to try to Verify your boot drive (usually named "Macintosh HD" unless you've renamed it). If the verification fails, try to repair your hard drive. If everything appears to be OK, restart.
If you can't get into your Recovery partition, your problem is likely hardware related. If so, keep your appointment and see what the Apple techs have to say.

Screen stuck on gray, used shift key and my screen appears with MacBook Pro and not the recovery option. Please help

Screen stuck on gray, used shift key and my screen appears with MacBook Pro and not the recovery option. Please help!

Hi ..
Shift key boots into Safe Mode, not Recovery.
This only works on a Mac running v10.7 Lion or later.
Startup your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities to repair the startup disk and restore OS X using OS X Recovery

Why endless shutdown during booting? - Macbook Air 10.8.3 update

After updating from 10.8.2 to 10.8.3 my Macbook Air 13" mid 2012 started to shutdown during booting.
I have tried to reset the SMC and PROMs several times with no result - still shutdown during booting.
The same result when starting in "safe" mode - shutdown in the end of booting.
When booting in verbose mode the last lines befor shutdown was:
AppleLMUController::smcReadKey received error 0x84 when reading key 'MSLD'
AppleLMUController::smcReadKey received error 0x84 when reading key 'ALV0'
It's no problem using the macbook air in target mode and use as the startup disk on another macbook.
The other mac start fine and run smoothly on the system 10.8.3 on the disk from the macbook air that shutdown during booting.
Before updating there was no problem with the computor...
What to do?

Run the #12 OnyX cache clearing routine, it's a lot of stuff to do and will take awhile, but it's very through on reseting your sub-system items like it was when it came from the factory.

Left shift key of my new macbook pro retina 13 is always pressed.

My 1 month old macbook pro retina 13 inch model has a problem now. Left shift key is always pressed which results in booting to safe mode.
Currently i have overcome the issue by pressing "option" while booting and used keyremap software to disable "left shift key". Since this a temporary solution, I would like to know what would have caused the shift key to behave like this. If the key not working would have been better, but it is always in pressed state.
Please let me know what I can do to rectify this. If keyboard to be replaced, approximately how much it will cost for the same? I am looking for a positive response....
Regards,
Jibin

Hi BobRz, you are probably talking about the screen display which normaly dims during low light conditions, and that's true. but my concern is the keyboard brightness, it suppose to increase in low light conditions, but instead it dims to the point that i can no longer see the letters on the keyboard. I have viewed a youtube video about the normal adustment function, and mine is doing the opposite

My left shift key on Macbook Pro Retina (15") is behaving like the F11 key (show/hide open windows). The key behaves the same for the laptop keyboard and for an external Apple keyboard? This just started in last week after 6 months of use

My left shift key on Macbook Pro Retina (15") is behaving like the F11 key (show/hide open windows).
The left shift key behaves the same on the laptop keyboard and on an external Apple keyboard.
This just started in last week after 6 months of use. The right shift key and other keys on the keyboard all appear to work correctly.
Suggestions greatly appreciated.

I have a solution to this issue now after a discussion with Apple Support. Some where in the last few weeks, there was a change in the key that would do a Show Desktop under the Mission Control settings in the System Preferences. Even though the key sequence that was shown for the Show Desktop setting did not include the Left SHift key, by changing this first to having no key sequence and applying that and then changing it back to the F11 key, the Left SHift key issue that I was having has cleared up.
A second issue that was uncovered was that the SSD had some issues (uncovered when I ran Disk Utility using the Repair Disk key). I had to restart and use the Disk Utility through the Command R sequence to get to the stand alone Disk Utility. The SSD appears to be running better as a result as well.
Hope that this is of use to someone else in the future.

Shift key on the macbook pro 15 inch retina is unresponsive

I bought the macbook pro 15 inch retina just over a week ago and i'm definitely regretting it because the shift key is really unresponsive; what does this mean? I also want to know how to extend the track time on garage band. Anyone know how to? It's really bugging me because I need to type effencianly for a £2000 pound laptop it should be perfect to be honest.
I have the 2.5 ghz, 16 gb of ram and 512 gb flash storage.
The battery only runs out just browsing the web and it heats up very fast by only watching youtube...

My iMac will not boot up - held shift key - spinning gear does not advance - will not advance to home page??

My Mac will not boot up- advance to desk top- spinning gear keeps on going - white screen with apple logo only???
Held shift key - right after pushing power button

That is typically indicative of either a hard drive corruption or a hardware failure. What happens if you just let the Mac sit forever? Does it boot to a folder icon?
How old is your iMac? You may be able to run Hardware Diagnostics by booting up holding down the "D" key as well.

HT1338 My MacBook Pro (running Leopard 10.5.8) won't allow keyboard to type an upper case 'C' using the shift key...works fine with caps lock, or, with my Typinator workaround using double-typed lower case c (not always best). Any ideas?

My MacBook Pro keyboard won't type an upper case 'C' using the shift key... only with caps lock. Workaround has been to use Typinator by typing a double lower case c, not always the best solution. Mac is a refurbished model, which initially was fine. Apple tech helped me correct the quirk when it first appeared, but now it has returned and refuses fixes. Any ideas?

I'm willing to bet that this has something to do with iCloud. I've been facing a frozen computer nearly every time I go into it.
In Activity Monitor I have seen two programs associate with iCloud that take up about 2.5 GB of memory (I only have 4 in the computer) -- causing everything to freeze. One of these is called "iCloud Helper" and the other one is something like "Address Book Sync helper" -- I see parts of these names in the stuff you have posted.
I am at my wits' end with these and have written to Apple asking them to do away with these or fix them. To get rid of the Address book sync thing I have gone into system preferences for iCloud and unchecked Contacts -- but then spontaneously it gets rechecked. And oftentimes after I Force Quit the iCloud helper, it spontaneously turns on again. My conclusion --- the iCloud is basically unusable. It turns a Mac into the most useless, clogged, sluggish PC. If this is happening to a lot of people's computers -- and I see no reason why yours or mine should be an exception -- these programs just might destroy Apple itself.
So -- I'm about to completely give up on iCloud, and I suspect that others will too unless this gets fixed.
Cheers,
Bob

MacBook stuck with shift key enabled and numbers not working - even the keyboard app in languages wont type lowercase nor numbers?! Anyone know whats up? no spillage...cant understand why the keyboard app wont do anything.

Anyone have a clue? I can understand the keyboard being broke / shift key being stuck but why in the world would I not be able to type the numbers on the language keyboard app on the operating system? Numbers show up on the app but when I press them I still get the special characters like #^&#* and it wont type lower case. Nothing has ever been spilt, just stopped working one day. Rebooted from Time Capsule restore dated a month ago and its still doing it. (problem started two weeks ago). Only way to get lower case or numbers to actually show up is the copy and paste.
Any help would be amazing!
Details on computer: 13 inch MacBook6, 1 (Late 2009) / Intel Core 2 DUO / 2.26GHZ / 2GB / Memory running Mac OS X Lion 10.7.5

If you can afford it, I would recommend replacing the topcase and keyboard as Apple suggests. If like me, you can't afford it or are open to a hack fix, then read on.
The problem
Yesterday, a little water spilt on my 13" MBP keyboard. I turned it around immediately, drained out the water and used tissue to suck it all up but the keyboard was still acting funny. I turned it off and left it out in the sun for a couple of hours and turned it on again but problems remained. Like Rickdubya, my warranty had run out just a month ago and I knew Apple would not cover this under warranty. I tried to clean the shift keys and left it overnight with some rice on them with hopes that the moisture might get sucked out. Nothing worked. (The rice bit is an urban legend that seems to work with some electronics). Went to the Apple Store this morning and was told that they wouldn't even take out the key and clean it, and that the entire top case would have to be replaced. A total bill of 156 Euros which I cannot afford. I had a USB keyboard that would let me use the Mac for the moment so I decided to try to work out a fix.
Symptoms
- Boots in safe mode everytime (which I later found out was because the shift key is pressed)
- Cannot login because password is in lower case or has numbers
- Cannot boot in super user mode and try to disable keys or override password as some commands won't work in uppercase (I wouldn't recommend this anyway because its super user mode)
- All text is in caps and numbers are symbols as though shift key is always pressed
- Audio doesn't work
- Keyboard viewer would not always show the shift key pressed. The key seemed to get pressed at random
Fix
1. Hold the Option button down on boot to bypass the Safe Mode ensure a normal boot
2. At the login screen, plug in a USB keyboard and enter your password to login
3. Change your password to one that uses all caps and no numbers
4. Download and install KeyRemap4MacBook .
5. Use a combination of the functionalities of the Keyboard Viewer and KeyRemap4MacBook to figure out which shift key is the problem. In my case, I found out that it was only my left shift key.
6. Disable the left/right shift key on KeyRemap4MacBook and click on the 'Reload XML' button to make that take effect.
If only one shift key was the problem, then you are done. If both shift keys were shorted, then its likely other keys are too. In which case you should probably just replace the entire thing. If you think other keys are not affected, then you can use KeyRemap4MacBook itself to remap the shift functionality to a lesser used key like the Left Option key.
7. Under System Preferences > Users & Groups > Login Items , add KeyRemap4MacBook as an application that should start on login. This will ensure that your disable/remap of the shift key is active everytime you login.
Usage change/Things to remember
1. Remember to hold down the Option key everytime the computer boots or reboots to bypass safe mode. The fix above is at the software level. The key is physically still shorted at the hardware level and will affect boot.
2. Remember that at the login screen, the disable/remap is not active. So your password now has to be all caps and only letters.
As soon as I can save some money, I will get my topcase and keyboard replaced but until then this solution works great with minimal change. Hope this helps!

MacBook (not unibody) will not boot from Boot Camp USB Key

Hello
I have a MacBook Pro 2007 (17", 2.4GHz, 4GB RAM and SSD) with a defect SuperDrive, and I want to install Windows using an USB key instead. But the computer will not boot from the USB Key, even though the USB key works on my MacBook Retina. Also I was able to install Mountain Lion using USB Key, on the MBP 2007.
Here is a bit more details:
I've installed Mountaion Lion from the same USB Key (so boot from USB works).
I've installed a Windows 7 Boot Camp using the SuperDrive before (when it was not defected)
I've partitioned the harddisk using the Boot Camp assistant (this requires a Windows DVD in the SuperDriver... however it worked just enught to be able to have OS X recognize the Windows DVD, and create the Boot Camp partition). So far so good. Installing from the SuperDriver howerver does not work.
I've created an Windows USB Key using my MacBook retina. Because the Retina does not have a DVD, the Boot Camp assistant offers the creation of a bootable Windows USB Key from an Windows ISO file. I've used this USB key to install Windows on my MacBook retina.
When I try to boot my MacBook 2007 with this Boot Camp USB Key, it shows an "EFI Boot" option (with a orange USB logo) in the MacBook boot menu. When I select this nothing happpens. The mouse freezes, and the computer never boots.
Questions:
Shouldn't I be able to boot from an EFI USB Key on this MacBook 2007, when I'm able to install Mountain Lion using a USB Key?
When I installed BootCamp using the SuperDrive, I had to do som "magic" to make it bootable. Like this: http://www.logicalvue.com/2009/10/installing-window-7-x64-on-a-macbook-pro-using -bootcamp. I tried doing the "oscdimg -n -m -bc:\efi-dvd\boot\etfsboot.com c:\efi-dvd c:\efi-iso\win7x64.iso" trick and create a EFI bootable ISO and created the from this USB key using http://unetbootin.sourceforge.net/. Same result... the USB key shows up in the boot menu, but nothing happens when I select it (except the mouse freezes).
Any suggestions? Right now it feels like I have a bricked computer, because my kids needs Windows to run their games.
: Thomas

Thanks... I just tried rEFIt... and it almost worked.
After installing rEFIt I got several different boot options:
Bootmgr.EFI - This failed quick with a "unsupported" message
Bootx64.EFI - This actually started the Windows installation with "Loading files.............". But after a few minutes when all files was loaded, the screen went black. I tried ataching an external screen, but the screen was still black.
Boot from "Bootcamp" drive... as this drive is empty nothing happend.
Boot from "USB Key"... I'm not sure how this is different from the first 2 options... but nothing happend. I belive this is what happens if I try selecting the USB key from the build in boot manager.
Ofcause, whan I saw the "Loading files......" I thought I solved the problem, but as you can tell, I'm still stucked.
Actually... I tried with both Windows 7 64 bit, Windows 8 64 bit and Windows 8 32 bit. Only Windows 8 64 bit, got me to the "Loading files.....". This was created with the Retina Boot Camp assistant.
I also tried my own home made Windows 7 and Windows 8 ISO (created with this link: http://www.logicalvue.com/2009/10/installing-window-7-x64-on-a-macbook-pro-using -bootcamp).
I guess my problem is another now. I'll continue my hunt... but I don't have more time right now. So I've installed Parallels and Windows 8 for my kids. Not optimal, but at least the can play their games.
