I tried updating my Macbook Pro and now it won't work?
I had OS Mountain Lion 10.8.2 for my MacBook Pro (version: late 2012) and I tried updating the operating system. The update was about three out of seven minutes in when a box popped up and said there was an error updating and that the process must restart. I clicked "okay" and waited for a couple of minutes but my screen was all gray and nothing else. I thought my MacBook froze, so I manually restarted it by holding down the power button and then pressing it again and now my screen is gray with the apple symbol and black coded text with writing such as "Unable to find driver for this platform", "Mac OS Version: Not yet set" and "System uptime in nanoseconds: 242856217", along with a series of codes such as " panic(cpu 0 caller 0xffffff8008c59241)". The screen is stuck like this and will not change. I have tried manually restarting it but it just keeps showing this screen. How can I fix this?
Thanks in advance!
Reboot your laptop while holding the alt/option key then I prefer you connect your laptop to an Ethernet cable because wifi gets slow . We'll, now choose the recovery driver. After that choose reinstall whatever software and just wait for a few hours for the thing to install and then your basically done hopefully no files will be earased since that is what I did and everything was perfectly fine no files lost, nothing
Good luck

I just updated my macbook pro and now every time i go to youtube it tells me I have to download the new version of adobe flash player so i do and it still wont let me play it ..
Assuming Allan's advice is not correct, and you do run the installer, I think I've heard of that problem and it involves removing the old Flash plug-ins, then install the new version. I don't use it so I don't know what they are called, but will be the /Library/Internet Plug-ins folder.
You can go here and enable HTML5 in YouTube so you don't have to use Flash: http://www.youtube.com/html5
Most(?) of the content is HTML5, but you may run into videos where you still need Flash. -
I just updated my Iphone 3G and now it won´t work anymore. It wouldn´t even boot. It was just working for 3 sek. after the installation and now it shut itself down. Any help, please? Thankyou
I suspect you have a 2G iPod. Those can only go to iOS 4.2.1.
Identifying iPod models
iPod touch (3rd generation)
iPod touch (3rd generation) features a 3.5-inch (diagonal) widescreen multi-touch display and 32 GB or 64 GB flash drive. You can browse the web with Safari and watch YouTube videos with Wi-Fi. You can also search, preview, and buy songs from the iTunes Wi-Fi Music Store on iPod touch.
The iPod touch (3rd generation) can be distinguished from iPod touch (2nd generation) by looking at the back of the device. In the text below the engraving, look for the model number. iPod touch (2nd generation) is model A1288, and iPod touch (3rd generation) is model A1318.
You also said: "It also will not let me download any music onto it." What happens when you try to sync music to the iPod? -
I wiped down the touch pad on my MacBook Pro and now it's not working well
I wiped down the touch pad with a damp cloth on my MacBook Pro and not it's not working very well. What should I do to fix the problem?
Let it dry, it will come around. You just chilled it a little most likely, unless the cloth was very damp....
Next time use rubbing alcohol.
It removes the oils and grease and dries fast too.
So your have appy to the cloth, wipe, flip the cloth and wipe up the dirt and grime, then start the process with a new clean section of cloth, else you place the grime back on. -
I just (10 minutes ago) downloaded an update to Firefox Sync and now it won't work
A few minutes ago (10 November 2010 18:00 GMT approx) I downloaded an update to Firefox Sync after getting a prompt and now it won't work. It is not listed under tools as before or in the browser taskbar. It appears as a green jigsaw-puzzle-piece in my list of add-ons saying "this add-on will be installed when you restart Firefox". I have restarted FF about 5 times now and it still won't install. I have the most up to date version of FF.
I assume Google toolbar extension is not compatible with Firefox 5.
You can try this extension to override compatibility issues,

I have recently updated my MacBook Pro and now it crashes once my Desk Top completely loads
Has anyone had a similar problem after loading the latest operating updates?
After switching on the MacBook Pro and entering my password, all goes well until my desktop and icons load. Once this happens it switches itself off.
SOlutions Inc have backed up everything for me, reloaded the older version and all is fine. Then once they try and upload the latest version the whole issue starts again!! This is starting to cost me money!
The Genius Bar at Brighton can't get me in until Sunday 19th April, can anyone help with this issue? I am a novice so any ideas need to be pretty straight forward.
Many thanks
Bonsai Bill1. 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.
The test works on OS X 10.7 ("Lion") and later. I don't recommend running it on older versions of OS X. It will do no harm, but it won't do much good either.
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. See, for example, this discussion.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a general summary of what you need to do, if you choose to proceed:
☞ Copy a particular line of text 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.
These are not specific instructions; just an overview. The details are in parts 7 and 8 of this comment. The sequence is: copy, paste, wait, paste again. You don't need to copy a second time.
5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
You may have started up in "safe" mode. 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. Load this linked web page (on the website "Pastebin.") The title of the page is "Diagnostic Test." Below the title is a text box headed by three small icons. The one on the right represents a clipboard. Click that icon to select the text, then copy it to the Clipboard on your computer by pressing the key combination command-C.
If the text doesn't highlight when you click the icon, select it by triple-clicking anywhere inside the box. Don't select the whole page, just the text in the box.
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 to activate it. Paste from the Clipboard into the window by pressing command-V, then press return. The text you pasted should vanish immediately.
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. If you don't know the password, or if you prefer not to enter it, 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, a series of lines will appear in the Terminal window like this:
[Process started]
Part 1 of 8 done at … sec
Part 8 of 8 done at … sec
The test results are on the Clipboard.
Please close this window.
[Process completed]
The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it and go to the next step. You'll have incomplete results, but still something.
12. When the test is complete, or if you stopped it because it was taking too long, 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 "The message contains invalid characters." 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 for themselves, not for me. The test itself is harmless, but whatever else you're told to do may not be. For others who choose to run it, I don't recommend that you post the test results on this website unless I asked you to.

How do I fix this issue???
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in 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.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. -
I updated my MacBook Pro and now when i login in it shuts down by it's self
This morning I did a Software update on my Mac Book Pro (Security Update 2015-003 1.0), I saw the progress bar for it's installation and shortly after my laptop restarted. I typed in my password and the progress bar appeared on my screen - it loaded to about 30% before it froze for 20 minutes; I shut it off and tried to restart. But this time the progress bar loaded to 50% and then it froze so once again I waited and then pressed the power button. I waited a few hours before turning it on again, i typed my password, the progress screen appeared for about a minute as it loaded to about 40% and then it shut off. I tried it twice and the same things happen. I do not have a backup and am worried of losing data.
PS: Just to add i tried to go in to "Safe Mode" by rebooting the laptop as many of the other posts have suggested, but to no luck it just didn't work.Try booting to recovery and repairing the HD

I have not used my MacBook Pro for a few months and when I started it up did all the microsoft and system updates. Now it will not turn on and it goes to a grey page that state "You need to restart you computer. Hold down the Power button untilmitmturns off, then press the Power button again." I have done this several times and keep arriving at the same page.
OK, then there is little else to do other than to reinstall OS X.
Make sure you removed everything connected to the MBP including any USB devices.
If your Mac came with a System Install DVD, then insert it and hold the c key while starting your Mac. This will boot from the DVD instead of your internal disk.
If you find the grey screen reappears then it may not have restarted from the disc, so try again. You have to get past this step to do anything. If you can't, the problem may be a dirty or damaged DVD or an inoperative optical drive.
When it gets to the Mac OS C Utilities screen, select Disk Utility and repair your hard disk. Record any errors that it finds, since your problem may be due to a failed hard disk. If that is the case, the failure will probably arise again.
Then, reinstall OS X. Reinstalling is non-destructive to your user accounts or data.
If your Mac is running Lion, or Mountain Lion, you can boot OS X Recovery and perform all the above without a disc.

Updated my macbook pro and now it wont turn on
Okay so I'm on my MacBook and there is an update. I update my laptop. It was at 100% and my computer needed to restart for it to update. Update takes 11 minutes, It shuts down. I try to turn it on. You can hear the opening sound but nothing happens on the screen
You do not specify which model Macbook Pro you have. If it is one where you cannot remove the battery, try this:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Dented my Macbook Pro and now it won't start up. Please Help!
Hello. I have searched and searched and cannot find a solution.
Last night I was putting the finishing touches on my dissertation and accidentally dropped a tape dispenser on my 1-year-old MacBook Pro - it hit just to the left of the trackpad and left a nice little dent! After the "incident", I was attempting to pull up Word and the machine completely froze. I turned Mr. Mac off by holding down the power button and when I tried to restart, I never got past the Apple logo with the little spinning circle. After trying many times to restart, I made it to my desktop only twice, and after the dock appeared (with no menu bar above or desktop icons), the machine froze again. Each time, I heard the hard drive working until the big freeze.
I was able to boot off of the Leopard install disc and ran "repair disk" on my hard drive - no errors were found. Tried restarting again and got nothing. I have since tried restarting with various key combinations and the machine only responded to "C" and "Option".
This morning, I searched again and decided to try the "optioncommand+pr" to reset the PRAM as suggested to another damsel in distress with a similar issue. Now, when I try to restart, I get the gray screen followed by the chime, and then nothing - no hard drive working, no Apple logo, no spinning circle, nothing. My install CD will not spin and I none of the start-up key combinations work. It just sits there staring at me with that gray screen - laughing because my dissertation is in there somewhere and I can't get it out! Yes, I have backed my maching up on a 500G external hard drive, so I haven't lost much - but I can't access my hard drive without Mr. Mac! And I am a lonely Mac owner here - no others to borrow!
I am going to an Apple Store on Saturday, but I thought I would give you guys a chance to save my life first. Any suggestions for this girl and her Mac would be great! I am defending my dissertation next week and I'm about one small crisis from a major meltdown!!!!!!
Thanks!Well, my two-month-old MBP has no qualms about booting from a no-name external USB HD I put together...
Given that is is a common point of failure, I would imagine a large Apple Store should keep a stock of HD's on hand.
Now since you're a bit desperate and the genie pops up til Saturday and you seem to be the enterprising kind, let's try an experiment: if you have room enough in the external HD and assuming it isn't a Time Machine volume, why don't you plug it in, stick the Install CD and see if the installer lets you select the external drive as the install target. If you can install Leopard on it, on top of the backup without reformatting, and the Mac can boot from the drive afterwards, at least you would have some functionality restored and would be able to pull your stuff from the internal HD. Apple says booting from USB drives is not supported but that does not equate to not possible; some brands do work. Risks? Always. You can always lose your backup. Like I said, a challenge for an enterprising gal....
Next time around, consider having a bootable external clone at hand for rainy days. I keep three myself...
P.S. Since I'll be in the Dallas-FW area in late June, I can volunteer with the confetti.... -
I have a macbook pro, bought new in Sept 2011.
Yesterday, I changed the date (forwarded it to 2020 - for a silly reason) and then changed it back. Now my iMessage on the macbook shows up that all contacts are offline and when I can't log in.
I've trawled through a number of the already-existing threads on this and tried a few things - in Terminal, or in Systems Prefs but can't get it to work.
Any thoughts?
Thanks, Pádraig.Log out or restart the computer and try again. Make sure the date is now correct.

I opened my Macbook pro and now it won't start
So I started to have issues with my MacBook Pro not recognizing the hard drive. I opened it up and started to see how dirty the inside was so I took the logic board and battery and cleaned them up.
