After updating software - can't boot

I updated software last night but didn't take the time to upgrade the firmware ( instead I shut it down) and now it will not start up past the blue screen.

Do you mean that you turned it off during a firmware update?
If so, you will need to try to repair the old Firmware before you can get things working again.
You can read more about this at:
http://docs.info.apple.com/article.html?artnum=303469
And, you can download the restoration CD at:
http://www.apple.com/support/downloads/firmwarerestorationcdv10.html
You will need to download and create the CD on a different Macintosh that is still operational.
Hope this helps you out. Let me know how it works out for you.

  • HELP... after 10.4.11 update I can't boot past the blue screen

    HELP... after 10.4.11 update I can't boot past the blue screen, and it is pretty frustrating, to say the least. Here's what happened last night:
    I installed elgato's eyetv 250, and at the end it asked to update the software. I did so, and when I tried to run it again it said I had to be running 10.4.11. I quickly went over and downloaded the 10.4.11 combo updater to my desktop and proceeded to repair permissions on my disk so I could run the updater.
    I repaired permissions and started the updater. It got halfway through updating and said something like it could not finish and stopped. No reason why - it just stopped. I tried it again, and it did the same thing after going about 25 to 30 percent through the updating process. I thought that was very odd, so I checked, and I was running 10.4.9.
    I thought I needed to get the 10.4.10 update, so I downloaded the combo updater several times. It would not run, giving me some error message that it would not even open, so I thought I needed to restart my computer to get it to run. I did so.
    That's when my computer would not boot. It gets through the initial white screen with the logo in the middle and the revolving circle, and while it stays there for a long time the fans run increasingly faster. They tame down, and then the blue screen with "Mac OS" on it and the blue progress bar comes up. There is no blue progress bar, though... that's where it stops and will not go any further.
    Can ANYBODY help me get this thing booted back up? It was so late last night that before I started I didn't back the Mac up, and of course I have a project on there that I need to finish Saturday afternoon for a company.
    ANY HELP WILL BE SO GLADLY APPRECIATED. If you can give me step by step instructions on what to do, you will surely be blessed! Thanks for any help,

    Hi mrstang, and a warm welcome to the forums!
    It sounds like Disk Directory problems.
    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then Safe Boot , (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
    The usual reason why updates fail or mess things up, or things don't load/run, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
    Some people get away without Repairing Permissions for years, some for only days.
    If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
    If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates again, or even do an A&I if you have enough free disk space.
    The combo update for PowerPC-based Macs...
    http://www.apple.com/support/downloads/macosx10411comboupdateppc.html
    The combo update for Intel-based Macs...
    http://www.apple.com/support/downloads/macosx10411comboupdateintel.html
    Repair Permissions before & after re-install, then reboot again each time.
    If all the above do not resolve the problem, then it's time for an Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space...

    Be sure to use Preserve Users & Settings.

    After updated software on mac mini with os x 10.7.5 and restart the mouse pointer after about 30 sec. converted to the rainbow wheel and I can't control the computer. The rainbow wheel was runnig 8 hrs and I turn off mac mini by power button, then I turn on mac mini with key Shift and p/w, checked HD. My HD has

    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 safe mode.
    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 copy 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 (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below to select it:
    for k in /Sy*/L*/Ex*/{,.?}*.kext; do test -f "$k/Contents/Info.plist" && /usr/libexec/PlistBuddy -c "Print :CFBundleIdentifier" "$_" | egrep -qv "apple|Accusys|ArcMSR|ATTO|CalDigit|HighPoint|hp-fax|JMicron|print|SoftRAID|stex" && echo $k; done | open -f -a TextEdit
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    sudo defaults read com.apple.loginwindow LoginHook | open -f -a TextEdit 
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    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 
    Repeat with this line:
    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 | open -f -a TextEdit
    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. 
    Step 4
    osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null | open -f -a TextEdit 
    Remember, Steps 1-4 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • After updating software on my Apple TV it is asking to connect to iTunes. Can't understand why?

    After updating software on my Apple TV it is asking to connect to iTunes. Can't understand why?

    You can try borrowing one. These cables are common for Android, Kindle etc. users.
    Here are some steps and notes to try:
    MANY people are reporting they've had to try multiple micro USB cables to find one that works. I got one that worked from a neighbor.
    For clarification, this needs to be a "micro" USB, not a "mini" USB
    Some people have also reported they've had to try the Restore process more than once.
    1. Unplug Apple TV and move it to your computer running latest version of iTunes.
    2. Quit iTunes if running.
    3. Plug micro USB cable to the back of the Apple TV.
    4. Power the Apple TV using  the AC cable.
    5. iTunes shoud either launch itself (a good indication that the micro USB cable you're using is compatible), or launch iTunes.
    6. Click Restore. Software will download and install (big file).

  • After updating software, apple tv no longer accesses mob.tv and wsj

    After updating software, my apple tv no longer accesses MLB.TV and the WSJ.  It shows a spinning icon, sas accesing mlb., but never finishes.
    This happened once before with an upgrade and the solution was to update using a USB wire.  I took the apple tv to the store, and they did this (or they said they did), but the wired connection to MLB NO LONGER WORKS.  It will work as a wi fi, but will not work with wire.  Help!  How can I get mlb back p and running for the 5 days of the year I want it most.

    Is your Apple TV correctly connected to the network (check you don't have an IP address that staqrts with 169)
    Have you checked homesharing is still set up properly, what about your computer firewall, is set to allow access for iTunes, you might try turning it off too.

  • I could not activate the phone after updating software to iOS7.

    Dear Apple Support team.
    Please help to investigate the problem as I could not activate the phone after updating software to iOS7. in the phone the erroe message is "Your iPhone could not be activated because the actiovation server cannot reached. Try connecting your iPhone to iTunes to activate it, or try again in a couple of minutes.
    I have try to activate both of way such by WiFi & Cellular activation and connecting with iTunes but still face the problem and could not completed activation the phone.
    How do i activate the phone or have to wait for hour not couple min as you suggested.
    your feedback quickly would be appreciated.
    Thank You

    There is nothing you can do. That is the Activation Lock that Apple has implemented tout down on theft of their iPhones.
    Most likely the iPhone is stolen.
    It is totally worthless to you.

  • Repairing permissions before and after updating software

    What is the reason to repair permissions before and after updating software? This may sound like a stupid question to many of you, but I am new to computers and I am trying to learn how and why of some of the things of my PowerBook. I installed some updates without repairing permissions. Did I install some software updates the wrong way? Thank you.

    This is a topic which will draw as many emphatic for and against responses as overnight shut down or not, defrag or not, optimise or not, and so on.
    I agree with Neil. I believe that OS X has progressed sufficiently that repair permissions has become redundant and so I do not do it on any regular basis.
    Some folk may refer you to an Apple Support Article 303602. That Article in its 4 May 2006 version, titled "Top 10 Tips to Keep Your Mac in Top Form" suggested Repair Permissions should be done "after upgrading or installing new software". The Article was however revised on 15 May 2006 to be titled "Top Tips to Keep Your Mac in Top Form" and the item on Repair Permissions [along with two other recommended maintenance tips] was removed. It is my view that the conclusion to be drawn here is that Apple no longer considers Repair Permissions to be a required maintenance procedure.
    Many users have adopted a "Repair Permissions" mantra for a cure-all over several years. I dropped it sometime in 10.3.
    But, to each his own.

  • TS3276 After updating software yesterday, noticed that sent emails are not showing up in Sent Folder for one of my accounts.

    After updating software yesterday, noticed that sent emails are not showing up in Sent Folder?

    Are you storing Drafts, Sent, Trash and Junk messages on the server via your .Mac account with Mail?
    If so, do you access your .Mac account with an email client on another computer or regularly access your account via webmail on another computer?
    If not, any other reason you need to store Drafts and Sent messages on the server?
    While composing a message with Mail, it is temporarily saved in the account's Drafts mailbox so sounds like something went wrong with the process between finishing and sending the message with Drafts and Sent being stored on the server.
    If you don't have any need for this, better to store Drafts and Sent messages locally on the hard drive with Mail.

  • Slow after updated software

    After updating software, Maverick 10.9.4, on my Mac, it is very slow especially opening apps. Any recommendations?

    Launch the Console application in any of the following ways:

    ☞ 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 Console in the icon grid.
    The title of the Console window should be All Messages. If it isn't, select

    from the log list on the left. If you don't see that list, select
              View ▹ Show Log List
    from the menu bar at the top of the screen.Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
    The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
