What can happen to an intel-based iMac when a power outage occurs while it is on and I unplug it to avoid a surge when power comes back?

The power went out today, while I was using my intel-based iMac (2008) and I rushed to unplug the power from the wall, before the poser could surge back on. Did I do damage?
I have a surge protector that it was plugged into, but I thought just to be safe I should unplug!
Thanks, Group!

Good point!
Art a surge protector (a good one) is designed to provide contant power to the devices that are plugged into it. This is good in the event of a surge of power up or down however in the event of a complete power outage they're of no value.
A UPS (Uninteruptable Power Supply) is just that, it has surge protection like a surge suppresor however it also has a battery integrated into it. The battery is designed to provide enough power for a user to do an orderly shutdown. In addition most UPS's can also plug into your iMac via a USB cable. Then you can set energy saver preferences that you cannot see now. For example you can set how long the computer should run in the event of power going off. You can also set if you want the computer to reboot or not when the power comes back on etc. For about $100 you can get a fine UPS that will add an additional layer of protection for your computer and give you extra peace of mind.

  • How can I format my intell based imac without the original Tiger discs? I have a user account on it that I dont want. I have upgraded to Snow Leopard but I want to to star affresh. Thank you.

    How can I format my intell based imac without the original Tiger discs? I have a user account on it that I dont want. I have upgraded to Snow Leopard but I want to to start affresh. Thank you. I have tried loading the Snow Leopard disc whilst holding down th C key but it goes straight into install mode. I am new to Macs and I have inherited this machine.

    Hello, many options...
    1. Insert the Mac OS X Install disc, 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 Erase 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. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, select the Security Options button, choose Zero Out Data, Erase... after completion do a new install.
    Or...
    Open System Preferences>Accounts, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
    In the same pref pane highlight your old account, click the little minus icon, then use Disk Utility to Secure Erase Free Space.

  • Intel Based IMac OS X 10.5.8 freeze on shut down and hang ups

    Have an Intel IMac8,1 OS X 10.5.8
    Computer has been freezing up on shut down, will log out and hold right at the shut down screen with a loading icon running.  Will have to force shut down with power button.  Applications have been loading slower than usual and computer hangs up frequently.  IMac has been offline(no internet connection) for about 6-7 months, reconnected recently. 
    Have updated all recommended updates, would my outdated operating system be the problem?  Not sure if during the time of being offline, important updates/firmware I might need?  Should I update my OS X or is their a fix/update that will work?
    Read a post about verifying permissions...?
    Any help would be greatly appreciated!

    would my outdated operating system be the problem?
    Nope, something else.
    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, 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 at top of the screen. (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. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a 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 completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
    Then see how many of these you can answer...
    See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
    http://support.apple.com/kb/PH7029
    Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
    How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
    Open Console in Utilities & see if there are any clues or repeating messages when this happens.
    In the Memory tab, are there a lot of Pageouts?

  • Can I clone an intel based iMac to a powerbook G4

    I have an intel iMac (2006) running Tiger, and have just procured a powerbook G4. Is there a way to clone the iMac onto the powerbook. I do;t have much knowledge of the differences between the intel chips and powerpc chips as to whether they cause issues being synced with each other. What I am looking for, is to be able to use the laptop for travel and have the iMac at home, but the flexibility of the data synced - like email, calendars, contacts...etc.
    Any help will be greatly appreciated.

    It depends on precisely what you mean by "clone". If you just want to synchronize data, there are utilities such as ChronoSync that can keep your systems in sync. As long as you use the same apps, it shouldn't be a huge problem though it can be a bit tricky with some apps to figure out what needs to be synced. It's generally not recommended to try and clone the OS and applications themselves between Intel and PowerPC Macs, even if you have legal licenses to run the OS and apps on two systems, since you often don't get the correct versions onto the second system.
    Hope this helps.

  • My old Intel-Based iMac is no longer recognizing USB wired input devices; it only recognizes Bluetooth.  What happened?

    My friend's old Intel-Based iMac is no longer recognizing USB-wired input devices (Kensington TrackBall, Logitech Mouse) plugged into any USB slot at the back of the computer.
    They were working before and for many years.
    All of a sudden, A pop up window came up. IT said no Bluetooth mice could be found.  We don't know what set off that window to pop up and look for a WL mouse. It never has before in the 5 or more years my friend has been using this computer.
    I supplied a wireless Apple mouse and his is back running again.
    But want to know why his USB-input devices (Except his keyboard) are not being recognized. He would prefer to use his  Trackpad (Wired), but can't find anything in SYstem PReferences to allow that.  The computer only seems to want a Bluetooth input device.
    Anyone have an idea what happened and if this can be reversed?
    I think he is still running Mac OS X 10.5.8.

    Hi Carol, lets try this...
    reset FW bus, same goes for USB reset...
    Reset the Firewire bus
    If your Firewire or USB isn't recognizing any device.  A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
    1. Shut the machine down.
    2. UNPLUG the power lead to the computer and any firewire/USB drive/devices.
    3. leave it for 10 minutes.
    4. Connect back up and reboot.

    On your friend's computer with an internet connection, log into the Mac App Store with your ID and download Yosemite from the Purchases section of the Mac App Store. The make a bootable USB install media using
    http://liondiskmaker.com/
    Then boot from that on your computer and install
    You need an internet connection to install via Recovery mode

  • Intel-based iMac stuck in grey screen with spinning wheel. SMC::smcReadKeyAction ERROR THOP kSMBadArgumentError(0x89)

    Hi guys,
    since yesterday my Intel-Based iMac doesn't boot normally, its stuck in grey screen with a spinning wheel.
    Its an Intel-based iMac 21.5'' purchased in 2011, and i recently (2 months ago) upgraded it to Mavericks.
    -2 weeks ago, i installed smcFanControl app
    -Tried start up in Safe Mode by holding Shift but its not working. i think i hear fans are working more than they were before the problem occurs.
    -entered Single User Mode and i get an error
    SMC ::smcReadKeyAction ERROR THOP kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff8029fa1000
    -followed some instructions found online, but can execute the correct commands in SingleUserMode
    tried to remove FanControl as explained here: http://apple.stackexchange.com/questions/110667/errorr-kernel-smcsmcreadkeyactio n-in-console
    any ideas what may caused this and how can i fix this?
    Thanks in advance

    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 startup failure is to secure the 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 the last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
    b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, boot from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
    c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    d. 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
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up 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.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up 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, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup 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 restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the 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 restart as usual.
    Step 9
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 10
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 11
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 12
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • Upgrading FCP 4.5 HD from Power PC to Intel based iMAC

  • Using a PPC backup for an intel based iMac

    I used my external hard drive with my PowerBook TM backup to migrate my data to my new intel based iMac. Afterwards I formated the external hard drive to the GUID scheme and initialed a TM backup. But somehow in the midway TM stopped backing up and produced this error message:
    +Starting standard backup+
    +Backing up to: /Volumes/Backup/Backups.backupdb+
    +Event store UUIDs don't match for volume: Macintosh HD+
    +Event store UUIDs don't match for volume: Medien+
    +No pre-backup thinning needed: 71.14 GB requested (including padding), 285.93 GB available+
    Is it not possible to use a PPC based TM backup to restore it on an intel based machine?

    Well, that's not what the error means. There's a problem with the UUIDs of the volumes involved. However, that said, no you cannot put a PPC version of OS X on an Intel Mac. However, you can restore your data from any TM backup. But if you did a full system restore from your PPC system backup to the new machine, then you have a problem for which the only solution is to erase the internal drive and reinstall OS X using the original discs that came with the new computer.
    I'm not really sure what you are trying to do, but if you actually formatted the external drive and re-partitioned it using GUID and are now trying to initiate a TM backup of your new Intel Mac, then I recommend you simply reformat the external backup drive Mac OS Extended, Journaled (and check to be sure the drive is partitioned as GUID,) and then reconfigure TM preferences and start a new backup.

  • Intel based iMac start up problem

    Sometimes when I turn on my intel based iMac instead of seeing the apple symbol it shows a symbol of a flashing folder with a question mark in it.
    I turn it off and wait a few minutes and turn it back on and it starts up correctly.
    Anyone else have this problem? What does it mean?
    Thanks

    It means that the computer can't find a valid drive to boot from. Try starting from your Leopard DVD and repairing your disk and permissions.

  • AppleWorks Software & Intel based iMacs

    Will the new Intel based iMacs have Appleworks installed as part of the included software bundle?
    iMac   Mac OS X (10.2.x)  

    I expected AppleWorks to not be able
    to run under Rosetta as it is a carbonized OS 8/9
    application, not a native, cocoa, OS X app.
    I've heard a few of people say this, but it's a misunderstanding. Both Carbon and Cocoa applications will run under Rosetta.
    For example, Steve demo'd MS Office and Photoshop running under Rosetta at last year's WWDC and this year's Macworld Expo. Both applications are written with the Carbon API.
    I'd expect that AppleWorks 6 will run in Rosetta, although it's possible it might not. Here's what Apple's guidelines about Rosetta say, and why I'm positive about AppleWorks under Rosetta/Intel Macs:
    "Rosetta is a translation process that runs a PowerPC binary on an Intel-based Macintosh... . Many, but not all, applications can run translated... How compatible your application is with Rosetta depends on the type of application it is. An application such as a word processor that has a lot of user interaction and low computational needs is quite compatible...
    Rosetta does not run the following:
    Applications built for any version of the Mac OS earlier than Mac OS X —that means Mac OS 9, Mac OS 8, Mac OS 7, and so forth
    The Classic environment
    Screensavers written for the PowerPC architecture
    Code that inserts preferences in the System Preferences pane
    Applications that require a G5 processor
    Applications that depend on one or more PowerPC-only kernel extensions
    Kernel extensions
    Java applications with JNI libraries
    Java applets in applications that Rosetta can translate; that means a web browser that Rosetta can run translated will not be able to load Java applets.
    <http://developer.apple.com/documentation/MacOSX/Conceptual/universalbinary/universal_binary_exec_a/chapter_7_section_2.html#//appleref/doc/uid/TP40002217-CH210-BCICICJH>
    AppleWorks is not described by any of the items on the list above, so chances are good it'll work with Rosetta. And given the speed of the Intel Macs it should perform well.
    Cheers.
