  • HT1338 How do I update osx 10.4.8 if the network admin utility is not compatible with my apple airport extreme and I an't connect to the internet?

    I was given an iMac desktop computer, operating system OSX 10.4.8 (2011). The network admin utility is not compatiable with my airport extreme router, and I am unable to connect to the internet to update the software.   Can someone please tell me how to update the software or download a newer version on the network admin, or how to connect this computer to the internet?
    Thanks,

    I assume you have a PPC.  There is another update for the Intel.

    The first thing you should do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. How you do that depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
    1. You don't own another Mac.
    If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc, which you can get from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. I suggest you install as much memory as it can take, according to the technical specifications.
    If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. If you don't have the media, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
    To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
    If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
    2. You do own another Mac.
    If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to create a bootable USB device and boot the new Mac from it by holding down the C key at the startup chime. You will need the Apple ID and password that you used to upgrade. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
    Once booted from the disc, the USB device, or Internet Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive, which is what you should do.
    After partitioning, quit Disk Utility and run the OS X Installer. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
    You should then run Software Update and install all available system updates from Apple. If you want to upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
    If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Apple customer service has sometimes issued redemption codes for these apps to second owners who asked.
    If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to  authorize it under your ID. In that case, contact iTunes Support.

  • IPod 4,1 will not update to iOS 7. I updated my iMac to 10.9.1 (maverick). Latest Numbers version on iMac is not compatible with Numbers on iPod. Ideas? Can I go back a version with Numbers?

    iPod 4,1 will not update to iOS 7. I updated my iMac to 10.9.1 (maverick). Latest Numbers version on iMac is not compatible with Numbers on iPod. Ideas? Can I go back a version with Numbers? I downloaded old version of Numbers 2.0.1 from DVD but with both versions the 2.0.1 will not open.  So both versions are present but only the new version functions. I tried to drag the new version to the trash but the old version still runs error message and will not open. I did not try to restart with the new version in the trash.

    Maybe. See:

  • How do you burn a video file not compatible with quicktime?

    Hello all,
    I am very new at this so I apologize if the solution is very simple - i just can't seem to work this iDVD thing...
    I've searched through the forums and can't seem to find exactly what I need, please point me in the right direction if a solution has already been posted elsewhere.
    Okay, so my problem is trying to burn movies to DVD. I don't actually have to use iDVD, but it's the only solution i've come up with. My problem is when I add a movie file (lets say, something that will ONLY OPEN with VLC), and press preview, no movie files show up... but when i put in a video file that will play with quicktime, the preview works fine.
    So i suspect the preview wont play because the file is not compatible with quicktime.
    have any of you tried this? All i want is to be able to play a downloaded movie on the dvd player downstairs
    regards,
    Peter

    iDvd is not a general burn utility. However, there's a very good chance (whatever that file is) that Toast will burn it to Dvd-R. And if not (which is unlikely) then do as suggested already and use Mpegstream Clip. It's 100% free! However Mpeg 2 playback component may run you a few bucks (if needed).
    Or the alternative is to invest hundreds of dollars in Apple software and use apps like FCP and DVDSP (or FCS) along with QT Pro. Nine times out of ten this combination tends to work well ... but it ain't cheap (not to mention a rather steep learning curve).

  • How do I get my old iphone to sync with my new Macbook Pro?

    I just bought a new Macbook Pro and was able to get all my files and such from my old computer, which was a Macbook about 4 years old. But the problem now is that when I plug in my iphone to the new computer it will not recognize the phone in my itunes. I authorized the computer for my itunes account and everything is updated I'm pretty sure... so how can I get my new computer to "accept" my iphone?

  • The HP Deskjet 3050A All-In-One J611 series printer I just bought is not compatible with my Mac Book Pro.  What do I need to do?

    I recently purchased an HP Deskjet 3050A All-In-One J611 series printer and it is not compatible with the version of the operating system on my mac book pro.  I am currently running on OS X 10.4.11 and the printer is compatible with v10.5 or higher.  What can I do to update the operating system on my Mac Book Pro? 

    10.5 will be harder to find & more expensive, I think I'd go for 10.6
    Leopard requirements/10.5.x...
        *  Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor
    minimum system requirements
        * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)
        * DVD drive for installation
        * 9GB of available disk space (I say 30GB at least)
    Apple no longer has it for sale.
    Snow Leopard/10.6.x Requirements...
    General requirements
       * Mac computer with an Intel processor
        * 1GB of memory (I say 2GB at least)
        * 5GB of available disk space (I say 30GB at least)
        * DVD drive for installation
        * Some features require a compatible Internet service provider; fees may apply.
        * Some features require Apple’s MobileMe service; fees and terms apply.
    Which apps work with Mac OS X 10.6?...

  • New macbook does not "see" my network, old macbook pro and iphones do...

    Yesterday I installed an upgrade to my airport extreme base station, now my macbook pro and the 2 iphones in the household see the wifi network but the other macbook does not. It does see the neighbors wifi networks and will see it when I connect via a cable to the base station by no wireless connection... help!

    I am having a similar problem. I have 19 iBooks in a classroom and, suddenly, none of them can see the AirPort Express network when they log on. Instead, the iBooks try to connect to a Windows-based school network. I have designated the AEBS network as the only preferred network but the iBooks NEVER try to connect to it first. However, if you click on the AirPort icon in the menu bar, the AEBS network is clearly visible and clicking on it immediately connects you to the AEBS network.
    When I originally set up the network in January, everything worked just fine. After the upgrade to AE Firmware 5.7 and various OS X 10.4.5 updates, everything has gone downhill. I had the dropped signal problem that so many have reported. I downgraded to AE Firmware 5.5.1 and followed J. Exby's procedure to upgrade the AEBS framework. That solved the dropped signal problem. But now my iBooks cannot find the AEBS network when they log in.
    I have set the AirPort Network Preferences to connect Automatically or to Preferred Networks with the same result. I have also set the option to "Keep looking for recent networks" and it never finds our AEBS network. Yet, the network can be accessed manually through the AirPort icon.
    BTW, I use one of the iBooks myself and it works perfectly and finds my preferred network in 2 other locations with non-AEBS networks. But it cannot see its own preferred network in school.
    This is really bugging my students--and me! Any suggestions? THANKS!
