Mac OS X cannot install on this computer read  install read me on the DVD ?

Bought a used MacBook with a intel Core 2 Duo 2.2 Ghz with 2 gig memory and it came running leopard 10.05.1 on it already want to do a clean install of Leopard. DVD takes me to the point where i chose my language then i get this error saying Mac OS X cannot install on this computer read the install read me on the DVD
Any suggestions ?

If this is a retail copy of Mac OS X (not bundled with your mac), that may be the cause of your problem, especially if it was pre-installed with 10.5.1.
As far as I know, but I may be wrong, there is no 10.5.1 retail DVD (only 10.5.0), this could mean your mac is newer than the retail OS X DVD (10.5.0), and you have no other choice that using your Leopard DVD bundled with your machine, because your machine may have some hardware bot handled by the retail 10.5 DVD.

  • Downloaded iTunes 11.1.3; cannot find "authorize" this computer

    I downloaded iTunes for Windows, v.:11.1.3
    Cannot find "authorize" this computer. Where is this feature?

    There's a couple of ways to get through to the authorisation controls in the 11.0.x versions.
    The control is still in the Store menu, but first (if you're using iTunes versions 11.0.x) you might need to bring up the menu bar to see the Store menu.
    If you're using 11.0.x, click on the wee boxy icon up in the top-left corner of your iTunes to see the "Show Menu Bar" control, as per the following screenshot:
    Then you'll find the control in the Store menu:
    Alternatively, if you don't want to bring up the menu bar, it's still possible to get into the authorise controls via nested menus accessible from the wee boxy icon. Here's a screenshot of where to find them:

    I cannot authorize my new computer in iTunes because I hit the 5 device limit. However, I cannot deauthorize the old one because it's gone. I also cannot use the deauthorize all computers button because I did last year when I was replacing computers. Is there any other way of deauthorizing computers that no longer exist?

    If you no longer have, or access to, the computer(s) you want to deauthorise,
    Log in to iTunes,  go to "view your account info" on the itunes store, deauthorise all five,
    (Please Note: this can only be done Once every 12 months)
    Then re-authorize your current Computer(s) one at a time..

  • I cannot install an application in the Applications folder without removing it first

    For some time now, I have noticed that I cannot install an application into the application folder without first removing it from the folder. If I try to install it by dragging the icon to the application folder, I get a warning that the application can't be moved because the folder "Applications" can't be modified. I click on authenticate and enter the root username and password. I am warned that the application already exists in the location. I am asked if I want to replace the item. The options presented are "Keep both files", "Stop", and "Replace". I choose "Replace". I am then prompted for an administrator's name and password. I enter "root" and the root password. I then get this lengthy error message:
    The operation can’t be completed because some items had to be skipped. For each item, choose File > Get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again.
    I checked the permissions and "locked" was already deselected. The permissions grant my regular user read and write permissions, "staff" read-only, and "everyone" read-only. If I add "admin" with read and write permissions, nothing changes, i.e. I get the same error. If I try to enter my user credentials, they are rejected. My user is not an admin user. Previously, when I enterered the root username and password, the operation would complete successfully.
    Now if I first remove the application from the Applications folder, then drag the application to the folder, I am prompted for an administrator's name and password. When I enter it, the application is copied successfully.
    I have tried fixing file and directory permissions from the disk utility, but that doesn't fix the problem.

    When you say, "locked" was already deselected, I take it that you mean the small icon at the bottom right of the Get Info window displayed an open lock picture.
    Have you tried locking it, then unlocking it again?  I expect you will be able to lock it by simply clicking on the open lock icon, but to unlock it again you will need to supply an Admin password.
    Odd that DU didn't fix it.  That would be my first thought also.  Suggest trying it again, if you haven't already done so.
    Speaking of DU, have you verified your HDD?
    My Applications folder permissions read -
    System          Read and Write
    admin           Read and Write
    everyone      Read only

  • Cannot install Mavks. Get the message that HD is used for Time Machine B/U. Not true. Also Time Machine is turned off.

    Cannot install Mavks. Get the message that HD is used for Time Machine B/U. Not true. Also Time Machine is turned off. Running OS 10.8.5.

    That message appears when there's a "Backups.backupdb" folder in the root level of the OS X volume. This folder is used by Time Machine to store backups, being this the reason why the OS X Mavericks installer detects the OS X partition as used by Time Machine.
    To delete it, open a Finder window, select the Go menu (on the menu bar) > Go to Folder, and type:
    Then, delete "Backups.backupdb" and empty the Trash. Finally, open the OS X Mavericks installer in /Applications and follow the steps. Make sure you have got a backup of your files before upgrading and check that your apps are compatible > http://www.roaringapps.com

  • Cannot Install Item / Please restart the app and download your purchase again

    I haven’t had this error message myself but one of my colleagues has, any ideas?
    Cannot Install Item
    Please restart the app and download your purchase again
    Three of our team (including me) have now been able to download the entire app after first archiving and starting afresh but the forth guy (the Editor in Chief) is still struggling with only half available. He has deleted the Content Viewer app and downloaded it again without being able to download more than half the app (560 MB total).We are 10 days away from our deadline so at a critical stage.

    We just had a customer complain that they couldn't sign-in or upate.  We tried it on our devices and were able to sign-in successfully.  Then we tried archiving and re-downloading the folio they were trying to download.  It did the start-stop thing with the download numbers but eventually finished without me doing anything.  Then when it got to the install part of the process it only progressed to a tiny sliver and then didn't progress any further for at least 15 minutes.  I then canceled, re-downloaded again and the install process got to about 40% before hanging indefinitely.  I quit the Adobe Content Viewer app, restarted it and tapped on "resume".  It took a couple of minutes but it did finish the install.  When viewing the folio, about 40% of the way into the articles one of them was completely gray.  Essentially it wasn't downloaded/installed correctly.  I'm wondering if this might have something to do with the screen going to sleep so I changed the timeout from 10 minutes to 30 minutes.  The download and installation were successful, so I have archived and am re-downloading again just to hopefully repeat the success.  The folio is 306MB, so it's not huge but not small either.  Lots of videos and multi-state objects are in this folio but it has been downloaded and viewed successfully many times before.  No changes have been made to this folio for at least a couple of weeks.
    I'm very disappointed that we aren't past the point of these things still happening.  It makes it very difficult for us to pitch tablet apps to new customers when simple things like delivery to the end user is so unpredictable and frustrating for both our customers and us.  I hope Adobe realizes that lack of reliability is going to stop many users like our company from being able to recommend their system to potential digital publishing customers.  There are lots of companies/potential customers that want tablet apps, however why should we try to court their business if the platform isn't reliable?  We end up looking like incompetent fools because the system we told them to invest in isn't able to perform basic functions reliably.  If Adobe wants to make money from us and our customers we need the standard/basic features of Adobe's digital publishing system to work every hour of every day.  Rare exceptions and problems will always happen with any technology (even utilities like electricity and city water aren't bulletproof), however the problems users are experiencing haven't been rare.  We were an early adopter starting with the pre-release program in the hopes that we could offer customers a great solution and be part of the beginning of another great Adobe solution.  Up to this point we've tried to be very understanding of early growing pains with the technology and have apologized to our customers for the lack of a fully functional system many times and so far they have been patient and understanding.  The patience and understanding from both us and our customers is beginning to wear very thin.

  • A connection to the QuickTime server could not be established. This computer may be having trouble accessing the Internet or the server may be offline

    When I select “Update existing software in QuickTime Pro I get an error message saying “A connection to the QuickTime server could not be established. This computer may be having trouble accessing the Internet or the server may be offline”
    This has persisted for several weeks. Any help will be welcomed as I do not know how to contact QuickTime support via Apple.
    I am using Windows 7 64 bit.  
    Many thanks

    I was able to download and install the latest version of iTunes  (10.6.3.25) without a hitch. After the reboot I tried again to update my exisitng Quicktime Pro software as described in my original posting and got exactly the same error message.
    If it happens that there is no software to download because I am already running the latest version, surely a message to that effect would appear and not the one saying “A connection to the QuickTime server could not be established. This computer may be having trouble accessing the Internet or the server may be offline”
    Still seeking advice if possible
    Cheers

  • I just downloaded an album but one song won't play instead a message that "This computer is not authorized" to play the song. The prompt has a log in and when I log in it tells me the computer is already authorized. What gives?

    I just downloaded an album but one song won't play instead a message that "This computer is not authorized" to play the song. The prompt has a log in and when I log in it tells me the computer is already authorized. What gives? Specifically the album is Flying Lotus - Until the Quiet Comes and the song is DMT Song (feat. Thundercat). I purchased the entire album and it even played fine the first listen through.
