I cannot upgrade 10.6.8 to Mavericks.

"This copy of the Install OS X Mavericks application can't be verified." Date/Time settings are accurate. MacBook Late 2008 Aluminum: Model ID 5,1. I have also tried deleting/re-downloading install file.. Help?

I have also tried doing a clean install with a bootable USB. Install keeps failing. So re-loaded computer with Snow Leopard.

  • Why i cannot upgrade iPhoto and iMovie in mavericks version?

    How to fix it?

    Go to System Preferences and switch your language/region to English/United States and try again. This worked for many users in Europe. Looks like it might be a glitch. After you upgrade switch back to your original language and region.

  • Since I uploaded the new OS X Mavericks the App Store, Messages, Notes, Calendar, Maps and Preview will not launch/open. In Finder cannot find my files. Most crucially cannot upgrade OS X Mavericks software. I had two apple ID's, the old one not used

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Please take this step regardless of the results of Step 1.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    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.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • HT201364 Cannot upgrade to Maverick

    I have a MacAir purchased in Nov 2008. It has 2 GB RAM and OS X 10.6.8. However, when I click on OS X Maverick upgrade, it says cannot upgrade. Any idea why? Thanks.

    After you find the Model Identifier, go to this page:
    http://support.apple.com/specs/
    Copy the Serial number in the "Search Tech Specs" search box. This will take you to the info on your computer. You can also check to see how much RAM you can install.
    While 2GB RAM is the minimum recommended, I suggest you upgrade your RAM to 4GB or higher. Otherwise you might be better off in Snow Leopard.

  • Cannot Upgrade Apps in App Store?

    Hi all
    Plz help me, I'm using iPhone 5s AT&T (Unlocked). Today, my iPhone cannot upgrade my applications that I've downloaded previously. But still be able to download new applications.
    My iPhone:
    5s - 16GB - Gold
    Using Carrier: Viettel in Vietnam.
    iOS: 7.1
    Tks all.

    Thank you both! You both solved the problem by pointing to the keyboard preferences, but it seems I can only mark one answer as 'This solved my question'.
    When I checked System Preferences > Keyboard, under Text I found a list of automatic replacements that included my namebeing converted from English to Japanese. (I know they weren't there before Mavericks!) As a bonus I also found that I could choose British spelling, which seems to have solved another problem I had up until now of Word automatically slipping back into American spelling even though I'd set everything for British - I write/proofread for a living, so this was a big headache and Microsoft hadn't been able to explain why this happened.
    My only input source has always been Kotoeri. The 'flag' shows a large letter A when I'm typing English and a hiragana あ or a katakana ア when I'm typing Japanese. I had no problems until Mavericks (except with Word).
    I'm in Japan, so the Japanese flag at the bottom of the App Store page is the 'correct' flag. I tried changing it to the UK flag to see what would happen, and when I tried to sign in (successfully this time, no conversions) I got a message saying my ID was valid only for Japan, and got automatically switched back. The iPhoto update seems to be downloading no problem now.
    Again, thank you both very much.

  • HT201364 Cannot upgrade OS to Yosemite

    Hello, Im new to this website. Im having issues with my Macbook. I have the old 2009 model Macbook and it is our schools macbook. The school just upgraded these MacBooks to OSX Mavericks and when i try to open Minecraft it won't let me. It says no jdk installed. I also try to install Java SE runtime but half way through the Software Update it says cant download software because of network problem but I'm connected to the internet and i can browse stuff just fine. Can any one help with my problems. P.S. I don't know the administrator password or stuff like that. And yes we are allowed to play games and stuff on these laptops but only at home not at school so don't tell me i need to focus on school and not games. 

    Since you updated the operating system, it is probably Minecraft is missing certain files that ware remove or are not longer comparable with the new version of the OSX. what I recommend, is to check is there is an update for Minecraft and install that. If there is not update available, probably the best thing will be reinstalling Minecraft. Hope this will help you.   

  • I cannot upgrade from iOS 5.-01 to 5.1 on original iPad

    My wife and I both have iPads running 5.0.1. Mine is v2 and hers is v1. We both have Macs with 10.7.3 and iTunes 10.6.
    When I tried upgraded to 5.1 throguh iTunes I got messages saying I could not connect to the server. A friend suggested I reboot the iPad and my Mac. I did and the upgrade went fine.
    I cannot upgrade my wife's iPad, however. Even after rebooting I get an error saying iTunes cannot download the upgrade because her computer is not hooked up to the internet. It is, however. I can access the iTunes store, use Safari, and get e-mail. I then tried to download the upgrade directly through the iPad but after a few minutes I get a message saying the updte failed.
    Any suggestions?

    Problem solved. I upgraded after switching a cable. Not sure why that mattered but all is fine now.

  • I have upgraded from Mountain Lion to Mavericks, since then my Adobe Flash Player don't want to work?

    Hi, can anybody help me please, i have upgraded from Mountain Lion to Mavericks, since then my Adobe flash player don't want to work.
    I clicked on update and downloaded the update from Adobe and installed it.
    Every time i get an error saying - "that this wasn't downloaded from App Store".
    i can not find it in App Store.
    What must i do?

    Try this: in your Utilities folder launch Adobe Flash Player Install Manager and run it to completely uninstall Flash. Then go to http://get.adobe.com/flashplayer/ and download Flash
    Once downloaded, double-click to open it and run the installer. If you get a message saying the file can't be opened, or similar, Control+click or right click and select 'open' and should then be able to proceed to install it.

  • I upgraded to OS Yosemite on my MacBook Air...and I cannot upgrade the Adobe Flash download that Adobe keeps asking me to download. I get the screen and when I click on the icon it just creates a new window but not download. Thoughts?

    I just tried the link and it is just fine. If the GateKeeper pops up then open Security & Privacy preferences, click on the General tab, set the last radio button to Anywhere.

  • I'm using a 15" Macbook Pro running OSX6.8 and cannot upgrade. I have a subscription to Adobe CC but none of these work on this so I was on with Adobe for 5 hours trying to install and launch Illustrator, InDesign, Photoshop, Muse, and Acrobat Pro from CS

    I'm using a 15" Macbook Pro running OSX6.8 and cannot upgrade. I have a subscription to Adobe CC but none of these work on this so I was on with Adobe for 5 hours trying to install and launch Illustrator, InDesign, Photoshop, Muse, and Acrobat Pro from CS6. Well, InDesign is the only one that works and I have a ton of work due! I don't have a serial number for Photoshop or Illustrator except for CS3, and they don't work. InDesign gave me no problems. Illustrator says it can't work on this machine. Photoshop needs a serial number. I'm stumped and getting anxious and freaked out. Can anyone help? Adobe Chat is down right now.

    if you have a cc subscription, close ps > sign out and then back in to your cc desktop > open ps.
    ai cs6 requires:
    Multicore Intel processor with 64-bit support
    Mac OS X v10.6.8 or v10.7. Adobe Creative Suite 5, CS5.5, and CS6 applications support Mac OS X v10.8 and v10.9 when installed on Intel-based systems.*
    2 GB of RAM (8 GB recommended)
    2 GB of available hard-disk space for installation; additional free space required during installation (cannot install on a volume that uses a case-sensitive file system or on removable flash storage devices)
