  • I have downloaded OSX v10.7 lion and i still can't get it to work I need help!!!

    I have downloaded OSX v.10.7 Lion 3 times...I have gone through all the steps downloaded installed everything and re started my computer and each time it does nothing! I am sick of this and really starting to hate my brand new " MacBookPro"....My family has been switching to apple but I am going to tell them not to if I have to deal with this every single time..this is RIDICULOUS!!! Isn't the point of apple to have Lion?---so ANNOYING PLEASE HELP!!!!

    If its brand new it should have come with Lion already installed. Up the top menu click on the Apple symbol on the left and see what system it is running, eg. 10.6.8.  10.7.3. etc.

    Changing the extention name will not help. You either need to use a Video od Media converter or else download and use VLC Player (free) which plays many video formats that Quicktime cannot.

  • Updated Mac Air to Mountain Lion and now I can not create new email in Hot Mail

    Updated Mac Air to Mountain Lion and now I can not create new email in Hot Mail

    Greetings,
         What you posted is rather vague. By doesn't work do you mean the applications don't open at all or are you getting a message stating that your product needs activation? If it's product activation then that is something that Microsoft will have to assist you with. If your problem is that the applications simply won't open you may have to uninstall and reinstall Office again. This is common on the Windows platform too. Rarely when you upgrade to a new OS Office sometimes has an issue with the upgrade and won't open correctly. I would suggest merely uninstalling and reinstalling. Nine times out of ten that helps.

    Hi janet,
    Software that runs on your Mac cannot run on your iDevices. Different operating systems. You will have to go to the App Store on your iPad to see if you can find the equivalent software for your device.

    I have tried safe mode boot, NVRAM and PRAM reset but no luck...

    First, try a Safe Mode boot.
    Startup your Mac in Safe Mode
    A Safe Mode boot takes a longer than a normal boot so be patient.
    Once you are in Safe Mode, click Restart from your Apple () menu.
    If that didn't help, reintall OS X..
    Restart your Mac while holding down the Command + R keys so you can access the built-in utilities in OS X Recovery

  • I just downloaded the new Mac OS X v10.7 Lion, and now when I go on the Mac Store

    I just downloaded the new Mac OS X v10.7 Lion, and now when I go on the Mac Store to download a game (N.O.V.A 2) it goes straight to the Launch Pad, as it's supposed to, but the game it's self wont download, it just keeps saying "waiting" I never had this problem before, any ideas?

    I'm connected through my Sky Wifi, it's extremely quick, and I don't have any problems with it. Yes it asked me for my Account Email, and password as normal, then it did that little annimation where it flys into the Launch Pad, then it's saying "waiting" where it should be saying downloading.

    Lion is a bit of a memory hog - kernel_task will use quite a bit and Safari is known to use more; you can't do anything about the system, but changing to Firefox may help a little. The best way to deal with it is to increase your RAM; the required minimum is just that: the minimum. My Macbook would keep crashing and beachballing until I upped the RAM to 4 GB. RAM is inexpensive right now - check out OWC (macsales.com) or Crucial.com; both reputable RAM vendors with lifetime warranties. You won't regret it.
    As for iDVD - I purchased the retail iLife 11 disk because of iDVD (because I use that a lot) - it's available at online resellers, the Apple Store, and ebay.

  • I upgraded to Mountain Lion and now I can't use any of my software!

    What a disaster and huge mistake.  Upgraded to Mountain Lion and now I can't run Autocad 2012 for Mac, any of my Adobe Creative suites software such as Photoshop, Illustrator.. and now I can't even do upgrades because Mountain Lion doesn't allow me to launch DMGs.  I've lost thousands of $'s in software, not to mention time, but most importantly now I can't even work!  I just tried to revert back to Snow Leopard by intalling it back in my hard drive and it won't let me.  I never used Time Machine.  Is there any way on earth I can revert back to my old operating software???  Please help.  And if you haven't upgraded yet and are thinking about it.  BEWARE - and don't do it.  I've been reading that Mountain Lion isn't working with Microsoft applications either.  Omy...I haven't even checked that. 
    and of course no one at Apple support can or will help me

    It's not my Microsoft that I use much or am worried about.  I can't run AutoCAD.  and I can't update AutoCAD either.  When I try to mount an update just to get it working, it says it can't run the DMG file.  Apparantly this new platform doesn't use Rosetta - which is needed to run any of these updates or downloads.  ***?  and then When I try to open CS4 appliations - Adobe Photoshop, Illustrator, or InDesign - I get the message "Licensing for this product has stopped working - Error 150:30 - ***? 
    So basically I can't use ANY of the programs I ran before.  And yes I have googled desperately all day.  Adobe has some suggestions - like deleting a Flex files - which I did...Defragmenting - which I did.  And most importantly provides am Adobe Licensing Repair tool to fix - which I can't open because Mountain Lion won't mount the DMG in order to run it!  It's a complete disaster and I don't have the money or time to purchase and or reinstall everything.  I am just screwed. 
    No you are not, calm down, cbs20 already gave you the answer on opening dmg files, updates are available for most of your programs and I assume you have licenses for the Adobe products. AutoCad you'll have to wait for.
    And please .... Start Backing Things Up, you could lose it all without one, work included.

  • Selling macbook Pro 2011. It came with Lion, I upgraded to mountain Lion and Mavericks. Can license be transfer to new owner? how?

    selling macbook Pro 2011. It came with Lion, I upgraded to mountain Lion and Mavericks. Can license be transfer to new owner? how?

    Good question now that Mavericks is free to all.
    It used to be - and is probably still the case - that to comply with the license you should erase and re-install the OS that came pre-installed on the Mac when new. If there were restore disks they needed to be passed on with the Mac.
    I'm happy to be corrected on this by someone who's more au fait with the legalese, but an upgraded OS is tied to an AppleID whereas the original OS is tied to the computer, not an AppleID.
    My guess is, that if you launched the Recovery HD, erased the drive using Disk Utility and re-installed the OS, Lion would be installed.
    Be interesting to see what others say.

  • I have the following Apple Computer: Dual 1.25 GHz PowerPC G4, 2 MB per processor. Can I put install new Intel Xeon processors in place of the current ones to bring my Mac up to the MacPro standards and so I can install the new Mac software?

    I have the following Apple Computer: Dual 1.25 GHz PowerPC G4, 2 MB per processor. Can I put install new Intel Xeon processors in place of the current ones to bring my Mac up to the MacPro standards and, if so, can I then install the new Mac software (Lion)?

    As has been clearly stated, no, no, and no.
    If such an upgrade were possible, it probably would be more money than it would be worth.
    If you're running a G4 (dual-processor even) you can pick up a used Mac mini (intel that is, and something from 2010 or newer would be the best bet) that will be screaming fast compared to a G4.
    Once upon a time, processor upgrades were not only possible, but a good deal, and a relatively inexpensive way to get more life out of your Mac. I upgraded a G3 tower to a G4 for  few hundred dollars, and I was glad I went that route at the time. Finally,  CPU upgrades, at least as far as I know, aren't available anymore.
