    You cannot download the upgrade to Snow Leopard.
    Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s MobileMe service; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer)
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
             3. MacBook Pro (Mid/Late 2007 or newer)
             4. MacBook Air (Late 2008 or newer)
             5. Mac mini (Early 2009 or newer)
             6. Mac Pro (Early 2008 or newer)
             7. Xserve (Early 2009)
         Are my applications compatible?
             See App Compatibility Table - RoaringApps.
         Am I eligible for the free upgrade?
             See Apple - Free OS X Mountain Lion upgrade Program.
         For a complete How-To introduction from Apple see Upgrade to OS X Mountain Lion.

  • TS1362 I have a Mac Pro tower, am running osx and iTunes will not work.. It basically just stopped working after having run faultlessly for...years... I can see all the songs, playlists etc, but the progress bar will not progress..it's 'stuck'. Suggestion

    I have a Mac Pro tower am running OSX and iTunes will not work. It has always worked flawlessly. I can see all my iTunes content- my playlists, my songs et cetera, But I cannot play anything. The progress bar is  'stuck'...any suggestions?

    Thanks. I have been using iTunes since its inception and have never had a problem...I'm using the latest version. The progress bar is the bar that moves when you're playing a song..it just won't start when I double click on a song,..have tried quitting, rebooting etc but nothing works. Apple are useless-they have told me twice they've tried to call me 'momentarily', but I've been waiting by the phone, and they definitely have not tried to call...

  • Can I restore my system from install discs when DVD is not working?

    Can I restore my system from install discs when DVD is not working?
    There is a disc jammed in the drive and when I try to do an install in Target Firewire mode using a G5 Tower I get an error saying the software cannot be installed on this machine, before I can even select the iMac's drive. I'm using the grey software install discs that came with the iMac.
    Is my only option to open up the iMac and get the jammed disc out?
    Thanks

    Problem solved - I posted on the general Tiger Discussions as well.
    I had the wrong machine started in Target Firewire mode.

  • After doing last Mavericks update, Messages is not working properly

    Since yesterday, after doing last Mavericks update, Messages is not working properly - the Dock icon is not bouncing nor showing any number for new messages. Very annoying, since I usually have Messages on background while working and I now i don't realize if people is chatting me unless I open the messages wondows.

    Hi,
    Check System Preferences > Notification is set for Messages
    In Messages > Preferences > General Section change the Sound option for Message Received.
    Restart the app and test this sound is (still) playing.
    Place app in background an iMessages "yourself" form your iPhone.
    Does the sound Play ?

  • I've bought a iphone 5c from USA but the headset is not working properly its still in warranty,can i go for replacement of headset??

    I've bought a iphone 5c from USA but the headset is not working properly its still in warranty,can i go for replacement of headset??

    Since it is only the headset that is the problem and not the iPhone it would be better to just buy a new set and not let yourself be frustrated over it.  If you send anything to your sister before the one-year warranty is over, include the headset so she can exchange it at an Apple store.

  • Can no longer access iPhoto from the iMovie camera browser..not working. Also the Inspector tool not working properly. Cannot change clip duration.

    How can I fix the INSPECTOR Tool?   Clip duration is not working properly, it is very erratic.  You type a number and a different one comes up on the clip.
    Suddenly the iPhoto Camera browser in iMovie is not working properly either.  Can not access my iPhotos to include them in iMovie project.

    Have you tried this?
    From the "HOME" screen, go to "SETTINGS > PRIVACY > PHOTOS" and see if iMovie is listed in the "PHOTOS" page. If it is, then tap the iMovie switch to "ON"
    Now your Videos & Photos should be accessible in the iMovie App.

    thanks

    I've been searching old posts about this problem. It started cropping up back in 2006. At least 66 people have posted about this same phenomenon.
    Two posts mentioned possible DIY fixes. Here's their advice (but I haven't tried this myself yet):
    "Hello everybody,
    I have found a solution for my problem, I hope it can help you guys too. I found this following link to get my ipod open:
    http://www.answerbag.com/q_view.php/30180
    When I opened it I discovered that the connection to the little print (?) where you plug in your headphones was loose (it is a piece with both the headphone plug and the hold function). So I simply reconnected it, and voila, my ipod was fixed! Good luck!"
    "I had the same problem and fixed it by following the procedures to opening the mini to replace the battery. Then you will see the CB that the headphones plugs into. This CB (circuit board) plugs into the main ( mother board )
    Mine had worked it's way partly out. I pushed this plug back on securly and the headphones now work. Hope this helps. You can find the instructions for changing the battery by googling changing the battery on a mini IPOD."
    Have no idea if this will truly work. Scary stuff, opening up an iPod . . .

  • I have upgraded to 10.10.3 on my MacBook Pro now the Calendar is not working properly. Help please?!?

    Yesterday I upgraded my MacBook Pro 13" (Early 2013) to 10.10.3. I immediately started having problems with it opening apps slowly. So I read and discovered it had replaced some of my apps with newer versions. I also restarted it 2 or 3 times. That seemed to solve that problem. This morning I get on and it is doing the same thing, but it is limited to the Calendar. Anything I try to do in the Calendar gets me the spinning beachball, from opening it to editing to adding an event. I have many dates and events saved that I don't want to lose. Am I going to have to reinstall the Calendar? If so, how can I do it without losing my content?

    This is the note I sent to the other thread (Macbook is slow since OS X 10.10.3. I'm sorry. I hope this helps
    I did not have a specific category that said "log list" once I got to "All Messages". It just showed "Log" so that is what I am sending you. The other thing is that the timestamp is 9:23:?? the next is 9:34:?? and the problem occurred at 9:32:??. So you are getting the log from 9:23 until it repeats.

  • My ipod 5th generation screen cracked a few months ago or so. Today I went on it and the screen was half black and had red, blue and green lines on it the screen does not work and ive tried to reset it but its still the same what is it? how can i fix it?

    help!!!

    Unless you purchased the optional AppleCare+ extended warranty,
    Apple will exchange your iPod for a refurbished one for (USA) $99 for 16 GB 5G and $149 for the other 5Gs. They do not fix yours.
    Apple - iPod Repair price                                    
    A third-party place like the following maybe less. Google for more.

  • I just got a new MacBook pro and the charger is orange and I can't turn it on but it was green before. What is the problem?

    I have a new MacBook pro that will not turn on as the battery is no longer green. It turns orange why is that ?  I have it plugged into an outlet with the charger as always and it was always green before?

    The adapter light will always turn orange when your machine is charging. It will go back to green when the battery is fully charged.
    Nothing to worry about.

  • Photoshop CS5 on Mac OSX 10.7.5 - Monitor compensation seems to not working properly.

    Hi,
    I've never noticed it before upgrading to Lion.
    Using sRGB as working color setting, if I create a new doc and fill a layer with red (255,0,0), I see Orange color, instead of red. Similarly if I use Adobe RGB 98 as working color setting. I have Photoshop CS3 installed on  virtual machine on Win XP, and I don't have this issue, red is red. If I open in PS CS3 a doc created with this red layer in PS CS5, red is red. Similarly, using GIMP with Adobe RGB 98 as working space, I see a brilliant red.
    If I open a doc with the same red created in Gimp, with PS CS5 and choose "don't manage color" the red remain red. If I choose either Use doc profile (Adobe 98) or convert to profile (sRGB), the same orange come out. It drives me mad!

    This is a screenshot with my square red made in sRGB, with sRGB as working color space, in save for web window without color management.
    This orange is what I see in PS.
    This is what I see with monitor color preview (what I would see with monitor compensation in PS window).
    Anyone got any idea of what's the problem?
    Thank you
