I am using MacosX 10.7.5 on my computer should I upgrade to mountain lion or maverick or Yosemite

I am using Mac10.7.5 and am thinking of upgrading to Mountain lion, Maverick, or Yosemite. I am running Safari 6.1.6 and I am afraid I will lose stuff with upgrade or become non compatible. Would like to know what to do.

Back up your data and check your applications for compatibility before upgrading.

  • HT1443 using MACOSX 10.5.8, on a late 2007 macbookpro, can I upgrade to Mountain lion??

    I'm using a macbook pro late 2007 running osx 10.5.8, can I how do I upgrade to Mountain lion??
    Having difficulty sourcing snow leopard....

    If you go to http://www.apple.com/osx and then to the Tech Specs page (upper right) you will get a listing of supported hardware...that will tell you if your MBP will run Mountain Lion.

    If you purchased Lion for your iMac, just log into the Mac App Store from your MacBook using the Apple ID under which you purchased Lion and go to the Purchases page. You will be able to download and install Lion there. 
    searching the internet i found a link to upgrtade to 10.7
    The only place you get get Lion is from the Mac App Store. If you found some other site, that was an illegal copy and almost certainly tied to someone else's Apple ID and hence unusable by you. If the link was just to the Mac App Store, see above.
    As to the problem with synchronization to iCloud, that's not a 10.6 question, so I'd suggest you take up that specific issue in either the Lion or iCloud forums, providing full details, and someone there can probably help you sort things out.
    Regards.

  • After upgrading to Mountain Lion, I cannot open my File Maker Pro files. Can I use Numbers to open these files?

    After upgrading to Mountain Lion, I cannot open my File Maker Pro files. Can I use Numbers to open these files?

    Numbers is a spreadsheet program and FileMaker is a database program, so you probably can't use Numbers to open them unless you had first exported them from FileMaker in a spreadsheet-compatible format.
    If you upgraded from 10.6 Snow Leopard or earlier and your old copy of FileMaker won't open anymore, it might be a PowerPC application that is not compatible with 10.7 and later. If that is the case, to work with your FileMaker files you should upgrade your copy of FileMaker to the latest version, which seems to be FileMaker 12.

  • After upgrading to mountain lion, the movies I create using iDVD periodically stop then resume abruptly when I play them back on my DVD player. Any ideas on correcting this?

    After upgrading to mountain lion, the movies/slideshows I create using iDVD playback in a jolting start/stop manner. This didn't happen with the prior os - playbacks were flawless. Any ideas, short of uninstalling mountain lion, on how to correct?

    I know this is not much help. IDVD and Mountain Lion are working perfectly for me.  I know many others that use Mountain Lion with iDVD also.
    I think your problem lies elsewhere.

  • After upgrading to mountain lion I cannot use my HD TV as a display through my thunder port and HDMI cable ???

    after upgrading to mountain lion I cannot use my HD TV as a display anymore using thunderport and HDMI , which worked before , does this mean I have to buy apple tv to mirror onto my HD TV

    can it be something related to wi-fi?  I have read other posts talking about loss of connection using wifi.  I'm connecting my G5 through an airport express which is expanding my wifi generated from my Apple Time Capsule. It is quite difficult for me to relocate the server close to the Time Capsule and vice versa but if it works, at least that would be something.  It was working with Lion about 3 months ago - showing up in Finder, etc.

  • After upgrading to Mountain Lion, I can't delete/move emails using Mail app

    I upgraded to Mountain Lion from Snow Leopard and having problems with my Mail application.
    The long and short of it is that I cannot delete or move emails from my Inbox.  When I select an email in the preview panel and delete it, it disappears, but when I select the Trash folder, it isn't in there.  And when I go back to my Inbox, lo and behold, it is back there again, as if I had never deleted it.  The same holds true when I try to move an email from my Inbox to one of my iCloud folders.
    Emails come in to my Inbox just fine.
    And I am able to move emails from one iCloud folder to another, however.
    And I do not have this problem when I access my email via Iphone, ipad or icloud.com.  In fact, when I delete an email from my iphone, it gets deleted from my Inbox on my Mail app.
    I looked in Mail Preferences, and I have one Account set up:   iCloud IMAP.   Is that right?  I use me.com for my email.
    Any ideas here?

    This means that at some time you had the iWork ’09 trial installed. You need to delete the trial & then reinstall from the boxed DVD or the Mac App Store. The files to delete are the iWork ’09 folder from the main HD > Applications; the iWork ’09 folder in HD > Library > Application Support & the individual iWork application plist files found in HD > Users > (your account) > Library > Preferences for each user. Yvan Koenig has written an AppleScript that removes the files. You can find it on his box.com account in for_iWork'09 > other_iWork'09 items > uninstall iWork '09.zip.

  • 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.

  • Just want to ask about the full screen icon that used to be on the play bar but seems to have disappeared since upgrade to mountain lion, any way to get it back?

    Since upgrading to mountain lion I've noticed the full screen icon which used to be on the playback bar in quicktime has gone, I know you can go to the menus to make it full screen but if you're watching something online like with apple trailers I can't seem to make them fullscreen anymore, is it me or have they just taken this option away now?

    I've been playing the trailers in my browser and the full screen option has gone for me,
    As already stated, the icon was replaced by the "Share" pop-up menu icon in the same location.
    and the command-f keys don't work either when I'm playing in a browser and it's truly only been since I upgraded to mountain lion.
    Strange! It works for me. Here is a link to a screen recording of me wayching a trailer in Safari and later watching a trailer download. In both cases the trailer could be expsnded for full screen viewing and then reduced back to the size of the original 720p player display screen. If you can't do this then you may have a player problem also.

    Why did apple make these changes when they worked perfectly the old way, I mean if it ain't broke don't fix it!
    Only Apple whould know for sure but my guess would be that other users may have requested the "Share" pop-up more. Makes no difference to me because I normally use the key shortcuts anyway.

  • Upgraded to Mountain Lion, can no longer use airplay

    Last week I purchased Apple TV (I believe its 3rd Gen) and had it all working fine, until I decided to be 'clever' and upgrade to Mountain Lion so I could use the mirroring in AirPlay. Prior to the upgrade I could stream brilliantly through itunes, including movies, to the tv via our Apple TV.
    After the upgrade iTunes intially kept popping up every time I would attempt to play a movie through airplay and say it couldn't find the Apple TV. After a few hours of pulling my hair out, restoring the Apple TV, restarting my MacBook a million times and whacking the keyboard for effect - the AirPlay icon has now totalling disappeared from iTunes. After a bit of investigation, I discovered that my Mac is actually mid 2010 and thus I understand incapable of mirroring through Mountain Lion! I've read that uninstalling Mountain Lion is actually more a case of wiping my laptop and starting again. I'm really hoping to avoid that!!
    Is there a way I can still use AirPlay in iTunes with Mountain Lion and if so I'd appreciate some direction on how to get it working.

    fixed - found out I had to turn off IGMP Proxy in my FiOS home router.  Why, I don't know.

  • I have upgraded to Mountain Lion and have found that some of my software no longer works, notably Image Browser and also the Epson Scanner Perfection 3490 software. Is there a 'patch' or way to allow me to use these programmes especially the scanner.

    I have upgraded to Mountain Lion and have found that some of my software no longer works, notably Image Browser and also the Epson Scanner Perfection 3490 software. Is there a 'patch' or way to allow me to use these programmes especially the scanner.

    Apple discontinued support for PowerPC apps with Lion, I think, so you're out of luck there. No patch coming, unfortunately. Best to upgrade whatever old applications you have or, since it seems like you're using some relatively old software, scout around for replacements that give you the functionality you need.
    Go to Apple menu > System Preferences > Print & Scan and select your scanner from the list--if it's not there you'll need to add it (start with the little plus icon). Once you have it in the list you can click on the Open Scanner button and a pretty barebones scanner driver will load for you. But Image Capture (as mentioned previously), found in your Applications folder, will probably do the job as adequately, or better, than your old scanner software.

  • I had Leopard on may Mac. I upgraded to Mountain Lion using Snow Leopard. I can't use my video with Mountain Lion. Can I load Snow Leopard on an external hard drive so I can use it with my camera?

    I had Leopard on may Mac. I upgraded to Mountain Lion using Snow Leopard. I can't use my video with Mountain Lion. Can I load Snow Leopard on an external hard drive so I can use it with my camera?

    First, you cannot do this if you have a Boot Camp partition.
    Second: Create a new partition.
    1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
    2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
    3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)
    4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
    You should now have a new volume on the drive.
    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.
    Third: Install Snow Leopard.
    Boot from your Snow Leopard DVD. Follow instructions for installation being sure that before you actually install Snow Leopard you have selected the new partition as your target destination.
    Booting From An OS X Installer Disc
      1. Insert OS X Installer Disc into the optical drive.
      2. Restart the computer.
      3. Immediately after the chime press and hold down the "C" key.
      4. Release the key when the spinning gear below the dark gray Apple logo
          appears.
      5. Wait for installer to finish loading.

  • I am using Leopard but need  Mountain Lion for the Mac App Store.  How do I get Snow Leopard to be able to upgrade to Mountain Lion?

    I am currently using Leopard but need Snow Leopard to be able to get Mountain Lion. I can see this is no longer available from Apple.  How would I get it so I could then get Mountain Lion. I want the Logic 9 Mac App Store App as I don't want to have to buy the whole Logc 9 from Studio 8.
    Some help would be much appreciated.
    Thanks

  • I just upgraded to mountain lion. I am unable to use airplay mirroring through my apple tv. They are both on the same network. It says a airplay icon should appear in the menu bar but it isn't there. What am I missing here?
