OS version

Hi all

When I go on the apple logo and select "about this mac", I see it says "version 10.10.5."

Just out of curiosity, that each of these figures represents?

Thank you

The top 10 is part of the name, that is, Mac OS X. X being the Roman numeral for ten. Its significance is that the architecture of previous operating system went up to version 9, so it was a new beginning.

The next 10 is version major version number. It is the tenth major release of Mac OS X.

The last digit is the version number of the 'point', one-off releases are updated minor, usually to fix bugs or add small new features.

The most recent version is Mac OS X 10.11.5, named El Capitan.

  • Cannot move Mac OS BETA to final version

    I am currently Mac OS version BETA Sierra 10.12.1 Beta (16B2338c)

    I downloaded the final version of macOS Sierra on the app store and attempted to install in addition to the BETA version.

    The error I get is:

    "Impossible to pass this version of macOS because a newer version is installed."

    Which I don't think it is unless the beta continued after launch. If yes how to install the version on it.

    It is a late-2011 macbook pro, but I doubt it makes a difference.

    Thank you

    The beta version is interrupted, and there apparently on your Mac because it is 10.12.1.

    No matter when you want to go to a previous version of the OS, you need to wipe the drive and reinstall. It's not a way to install on a later operating system.

  • How can I download new version of iwork

    I need help downloading the new version of iwork with enforcement pages

    Downloading applications is done via the Mac App Store. New versions of iWork applications require Sierra, this is why you must first update your operating system to Sierra if you have not already done so. Upgrade to sierra is also done via the Mac App Store.

    Thus, it would be useful to know what version of Mac OS X you are using and what version of Pages that you use.

  • Should I buy now FCPX if a new version may be on its way at the end of October?

    I'm considering the purchase of FCPX at level of iMovie, because I must be able to work with multiple cameras and work with more than one PIP at a time.  Also I'm not a power user in anyway...

    In any case looking around, I see rumors of a possible major new version announced in late October.  I don't know about how the purchase and update of FCPX works so if I had to buy now, I would be able to upgrade to the new version (assuming that it is a major release) or would I have to pay all over again?  Could I be better waiting four weeks until the end of the month?

    What do you think?

    I would like to know.  I have to pay for future improvements.  At the end of the 1990s, Adobe Photoshop cost 1299.  You would have to pay to go to Photoshop 5.0 to 6.0, etc.  It was sold to the library at my college, and students got a small discount.  My first digital camera was a pd150.  From interested parties.

  • How can I download pages for el capitan? Only the version of the sierra is available on app store.

    Hello

    I already bought Apple Pages and Numbers for use on an iMac running El Capitan. Now I upgraded my macbook pro to El Capitan and want to update these programs, but on the App Store, I am only offered a newer version, which requires the Sierra. How can I get the version I need? Thank you, Robert

    Have you tried clicking on the icon in the Mac App Store to see what is happening? In the past, the Mac App Store will say that version will not run on your operating system & offer to download the latest compatible version. I don't think this has changed, but I don't have a Mac in El Capitan to try.

  • iTunes requires a newer Version of Apple Mobile Device Support

    I recently had a problem with iTunes not recognizing my iPhone, so I reinstalled the latest version of iTunes on my PC. Since then I have now received this error:

    iTunes requires a newer version of Apple Mobile Device Support. Please uninstall iTunes and Apple Mobile Device Support, then reinstall iTunes.

    I followed these steps, only to get the same error. I then stopped Apple Mobile Device Support Services, manually delete the files in c:\ProgramData\Apple\Installer Cache, repair the installation of iTunes and restart services, only to get the same result.

    I use iTunes 12 and 10 Windows.

    Would like to be able to sync my phone again.

    For general advice, see troubleshooting problems with iTunes for Windows updates.

    The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

    Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

    The more information box has direct links with the current and recent if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit - for older video cards) as a workaround for problems with installation or operation, or compatibility with third-party software.

    Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

    See iOS device is not showing in iTunes for Windows , if the device will not connect to iTunes after reinstallation.
