Hello raj.singh25
Jul 20, 2017 When I checked my system 'about this Mac' it says. Software Mac OS X Lion 10.7.5 (11G63) And, When I opened Appstore to update one of the software is saying 'macos Sierra' utilities: Installed. So, is it Lion or Sierra? I just need to update from Mac OS X Lion 10.7.5 (11G63) to latest version. Thank you for your help.-Kuldeep.
Welcome to Apple Support Communities.
If I'm understanding correctly, several apps are not working because you need to update your macOS. I will be happy to help you with this. Your current version of macOS can be updated to macOS Sierra.
Take a look at the information below to ensure that you meet all of the other necessary system requirements to upgrade to macOS Sierra, from our article: How to get macOS Sierra
Mac Software Update 10.9
Can your Mac use Sierra?
macOS Sierra requires one of the following Mac models and versions of OS X. It also requires at least 2GB of memory and 8.8GB of storage space.
- iMac (Late 2009 or newer)
- MacBook (Late 2009 or newer)
- MacBook Pro (Mid 2010 or newer)
- MacBook Air (Late 2010 or newer)
- Mac mini (Mid 2010 or newer)
- Mac Pro (Mid 2010 or newer)
- OS X El Capitan v10.11
- OS X Yosemite v10.10
- OS X Mavericks v10.9
- OS X Mountain Lion v10.8
- OS X Lion v10.7
To find your model, memory, storage, and version of OS X, choose About This Mac from the Apple menu ().
Get Sierra from the App Store
Before upgrading, it's a good idea to back up your Mac. Then follow these steps:
- Open the App Store app on your Mac.
- Search the App Store for macOS Sierra, or go directly to the macOS Sierra page.
- Click the Download button on the macOS Sierra page. A file named Install macOS Sierra downloads to your Applications folder.
- After download is complete, Install macOS Sierra opens automatically. (You can also open it from the Applications folder, Launchpad, or Spotlight.) Click Continue and follow the onscreen instructions.

Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some other product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.
If your macOS isn't up to date, you may be able to update to a later version.
Which macOS version is installed?
From the Apple menu in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Mojave, followed by its version number. If you need to know the build number as well, click the version number to see it.
This example shows macOS Catalina version 10.15 build 19A583.
Mac Os 10.8 Update Free
Which macOS version is the latest?
These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Catalina. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.
If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
