The app looks interesting, and I understand from your replies that it's compatible with OS X 10.6.8 (Snow Leopard). Since the name is LINGVO (Esperanto for 'language'), I wonder if there will be add-ins for the dictionaries, including -perhaps- Esperanto? Mac OS X & macOS names. As you can see from the list above, with the exception of the first OS X beta, all versions of the Mac operating system from 2001 to 2012 were all named after big cats. Earlier versions of Mac OS have been around since the mid-1980s. Apple released the first version of OS X in 2001. There have been many versions of OS X since then, but the most recent ones include High Sierra (to be released in 2017), Sierra (2016).El Capitan (2015), and Yosemite (2014). In recent versions, Apple has rebranded OS X as macOS (for example, macOS Mojave).

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.

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.

When you upgrade to macOS Catalina, you get more of everything you love about Mac. Experience dedicated apps for music, TV, and podcasts. Smart new features in the apps you use every day. And Sidecar, which lets you use iPad as a second Mac display. Best of all, upgrading is free and easy.

Chances are, your Mac can run macOS Catalina.

Mac computers with Metal-capable graphics processors (GPUs) can upgrade to macOS Catalina.

Make sure you’re ready to upgrade.

Before you upgrade, we recommend that you back up your Mac. Then, if your Mac is running OS X Mavericks 10.9 or later, you can upgrade directly to macOS Catalina.

Upgrading is free. And easier than you think.

Upgrading from macOS Mojave?

Go to Software Update in System Preferences to find the macOS Catalina upgrade. Click Upgrade Now and follow the onscreen instructions to begin your upgrade. If you don’t have broadband access, you can upgrade your Mac at any Apple Store.

Upgrading from an older version of macOS?

If you’re running High Sierra (10.13), Sierra (10.12), or El Capitan (10.11), upgrade to macOS Catalina from the App Store. If you’re running Lion (10.7) or Mountain Lion (10.8), you will need to upgrade to El Capitan (10.11) first. If you don’t have broadband access, you can upgrade your Mac at any Apple Store.
