Apple has been busy rolling out the new iPhone 11 and 11 Pro iPads, the new Apple Arcade gaming service Apple Watch Series 5 smartwatches and Apple TV Plus . And now, without missing a step, it is released Catalina the latest version of the MacOS.

With Catalina Apple replaces the iTunes app with three separate apps: Apple Music Apple Podcasts and Apple TV. Perhaps just as useful, have the revision let Mac users run iPad apps that they can download from the Mac App Store and use a iPad as a second screen, much like you have a monitor. And with Catalina, Mac users can now look at Apple Arcade .

If you can't wait to get hold of Apple's new operating system, you can download and install Catalina as follows.

Check if you can run Catalina

First check if you can install the new operating system before you start. The hardware requirements of Catalina remain the same as for MacOS Mojave, the current version of the operating system, so if you can run Mojave, you can also use Catalina. These are the Macs that meet the requirements:

To check which Mac you have, choose About this Mac from the Apple menu. The Overview tab indicates which Mac you have.

Before you install Catalina …

Before you download and install the MacOS update, make sure the transition to Catalina is as smooth as possible.

Make a backup. Before you download and install a major MacOS update, you must make a good, current backup of the contents of your Mac drive, in case something goes south during the installation or afterwards and you must go back. You can use the Mac's built-in Time Machine backup utility or grab a Mac backup app such as Carbon Copy Cloner.

Know your Apple ID. If you are a Mac user, you probably have an Apple ID. If not, buy one, because you probably need it during the Catalina installation process and logging in to iCloud.

Check your free storage space. The download is large – about 6.5 GB – and Apple said you should probably have about 20 GB of free storage space to install Catalina.

Update your apps. With Catalina, Apple disables support for 32-bit apps. What that means is, if you have an older app that you are still using – for example, Microsoft Office 11 for Mac – make sure that you have a 64-bit version of the app before moving to Catalina. If this is not the case, you must find a replacement or stay with your current MacOS so that you can continue to use the software.

Ready? Download and install

After you have completed your preparations, you can download and install Catalina.

1. Go to the Mac App Store and tap Updates in the left sidebar. If Catalina is available, you should see the new operating system. You can also search for "Catalina" in the store if you don't see it. If that doesn't work, choose About this Mac from the Apple menu and tap Software update to see if it appears. If you still don't see it, Apple may be doing a staggered update, so be patient while it rolls out.

2. Tap the Update – or Get – button to download the update.

3. Follow the installation instructions to complete the installation.
