Will my Mac run macOS Catalina?

According to Apple, the oldest Macs to support macOS Catalina will be the ones from mid 2012. This includes iMacs and even Mac Minis released in late 2012.

Storage Space: 15 GB of free space

Space issues is the most crucial, though. The 15 GB of storage is a formal requirement but in reality, you’ll need twice as much to prepare the backup.

After downloading the update you will discover several new features.

You can download the latest version of the macOS from the App Store. The process is not difficult but requires some preparation. Here's a comprehensive guide on how to upgrade to macOS Catalina.


What are the new features in macOS Catalina?

macOS Catalina — named after California’s Catalina island, in keeping with Apple’s recent tradition of naming new versions of macOS after California landmarks — is a ‘full’ version upgrade. Some classic macOS features have been abandoned, some fully redesigned. No matter how hard you try, you will not find iTunes on Catalina. At the same time, you’ll see a bunch of newcomer tools, namely Music, Podcasts, and Apple TV.

The death of iTunes

Once considered revolutionary, iTunes has been tossed away in favor of Music, Podcasts, and Apple TV . About time, right? These new apps much better fit with music tendencies in 2019. For example, Apple TV is about to rival Netflix, offering hiqh-quality streaming content for $4.99 per month. And you can watch that on any screen rigged up to an Apple device.

Ride your Sidecar

Sidecar is a technology that allows you to use an iPad as a second screen. Who wouldn’t want to double their workspace? No sane video designer would miss such a treat. Your Apple Pencil will come in handy too as you can mark documents and draw on the iPad.

Apple has long been developing something with a code name “Project Catalyst.” Such merging of ecosystems should open the possibility to use iPad apps on Mac. This process is now far from perfect and configuring your iPad apps to run on macOS still requires a lot of clicks. Nevertheless, this is a move in a right direction.


Voice control makes using a Mac completely clickless. macOS Catalina improves dictation and other text instruments, like navigation inside apps.

The Gatekeeper cracks down on privacy

Privacy is a holy cow of our times. Every new macOS system is claimed to be more secure and less prone to hacking. macOS Catalina is not exempt. With its extended Gatekeeper technology your Mac gets doubly suspicious of third-party apps. Apple calls this “notarization” and only those apps that are notarized can flawlessly pass through the installation. For example, CleanMyMac X is an Apple-notarized app, and in contrast to other Mac cleaners, will be installed without a prior warning on Catalina.


When was the last time you used a Dashboard widget? If you can’t remember, you’re not going to miss Dashboard in macOS Catalina. You’ve heard it right: it’s been fully removed in the new macOS. Goodbye, Dashboard, on your lonely way to history, you’ve got iTunes as a company.

64-bit applications

Latest Version Of Macintosh Operating System

Before macOS Catalina, the 32-bit / 64-bit app distinction was known only to programmers. These numbers represent different types of app architecture. Starting macOS Catalina, 32-bit apps will no longer be supported on Macs. For many users this will be the single reason to avoid it and stay with good ol’ Mojave. Some big name applications, are still yet to be optimized for Catalina and 64-bit.

If you’re still planning to upgrade, there are tools to make the transition less painful. For example, the Mac problem-fixing tool, CleanMyMac X, has an Updater feature. It checks how many 32-bits you have and updates them to newer versions (if such are available).
