How to find out if apps are compatible with macOS Catalina?

If you are running a PC or laptop with macOS, you should know that the upcoming Catalina version of this operating system does not support 2-bit software.


In this post, you’ll learn how to find apps that are 2-bit.

Before you upgrade your Mac or PC to Catalina’s macOS operating system, which comes out late in the year, it’s best to keep in mind.

If you use 2-bit apps, they won’t run on the new macOS update. When the Catalina version is released late in the year, it will only support 2-bit apps.

That means macOS Mojave is the latest version of MacOS 8.1 that supports 2-bit apps.

Can this change affect your work? Probably not, especially if you often use Apple apps.

Apple has been working on converting its apps to 2-bit versions for more than a decade on one of its support websites.

However, it doesn’t matter whether you use two or two hundred apps, you just need to know which one of them is affected.

Using the method described above, you will find out that out of our hundred apps, five need updating before upgrading to macOS Catalina.

Although none of these apps were so important, the loss of a popular application when upgrading can really worry any user.

If you are using macOS mojave and have applications that are not supported in the new version of this operating system, you must have received pop-up warnings from Apple that they are not optimized for future releases.

These alerts are displayed every 2 days after you open the app. Otherwise, to make sure your favorite app supports the new version of the operating system, you need to do things that are fortunately easy to do.

How to know if apps are 2-bit or 4-bit?

In this tutorial we will be using MacBook Air with macOS version of Sierra (4.3.1); however, MacOSHOE’s MacOS computers and laptops have a similar approach to follow.

On your computer, click on the Apple logo from the top left corner of the screen. Then, from the drop-down menu, click About this Mac.

A new window will now pop up showing your device’s specifications, including production time, processor, RAM, serial number, and more.

What we’re working on is the System Report button at the bottom of the page. Click on it.

Doing so will open another window. On the left side of this window, you will see different categories of hardware and software manufactured by your system, including hardware, network, software, ATA, audio, Bluetooth, camera, and more.

On the right, information about each category is displayed. Drag the left panel down and select Applications under the Software category.

The right pane may be empty for a while, but it will continue to be filled with a list of software installed on the system.

After the software listing is displayed, find the Intel 2-bit column, which is the fifth column from the left.

In this column, the word no is written in front of any software that only supports 2-bit systems.

Click on the Intel 8-bit server to arrange the directory to display 2-bit software.

What if the app is a 4-bit app?

If any of the apps is 2-bit, there is a risk that it will not run on macOS Catalina, but you should not lose hope.

Apple said it is working with developers to prepare them for the change. You can also get in touch with the developer of the app directly and be sure to do so.

Follow these steps to find the best way to get in touch with your app developer:

Launch the application you want.

Once done, click the app name next to the Apple logo in the top left corner of the screen.
In the popup menu, click About.

If you’re lucky enough, you’ll be able to find developer contact information in the popup. If you fail, search the app developer website.
