How to find out which apps in macOS will soon lose support

If you don't already know, the macOS High Sierra operating system is the last version of macOS that supports 64-bit applications alongside 32-bit applications. The new beta versions of macOS High Sierra 10.13.4 have already started to slowly alert users to the fact that they can use some 32-bit applications that will soon lose support. Although Apple will not ban 32-bit applications so that you will not be able to use them, they will only remove support for them. This simply means that these apps may not work 100%. If you want to find out what applications are running in 32-bit version on your Mac or MacBook, there is an option through a simple utility.

How to find out which apps are 32-bit

The easiest way to find out which applications are 32-bit is through the v Information about the system. How do we get here?

• Hold down the button on the keyboard Option ⌥
• With the key pressed, we click on apple logo v upper left corner screens
• With the Option key still pressed, click on the first option – System Information…
• Now we can release the Option key
• In the System Information utility, click the item in the left menu Application (located under the group Software)
• We will see all the applications that are running on our device
• You can find out whether certain applications work on 64-bit architecture in the column 64-bit (Intel)
• If there is "Yes" in this column for a certain application, then this application works on 64 bits. If there is "No" in the column, the application works on 32 bits.

Do 32-bit applications currently have any effect on system performance?

As I mentioned in the first paragraph, you won't notice any difference at the moment. But in the future, Apple will 100% want to get rid of all 32-bit applications and replace them with 64-bit ones. Applications working below 32 bits will either simply be disabled or will not work 100% on the device, which will either force application developers to "dig" to 64 bits or users will have to reach for alternatives. It will be very interesting to see how the developers deal with this.
