How to Check Your Mac for 32-Bit Applications that Will Stop Working After High Sierra
With the release of macOS High Sierra, Apple is discontinuing support for 32-bit applications, which means certain applications and games may no longer be compatible with your Mac. This can be a major inconvenience, especially if you rely on a particular program for your daily tasks. Fortunately, there is a way to check which applications on your Mac are 32-bit, so you can take steps to find an alternative if needed.
What is a 32-bit Application?
Before we get into how to check for 32-bit applications, it’s important to understand what a 32-bit application is. Simply put, a 32-bit application is an application or game that is written using 32-bit instructions. These instructions are executed by the computer’s processor, and the number of bits used determines how much memory (RAM) the application can access.
In the past, most applications were written using 32-bit instructions, but as computing power has increased, more and more applications are being written using 64-bit instructions, which can access more memory than 32-bit applications. As a result, Apple is transitioning to 64-bit applications and is no longer supporting 32-bit applications.
How to Check for 32-bit Applications
The good news is that it’s easy to check which applications on your Mac are 32-bit. All you need to do is open the “About This Mac” window, which can be accessed by clicking the Apple menu in the upper-left corner of your screen.
Once the window is open, click the “System Report” button. This will open the System Information window, which contains detailed information about your Mac.
Next, select the “Applications” option from the sidebar. This will show you a list of all the applications installed on your Mac, including the version number and whether or not the application is 32-bit or 64-bit.
You can also check for 32-bit applications by using the command line. To do this, open the Terminal application and type the following command:
system_profiler SPApplicationsDataType | grep "64-bit (Intel)"
This will display a list of all the applications that are 64-bit, and will also list any 32-bit applications.
What to Do If You Find 32-Bit Applications
If you find any 32-bit applications on your Mac, the first thing you should do is contact the developer of the application to see if they have released a 64-bit version. If the developer has released a 64-bit version, you should download and install it as soon as possible.
If the developer has not released a 64-bit version, your best option is to find an alternative application that is 64-bit compatible. Fortunately, there are many great alternatives available, so you should not have any difficulty finding a suitable replacement.
Conclusion
The transition to 64-bit applications is a necessary step for Apple to take in order to keep up with the ever-increasing computing power. However, for users, this transition can be a bit of an inconvenience, especially if you rely on a particular application that is not yet compatible with 64-bit. Fortunately, it’s easy to check which applications on your Mac are 32-bit, and with a bit of effort, you should be able to find an alternative that is compatible with macOS High Sierra.
