How To Fix App Problem With Apple macOS Catalina

Now that macOS Catalina had been released, Apple offers a wide range of new features and app improvements. While installing and using the new macOS Catalina is not working perfect for some, problems and issues have been experienced and reported by other Apple Mac users. 

There has been reports of a wide variety of problems relating to the new macOS Catalina update. Although Catalina introduces a whole new level of iOS Apps to Mac users, older apps will no longer work on macOS Catalina. This means that with the release of Catalina, the previous 32-bit apps will be replaced with a 64-bit (Intel) app,. Basically means switching to a 64-bit (Intel) app,. The error will appear once an app is being launched an error prompt appears “App needs to be updated” “the developer of this app needs to update it to work with this version of macOS. Contact the developer for more information”. Hence, the new Mac Operating System has ended support for all 32-bit apps. 


To be able to know if your existing app is still on a 32-bit or 64-bit (Intel) app, follow these steps:

  1. Click on the Apple icon located at the top left corner of your Mac Screen.
  2. Click on “About” This tab
  3. Select and Click System Report
  4. Once System Report is selected, scroll down from the list of options and select Software.
  5. Under Software section, click on Applications. A list of apps will then appear. You will when you click an app its Application name, Version, where it was obtained (most of the time from Apple) and last Modified.
  6. Click on each App to check if it is a 32-bit app or a 64-bit (Intel) app

When at times you launched an app and a prompt error message appears as mentioned above, the first thing to do is to check that app has an available update to download. You can either check for updates using the app or on the developers website if the app has a website. The only solution to this App problem is to update your apps to be able to use it with macOS Catalina.

Most of the time when switching from 32-bit app to 64-bit (Intel) app,, the updated app will be free of charge. But in some, this is not the case as with some app developers are not charging the update. Thus you may need to spend to be able to buy an updated version of the app. Although you can also try to find a free of charge apps as an alternative that still performs the same function but now on a 64-bit (Intel) app
