Apple is prone to formally launch macOS Catalina after its iPhone 11 launch event on September 10, and although the new work system for Mac and MacBooks brings many new options, it is also removing 235 applications, suggesting that now it doesn’t be able to run
This is because macOS Catalina now will not help 32-bit applications, so any application that has not passed to 64-bit will stop working.
Applications that can be removed in macOS Catalina include Transmist 4.1.7, 1Password 2.12.2, iStats Menu 2.9 and QuickBooks 2015. You may be able to see the full list of applications in The Tape Drive.
While most applications will have 64-bit updates, there may be many that don’t, which is dangerous information if it depends on them and improves macOS Catalina.
What must you do?
In case you are involved that an application you depend on now will not work on macOS Catalina, you should verify that you probably have a 32-bit application on your system.
To do so, click on the Apple icon at the top of the screen and then select “About this Mac.” Click on “System Report” and then go to the “Software” part.
Click on “Applications” and you will also see a list of applications. There may be a column called “64 bits (Intel)”. If an application has “No” in that column, it means that it will not be supported in macOS Catalina.
You can possibly check the list in The Tape Drive accordingly to see if your applications are there.
In case you have 32-bit applications installed, you should check if there is a 64-bit model (if the application has an Internet site, you must indicate if it can be obtained or not).
Otherwise, you will want to find an alternative application that performs the same performance but is 64-bit. Our information for the best Mac applications will help you.
