macOS Catalina – What Could be the Problem?

Not quite familiar and intimidating, a message may appear stating that in the new version of the OS, the developers decided to completely abandon 32-bit applications. Absolutely all third-party system and popular programs have long switched to 64-bit.

The system will give you a list of unsupported services. There is nothing terrible in this, any of them can be replaced by another analog. However, he will need to find and get used to the new interface.

In order to find such programs at home and find a replacement in advance, go to the Apple menu -> About This Mac -> System Report -> Software -> Applications.

Sort the applications by the 64-bit column in the upper right corner, after which a “No” note will appear in some. These will be the applications with which difficulties may arise after the transition to macOS Catalina.


If you already want to try these innovations for yourself, nobody forbids trying a new system. There is a high chance that you, like me, will not want to return to Mojave. Therefore, I wish the bold a successful update, and to everyone else a speedy release.
