With a good 2,97 GB, the new update to macOS 10.15.4 is definitely not just a small bug fix, but a jump to a new version that also brings some new functions. What is new in detail can be found below in the changelog of the update that I copied from the installation window. The most important things in brief are right here:
The most important new features of 10.15.4
- Sharing folders in iCloud Drive with other people
- New function in the accessibility features, which allows the mouse pointer to be controlled by moving the head
- Lyrics are now displayed in real time, just like you know from iOS
- Universal apps: If you buy an app on the Mac, you automatically receive the version for the iPad or iPhone - or vice versa
The update of macOS is started via the system settings, which can usually be found in the dock.
How do I start the Mac update to macOS Catalina 10.15.4?
If you are still looking for macOS updates in the App Store, you are now on the wrong track, because Apple has placed the software updates for the operating system - as before - in the system settings. Here there is the button "Software update", which after a click also checks immediately whether a new update is available and suggests its installation.
You can find software updates for macOS via the system settings in the Finder.

My recommendation for this update - install it or not?
After the first versions of Catalina caused quite a bit of chaos (take a look at this collection of Catalina problems), Apple seems to have fixed the worst bugs and to be able to concentrate on new functions.
When it comes to the question of whether you should install the update, I am always relatively confident with such "high" version numbers and would say that you can access this without hesitation. Due to the many reports from users who are still having problems with Catalina, I would definitely recommend a 1: 1 backup with Smart backup, Carbon Copy Cloner or Super Duper before performing the update.
I only got these warning windows after restarting macOS 10.15.4. The corresponding system extensions are part of software that I haven't used for ages, so it is not a problem if I remove them.
In my case, the update took a good 25 minutes to install. After the restart came three new ones Warning messages about outdated system extensions high, which you could simply click away with "OK". So far everything has been stable for me, so I see no reason to warn you about the update.
If you installed the update and ran into problems, please leave a comment here for other readers to know.
