incompatible updates

What MacBook, what age, what OS version are you using. What updates are incompatible, what updates are you looking for.

Those incompatible app updates are because those apps require later versions of macOS.

You can choose to ignore those updates, as will macOS itself.

In Apple macOS usage, upgrades are larger and can be more disruptive and can provide new features, where updates largely provide minor changes and fixes.

If you want those or other app updates, or if you want or need an app that requires a macOS version newer than High Sierra, then you will need to upgrade macOS—an upgrade to a new macOS version such as to High Sierra or Mojave, as differentiated from an incremental update to a later version of High Sierra, though you're probably already at the final version of High Sierra—if your Mac is supported by those newer macOS versions.

The recent iWork updates require Mojave. Other app updates can have different requirements.

How to upgrade to macOS High Sierra (10.13) - Apple Support (if you're not already on High Sierra)

To upgrade to a newer version, first check that your most important apps are supported on the new release and/or that app updates or alternatives are available—Office 2011, for instance, is long off support and has issues on newer releases and won’t work at all on Catalina, nor will any other 32-bit apps work on Catalina—then check that your printer and scanner vendors have drivers available—these drivers are provided by the device vendors, and are not created by Apple—and then get a backup or two—that backup is your sole path for backing out of a failed upgrade, or for downgrading should there be a problem encountered with your use of the upgrade—and then upgrade.

You need a later OS to get those updates.
