I am trying to Update the OS from macOS Catalina 10.15.3 to 10.15.4 on my Macbook Air 2014.

Every time I click on Update Now Button for updating the OS, a prompt appears saying

"To Update You must restart your Mac"

However upon restart, installation doesn't happen.

I have been trying to install but am ending up with restart multiple times. There is no progress with the OS upgrade.

Do you have at least 20GB - 25GB Free space available on your MacBook Air? If you do not then free up some space to address the update issue. If you have the free space and your MacBook Air is not updating then try installing the macOS Combo Update directly from here ➔ Download macOS Catalina Combo Update
