macOS Catalina 10.15.5 won't update on my 13" MacBook Air 2015

I have a 13" MacBook Air 2015 and I am unable to update to the newest version of macOS Catalina (10.15.5).

When I press 'update now' in the settings under the software update tab. The screen goes black with the apple sign and a progress bar underneath. Once the progress bar goes fully to the other side (which only takes about 10 seconds), the screen goes black again and then comes to the login page where I have to put my password to my Mac in (as that is what I normally do to access my Mac). Which, when I go into the settings again, it still comes up with with the new update saying update now.

I've tried shutting fully down and turning back on again, which doesn't work and tried restarting, which also doesn't work.

Any help would very much be appreciated!

Boot into Safe Mode (How to use safe mode on your Mac - Apple Support) by booting with the Shift key held down and try to download and install the macOS Catalina 10.15.5 Combo Update from there.

NOTE: Safe Mode boot can take up to 10 minutes as it's doing some system cache cleaning, volume verifying and directory repairing.

There isn't a public version of 10.15.5, only a beta version. We're not allowed to discuss beta software in these public forums. You'll have to get help in the Appleseed discussions area.

Yes, I tried that already, does exactly the same thing in both Safe and Normal mode, it doesn't seem to make any difference.

Same issue for me as well. I can't get it to update. Apple, you care to chime in?

Hello - I have the same issue as well for my MacBook Air 2012 version and I have plenty of flash storage. Does anybody know how can we update? Thanks

Thank you Mr Philips! Downloading it now. Will let you know if it works. Do you know by any chance how long MacBook Air 2012 will be supported? Could this be the last update for us? Thanks a lot.
