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

What bug are you referring to? How much free space do you have on your boot drive?

Since this is just a user to user forum we're here to try to solve problems not listen to rants.

You should remember judging an update by what you read here is like judging the health of a city by what you observe none of its hospital's emergency rooms.

I think it's a bug if an update does not know how much space it needs for an update and/or does not inform the user that it does not have enough space, and just keeps going around in circles, each time wasting the user's time.

If other users say that 1TB is enough I am not going to waste my time in deleting data I need on my drive.

And yes, I would actually judge the health of a city by a hospital's emergency room, especially in these times.

I currently have over 385 GB of Flash storage available. I downloaded this 10.15.5 combo update to try in place of the original update that was downloaded through system update. I shut down and booted into Safe Mode as suggested. I ran the Combo Updater 10.15.5 then in Safe Mode and received this message...

... I am still looking for ideas or suggestions to be able to update from 10.15.4 to 10.15.5

At attempt to install 10.15.5 from the App Store by clicking the "Get" button redirects me immediately to System Update in System Preferences. Since I have already tried to install from there multiple time with no success I abandoned that process. I then did a search for 'recovery' in Finder and no such match for 'Reinstall MacOS' exists on my system apparently. Any other guidance or help here would be greatly appreciated. Thx!

When I attempt to update in Safe Mode using the App Store and get the error... Is there a way to determine which error occurred with a code to identify and troubleshoot from? Not knowing what error occurred is of no help.

Actually 10.15.5 was released today.

I'm back. I was updating my Macs. I see a screen shot was posted.

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.

I deleted a bunch of stuff and I still can't get it to work.

Edited

I tried the combo update and that didn't work either.

Help!

As I mentioned in my post, I read the solution and tried it and the previously posted solution didn't work. Just read!
