Mac OS Update 10.14.6 (18G95) messed up my MacBook Air

Yesterday, I received a notification to apply an update on my MacBook Air (13-inch, Early 2014). I restarted my computer at the end of the day to finalize the update.

After the reboot, my MacBook Air was really messed up, I could not open any software, even Finder was failing. I could only open the system preferences but the Software Update also gave an error.

I had to re-install from recovery mode (Press Command (⌘) – R during restart) to be able to reinstall the update properly which took about an hour. I am now properly running 10.14.6 (18G95).

Has anyone else faced a similar issue? Any idea what would have caused that?

FWIW, in the future if you encounter such issues, before performing

a full re-install, when in Recovery, check "Restore from Time Machine".

Even if you don't have Time Machine enabled, any macOS update will

automatically create a local snapshot of your system before the install.

It will remain a day or two and can save the time of doing a full install.

The downside is is make sure you have saved any data before hand

that may have changed since it will take the system back to before

the update.

If it has been too long and the snapshot is gone, then re-install macOS.

Thanks woodmeister50, since I did my last time machine more than a month ago I did not think of using the "Restore from Time Machine" method and I was not aware that a local snapshot is automatically created.

However, using that option would have bring me back to the previous Mac OS version 18G87, right?

What ever state your machine was in before the update,

which would be the previous build.
