My MacBook air with Mojave failed to install update 10.14.6 error code ERROR_7E7AEE96CA, what to do?

Hi endolap,

Welcome to Apple Support Communities. I understand you're unable to install macOS Mojave 10.14.6. I'll be happy to help.

If you're attempting to update the software on your Mac from System Preferences in the Apple menu, I suggest manually installing the update by visiting this link here: Download macOS Mojave 10.14.6 Combo Update This may help install the update.

Kind regards.

endolap,

Thanks for getting back to us and for providing that update. That's wonderful to hear. Have a great rest of your day.

Cheers!
