I had all of the similar problems that everyone else previously mentioned while trying to update my 2012 MacBook Pro. Spent a while researching and was able to fix mine by rebooting in recovery mode and running first aid on the hard drive I was attempting to install on. I also removed all usb drives the time it worked nfs if it had an impact. Choose System Preferences from the Apple menu, then click Software Update to check for updates. If any updates are available, click the Update Now button to install them. Or click 'More info' to see details about each update and select specific updates to install. Update Issues with the latest MacBook update to version 10.13.4. I have just got the MacBook Pro and tried to update my software to the latest macOS High Sierra version 10.13.4 and just couldn't. It first started when I tried to connect my Apple Watch with the Mac. I get a result saying 'Mac can not establish a communication with the watch'. Uninstalled all office 365 apps. Reinstalled all apps from website. Account is active and valid. Word and Excel updated correctly from auto updater. Outlook package appears to download but fails to verify and errors out. I have also updated the updater program itself to latest version. Thank you for any help.
