os Mojave download

Look for the previously downloaded Mojave installer in your Applications folder, Install macOS Mojave.app, and delete it. Then boot into Safe Mode (Use Safe Mode to isolate issues with your Mac and Playing Safe: what does Safe Mode do?) and try downloading the installer again and install it from the Safe Mode.

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

Try using a new Administrator and create a Time Machine Backup (see below) prior to the installation. That way you have something to recover your Mac to, should anything go wrong with the update installation.

• Create a New Administrator User:

Create a new Administrator user and see what happens. If it does not occur, then it is something configured in your current user. Create this as the Administrator in:System Preferences > Users & Groups
