Computer went to sleep after the update. This was on Friday. Haven't been able to do any kind of thing on it. Trackpad 'clicks' but no screen, not touchbar, nothing (2018 Macbook Pro).
Called apple, they tld me it had to go a store, unfortunately where I live, due to quarantine there are no shops available to pick it, and we aren't allowed to drive outside our district.
Will try the apple configurator idea someone posted below and will report back. Just need to find a cable that supports both power and data that is USB a to USB c.
