My Mac failed update to OSX 10.14.2
I just click to update to 10..14.2 in system preferences panel, and when downloading not finished, I disconnected network and reconnected with another network route(china local network, before that my route is through some US. West routing point), then I continued to download, when finished, my update failed, when click update again I continuously got 'Update failed / An error has occurred' message.
How do I get the update from start again?
