i just did the supplementary update for 10.13.6. During the update my mbp rebooted quiete a few times and the overall update took about 30 mins. Its my first macbook and didn’t expect it to take this long. How long did the supplementary update take on your macbook?
I have a 13 inch 16/256 2018 mbp.
