Ask HN: Long time Ubuntu user switching to Mac. Tips?

Long time Ubuntu (Linux) user. Using it since Ubuntu 10.04 days. My new employer is only willing to provide a 2018 MacBook Pro (f* that awful keyboard and the next to useless touchbar). What should I be ready for? I am going to use an external keyboard, mostly. Dual-boot with Linux is somewhat out of the picture because of company policies, perhaps. Not so sure about things so just looking for advice on things that I might get punched with.
