In December 2016, I kicked off a migration to Linux (from OS X) as my primary laptop OS. I thought that these “along the way” posts would be sufficient to keep readers informed, but I’ve had a couple of requests in the last week about how the migration is going. Linux Distribution. LTS (“Xenial Xerus”).
