So that’s it for the era of the big X. Version 10.12 of the operating system that runs the Mac is here, and with it, a new/old name: macOS. Though the name has changed, macOS Sierra follows Apple’s Mac gameplan of recent years, adding features in sync with updates to iOS, and expansion of iCloud integration. There’s also an intriguing new integration with iOS hardware, a major update to Photos, and a whole lot more. I’ve spent the last couple of months using Sierra almost every day. The X is gone, but the beat goes on.
