I have two Macs. My reasoning behind this is I try to keep one for work and one for regular reinstallation. After all, when you review a huge number of apps, some of which worm their way into the operating system, you occasionally need to nuke from orbit. Because of this, I’ve only just upgraded my main work Mac to macOS Sierra, which I now use daily rather than specifically when writing about new Mac apps. And it turns out that either my installations of Sierra are broken, or Apple’s had a massive brain fart.

If you use a Mac, chances are you use Photos. It merrily sucks in all the stuff you shoot on iOS devices, providing a central repository for pics, videos and screen grabs. Lovely. Except that on macOS Sierra, you don’t appear to be able to drag and drop a photo on to a Dock icon, in order to open it in another app. That’s right: Apple has managed to fundamentally break one of the key aspects of the entire Mac experience. To which I ask: does anyone actually test these things? (Or is this another aspect of ‘courage’, like dropping the headphone jack?)
