And the unexpected benefits of what seemed like a thing I’d never use.

So, previously: my gorgeous 27in iMac is away off with the faeries – i.e. being seen to by Apple – and while it’s gone, I’m working on my old and I had thought underpowered MacBook Pro. It’s not underpowered. For the most part it’s doing its job well, I am doing my job fine. It’s got a broken keyboard but I’ve plugged in my iMac’s one and that’s all tickety-boo fine.

What’s really changed is that I’ve started using the Mac’s Full Screen jobbie. In pretty much any software you use on a Mac, you can tap a button or press a key to make that app fill the screen – and hide everything else. I have never used it before. I don’t want 27 inches of white blazing out at me when I’m writing.

Plus, it’s a slightly clunky idea because of the way you get back from this full screen lark to regular larking. You mouse up a bit until the menu bar reappears, then you find the button. Somehow a bit ugly.

Yet with a much smaller screen, I tried using this in one app and I’ve liked it so much that I’m using it in every app. I find I can swap between these full screen applications like moving from Word to Safari without closing the full screen, moving to the other app and reopening the full screen. Just the usual Command-Tab takes me through full screens.

Not always very smoothly. I seem to end up paused, hovering over the desktop for a time while it all figures itself out. But usually, I’m in Safari now, I’m in Mail next, it’s a quick thing and not anywhere near as disruptive to concentration as I thought.

But here’s the thing. Concentration. What I didn’t appreciate was that full screen apps hide their menu bar and that means they hide the clock. Hiding the clock turns out to be excellent: I could focus on the thing I was doing and spend whatever time it took. Of course, I have to leave for a meeting in a while so I couldn’t ignore time altogether but for about 90 minutes, I could.

Time passed but I was entirely focused on the job and if I sometimes longed for a tea break, I didn’t once stop to think about whether I had enough time to carry on.

If you’re not on a Mac, thank you for reading this far, and go find a way to switch off that damn clock. It’ll help you.
