Solved: double click refuses to work
Saturday, 27 October 2012
For maybe 12 months I was frustrated because if I double-clicked an app, file or folder on my MacBook Air nothing happened. I expected the double-clicked item to open, but it never did. It was mystifying, confusing and annoying. Then finally I solved it. Here’s what was going on.
Double click should open things
I’ve used Mac laptops for at least a decade now. Before that I used desktop Macs. And in all that time, I was able to double-click on an app, a file or a folder to open it. It’s always worked, so it was a huge mystery and annoyance to me when it would never work on my MacBook Air.
After some initial troubleshooting I just lived with it. I would Control click an item and choose Open
from the contextual menu.
At first I thought it was something to do with Mountain Lion. But once I upgraded my main Mac to Mountain Lion and didn’t have the same problem on that Mac, I realised it was something about the MacBook Air itself.
Check the Trackpad settings
The first step was to check the Trackpad
settings in System Preferences
.

Trackpad settings in System Preferences.
Tracking Speed
actually controls how quickly the cursor shoots across the screen as you move your finger on a trackpad. That setting shouldn’t have made a difference, and in my testing it certainly didn’t affect the problem I was having.
I messed around with the other settings in that Preference Pane just in case, but nothing made a difference. I hadn’t expected it would.
I went back to work and decided to try again another day to solve the problem.
By the way: if it drives you crazy that the cursor moves s-l-o-w-l-y across the screen as you move your finger on the Trackpad, try changing the Tracking Speed. As the screenshot shows, I have mine set to as fast as it can go.
Check the Accessibility settings
The other day I was having another go at solving this annoying problem when I thought to look at the Accessibility settings
in System Preferences
. There, under Mouse & Trackpad
, was my answer: Double-click speed
.

Accessibility settings: Double-click speed.
At some point when the MacBook Air was new I must have gone in there, moved the slider to Fast
and then forgotten all about it.
Once I moved the slider back towards Slow
I was finally able to double-click on the Trackpad exactly as I expected.
My MacBook Air is so much more fun to use now. 😉

I have had this same problem forever. I never thought of checking the accessibility settings. Fixed instantly. Thank you.
The accessibility options in both OS X and iOS can lead to unexpected and frustrating symptoms for the unaware, but on the other hand they’re worth exploring for features that may make life a whole lot easier.
My primary example is “zoom”. In OS X this is usually done by holding down the control key while scrolling up/down with wheel/button/touchpad. In iOS it is usually done by a three finger double tap. Well worth knowing if your eyes aren’t quite what they used to be!
I was caught out myself by the 3 finger double tap recently. I had damp hands from cooking and was hurriedly trying to tap the Pause button on an audio file on my iPhone. It wasn’t responding so I tapped repeatedly. Next thing I knew the screen had zoomed and I couldn’t figure out how to unzoom or to scroll around to see the Pause or other buttons.
I think I just muted the phone until I had a chance later to consult the Settings app.
At least I knew enough to check Settings, but it was surprising and alarming. If, like many people, I hadn’t known that Accessibility settings even existed I could have ended up talking to tech support.
