The MacBook Pro still has a quirk that has always bothered me. It’s not a hardware issue, it’s a software issue. Power users with laptops know about “closed clamshell” or “closed display” mode. That’s when you use a laptop with a desktop keyboard and mouse and the laptop remains closed. I don’t think any OS I’ve used totally gets this totally right, they all have their quirks. The MacBook Pro just has this one quirk that gets to me.
The problem with the MacBook Pro is when you have the computer open and on and you connect another display you’re given the option to mirror or use the display as a second display. If you mirror and close the laptop it goes to sleep. That’s completely illogical. There seems to be no way to disable going to sleep in this situation that I can find. I can’t imagine why anyone would want another behavior when closing a laptop while having a display and input device connected. When no display is connected and the laptop is closed, it should obviously sleep.
Searching on Google returns numerous forum threads with people who also have this gripe. Even a check box in the Energy Saver pref panel to facilitate this would do nicely.
For the record Windows is no saint either. It’s handling of monitor resolutions, especially if your desktop display is a different resolution is abhorrent. It can result in anything from reshuffling icons to putting windows out of the display area. I’ve never even bothered with such functionality in Linux, at least not yet so I can’t speak to its competency in this area.
