I got a wireless keyboard with my 2009 24" iMac. I believe it's the same as the wireless keyboard available today. The keyboard held up pretty good except for the space bar, it has no springiness to it, no click feeling. It's very loose and sloppy. Surprisingly enough it actually works. But it's annoying to type on so I'd like to fix it. Is there any way to fix it or do I have to spend $70 on a new one?
