If you like to shoot tethered (with your camera connected to the computer and the photos immediately being imported into Lightroom), and you’re a Mac user, you might want to know about this bug before you think of upgrading your operating system.

Kevin Tieskoetter (Lightroom Engineer) has posted an update on the issue:

We’ve found a solution to the tethering issue on 10.6.8 / 10.7 and the fix will be included in the next dot update. There were apparently changes in the USB drivers starting in 10.6.8, and, as best I can tell, the OS puts the connection to sleep after a certain period of inactivity. I’m not sure if they’re doing that to reduce power consumption or some other reason, but it caused LR to lose the connection with the camera.

I’ll post again as soon as 3.5 is available for download. (I know, I really must get back to posting more often!!!)
