I noticed that there was an update for Olympus 45 mm f/1.8. Tried Olympus's updater 1.06 and it isn't working on OS X Mavericks. Gives me an error about connection to camera after I agree to the terms as I click update. "Failed to communicate with the camera. (0x42000)" Anyone with similar issues? Not a rush for me as the update is minor and is for support on new Panasonic bodies. PS: I've always used the Olympus app with success in the past, this is my first time updating in the new OS so I assume that it's the culprit. Update: I was able to update without any problems a few days later. Perhaps Olympus servers were down and that's the error message you get...?
