Update 3/11/15 - this is resolved by the new version, which was pushed out to the Apple App Store yesterday. If you have a Mac, please open your App Store and go to the Updates section to install this new version.
Mac users who upgrade to 10.10 (Yosemite) will not be able to log into the OneClickdigital Mac Media Manager. The update has caused glitches in the software. OneClickdigital is working on a patch.
Only the OneClick software for Macs on Yosemite is affected. Your account on any other device (smartphone, tablets, other computers not on Yosemite) will continue to work.
If the Mac with Yosemite is your only access to audiobooks, you may manually download
some audiobooks from the OneClick website in the meantime. Please choose the correct document:
