It still isn't perfect but I guess I didn't pay for the app so I can be patient. With Mavericks I'm now able to extend the RDP session to multiple monitors with versionĥ with one caveat, in Mission Control Preferences the 'Displays have separate Spaces' MUST be checked (at least from the testing I've done). The main purpose of this app was to enable desktop users to remotely access their computer securely and easily from anywhere. I originally reverted back to Mountain Lion when the multiple displays didn't work, and Time Machine made this very easy. Google released Chrome Remote Desktop beta, a Google Chrome app, in late 2011. I'm pretty sure with Mavericks you'll be able to have your RDP session open in full screen on one monitor and simultaneously use your OSX apps on the other Have you considered upgrading to Mavericks? If you do, make sure to have a full Time Machine backup. Thankfully I still have the old version and can use that. Is no combination of toggles to not make it use the full screen with extended space mode. Before I could run full screen in one monitor while still accessing my other apps. I just downloaded the update, and it has become completely useless to me. I have OS X 10.8.5 running two Apple Thunderbolt displays.
