Hi, I just finished up getting this to run well on my Windows 8 machine, now on my Macbook with Lion 10.7.5, The initial scan says it's scanning, but the Files scanned: Threats: Processes all stay at 0 and the Time elapsed just continues to climb. Also in my dashboard it says 3 PC's protected but the Macbook does not show up there. In the My Account section, under status it says Waiting for license even though I have input the license key successfully. The only way to exit the program is to kill it out of activity monitor. Clicking on the icon in the system try to kill it does not work. There is no context menu choice to scan items either.
So it sounded like a broken install at that point, so removed it and tried to reinstall. That failed with the same behavior. Then I REINSTALLED LION and updated it to 10.7.5 and it still happens. I'm stumped.
