Understood.. lets try a couple of step then.
Open your finder ( magnifying glass ) type in disk utility, and launch the disk utility application.
On the left side of the disk utility window, click your mac hd, then at the lower right hand side, click repair permissions .
Once thats complete, lets go to your applications folder, find the google chrome application and trash it.
Then lets find the leapfrog connect application and trash it too.
Then, lets use safari, and then download the newest version of google chrome.
Once downloaded and installed, lets restart your mac.
And then using chrome, lets download and install the newest version of flash from this link
Once installed, lets make sure to restart the mac once more, and then lets download and install the leapfrog connect using chrome from here.http://www.leapfrog.com/en/pages/support/product_pages/leapfrog_connect.html
Once installed, lets run Leapfrog connect..
lets make sure it can see your leapfrog device first, then try to download something.. Will it let you download now?
