I have the same problem when I try to install LW Pro. I started the installation as per LW's instruction and clicked on the OSX option, the download seemed ok but the installation sticks with the coloured wheel symbol. I too have too force quit. I am just wondering whether using an Intel based Mac is the problem and LW's programming hasn't caught up yet? I have come across this alot with other downloads where the program is clearly not yet compatible with the new Intel Mac. The basic LW worked beautifully, so I'm probably wrong; also I am almost completely computer illiterate, hence me using Mac for the last 10 yrs or so… things don’t often go wrong! Can anyone help? Many thanks….
