Is the build # the same as the GM?
Developer program users:
Move to the trash the existing Lion installer you have in your Applications folder (i.e. the GM version downloaded earlier in July).
Close and reopen the App Store and the INSTALL button on the Lion page will become visible. Click it and you'll download the latest version. No need to pay anything.
That's what I'm doing.
I can confirm from that this is the GM build. Im inside an apple store and checked the Build number.
When trying to buy it says i have a newer version!!!
Whats up with the scrolling? Up is down and down is up? No more 3-finger back-forward scroll in safari? Er..what.
Get the free upgrade here if you got your Mac on June 6th or later.
