1 ) an iMac - he describes it as 2nd Gen Intel with 2GB RAM running i ~think ~ Snow Leopard
2 ) a MacBook also on Snow Leopard
He has downloaded Lightroom 4 and installed it on the MacBook and it's running well
He downloaded it on the iMac an got an error message telling him it wouldn't run on that.
Anyone got any ideas ?
