Hello all! My sisters rev A macbook (Core Duo 1.83/1gb memory) is suffering with the common Leopard blue screen pause just before logging in. In this case there is however a difference. I've not performed an upgrade install, this is a fresh erase and install.. and i have no third party software installed. Symptoms are: The machine will boot up so far and then sit at a blue screen for several minutes (time varies) before displaying the login list. Sometimes while paused at the blue screen the white screen with apple sign will flash back up momentarily before proceeding. Thing is all current solutions seem to point to archive and installing leopard, but I can't see how that would make any difference - seeing as I've performed a fresh install. Tech Tool Pro 4 doesn't find any issues with the HDD or memory, and I haven't made any hardware changes. I've reset the PMU/PRAM also, and there are no external devices attached. I've installed more than once now with our Leopard retail disc (we got a 5 user for our family) and no change. Does anybody have any ideas of what to try next?
