I'm only a four day owner, but just installed 10.5.4 via the retail-disk direct method to a Runcore 64GB by following the directions in the guide here to a "T". I then upgraded via software update to 10.5.8 and this baby is running great! Everything works perfect, have been using a bluetooth mouse and making video calls on skype and YahooMessenger. The card reader and audio are fine too and at the moment it's even sleeping properly by simply closing the cover.....was surprised by that one! I did the exact same procedure on a friends Mini9 at the same time and he also has no problems. Used the DellEFI1.2a5
A HUGE thanks to everyone on this forum who have done all the dirty work and were willing to share the bounty..........Was just plain sick of waiting for Apple to WTFU!
