I have a house full of Mac's. 2 iMacs, my trusty Powerbook G4, and my Mac Pro. They are all running 10.4.10, except the Mac Pro. This is because when I first installed it, it would hard freeze. Not reboot, not Kernal Panic, but freeze to a dead stop. When running 10.4.9 it will run for weeks and weeks with no issue, infact its rock solid. So, when getting these hard freezes, i down graded (full format) to 10.4.9, and normality returned. Now with iLife '08, and iWork '08 being 10.4.10 dependent, i tried again. Freezes returned. So, i've archive installed, and im back and running stable with 10.4.9 again. Anyone any ideas what could be causing this, or should I just wait for 10.4.11/Leopard to arrive (which is already plan A).
