Did a fresh install on an external drive - want to test before putting it on main drive. COMPUTER: Model Name: MacBook Pro Model Identifier: MacBookPro5,1 First run through ... Noticed that neither the external HHD, nor the internal HDD icon was on desktop. One or two shutdowns and reboots and still no HDD volumes on desktop. While in SAFARI I noticed when downloading images, some hesitation and " bounce " in the displayed image. CRASHED while in SAFARI trying to load a new page using FILE/NEW TAB Got the beacball and NOTHING worked. Could not FORCE QUIT Had to force shutdown with Power Button OK Rebooted ... HDD Volumes now show up on Desktop HOWEVER ..... Something about the CLOCK DISPLAY When I look at the clock I see .... 3 21:38 When I click on the clock the top line reads ...... 3, 2009 9 08 I have no idea what the number 3 represents. Gonna reboot and see what else changes .......... SL now refusing to boot from external ..... Choose external and boot starts ...... Get the Apple / Spinning Pinwheel Under the pinwheel is a progress bar ( looks like the bar you see with a firmware update ) Progress bar never gets past 50% Does this twice and SHUTS DOWN !!!!! Any ideas ???
