updated to Mavs with Tiamo routine and SSD as boot. has issues waking from longer sleep, say 30 mins plus. The screen wakes up and I see the desktop, but I get the spinning beachball. The only thing that works from that point is a 10 sec power button hold to shut down. it's the OEM pram batt. Might that be it? I also have heard, though not proven, that the OEM 512M RAM may coz the issue in slots A-1 and 2. So I removed completely to test. Still have 8G ram installed in the proper manner. Could I safely remove the hibernation routine with Terminal? pmset hibernatemode 0. or perhaps change it to a longer default, say a couple hours? I have Energy Saver/Computer Sleep set to 1hr and that hasn't helped the issue. I just set to 3 hrs to see if there is any change. I've tried pram and pmc reset. No change. I also ran AHT from the disc, for what it's worth, the long version. No issues.
