Like many above my Mac suffered from the various forms of sleeping sickness reported.
My research shows that Apple are well equipped to deal with such issues and despite an obvious upsurge in business, the hoards abandoning the MS XP and Vista, they would soon be on the case.
However I did not expect the following and so record here points which may prove useful to others.
I was very pleased to see positive action taking place in the form of updates, one very small injection served to regain sleep normality although only briefly, and finally the Firmware Upgrade to MP31.006C.B05.
The first attempt at installing the latter failed miserably even though there was an appearance of the usual ‘Installation Successful with white Tick in Green Circle at what should have been the conclusion of the process.
There was nil change to the Sleep situation so checks were made to ascertain what had happened.
Via Apple > About this Mac > More Info > System profiler > Hardware > Boot ROM Version: it was obvious that the Mac was still on B02.
A while later I again hit the +Mac Pro EFI Firmware Update.app+ and followed the directions once again.
This time further instructions appeared, which had
not previously displayed, these required the user to follow a sequence involving Shutting Down the Mac and on Restarting to hold the Power Button in until specified occurrences.
This time the System Profiler confirmed that the Firmware Upgrade had taken place.
Imagine my feelings when this had absolutely no effect at on the Sleep, or should that be ‘lack of’ Sleep, situation.
Revisiting the Mac Help > Sleep > +If your mac won’t go to Sleep+, I checked all the possible causes which had been carried out several times previously.
The directives are not crystal clear, simply removing Check-marks reduces usability of the Mac. It took a little trial and error testing to arrive at what would work. i.e. permit Sleep, allow Sharing and Waking on Ethernet
*.
My set up is now as follows:
System Preferences > Energy Saver > Sleep > Default Options [Computer = 10 mins; Display = 10 mins.]
System Preferences > Energy Saver > Options > All except Restart after Power Failure are Check-marked.
System Preferences > Sharing > File, Printer and Web Sharing are Check-marked.
*It was Recheck-marking this facility that regained the Sleep function in conjunction with the other settings.
Although not verified at the present Default Energy Saver settings, at two minutes for both settings, the Computer Sleep takes effect two minutes
after the Display Sleep setting has taken effect. The Display sleeping after two minutes and the Computer after four minutes.
I would like to know if this is particular to my Mac or just a glitch?
IMHO it is reasonable to expect the actions to occur after the respective set times have elapsed.
The latter is not a major issue but it and the above report indicate that the whole experience may not be straightforward for everyone.
