I am a strong advocate (as is Apple) that you should NEVER interrupt the
installation process once you have started to update your system.
I'm loathe to ever suggest a 'Force Shutdown' by holding the Power button
during an OS X installation!
Doing this is NOT recommended as it has a high likelihood of interrupting the
installation process and causing something to go wrong, such as "Data loss".
Only ever do this if you have made a thorough backup of your Mac and understand
that you may lose all data that is not backed up.
I've seen computer operating systems 'hosed' because of this. Which then
required a "clean install" of the operating system.
I suggest that people just 'Wait It Out', sometimes it can take several hours
as the installation completes (depending on your Mac's system). Being patient
almost always resolves it.
What you could have done to see what was going on behind the scenes was to, hit
Command+L to bring up the installation log. This shows exactly what's being
transferred or copied.
Any Virus Protection program such as McAfee AV has been known to cause a
Freeze/stall when installing an OS X update.
Again it is important to:
1. Make a full backup, ideally you should have a bootable clone of your system
that enables you to revert to the previous pre-update state.
2. Turn OFF sleep for both screen and hard disk.
Turn OFF Time Machine
3. Disconnect all peripherals except keyboard & mouse
4. Repair Permissions in Disk Utility
5. Verify the state of your hard disk using Disk Utility. If any faults are
reported, restart into Recovery Mode - go to Utilities > Disk Utility and
Repair your startup disk.
At least then you can be 'reasonably' certain that your system does not contain
any obvious faults that might cause an update/upgrade to fail.
Cheers,
Ronni
