If you, or indeed anyone, can shed some light on this, molto grazie

I have the exact same problem. Apple, fix this asap. I need my laptop to do work. I am now in safeboot and can barely function! BTW, mine is 10.8.2, and it's been off and on since 10.8, but now it's stuck completely.

http://reviews.cnet.com/8301-13727_7-57516188-263/macbook-efi-firmware-updates-f ollow-os-x-10.8.2-release/

Try this. I haven't had a chance because I just restore from my time machine to 10.8, I need my computer to work for now.

I am having the same problem and I think I have identified the problem area. Its when finder (even in the background) detects a .exe file. As soon as the file is detected, OSX freezes. Also, it is impossible to select a .exe file without OSX freezing. I did not have this problem with 10.8.0 and earlier versions

Since I uninstalled Kaspersky Internet Security the freezing problem is gone. At least on my machine, this was the problem

Just thought I'd add my 2 cents. I was getting lots of freezes and spinning beach balls in Safari, system preferences and Finder. I did a speed test of my ssd OS and it showed a really slow speed (in the tens of kb/s).

I had a cheapo USB stick attached which had contained some photos I'd erased (by disk utility format) and should have been empty. When I removed this the speed went up to 30-40Mb/s. After updating the firmware, I'm a bit over 100Mb/s.

Still getting the occasional freeze on safari, but I think that USB stick was the primary culprit in my case.
