For readers that sent reports on using Chameleon SSD Optimizer/OS X Trim Enabler, let me know if you have any problems w/10.8.4. (Updater may overwrite enabler changes/mods.) Ditto for anyone that sees any pros or cons with 10.8.4.

I updated a 2012 Mini w/Intel 520 SSD (no TRIM, no 3rd party addons) using the D/L 10.8.4 delta updater, although after restart a Software Update check still listed OS X 10.8.4 despite "about this mac" verifying 10.8.4 was installed. Selecting update in the SU window cleared it. Disk Utility Volume verify (and permissions) checks clean.
   But I have seen the repeating coreaudio console messages (automatic stack shots disabled/enabled - ref: apple forum thread) with every sound played, even a simple alert tone in the Finder. Here are examples of the messages ('nnn' used in example, as number varies):

coreaudiod[nnn] Disabled automatic stack shots because audio IO is active (at start)
coreaudiod[nnn] Enabled automatic stack shots because audio IO is inactive (at end)

And I have no 3rd party addons, no added audio plugins, system mods, etc. (I suspect this is common/normal behavior now but feel like someone left a debug mode enabled in the final release.)

Here's links to a few Apple forum early posts on OS X 10.8.4 update problems some have seen. (Often not common, but a FYI as some may include tips or later solutions.)

• OS X 10.8.4 External Display Problem (MacBook Pro 2008/09 models) (nvidia related?)
  (here's an apple doc on Troubleshooting issues with internal or external displays)
• Samsung (LN40B530 TV) HDMI 1080p no longer works after 10.8.4
• iMac fans running at full speed after 10.8.4 update (fixed by resetting SMC)
• OS X 10.8.4 unable to connect to exchange
• OS X 10.8.4 update failed (fix was uninstall Vodafone Mobile Broadband)

As always, don't forget to check for any updates to 3rd party addons/plugins/etc you may have installed. (Also old tips like disconnecting/reconnecting devices, reinstalling the OS update from a Download/Combo updater (link above), Recovery boot for volume repairs, (or reinstalls), test with a different acct login (as a check for problems with addons/prefs in the original acct), pram/nvram zap, smc reset, cache clearing, etc.) A current backup before updating of course is a must. (Having a known good/bootable clone of the boot volume is also well worth the cost imo.)
