"The OS X Mavericks 10.9.4 Update is recommended for all Mavericks users. It improves the stability, compatibility, and security of your Mac. This update:

• Fixes an issue that prevented some Macs from automatically connecting to known Wi-Fi networks
• Fixes issue causing the background or Apple logo to appear incorrectly on startup
• Improves the reliability of waking from sleep
• Includes Safari 7.0.5

See below for Apple docs on Security fixes in OS X v10.9.4, Safari 7.0.5 and more. Build after update is 13E28.

OS X 10.9.4 Delta & Combo Update Download pages:
• OS X Mavericks 10.9.4 Update (delta) (283 MB)
• OS X Mavericks 10.9.4 Update (Combo) (958.2 MB)

FYI: Updating to OS X 10.9.4 (via SU) disabled the SSD TRIM support mod I'd done in OS X 10.9.3. (See earlier notes. Terminal commands I used before didn't work in OS X 10.9.4. Article now updated with TRIM mod commands for OS X 10.9.4.) WiFi internet connection was not working on the first reboot but OK after shutdown/restart. (Update process on a 2012 mini took about 10 minutes for 2 stage update.)

Saw some mixed early reports on fixes for multiple display problems (especially 3 or more) some Mac Pro owners had with OS X 10.9.3. Hopefully most are fixed.
