Pre Update Notes:
- This update may break some of your El Capitan functions, like audio and the nVidia Web drivers. So, being an Early Adopter maybe fraught with problems.
Make sure you backup first.
- If you're using nVidia drivers for your GeForce GTX 750, 750Ti, 960, 970, 980, 980 Ti and the Titans 'Maxwell' graphics cards, you'll need to install the nVidia 10.11.4 Web driver(s) after the 10.11.4 update.
You are advised to wait for nVidia's update or use the nVidia Yosemite Beta Web drivers. tonymacx86 will publish the link to the nVidia Web Driver as soon as it's announced, usually within 2-3 days. See threads in the
Graphics forum section if you have one of these Maxwell graphics cards.
Here's the step by step way to update for those who aren't using the nVidia Maxwell graphics cards :
Backup your current installation using Carbon Copy Cloner or SuperDuper;
Download the Software Update or Combo Update and run it to update to 10.11.4 - the updater will reboot upon completion;
Upon rebooting into El Capitan, you can:
Check to see if your audio is working (If you enabled Realtek onboard audio using MultiBeast v8 or toleda's CloverALC110 script, your audio should be OK),
(Optional) Update to the latest version of Clover,
(Optional) Check to see if your TRIM setting has survived through the update - if not, use the "trimforce" Terminal command[SUP]
1[/SUP]; if you've used the "trimforce" command in 10.11.0, then it should "survive" the update, but check to make sure; and
Re-boot

Tip: Don't use the iMac15,1 and Mac Pro 4,1/5.1/6.1 System Definitions. These SysDefs have been found to cause problems. For Haswell builds, toleda recommends iMac 14,1 for HD4600 and iMac14,2 for graphics cards; MacPro6,1 is only appropriate for X99 systems. Additionally, Clover is pretty "smart" about choosing a default System Definition for your system.
