Troubleshooting OS X 10.11.4 Installations & Updates
Some Mac users have reported a variety of issues with installing OS X 10.11.4 on their Mac. The problems may vary from a frozen or stalled installation, to unexpected crashing during the update, and a variety of other issues. Some users may encounter a kernel panic on boot or during the update as well.
Users may be able to remedy a failed update process by rebooting the Mac into Safe Mode (hold down shift key during boot), and then downloading and running through the update again using the Combo Update for OS X 10.11.4. This can often resolve installation errors and update failures.
One common reason for some Macs to kernel panic during the system update is due to a third party kernel extension called SUIDGuard, which hasn’t been updated to support OS X 10.11.4 yet. If you have installed the SUIDGuard installation, you would need to remove it before being able to complete the update by rebooting the Mac into Safe Mode with the Shift key, then open “/Library/Extensions” and look for “SUIDGuardNG.kext” and delete it.
If the update is successful but the Mac is running slower after updating to OS X 10.11.4, simply waiting for the various Spotlight and maintenance processes to complete usually remedies the speed issue and any potential rapid battery drain. This can take an hour or more depending on the speed of the Mac and the amount of data it accesses on a drive, so patience can be important.
In some cases, the only solution is to restore back to the prior OS X release with Time Machine, perhaps while a few remaining bugs or quirks are worked out.
