Apple has released 10.11.3 update. Backup your important data before trying the update.
- To update your existing El Capitan installation to 10.11.3, use App Store to try the update rather than the full 1.47 GB dmg updater. This way, your computer will have more chance to survive after the update :)
>> Good news, iATKOS EC installations on Skylake computers can apply the update (by using App Store as mentioned above).
>> If you used "USB Port Patch A" package during installation, then you may lose some of your USB ports after update. Try re-installing iATKOS EC with "USB Port Patch B" package and then apply the update after installation.
>> Some computers which can not operate without "USB Port Patch A" should not apply the update. We will release 10.11.3 revision of iATKOS EC soon.
>> After updating, do not forget to delete AppleHDA.kext that came with the update.
>> After updating, as usual, NVIDIA Web Driver users will need to update it too.
