[Cb Protection] Important Notice Related to Latest MacOS 10.11 and 10.12 Betas
We are aware that Apple has begun releasing betas for MacOS 10.11 (El Capitan) and 10.12 (Sierra) that is believed to be related to the Meltdown/Spectre changes. We have learned from our customers, and have confirmed via internal testing, that previous Mac agents (including the recent 7.2.3-Patch 8 release) are not compatible with these 10.11 and 10.12 macOS betas and as such you will experience a kernel panic on boot.
In order to make affected machines usable again, you will need to boot into Safe Mode on each affected machine, remove any Cb Protection kexts manually, and then restart.
Support for the 10.11 and 10.12 macOS changes will be provided in a follow up 7.2.3 patch release.
Please do not upgrade to the latest MacOS 10.11 and 10.12 betas on any system with Cb Protection installed until we can provide an agent that officially supports these latest changes. Please follow this post for updates and additional details.
