macOS Mojave beta 2 Release Notes

macOS Mojave

macOS Mojave beta 2 is pre-release software. Do not use this pre-release software in a commercial operating environment or with important data. You should back up all of your data before installing this software and regularly back up data while using the software.

Always back up your data and files before installing beta versions of macOS. If you have multiple Mac computers, we strongly recommend installing on a secondary system. Backing up files on a Mac is easy with Time Machine, the built-in backup utility.
