One week after Apple seeded the third beta of an upcoming macOS Mojave update to developers, Apple last night released a revised update for the software, fixing an issue where Feedback Assistant would unexpectedly quit for some users.
Apple appears to already have fixed the issue ahead of the second public beta release for macOS Mojave, which hit last Friday, and is now issuing the fix to developers newly downloading the update. Additionally, Apple is offering the revised version to developers who previously installed the original third beta version of macOS Mojave.
The Feedback Assistant app comes built-in with iOS and macOS beta programs, and allows public testers and developers to submit bugs and other problems with Apple's pre-release software in an effort to help ensure such issues don't affect public launches later in the year.
Apple announced macOS Mojave during WWDC this year, and the desktop software will see the introduction of a systemwide Dark Mode, Dynamic Desktops, Stacks, and a collection of ported iOS apps that will be available on Mac for the first time: Apple News, Stocks, Home, and Voice Memos.
