Command Line Tools beta 1 for Xcode 11.0 offered as an update in the current latest public release of macOS Mojave 10.14.5
Why is this beta release of CLI tools offered as an update?


This update is mistakenly released by Apple for everyone. This has happened last year as well when the betas for macOS Mojave and Xcode 10.0 were released for developers by Apple during WWDC 2018.

See the Q&amp;A from last year (2018):
