Apple Seeds Second Beta of macOS High Sierra 10.13.3 to Developers

Apple today seeded the second beta of an upcoming macOS High Sierra 10.13.3 update to developers, one week after seeding the first beta and almost two weeks after releasing macOS High Sierra 10.13.2, the second major update to the macOS High Sierra operating system.

The macOS High Sierra 10.13.3 beta can be downloaded from the Apple Developer Center or through the Software Update mechanism in the Mac App Store with the proper profile installed.

macoshighsierra10133beta
It's not yet clear what improvements the third update to macOS High Sierra will bring, but it's likely to include bug fixes and performance improvements for issues that weren't addressed in macOS High Sierra 10.13.2.

No major outward-facing changes were discovered in the first beta of macOS High Sierra 10.13.3, but we'll update this post should new features be found in the second beta.

The previous macOS High Sierra 10.13.2 update focused solely on security fixes and performance improvements, with no new features introduced.

I could be wrong, but I recall the dark mode being more gray and translucent in prior versions.
It seems you have "Reduce transparency" on.

Bring AFPS support for external booting disks and Time Machine disks.
I’m booting an external APFS formatted SSD (in an usb 3.0 enclosure) on my mac mini 2012?

There IS a delay when booting from it (black screen for a little while) but it work.

On what machine is it not working for you?

Edit: Forgot to mention; this is on 10.3.2, not the beta.

Mine is, as well as iTunes when I sync and backup devices.

You ask this as if EVERYONE has this problem. It doesn’t happen on either of my Macs. Why don’t you call AppleCare?
