Shortly after the release of iOS 11 public beta 2, Mac users also received a second pre-release build of macOS High Sierra, available for public testing ahead of its arrival this fall.
Participation in Apple's public beta system is free after registering and agreeing to terms and conditions at the company's website. Participants can test out pre-release builds of macOS, iOS and tvOS, though watchOS is not a part of the program.
In the latest High Sierra beta, Apple enabled initial Time Machine support, and has added routines to AVKit for developers to allow users additional flexibility for content playback when multiple outputs are available. Additionally, some touch event processing modifications have been implemented, with enhanced timing for ignoring errant touches.
The second pre-release beta of macOS High Sierra arrives a few weeks after the first build was provided in late June.
Apple recommends that users install the software only on a secondary Mac, and make a backup of that device beforehand.
High Sierra is due to launch as a free update this fall. The software will support standards like Metal 2 and H.265/HEVC video, and transition to the Apple File System, already in use on iOS 10.3.x devices. Apple is also planning miscellaneous upgrades to apps like Photos, Mail, and Safari.
By spring 2018, High Sierra will also officially support external Thunderbolt 3 GPUs, enabling high-level graphics normally reserved for gaming PCs and workstations.

I see mail is working better with this Beta :)
I wish some things come back from Apple :)

Apple fixed the sleep (not turning LCD back on) bug at least for my 2011 MBP. Now I can actually do some testing without worrying about having to restart all the time.
BY FAR the WORST BUILD EVER
The first public beta build was workable, 10.13 Beta (17A306f) is plagued with bugs. If you are thinking about public beta testing - skip this version. I can't keep up with all the bug reporting.
Some issues I'm having is Fan running all the time (iMac 27-inch, Late 2012) 3.4 GHz Intel Core i7 32 GB 1600 MHz DDR3 NVIDIA GeForce GTX 680MX 2 GB)
Bubbles appear while completing forms on safari
Flickering Safar preferences
copy and paste not always working ctrl C
computer becomes unresponsive for seconds
Try it if you'd like, but I would recommend skipping this version.
Fixed the screen brightness (frozen at max) from the 1st public beta as well as the no backlight coming out of hibernation. So far none of the issues reported by Zomp.
