My newish 15" MacBook Pro is having an issue installing 10.13.5 Developer Beta 2 from 10.13.4 Beta. The installation is attempted, but the installation process freezes when the black screen says "Restarting". It will stay on this for hours, and I ultimately have to do a hard restart. At this point, the update is not installed. This has been going on for weeks.
Thanks for any help!
