MacOS 10.13.5 beta 1 was about 24 hours behind iOS 11.4 beta 1. If anything the install went a bit more smoothly than usual so that is good. The only new thing so far is Messages in iCloud which means if a message is deleted on one device it is automatically deleted on all devices using the same Apple account. Hallelujah!

If we knew what it was we were doing, it wouldn't be called research, would it?
