Apple does not usually take their macOS Beta’s to a version 7. MacOS High Sierra 10.13.4 Beta 7 was released yesterday. Of course I installed it on my Beta drive. There were no issues whatsoever. It still remains very snappy, very responsive. All my main workflow Apps work fine. I can’t believe Apple is going to go much longer without a final release of 10.13.4, just have to wait and see. I am really looking forward to having all my Messages texts synced through iCloud, a new feature coming in 10.13.4.
