As you know I have a Beta account with Apple for the macOS. I just installed 10.14.4 Beta 5. It would appear that 10.14.4 is pretty close to being released if they are on Beta 5 already. The install went fine, the update is great. The Beta 5 update is very snappy, my main Apps seem to run fine. I am looking forward to this update, it should be out in the few weeks I think.
