I don't think so... I reckon it is the same crappy update... as the issue still seems to be occurring for other users and I contacted Apple on Twitter today and they are still claiming it's a non-issue.Yep. Yours could (!) be a new version of the update.

I'm going to wait and see for another few days. I will update to Mojave also if I ever get my power cable from China to install my new Sapphire PULSE RX580 8GB graphics card... Waiting 6 weeks already and still no sign. Another one ordered on the way also... but no sign of that also.
Thanks for all the contributions and comments in relation to this topic. Good to know my experience is not isolated to my own machine.
