Thanks! Just about to go to a early shift at work here in OZ Will try this this afternoon and get back to you. Thanks for your dedication!
I wish I could attach a beer or two to this post.
@macnb it's working fantastic. Boot's fast, sleeps fast, and recovers well from sleep and Siri and iMessage all a go. Power seems to be working very well it just idles along. Might be my imagination, but it appears that the UI is a lot more responsive, apps opening faster etc.
I noticed that in the System Information app, my graphics card is now saying: "
Metal: Supported, feature set macOS GPUFamily1 v3"... I guess this means that the GPU is now fully supporting the Apple Metal V3 (latest) driver?
I of course had to setup new serial numbers etc (or I did anyway because I wasn't sure if I could use my old ones with the new 13,2 spec.), but I had trouble with my WiFi/Bluetooth card, (Broadcom BCM94360CD 802.11ac), which caused me lots of headaches. I noticed that I didn't have Bluetooth, and even the DPCIManager app couldn't see it, I ignored it, and I was updating my iPhone 7+ when the network kept on disconnecting. Long story short was I had to do a factory re-install of the phone as it corrupted the install, (I had backed up prior to doing the update!). All's good now, I'm running on a older TP-LINK card ATM. I think the firmware is not right for Australian frequency spectrum.... to be continued...
Sorry this is of topic... I'll investigate it further and start a new thread...
I'm of to bed now as have a 5AM start, but do you want any further files eg IOReg, Config.plist etc.
Thanks again for all of your help, very much appreciated.
