Upgrade for 10.15 shuts down restarts but doesn't upgrade

I have done the last upgrade to 10.15.4 in the last 3 days my mac book notifies upgrade

available but when i proceed to upgrade now:


it only shuts down restarts and nothing else happened, any one experiancing the same

and what is going on. When attempting to deploy xCode new debug apps to

iPhone i get a notification xcode not compatible with this new Beta Release of this device.

I did an upgrade three days ago when receiving upgrade notification for iOS 13.4 latest beta.


On the download section for developer is says now OS beta version available.


Anny one any answer highly apprechiated
