There have been two recent updates to the operating system of Apple. We are now on version 13.6.1
This was a small update to fix.
A green tint on screen due to thermal management issues
Some system files not being deleted when the storage was low
Exposure notifications disabled for some users as it relates to apps that need it like the Covid -19 type.
I dont know the name of this plant?
To get updates which are set as automatic or to see which version you are on go to Settings/general/Software updates .
Here you will see the update version currently in use.
Updates are down overnight when you are plugged in to the mains. ( There is a fear that a disaster would happen if battery was flat during an update!)
This update refers to I pads and I phones.
