These two things were shared with me by community fellows:
The "Continue" * panel
and
this link to the SRS software update option
About Rapid Security Responses for iOS, iPadOS, and macOS - Apple Support
I have just marked these as helpful.
I thought they both supported the idea that
The newly added SRS software update option was MANDATORY
(not an option at all).
I have never seen the "Continue" * panel
nothing more to be done there
but anyone can access the apple support pages.
I saw that the archive has 85 snapshots of those pages
beginning in December 2023 up to present.
I thought maybe these pages had changed since the beginning
and sought to see what and when.
I was surprised to see they had not changed at all.
So I decided to look at it more closely.
I was surprised to find that it described the
SRS software update option was TOTALLY OPTIONAL.
I now plan to inform the apple webmaster that these pages
are likely incorrect and ask him to please update them
so apple users are not misinformed.
Will keep you posted.
