OS X 10.9/10.10 iCloud sign-in: Missing T&C tick box

OSX 10.9 and 10.10 install Guru

Introduction

Periodically over the last few months I have been attempting to upgrade my cloned OSX 10.6, 10.7, 10.9 and 10.10 to clean install them on a recently purchased and upgraded iMac 12.2 (2011 3.4 i7 with Samsung 2TB SATA SSD).

I want to create a time capsule of working CS5 with related working printers and scanners. The software sweet spot is Mavericks to Yosamite.

I have achieved fresh o/s installs of all four of the above, but icloud and Apple Mail remain inoperable due to software install glitches. OSX 10.9 and 10.10 are my prime concern in this respect. The problem I describe

below is identical for OSX 10.9 and OSX 10.10.

I would be grateful for assistance from anyone who can help me resolve the problem.

Method

After downloading fresh Apple o/s, I install on clean SSD partitioned under the name of each o/s. So I have four individual operational o/s (10.6, 10,7, 10.9, 10,10) on the SSD. Lets concentrate on 10.9 and 10.10 only.

After installation I begin sign-in sequence. I skip import data "from another Mac", I reach iCloud, sign in with my Apple ID and Password. On a second iMac 2019 I have simultaneously switched on, an address location

map asks me to approve sign-in from the iMac 12.2. I approve and a six figure number appears which I am expected to add to the iCloud Password on iMac 12.2. I add the six figure which are recognised by iCloud

according to both computers.

Next window is Terms and Conditions; Familiar to us all; I am expected to read, scroll down and tick a box acknowledging my approval before moving on. THERE IS NO BOX TO TICK. The continuation arrow at bottom right is greyed out awaiting activation from a box which no longer exists! This

happens identically on both 10.9 and 10.10.

My only alternative is to step back and skip icloud sign in hoping I can do the task later. Terms and Condition then re-appears with "Continue" arrow active. I click arrow and complete account installation and all looks good. But without iCloud there is no Mail. I open iCloud, provide ID and password which returns "not recognised".

On the 2019 iMac,

I open System Settings> click on my Account name, select "Password and Security", move to "Get a Verification Code", click on it and a six figure number appears which must be added to my iCloud password as previously described. "Password not recognised" is returned. I am now out of options.

Variables

10.10 installer downloaded from https://archive.org/details/install-os-x-yosemite.app 

File: Install OS X Yosamite 10.10.5_14F27.dmg

10.9 Installer from: curl mavericksforever.com/get.sh | sh 

Both files are from Apple official OS recovery servers.

On Mavericks, going to System Preferences>iCloud opens a window showinapps served by iCloud. All have ticked boxes except Keychain.  Tick the Keychain box and iCloud password is requested. When password is entered

the 2019 shows the location map and asks me to approve the activity with the six figure number.

However adding the six figure number to the passwords succeeds in switching Keychain on, but a small dialog box

advises confirmation "pending". Afte a time Keychain reverts to inactive. This behaviour indicates the passwords are being used correctly but an unidentified factor is causing password failure.

This problem is a nuisance, not a life or death issue. I would like to solve it if possible simply to have a clean operating system. I can use the 2019 iMac for emails but why use two macs when one is enough?

I need assistance from someone with an intimate knowledge of Apple installer packages, and interaction behaviours with OSX
