Two factor authentication on older Macs 10.6.8 Snow Leopard
Hi. I am not able, to login to iCloud-services or accounts via Two factor authentication on older Macs on 10.6.8 Snow Leopard.
The OS tells me to login and enter the code but there is no form to enter a code.
I have two other, much younger Macs on 10.12.6 and also iOS devices but I don't know how to get services like calendar running on the older ones (which are still running and working machines).
