Have a 2017 iMAC with the latest OS system- successfully transferred all data to my new iMAC. Now want to wipe clean the old MAC so I can donate it.
Followed all the directions on how to accomplish that task however the old MAC is telling me it doe not support the Transfer or Reset function. Now what?
Thanks in advance

Startup the iMac in Internet Recovery, as per > How to start up from macOS Recovery - Apple Support
If you are referring to Erase All Content and Settings, that requires a Mac with a T2 security chip, or a Mac with an Apple Silicon processor.
On those Macs, the T2 chip or Apple Silicon chip encrypts and decrypts the contents of the internal SSD in real time. The computer can "erase" the SSD by making the T2 chip or Apple Silicon chip forget current encryption & decryption keys in favor of new ones – effectively making all of the existing data so much unreadable hash.
The 2017 iMac does not have either type of chip, and does not encrypt and decrypt the contents of its disk in real time. So doing that type of "erase" isn't possible.
Easy, you re-connect it to the Internet!

Yes well, I assume the OP can read.
Which makes me wonder, why the post was moved from the iMac section to the Sequoia section...?
My guess is because Sequoia is in the OP's signature.
FWIW, there are only seven steps. :)

Great info many thanks But now with the MAC no longer connected to the net, how do I wipe the hard drive clean?
Why won't my old iMac support the transfer/reset function?
