It would be really helpful if you explained what you mean by "link." For example, Macs can be linked to an iPhone in certain ways by sharing an Apple ID. They can't be linked by Bluetooth.

Can you explain what you're trying to accomplish?

Well yes, as long as none of them is stolen and is in your hand hahaha all models are compatible.

Ancient Macs may not be able to "link" (depending on what this means) to current iPhones, assuming there's no ownership issue.
