Trusted Platform Module?

Mac's can connect to VPN network however I suspect the chip they're referring to is a PC only part and not necessary on a Mac. I would recommend contacting your IT department to get further clarification on their specifications.

I suspect that Robert and I share the same employer, and there is no flexibility at all on the requirement for the TPM chip. It is rather difficult to find any nice list on which models have it and which do not. So far, I haven't come across a page that just lists 'em. Oh well. Internal diagnostic says it's not installed. Which is sad, I guess.

I know for sure that some intel macs shipped with a TPM chip (my 1st gen second refresh macbook for e.g. couldn't find info on latest models. Try calling Apple

According to this article Apple stopped putting TPM devices in their computers back in 2006:

Even when Apple did have TPM devices in their computers there were no drivers included in the operating system to use them.

I enabled the Windows Bitlocker encryption function in the Windows 7 partition I have on my MacBook Pro and Windows did not see any TPM device in the computer. This is a MacBook Pro less than 6 months old.
