are the Lightroom CC and Photoshop CC compatible with Apple hardware and soft ware or would I have to buy new versions for Apple?
The CC license you have is for up to two different computers, including different platforms, so you should be ok as long as you login to the same AdobeID on the new Mac.
Yes, new versions are required however they are included in your standing CC subscription and you do not need to purchase a new subscription. Simply install them and login to CC when required. I have the CC applications running on a Mac and on Windows as a cloned backup. You are entitled to use CC applications on two machines concurrently.
