Ideally yes. It's your machine, loaded with whatever apps you've put on it, some of which may affect or be affected by whatever you do in the workshop. But looking again at your question, you mention both Mac and Laptop. If it is a big 27" mac I would be inclined to call the store and ask.
Great thank you, I have a old macbook pro and just got a new one, so decided the workshop would help and also find out how to load the new one with all my stuff from the old macbook pro. Am just using a passport to back up all my files off the old mac.
