Stuffit expander will work on zip files.  The only thing (so far) I couldnt use stuffit for was the apollo downloads because it requires a password,however if your MAC is new you probably have a newer stuffit so you'll be fine.
Also could open a "terminal"  window and use unzip.
Except for programs themselves, which are specific to computers,havnt found things that do not work on the mac.
Oh,and I think some phython things may have problems,havnt gotten to that yet.
(We are a purely MAC family - I think bringing in a PC would be grounds for divorce)

Having fun yet? Very addictive!

"I paint that which comes from the imagination or from dreams, or from an unconscious drive. I photograph the things that I do not wish to paint, the things which already have an existence."
