Two Macs

I am going to travel to Europe for 3 weeks. I have an old Mac Air that I think I’m going to bring with me and turn off the MacBook that I’ve been using successfully with SpamSieve. Can I get SS working with the old computer? Thanks for help. The software is amazingly wonderful on my MacBook.

Yes, please see this page for how to transfer your training data to the new Mac after you install and set it up there.
