This version of WordSmith Tools is designed for machines with:
•at least 4GB of RAM
•at least 500MB of hard disk space
•Windows™ 7 or later, or an emulator of one of these if using an Apple Mac or Unix system.
You will find it runs better on a faster machine, especially if there's plenty of RAM.
You can run WordSmith from a memory stick on a fast computer better than on a slow computer. (You can run WordSmith on a tiny 10" screen laptop but all applications on those are slow and there is not much screen for your results.)
There is no Apple Mac version but see https://lexically.net/wordsmith/mac_intel.htm for details on how to use WordSmith on a Mac.
