Background & Summary

In macOS 10.13.4 (High Sierra) Apple has decided to warn users who are running 32-bit software. This warning is an early notice that, at some point in the future, with some unspecified version of macOS, Apple may remove the ability for 32 bit software to work. Unfortunately, the warning message is not very clear, and so we have written this document to clarify what you, as either an author, or as an end user of iScreensaver, should do.
