If you’ve purchased an upgrade to Logos 4 to take advantage of the big discounts on all the new books, you can now access much of your new content using Logos for Mac 1.2.2. Please note that some resources are designed specifically for Logos 4 and will not work in Logos for Mac 1.2.2. Resources that do not work in Logos for Mac 1.2.2 include media resources, reverse interlinears, and some other resources.
How does one get the earlier version to find the Logos 4 books?
