Just to clarify, in case you do want to upgrade at some point: Hauptwerk v7 is fully compatible with, and supported on, Macs running macOS 'High Sierra' (=macOS 10.13). It should work very well on an iMac running macOS 10.13.6.
(If you do upgrade to v7, make sure you follow the 'upgrading' instructions in the v7 user guide, since on a Mac you need to remove your v4 installation before installing any later Hauptwerk version, but you can keep your Hauptwerk settings, combinations, voicing, etc. in the process by using Hauptwerk's backup/restore mechanism, as covered in those instructions.)
Best regards, Martin.
