Ever since early this summer, I have been experiencing periodic freezes and crashes in Logos/Verbum 7 (desktop) on macOS 10.12 and 10.13. It is more of an annoyance to me than anything else, for it does work as expected after the app relaunch. To help you understand what is happening, I put together this video: https://youtu.be/euP8ZfDWm-A. I hope you find it helpful.
I do have Xcode installed on both the MacBook and iMac, with all of the developer tools; if there is additional information you need for your troubleshooting, just let me know, and I will gladly provide it for you.
