Thanks for the response.
I'm not sure what you mean by 'current lifespan of your version'. Do you mean the MacOS? It's up to date (10.15.7)

I suppose I could run other Mac diagnostics, but I'm not sure what more info this would give me. It's pretty obvious that Biab is an outlier application on my Mac in terms of resource consumption.

I've heard that some multi-platform applications (like Biab that runs on Windows and Mac), that are built from the same code sometimes can't always implement specific elements of the platform. For example, I don't think Biab on a Mac listens to the 'go to sleep' command from the OS.
