0 Votes 6 Views Ive recently noticed that from one of my keynote presentations it creates a '.spin' log whenever i close the presentations without saving or view previous versions of the presentation with the 'Revert to' option. I believe this is due to two things: the spinning wheel showing up before it closes(as it is a large presentation and could take about 3-4 seconds to revert changes) and/or when i go to view previous versions of the presentation sometimes the spinning beachball could briefly appear. While looking in the Console app i saw the 'Keynote...Macbook-Air.spin' logs and under 'Data Source' it displayed 'Stackshots'. Ive tried researching on what a stackshot is but came up short. I am using MacOS 10.13.4 High Sierra.

What Are Stackshots For Machines


What exactly is a stackshot? What are '.spin' logs and are they correlated to the spinning beachball?
