you can render it back to a CGImageRef with a
bitmap context, and that can be done in a separate thread as well. Then you
have a rendered bitmap ready to assign to your CALayer contents property.

You want the FSEvents API. I’m pretty sure you can specify the start time for
the events, and subdirectories are included. My app specifically discards
events before I start monitoring.

I would start with something like this:
CIImage *img = [CIImage emptyImage];
for
re writing 1 jpeg for
