I just switched to the newest Mac OS, Mojave, and although I’m not a techie, I want to encourage creatives to make the switch when they can, because it offers some good tools for evidence gathering.
First, the OS displays more metadata, and does so without having to get into Photoshop or the like. It’s all (well, lots) right there in the finder. This will be helpful in checking metadata in discovery-produced materials.
Sadly, some people will try to fake evidenceand the metadata can help prove it when that happens. It’s also a great way for you to prove up your ownership, creation dates, modifications, and copyright management information, too, especially if combined with the second goodie: video screenshots.
Shift-Command-5 enables you to record your screen while you, say, scroll down on the page of a website or click to get CMI info from a photograph. This is a great tool and one which will be really helpful in negotiating settlements. Imagine having an infringer claiming that the work never appeared on their site. Now, you can click to that site from somewhere else and do it while recording your screen so, boom, there it is!
I highly encourage anyone who is gathering evidence to use this video tool to make short videos showing the work in its infringing uses, live. Still screenshots are still needed (sorry, bad joke), of course, but the videos will be very persuasive.
 I had this happen a couple of years ago when a defendant asserted a doc had been made years before it actually had; I busted him with the metadata that showed the original doc was first created the night before it was produced. The case settled shortly after that.
