I recommend using Switch by telestream. It's way better than Quicktime
Also misspelled Locket haha
Should check out Lockey By Crumb. That video is pretty awesome and it's shot with a 360 camera.
How about you live in the real world where money is an issue for some people. The camera matters as much as your story does. You're going to be able to produce a better story if you buy a cheaper camera with actual video feature, than if you just upgraded your phone.
I'm pretty sure you needed SIP disabled on your Mac to be effected. Which a lot these places do because there's a lot of old VPNs that require to turn off SIP during installation and most people never turn it back on.
You know you can get a Panny G7 with waveforrm and other video features for less than half the cost of an iPhone. If you can't afford a camera because you keep upgrading your phone, your priorities are in the wrong place for a filmmaker.
