Camera App Missing!!

And I believe my Photos library isn’t recognized due to my camera not being recognized. Regardless, the camera is the issue.

They are two separate issues. Photos will work fine even without the camera.

See here for help with the camera:

If nothing there works, I suggest you contact Apple and have them run a diagnostic. They can generally do that remotely.

There is no (and to the best of my knowledge never has been a) "Camera" app on the Mac. Photobooth is about the closest.

Hopefully, someone with more knowledge about your specific problem will be able to help with your issue.

There is no "camera tool". You can take pictures with PhotoBooth. Or, you can download other applications from the App store.

The Photos application is where you store your photos. It has little to do with the camera hardware on your computer. The library to which the error message is referring is your collection of photos.

The only camera apps I've ever seen on any of our Macs were those supplied by the camera maker. After a period of time we uninstalled all of those and use the native Mac utilities that allow access to the picture files on the camera. A couple of cameras my wife has will export the pics via WiFi directly to her Macs, but that capability is a camera feature that works in conjunction with her Mac's systems.

Macs already have everything we needed access the camera for offloading. Photoshop Elements my wife did want so we have that along with GIMP.
