Converting Captures to my computer

I'm trying to upload captures from my xbox one to a USB or straight to my mac, is this possible? How can I get the captures onto my mac?

Unless you run something that can stream the xbox app, you would have to use a capture card that can take a HDMI input, there isn't a streaming app for the mac that I am aware of, unless you decide to broadcast to mixer, and then capture your mixer stream.
In that case,m you may as well use mixer to capture the content.

Instead of going through the hassle of downloading files through a mobile app and emailing it, the most convenient method would be to plug in an USB device to your console, and have the console prepare it for capturing.

For existing clips, you can use Upload Studio on the console to upload your clip(s) to OneDrive, and then downloading them to your Mac through the OneDrive website.

Hello FutureSnipes22 and thank you for your question. I have found that if you download the mobile app on a external device you can save it to the device and email it to yourself. Carefull as if the file is too big it will not send correctly. You can also
use the windows 10 xbox app to access the files. At least that is what i did.

The most comfortable option is through ONEDRIVE: https://support.xbox.com/en-us/xbox-one/apps/onedrive.

I upload to OneDrive and then download them from there to my PC. As i dont have a capture card i find it the easiest to do it like this.
