Can I install the Charles Proxy certificate without a computer?

No, you cannot install the Charles Proxy certificate on your Apple TV 4K directly without using a computer. The process involves generating a certificate on your computer, importing it into Charles Proxy, and then accessing the certificate on your Apple TV 4K.

You’ll need to use a computer to run Charles Proxy and generate the necessary certificate. You’ll then need to transfer the certificate file to your Apple TV 4K. This can be done by either using AirDrop, sharing a network drive, or using a USB drive. Once the certificate is on your Apple TV 4K, you can follow the steps outlined in the guide to install it.

What if I can’t find the certificate file on my Apple TV 4K?
