problem
I want to use EC2 to deploy an application using AWS.
After creating an instance on EC2, I downloaded pem, but I can't open it. I'm still not sure if it needs to be opened, but I get an error so I'd like to resolve it before proceeding.
You cannot change the "system root" keychain. It will be.
Even if I have the pem file in the keychain, it is not registered.

I moved it to the ssh folder and changed the permissions with sudo chmod 600 ~/.ssh/○○ .pem!
Then I was able to log in to the instance. I think there is no problem, so I will solve it.
