I am working on an app, built in Unity, and have built it to launch on Android and it works fine. I work on a PC.
I am now trying to convert the code to iOS. I have borrowed a friend's MacBook Air in order to meet the requirements needed for Apple. The first step requires me to make certificates.
I do not own this laptop. Does the certificate stay with the machine or is it just a file I can save into the cloud?
Also is the certificate required for updates in the future?
I ran into an issue previously where I created a certificate in Google Play and accidently deleted it, which forced me to make a whole new app. This made a whole bunch of other issues occur.
