Sequel Pro requests access to Photos #3483
Steps To Reproduce
This happened to me once before, but I clicked Don't Allow and didn't think much of it at the time. Chewing on it later I wished I'd taken a screenshot and noted details of when that happened to assist in filing a ticket just like this.
This is something new with Mojave and has nothing to do with SequelPro (as far as I can see). Mojave introduced new privacy settings. For example, if you attempt to enter the photos directory from within Sequel Pro, you will get this prompt. You can safely click the "Don't Allow" button. If you clicked "OK" already, you can go to System Preferences >> Security and Privacy >> Privacy, and under Photos, uncheck Sequel Pro.
