Hey there!
I'm newer to the forums, I requested access in order to post about this topic specifically.
To start off, I'd like to mention I am currently running ESO on a Mac mini with the M4 chip at time of writing. That being said, I have had no problems whatsoever relating to the game itself — this is the only major issue I've run into so far, and even then I've come up with a workaround (as tedious as it may be).
I have been trying repeatedly for hours to get the ESO-Database.com Client app to run on its own without needing to use the aforementioned workaround, to no avail. The only way I can actually get the app to open and run is by right-clicking on it within my applications folder, selecting "open package contents" from the dropdown menu, navigating to the JAVA file, then running it by opening that. It runs and works just fine through that method.
Every other time I try to open the app just from the icon itself, I get a Finder permissions error, saying "Finder doesn't have permission to open (null)."
Does anyone know a possible way to get it to run without the need of opening the .jar file every time, and is anyone else having the same issue? Anything will be of help right now, I swear I feel like I've looked everywhere for a proper solution.
