Problem with Directory on Mac

[Musiq]

Hello, everyone. I am currently having an issue with dolphin and I looked for an answer to my question in several places and have yet to find one that solved my problem. I believe that I may have accidentally set the directory to which Dolphin looks for ISOs to an area on my computer that does not contain any. Whenever I open Dolphin, a loading wheel is displayed the entire time and I can not access any options. I have also uninstalled and re-downloaded the newest version of Dolphin twice, which didn't work. If anyone could give any insight on my problem it would be appreciated. It is also important to note that I am using a Mac. Thank you.
