I recently purchased a Macbook Pro to produce music. I installed Logic Pro X. However quickly after I realized I would need to uninstall it and reinstall it for performance reasons. I deleted/trashed the program and all the files I could find related to Logic. I have cleared the trash as well. But I know it is not as simple as that. Essentially Logic has been installed and uninstalled twice so far. How do I make sure that I still don't have unneccesary files/previous downloads. I want to make my Macbook as fast and clean as possible and I have a feeling I messed it up. Help? Am I better off returning it and just getting a new one and starting from scratch?
