Its already fine. Just like I said permission. Maybe because its encrypted? Hahahaha. That's what I only think the reason why for now. StarTrecker solution help me. I also see in reddit about cp -a for copying files through terminal as how it is "if" you don't have permission.
Also, the original poster who have problem here wants a full mac theme. I found one, https://www.xfce-look.org/ . It's not only for xfce. There's variety in that site so. I just try. Not a big deal to me. Learn a lot just by searching in this theme thing. hahaahha


I see the conversation continued and Jeslin covered this.
