My spacemacs has a bug. When I’m using it, a window split occurs and Warnings opens with the following info:

Warning (emacs): recentf mode: Doing chmod: Operation not permitted, /Users/prikshetsharma/.emacs.d/.cache/recentf
Warning (emacs): recentf mode: Doing chmod: Operation not permitted, /Users/prikshetsharma/.emacs.d/.cache/recentf

Warning (emacs): recentf mode: Doing chmod: Operation not permitted, /Users/prikshetsharma/.emacs.d/.cache/recentf

Looks like something is awry with your permissions. Now I’m just guessing here, but try seeing what your permissions are for recentf and your emacs executable. You can find out using ls -l.
