System taking up way too much space
Hi all,
Recently my Macbook Pro (Retina, 13-inch, late 2013) running on Mojave is taking up way too much space. Does anyone know how to fix this problem? See the screenshot, for some reaseon it takes up almost 90GB for "System" and "other volumes" however I have no f*cking clue what "other volumes" may be, since I can't find it back on my Mac anywhere.
Anyone that had the same problems, or could just help me? Thanks in advance.
Emiel
