I want to know where the working tutorial for installing Catalina on an external drive is.
All the tutorial I managed to google up for some reason failed to mention the "missing a firmware partition" error.
I tried to install it using clover or raw official installer, under a GUID scheme. All got stuck at this "firmware partition" gag. I tried to use apple FS but to no avail.
Would someone please help me? This is driving me nuts. My MacBook is genuine, not HacBook.
