The memory and uptime won鈥檛 show up on iOS 12.1.1b3
6.0.1
Default
neofetch -vv 2> neofetchlogneofetchlog to pastebin, gist or Uuuh

I need a verbose log (see the instructions in your post).
Where is the log located I don鈥檛 find it
neofetch -vv 2> neofetchlog will write the log to neofetchlog. Upload the contents of that file.
and where is that neofetchlog because its not in the neofetch folder
...the folder where you execute neofetch?
e.g. [konimex@apple /tmp]$ neofetch -vv 2> neofetchlog will generate a log in /tmp.
Output of sysctl -n kern.boottime, sysctl -n hw.memsize and vm_stat?
@iandrewt Are you able to take a look at this? It's macOS territory :P
