When you say "6 point" do you mean it's bigger than usual?
Is there a place to obtain SF Mono without an Apple Developer account if you don't happen to have a macOS installation handy?
By "6 point" I mean the character itself has 6 "arms", instead of the typical 5. For my taste, it makes the glyph feel more balanced.
There is this repo: https://github.com/hbin/top-programming-fonts . Unfortunately, I'm not familiar with the legality of obtaining Menlo without OS X/macOS. It is a variation on Bitstream Vera Sans, which is AFAIK Open Source, but I am completely ignorant when it comes to how licenses apply to fonts (as opposed to code).
As for SF Mono, that seems to be impossible to obtain even if* you have macOS and an Apple Developer account (only the UI fonts are available for download). I managed to dig them out of the Xcode application bundle and install them as system-wide fonts, but was greeted with a very scary warning stating that installing these fonts could destabilize my entire system (so far my OS is still running, though)...YMMV.
Unfortunately, I don't see myself switching away from Menlo to Go Mono for a silly and purely aesthetic reason: 5 point raised baseline * . Yes, yes...I know that's how pretty much every font has done * since forever, but after working with the vertically centered, six-pointed * in Menlo (and SF Mono), it's hard to go back.
