** Synthetic fonts on macOS
Synthetic bold looks thinner if the background is darker than the
foreground and font smoothing is turned on. In such cases, you can
turn off synthetic bold for particular fonts and use overstriking
instead by customizing the variable 'face-ignored-fonts'. For
instance, if the problem is with the Monaco font, you could put
something like the following in your init file:
(push "\\`-[^-]*-monaco-bold-" face-ignored-fonts)
