Before Emacs 26.1 child processes were created using
fork on macOS.
That needlessly copied GUI resources, which is expensive. The result
was that forking took about 30 times as long on Darwin than on Linux,
and because Magit starts many
git processes that made quite a
So make sure that you are using at least Emacs 26.1, in which case the
vfork will be used. (The creation of child processes still
takes about twice as long on Darwin compared to Linux.) See 2
for more information.
git installed from a package manager like

executable you’re running against the one at
/usr/bin/git, and if
you notice a notable difference try using the latter as
