I have also seen this on several prior versions of the Mac OS as well.  I am 
invoking Lilypond via Frescobaldi, so I don’t know if there is something with 
how the OS handles those requests or if the OS is just slow to launch Lilypond 
(I haven’t tested it from the command line in Terminal).  Once it’s been 
launched once, subsequent invocations are immediate.  I do not recall if this 
only happened after a reboot, my sense is that I see it somewhat randomly even 
without a reboot.

I don’t know if there would be anything helpful in any of the logs that might 
be explanatory.
