I did this

??update.packages

and got this message

starting httpd help server ... done
2017-04-18 20:09:42.918 R[12625:113901] App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

Then I did 

?update.packages

and got a blank help page.

help.start()  takes me to the browser with the index page.
But searching for anything is very slow.
