Everything went fine with the build, as usual but after installing everything, psql did nothing but give a 'bus error: 10'.

SIP is potentially a good idea, but until they get the policies it enforces worked out, it's about where SELinux was ten years ago: the first thing you do is turn it off, if you want to get any work done. Right now it's an absolute disaster for anyone doing software development work. Here's what I have bookmarked about turning it off: http://www.howtogeek.com/230424/how-to-disable-system-integrity-protection-on-a-mac-and-why-you-shouldnt/ If turning off SIP doesn't fix things, we'll need to look closer. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
