Turn on SIP on Mojave

I need to have sip turned on for TS on Mojave, SIP off is killing too much battery.

Please fix this.

We don’t have any way to fix it, see here: https://blog.binaryage.com/sip-and-mojave/ …although I don’t know of any reason that having SIP off would affect battery life (at least it’s not obvious that it would, but sometimes the internals of macOS are surprising).
