Update: It looks like this no longer works and was deemed a security issue and fixed.
Booting into Recovery mode can take a while since the UI has to load and a full disk check is done. There is a way to get into SIP faster: by going into single user mode in the recovery partition:
To disable SIP quickly, reboot the Mac. At the startup chime, press Command-s-r (a good way to remember this is that command-r is the recovery partition and command-s is single user mode). The Mac will boot into the recovery partition via the command line. Since the UI doesn’t have to load and a disk check is not done, it is very fast. You can then do the following things:
- Disable SIP
- Enable SIP
- Partially enable SIP, but allow changing the boot device (NVRAM)
csrutil enable –without nvram
- Set Firmware Password
- Set allowed netboot servers
csrutil netboot add address
