How to boot into recovery mode on mac without holding Command + R Key on keyboard ?

Generally well known method to boot the mac into recovery mode is by holding the Command + R on keyboard while mac is turned on. However you can force the mac to boot into recovery mode upon next reboot by changing the nvram setting. To do that, Run below command.  

sudo nvram "recovery-boot-mode=unused" sudo reboot


How to enable specific part of System Integrity Protection(SIP) while keeping few sections of it disabled.

macOS SIP supports a set of hidden options to disable few sections of SIP by passing hidden options to csrutil tool. 


 Each of these can be selectively disabled by running one of the following commands while booted into Recovery mode:
csrutil enable --no-internalcsrutil enable --without kextcsrutil enable --without fscsrutil enable --without debugcsrutil enable --without dtracecsrutil enable --without nvram
You can disable two or more components by structuring the command as follows: csrutil enable --without kext  --without debug

 Note : These options are tested on macOS ElCapitan , on higher version of macOS some or all of them may not work.
