OSX Lion - missing csrutil command

i have IMac 5,1 with Lion 10.7.5 OSX and in terminal i'm trying to use the command csrutil. I checked everywhere but didn't find the way to have and use it. The reason is that i would like to disable ( i know i have to do in recovery mode) to install windows 7 32bit( 64bit seems not possible) Last week i upgrade the HD to SSD of 1TB and RAM from 2 to 4gb and i used CarbonCopyCloner to clone the OSX but i lost the Windows partition that i would like to have again. Thank you in advance

Solution 1:

There isn't a csrutil command in macOS 10.7.

System Integrity Protection (SIP) was introduced in macOS 10.11, and the csrutil command is for modifying SIP.
