The only reports I've seen, on https://groups.google.com/forum/#!topic/sage-devel/OBv5x1v3_6M, have been positive. What conflicting reports have you received? I haven't tried it myself; I'm still running 10.9.
Here's a summary for how to disable it: 1. Reboot, holding down Cmd-R to start in Recovery Mode. 2. In a terminal window, execute csrutil disable 3. Reboot back into non-Recovery Mode. Here's a warning for why you might hesitate (this is my understanding of the issue; someone please correct me if I'm wrong): In OS X 10.11, Apple changed the operating system to no longer allow modification of certain system folders, even when logged in as root. They made this change to make it more difficult for malware to affect the operating system, but it has the side effect of disrupting Sage's current build process. Disabling system integrity protection may allow you to build Sage, but it also disables a security feature of your operating system.
