The git commands you're seeing there are probably Apple's thin wrappers that are mostly meant to provide instructions on installing XCode, but SIP is stopping you from modifying the /usr directory (ah, Apple's Infinite Wisdom). There are discussions about working around SIP in the Apple forums [2] and Homebrew has some hints as well [3]. > > [1] https://developer.apple.com/library/prerelease/mac/releasenotes/MacOSX/WhatsNewInOSX/Articles/MacOSX10_11.html > [2] https://forums.developer.apple.com/thread/3981 > [3] https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/El_Capitan_and_Homebrew.md#if-usrlocal-does-not-exist Thanks. That helped. I will summarize here what seemed to work for me (skipping the wailing, gnashing of teeth, Apple tech support, etc.): [step 1] download and install "git-2.5.3-intel-universal-mavericks.dmg" as normal, ending with "Install successful". Confirm that git is still not properly installed. Shut down or restart. [step 2] Boot into the Recovery partition by holding down +R while power on and boot.

[step 7] Utilities > Terminal [step 8] $ scrutil enable [step 9] Restart normally ... *** Git now seems to be installed. I'm still having trouble getting it to work properly with a private GitHub repository. However, RStudio recognizes git, and I've confirmed that /usr/bin includes a subdirectory git-system and NOT simply git. My problems now seem to be GitHub and RStudio issues. Thanks again for your help. I hope this summary might help others. Spencer Graves > HTH, > Stephen >
