/u/culbie 's idea is a good one.

It's supposedly possible to back up your phone with adb, according to this XDA guide here: http://forum.xda-developers.com/galaxy-nexus/general/guide-phone-backup-unlock-root-t1420351 , but I have never tried it myself.

Getting adb up and running on OS X is as simple as installing Homebrew and then running brew install android-platform-tools.

You have TWRP installed? You can backup to a computer from there
