Unlocked bootloader but cant root. (Mac) A few months ago I rooted my android phone which went all fine. I then accidently uninstalled my operating system. Finally I managed to flash omniROM on my device which  was as good as it got for me. The only problem is that I am not rooted anymore. My boot loader is unlocked but no root. When I run the usual commands on my computer (Mac) it just says access denied at the finish. Any help would be greatly appreciated. Thanks.

Also when I go on root checker on my phone it says. ACCESS DENIED. not rooted properly
You should be able to download the latest SuperSU from Chainfire and push it to your SD card and reboot into recovery mode -> install zip from SD -> select SuperSU.zip and it should install the SU binaries.  You should be good from there.
