Okay, so I've figured out how to set up ADB on Mac OS X and I've followed all the instructions on how to get to Fastboot from ADB. The last command I use is:
fastboot oem unlock
This command in ADB is supposed to unlock the bootloader. On my device, it asked for confirmation to unlock the bootloader, volume up is yes and volume down is no. Well, the "no" option works perfectly fine but then the "yes" option does absolutely nothing on the device or the terminal window.
Does somebody know what's going on? I can seem to figure it out, even though I've searched all over the internet.
Some sites say that you have to take the device off of the charging cable before booting into fastboot, but I've tried this and found it unsuccessful.
My device is running Android Lollipop. All the developer settings are enabled like they're supposed to and ADB commands all work until the point where I get stuck.
EDIT: I'm attaching a screenshot of what my developer settings page looks like. I can't find the OEM setting anywhere.Image
