my guy, i'm also using MAC on the stoned sierra and it's seriously a pain in the ass.. either you get the "file is damaged" please delete window and can't open the file, or i've gotten the terminal window where it says my session was closed and saved and doesn't start the mining process back up even though the miner is plugged in. you just have to mess with it. from copying the folder then changing the "run moonlander 2" then saving then copy. or even changing the "run moonlander 2" file then copy and save. It sucks..but after a few strained hairs and some cursing it worked again..BUT before that..dont forget to turn your mac off, and do the PITA process where you disable the SIP and then install the slialabs driver then turn the mac off..restart..again..and re enable the SIP. then you should be able to download the MAC64(new updated version) BFGminer ZIP..if im stating that correctly. then after that it's back to messing around with the copying and getting the ML2 to run with your user and preferred clock speed settings.

In response to JAUER...yes i also had this issue where I STILL had to babysit the miner to make sure it ran correctly and didn't either just randomly shut off/stop hashing/ or a new one i recently encountered was it said the "pool was dead" so idk..just kinda still messing with it on my MAC to see if i can get this sun of a beotch to run correctly..
