Dear friends!!

I hope all is great on your corner!! I ask for urgent help about Maxcoin Mining.

I have been mining Bitcoins + Doge for a long time and Im now mining Maxcoins. So far in my "mining career" I have never experienced this problem, however I get this frutrating situation when trying to mine Maxcoins.

After 30 mins 1 hr of mining, the miner crash and It gives me two types of errors :::

Segmentation fault: 11 (most of the times)

Or

Abort signal 6 (sometimes)

My system ::
Apple Imac Mid 2011
Memory  4 GB 1333 MHz DDR3
Graphics  AMD Radeon HD 6970M 1024 MB
Software  OS X 10.9.1 (13B42)
Cgminer 3.6.6 -- arranged for accept sha-3 and released with the maxcoin lauch --

Any hints?

Thanks a lot for your help!
