Nice, which project's?

TN on a Macbook

MikWay and Rosetta on iMac (that's faster, on iMac I have both 4 CPU and 1 AMD)

Anything to suggest for future?

And by the way is there GRC wallet for Mac, or there is no?
If no, may be it's possible to leave on Gridcoin Pool wallet from Bittrex?

Thanks in advance

Not an official one that i could find, a homebrew one i saw, thats something to bring up in the GRC community. But yeah pool mine GRC build up your amount and then if they make an OSX wallet youll have a decebt amount to go solo
