anyone familiar with writing app_info.xml files whip me up one for OSX that limits 1 WU per gpu. i just added a second GPU to my machine (not the same as the first), and no packet will start, but if i switch over to Einstein@Home, then each card runs 1 packet just fine. i've read the windows users have this issue as well, and have found numerous app_info.xml files for windows, but nothing for mac. any helps oudl be much appreciated.
