I am brand new to FAH. Downloaded the latest release, 4.7.7., and am running on OSX 10.10 on a 15" MBP. In the viewer, the protein keeps showing only sporadically, or not at all. Is there a setting I need to change?
Saw your post over in FF ... Welcome to the world of folding.
Do you have some more details ... Could you post the folding log file showing what system and configuration you run ? And what project you got assigned ?
You might have too much CPU allocated to the folding and run short of CPU power to drive the rendering; even with GPU. You could also try to change the rendering details as mention in FF.
Since Yosemite is still beta I have it only on a MBA where I don't bother with folding. So can't really test your setup. But I will try the viewer and see if I can reproduce.
And as you are brand new to folding: make sure to get a passkey installed as early as possible to receive so called "Quick Return Bonus" or "QRB". It require to finish 10 work units successfully and will then increase your points quite a bit. http://folding.stanford.edu/home/faq/faq-passkey/
Please see over in FF: one member there found a bug ticket indicating that in some cases (projects) only every other snapshot is displayed. That could be your issue, too. That means nothing wrong with your setup.
Did you got meanwhile another project/WU assigned ? Same issue ?
