Upgrading to OS X 10.9 (Mavericks) NOT recommended due to broken CUDA support http://www.primegrid.com/forum_thread.php?id=5340#70479 > If you are currently running any BOINC CUDA projects (not just PrimeGrid) on an Nvidia GPU we recommend that you do NOT UPGRADE to OS X 10.9 (Mavericks) at this time. > According to the BOINC Wiki, the Nvidia CUDA driver is broken. After ugrading to OS X 10.9, you will likely be unable to run any BOINC CUDA tasks until Nvidia fixes the driver.
