When using OS X 10.9 (Mavericks), the model formulation dialog of PcGive/STAMP/G@RCH sometimes takes a long time to appear. We have now discovered that this is caused by a feature that is called App Nap.
The Activity Monitor shows under the energy tab whether an application is AppNappping. It can be seen that activating the dock wakes all applications from App Nap.
To make OxMetrics behave properly, it is best to switch off App Nap for OxModel and OxRun. The next version, 7.1, will do this automatically. In the mean time, users of OxMetrics version 7.0 (or 6.x) can avoid the problem by switching it off manually. This can be done in two ways:
Locate OxModel in /Applications/OxMetrics7/bin/OxModel, Ctrl+Click on it
to activate the context menu, select Get Info and click on Prevent App Nap:
To disable App Nap for OxModel:
defaults write com.oxmetrics.OxModel NSAppSleepDisabled -bool yes
To check the settings of App Nap for OxModel:
defaults read com.oxmetrics.OxModel NSAppSleepDisabled
To remove the App Nap settings for OxModel:
defaults delete com.oxmetrics.OxModel NSAppSleepDisabled
For OxRun use com.oxmetrics.OxRun.
