This is a Mac OS X 10.9 and later issue only. <\/p>\n
Among the number of power-saving features that Mac OS X 10.9 introduced, the App Nap feature overrides an application’s request to use the CPU and ports. If the feature engages during certain data collections using Logger Pro<\/i> and an interface such as LabQuest, connection to the interface can be lost, ending data collection. <\/p>\n
Additionally, confusing connection failures to LabQuest can occur if Logger Pro<\/i> is invoked and then put behind other windows on the Mac for a few minutes. Connecting a LabQuest to the computer in this state will result in Logger Pro<\/i> not seeing the LabQuest until it is brought to the foreground. Sometimes it can take a dozen seconds or more for Logger Pro<\/i> to wake up sufficiently to see and connect to the LabQuest in this scenario.<\/p>\n
To avoid these problems, update to the latest version of Logger Pro<\/i> if possible. Logger Pro<\/i> 3.9 (and above) prevent App Nap during critical data collection periods while allowing it when no data collection is taking place. In earlier versions of Logger Pro<\/i> running on 10.8 or 10.9, you may explicitly disable App Nap for Logger Pro<\/i>. Locate the Logger Pro<\/i> application in the Application folder, single-click it to select, and choose Get Info from the File menu. Select the Prevent App Nap check box. Close the dialog box. <\/p>\n
The issue has occurred with Logger Pro<\/i> 3.8.7 and earlier, as well as Logger Lite 1.7 and earlier. <\/p>\n
Logger Pro<\/i> 3.9 and Logger Lite 1.8 resolve the issue.<\/p>\n
Starting with Mac OS 10.10, the Prevent App Nap check box no longer appears. Users should upgrade to Logger Pro<\/i> 3.9 or later for use on Mac 10.10 and above.<\/p>","protected":false},"excerpt":{"rendered":"
