Several issues may cause the LabChart 7 for Mac software to fail to recognize a PowerLab connected to your computer.
Generally, turning the PowerLab off and on again will resolve the issue. If repeated attempts fail to resolve the case, the cause may be that settings in the preferences have been set to launch LabChart in Analysis mode.
Launch LabChart 7 for Mac and select LabChart > Preferences > PowerLab Startup:
Open the PowerLab Startup menu and make sure the "Always start in analysis mode" is unchecked:
Click OK. This solution applies to LabChart for Mac 7. x.
