Python Error using "ProductIO.readProduct"

Dear All,

I just started to use snappy to read .dim files (p=ProductIO.readProduct(’.dim’))
The following error appears every time.

2018-06-29 11:51:20.163 python[4991:125943] _LSScheduleNotificationFunction() failed on line 647 in function id scheduleApplicationNotification(LSNotificationCode, NSWorkspaceNotificationCenter *)

any ideas of what this error means?

Thank you.

The error does not come from SNAP or snappy.
It seems to be related to Apple and Mac.
I searched for it. Search Result

Thank you!

I will double-check my settings.
