The delayed updates of applications, the delayed upgrades of the operating system of Mac, or the expired account information caused by updates of apps or operating systems, all mentioned may be the reasons causing 'Couldn't communicate with a helper application' on your Mac.

Helper Helper is a community service app that connects volunteers to meaningful experiences in the community.
