helper installer

It would appear then that the helperinstaller is associated with MuseScore and should be allowed.

Also, check System Preferences > Security and Privacy > Privacy > Files and Folders. If MuseScore is not already listed there, add MuseScore and select "Documents" and "Downloads" folders to give MuseScore permission to access those folders. Alternatively, you could give MuseScore full disk access.

Hey there omits,

Thanks for reaching out to the Apple Support Communities.

To get started, did this message pop up while trying to install an app or some other software on your Mac? If so, then it would be okay to go ahead and grant permission. However, if you did not start to install an app, we would recommend not granting permissions to the process.

For more details, check out this link here: Safely open apps on your Mac - Apple Support

We hope that's able to help.

Take care!

There are many apps that use a "helper" application. Does the message give any indication of what app your helperinstaller may be associated with?

Here are a few common apps that use helpers. Do you have any of these apps installed?

• Adobe CC (Photoshop, Lightroom, Acrobat, etc)
• Skype
• Dropbox
• Carbon Copy Cloner
• OneDrive
