Webkit.WebContent?

Safari has been acting strangely for the last few weeks. Today's problem is this dialog box:


User uploaded file

It appears every time I open Safari.


I have no idea what this dialog box means. Does anyone know?


(I have removed the title of my authentication from this screen shot.)

Mac mini, macOS Sierra (10.12.6)

As per this article Applications don't work after reinstalling Mac OS X - Apple Support


Example 2: Software developers or system administrators may have installed multiple versions of Mac OS X in order to perform tests. This issue can occur if you install a later version of Mac OS X on one volume, then start up from an earlier version that is on a different volume.


Many Apple applications are not entirely self-contained, but rely upon "frameworks". When these frameworks are shared by many applications, they are not contained inside the application. For example, many Apple applications that draw web pages or other HTML content use Apple's "WebKit" framework. That framework is used by the Safari, Mail, Help Viewer, Software Update and Installer applications. WebKit is stored in /System/Library/Frameworks/WebKit.framework/ .


Some application versions work only with specific framework versions. If you have installed a newer version of an Apple application, it may have installed a newer version of the framework as well. Sometimes installing a Mac OS X software update will update an application to a newer version. If you later reinstall or Archive and Install that version of Mac OS X, the newer application's are retained but the older frameworks are reinstalled. The easiest way to resolve the issue is to reapply the application or OS updates you previously had. If this is not an option, you should delete the application that is not working and reinstall the application or Mac OS X update you previously had.

I did not find anything pertinent at those four locations.


I had never noticed Notifications before. I may use it again.


I have the Suggestions preference on. AFAIK I have always had this preference selected.


I do not subscribe to any feeds, and I have only one Twitter link. (That Twitter user has not used Twitter in years.) I did not find anything of interest in either of those locations.


Earlier this afternoon, when the dialog box popped up again, I clicked the Always Allow button. So far this afternoon the dialog box has not reappeared.

You're better off finding out what website is soliciting your Apple ID credentials than simply acquiescing to what appears to be some random demand for them. I recommend denying the request, then opening Safari's Preferences... > Passwords. Review them, and at your option, delete some or all of them. Obviously you will want to have recorded those passwords elsewhere, so if you didn't already do that, do it before deleting them. When prompted for passwords on the various websites that require them, at your option elect to have Safari remember them again.


Another suggestion is to use Privacy > Manage Website Data... and Remove All. That will disable automatically logging in to sites that offer that option, until you enable it again.


See if that stops the nag.
