I need to toggle a boolean (NSHighResolutionCapable = false) in the Info.plist for VirtualBox to allow my Windows 10 to run smooth.

Before Ventura this could be done by changing the the sharing/permissions followed by editing with any editor.

Now that I have migrated to Ventura (and installed Virtualbox 7) I am unable to edit Info.plist in /Applications/VirtualBox.app/Contents/Resources/VirtualBoxVM.app/Contents

What is the correct procedure to do this?

    In what way are you "unable" to edit it? What happens when you try? I can edit Info.plist files of apps in BBEdit under Ventura, without changing any file permissions.

  • @benwiggy When I edit the Info.plist and want to write it back to disk I get "You don’t have permission to write to the folder that the file “Info.plist” is in." And now I know the answer - I must give myself write access not to the file but to the folder.

Answering my own question, many thanks to @benwiggy - give yourself read/write access to the folder in which Info.plist is found, in this case the Contents folder.

After that, you can change the Info.plist with the editor of your choice.

    That's not new. That's the way permissions have always worked. Perhaps the permissions on the containing directory are different than they were previously. Nov 7, 2022 at 14:44
  • I'd suggest using a method that doesn't alter the app's file attributes. As said, you should be able to do this using BBEdit.
