Other applications found on macOS 10.12 Sierra Mail adds a control to the top of email lists to quickly filter them, for instance, by read status or the presence of attachments. By signing the disk image, the developer can prevent tampering and force an attacker to repackage the files onto a new disk image, requiring a valid developer certificate to pass Gatekeeper without a warning. An attacker could infect these external files with malicious code and with them exploit a vulnerability in the application, without having to break the signature of the application bundle itself. This allows developers to guarantee the integrity of external files that are distributed alongside the application bundle on the same disk image. The file-hosting service Dropbox has been criticized for manipulating the directory to add their Dropbox application to the list, rather than asking the user to do it for them explicitly in System Preferences. Apple expanded System Integrity Protection to /Library/Application Support/com.apple.TCC, a directory that contains a list of applications that are allowed to "control the computer", and restricts write access to programs which were signed with an Apple "private entitlement". Directory permissions and sudo The Unix permissions for writing to the /Volumes directory are now restricted to root and no longer "world-writable". The user can avoid this mechanism by moving the application bundle without its external files to a new location. To avoid this, the developer has to distribute the application bundle and its external files on a signed disk image or in a signed installer package.
