Improve this answer. Tetsujin Tetsujin Thanks for the tips. I don't have a directory called Eagle inside the Safari app; did you mean to say "en"? I'm inclined to leave all of these alone, because they match on my other Yosemite machine. Still can't figure out why Disk Utility is confused. Really, Eagle [I've never spotted it before either] but not in Safari, in Library The Overflow Blog. Does ES6 make JavaScript frameworks obsolete?
Podcast Do polyglots have an edge when it comes to mastering programming Featured on Meta. The truth about repairing permissions lies somewhere in between. Every file and folder on a Mac OS X hard drive has a set of permissions —settings that determine which user s have access to each item, and exactly what that access is. For example, permissions dictate whether or not a particular user can open and edit a particular file. But permissions also determine which items the operating system—or specific parts of it—can access and modify, and which files are accessible by applications.
In Mac OS X For example, you may have trouble logging in to your account, printing, launching applications, or even starting up your Mac. Similarly, if an application—from Apple or a third-party developer—needs access to a particular file or folder to function, and the permissions on that item have changed in a way that prevents such access, the application may not function properly or at all.
The Repair Disk Permissions function can fix such problems by ensuring that certain files have the correct permissions. Repairing permissions can resolve such issues by resetting permissions on those files to prevent unauthorized access. After launching Disk Utility, select the desired disk—generally your startup disk—in the list to the left, then click the First Aid tab. This means that most of the files affected by the Repair Disk Permissions function are system-level files, application files, or system add-ons—not applications installed by drag-and-drop, and not your documents or other user-level files.
See the next section for information about third-party software. But beyond that, only certain receipts are referenced, all of them associated with OS-X-related software. This limitation of the Repair Disk Permissions function has been debated around the Web, but you can confirm it yourself with a bit of Terminal savvy: By using the. These receipts are explicitly listed within the code of DiskManagementTool , the component of OS X that actually performs the task of repairing permissions. You can verify this by using the following command in Terminal:.
The output from that command is a list of all receipts included in the code of DiskManagementTool. For example, I changed the permissions on the file NuFile. Since NuFile. If third-party receipts were used as references when repairing permissions, a piece of malware could leave behind a receipt designed to maliciously change permissions on system-level files—for example, to assign more-accessible permissions on normally secure files and directories.
