Is Repair Disk Permissions Dangerous To Files On Hard Drive
Repairing Disk Permissions is a simple procedure that Mac users can run with the Disk Utility app or through the command line, and, as the name suggests, information technology repairs the permissions of various files on the target drive. Repairing permissions can be helpful when troubleshooting some adequately specific issues, or after installing or uninstalling a gear up of Mac applications that may have erroneously modified permissions somewhere on a drive. This is a largely misunderstood procedure, so we're going to shine some lite on it, and if you're unfamiliar, how to resolve permissions issues with the repair process.
Nosotros'll discuss why you may want to repair permissions in a moment, but aside from resolving some specific permission related problems with files or folders in OS 10, whether user attributed or caused past modifying of removing software, the permission repair function is profoundly misattributed and is rarely the panacea of troubleshooting remedies that you lot may see ascribed to it, though that doesn't propose that you should not incorporate information technology into role of an occasional maintenance routine for a Mac. Practise keep in mind that when you're updating Bone 10, the repair permissions procedure is kicked off on information technology's own.
Beginning, permit's learn how to both repair and verify disk permissions (the latter of which really isn't necessary), then permit's larn a flake more virtually the process itself and why information technology would even be necessary.
Repairing Disk Permissions with Disk Utility in OS X
This will repair any discrepancies in permissions constitute with various files and folders on the target disk connected to the Mac. You can do this with a boot volume or external drive, or both, it doesn't matter which.
- Open the Disk Utility application in OS Ten (located in /Applications/Utilities/)
- Select the disk from the left side menu to repair permissions for
- Go to the "First Aid" tab and click the "Repair Disk Permissions" button and let the process run from start to finish – this may take a while depending on the size and speed of the difficult drive
You will likely see multiple letters stating that various files and directories have been "Repaired" subsequently finding differing permissions, which volition look something like this:
Permissions differ on "Applications/.DS_Store"; should exist -rw-rw-r– ; they are -rw-r–r–
Repaired "Applications/.DS_Store"
Group differs on "Library/Printers/PPDs/Contents/Resources"; should be 80; group is 0.
Repaired "Library/Printers/PPDs"
When finished, you volition come across a "Permissions repair complete" message appear in the Disk Utility console. If you take multiple hard drives or volumes fastened to the Mac, y'all may as well run the procedure again on the other drive while you're in hither.
Verifying Disk Permissions on a Mac with Disk Utility
The verification process can unremarkably be skipped, all it does is cheque to see if in that location are any improper permissions bug that tin be resolved with the repair function. All the same, it can be good practice to run the verify procedure anyway, but since in the repair process things will be verified anyway, we'll comprehend it 2nd:
- If you haven't already, open up the Disk Utility app, establish in the /Applications/Utilities/ folder (or attainable through Spotlight by hitting Control+Spacebar)
- Select the deejay in question that you lot wish to verify permissions for
- Nether the "First Aid" tab, click the "Verify Disk Permissions" button and let the process run
Nearly all Mac users who run verify (or repair) will notice that some permissions are off, unremarkably with obscure files in the temporary or Library folders, thus don't be alarmed if you meet things pop up with messages similar:
"Group differs on "Library/Printers/PPDs/Contents/Resources"; should be lxxx; group is 0."
"Permissions differ on "Applications/.DS_Store"; should be -rw-rw-r– ; they are -rw-r–r– "
If you exercise come across any differing permissions, go ahead and run the Repair function next. Or you tin spring directly to repair without verifying, there is no harm in doing so.
Why Repair Disk Permissions on a Mac?
Permissions for some files and folders will inevitably change, whether because a user modified the permissions of a file or folder that they shouldn't have, or because of the installation or removal of an awarding or utility. Taking the latter instance, sometimes installing and uninstalling an application can upshot in some files with specific permissions being inverse from, say, only existence writable past the active user to being universally writable (or non writable at all), or vice versa, thus leading to some permissions errors when that file is existence accessed in the future. In almost cases, these inconsistencies with specific file permissions won't impact applications, performance, or anything else notable on the Mac, only in some relatively rare circumstances they can cause trouble, leading to either erroneous beliefs in Bone X. In an extreme example of a problem generated past improper permissions, the completely broken display of system fonts showing up as wild characters rather than the text you'd await to see can be issue of the arrangement fonts folder having improper permissions and being attributed to the wrong user or grouping.
Because differing permissions on files or folders, either with or without consequences, is well-nigh guaranteed to happen over time when using a Mac and installing and uninstalling a variety of applications, repairing permissions is worthwhile on an occasional footing. Feel complimentary to add together it to the list of maintenance to perform on some semi-regular ground for a Mac, just don't expect information technology to perform any miracles or speed upwards your Mac, that's just not how it works.
And yes, the permissions repair procedure is identical in all versions of OS X with the Deejay Utility app, regardless of whether the Mac is running Yosemite, Mavericks, Mountain Lion, Tiger, Leopard, or any else. Similarly, the procedure works whether you're booted normally, in unmarried user style, or from a repair drive.
