As a general Mac user, hopefully you’ll never need to get into manually fixing permissions and ACL settings on files buried in your Mac OS. But if you do, what are the options?
How to change permissions for files, folders, or disks Assign permissions to users and groups. On your Mac, choose a file or folder. Right-click it and select Get info. Apply permissions to all files in a folder/disk. Choose a folder or disk. Select File Get Info. Click the lock icon. This app by no means provides you a dashboard to change what permissions an app has. If you want to revoke any special access that you’ve given to an app, you’re going to have to go through System Preferences. You should know that not all permissions can be revoked e.g., many apps may have access to photos on your Mac. There is no way for.
There are plenty of instructions on the Internet giving the details of changing permissions in Finder and in Terminal. Terminal provides options more powerful that what Finder provides. But it’s complicated. I was looking for a free or cheap app to give me full control over permissions and ACL settings for any file on my Mac. I found exactly what I needed.
Setting Permissions On MacIntroducing PropEdit
PropEdit (
UPDATE: The developer of this app is kindly making it available free, as he is no longer developing it. I am using it on Mountain Lion 10.8.3 with no issues, to my knowledge. You can legally use the following key to register it: 0GYF-CMX2-49X3-B1VH-8CA9 – Thank you to Jonas for pointing this out in the comments.
PropEdit is a great tool for doing exactly what I described above. You can do all of the following with it, and more:
I was having issues with a file utilised by the Sparkle update system. I noticed it had something like 5 ACL entries for my user name, and I wanted to remove them and clear it up. https://poyellow967.weebly.com/mac-cool-down-app.html. Here’s a screen shot of PropEdit whilst I was access the file:
You’ll notice the ACL Editor button to the bottom right. That’s where I got access to the messed up ACL settings, cleaned them out, and set new ones.
Here is a picture of the built-in ACL editor:
PropEdit does cost $5, and there are numerous free alternatives to perform similar functions. None of the alternatives I tried were quite a polish and comprehensive as PropEdit, but if you only need to do a once-off repair I am sure these free apps will work just fine. Below are notes for apps I tried.
Other Options (all free)
There are quite a few applications providing the kind of functionality I have detailed for PropEdit. Here is a list:
BatChmod (free) – It doesn’t have a full ACL editor. But otherwise allows you to clear all ACL settings. It doesn’t allow for setting Flags. The following image shows what it can do:
ACL Fix (free) – solely for removing all ACL settings from a folder, file, or batch of files/folders. Nice and simple if you need to resolve ACL issues on folders copied into a system from a backup, for instance.
Sandbox (free) – This app is still not as nice as PropEdit. It does give access to full ACL editing though, and setting of standard permissions. The file browser it uses is not the default Cocao/OS X one, so it is not possible to use the Go To Folder keyboard shortcut. This means if you need to edit a deeply buried file, which you have already located in Finder, you can’t simply copy its full path and then use Go To Folder in Sandbox to jump directly there.
Inbox gmail app mac. In my experience Sandbox is the best free option. It is almost as good as PropEdit, but without the $5 pricetag. If I was working with file permissions and ACL settings a lot, I would go with PropEdit. But otherwise I’d use Sandbox.

As long as you have administrative access to your Mac computer, you can change the permissions for a file, folder or disk on the Mac from 'Read Only' to 'Read & Write.' This is important to know if you want a coworker to collaborate on one of your files or if you need to modify a file someone sent to you that came as 'Read Only.' If the file is on someone else's computer or on a shared drive, you can't change the permissions unless you created the file or have administrative access to that drive.

Mac OS X Hidden Files & Directories 206-522-3530 Reference • • • • Mac OS X Hidden Files & Directories By Gordon Davisson Copyright (c) 2005, Westwind Computing inc. Mac OS X volumes contain quite a few files and directories (aka folders) that are invisible from the Finder (and many other interfaces). For the most part, they're hidden for good reason -- you generally don't need to worry about them, and in fact, probably shouldn't muck with them unless you know what you're doing. But just in case you find yourself needing to deal with them, here's a quick summary of what they're for.
Mac OS X Hidden Files & Directories._whatever These files are created on volumes that don't natively support full HFS file characteristics (e.g. Ufs volumes, Windows fileshares, etc). When a Mac file is copied to such a volume, its data fork is stored under the file's regular name, and the additional HFS information (resource fork, type & creator codes, etc) is stored in a second file (in AppleDouble format), with a name that starts with '._'. (These files are, of course, invisible as far as OS-X is concerned, but not to other OS's; this can sometimes be annoying.).DS_Store This file in created by the Finder to keep track of folder view options, icon positions, and other visual information about folders. A separate.DS_Store file is created in each directory to store information about that directory, so you'll find them appearing all over the directory tree, in pretty much every folder you've visited with the OS X Finder. ~/.Trash Used to store files & folders from the boot volume that a particular user has thrown in the trash, but that haven't been erased yet.

/.Spotlight-V100 Used to store metadata indexes and indexing rules for Spotlight (version 1.00 apparently). Only created under Mac OS X 10.4. /Volumes/(whatever)/.Trashes On volumes other than the boot volume, a.Trashes folder is used to hold files & folders that've been put in the trash but not yet deleted. Since each user has their own personal trash can, subfolders are created under.Trashes for different users, named according to their user ID number. For example, if user #501 throws something on a volume named 'Data' into the trash, it'd be moved to a directory named /Volumes/Data/.Trashes/501/. Permissions on this folder are set so that you can only access a trash can if you can guess the users' ID -- that is, you cannot view a list of which users actually have trash cans in existance.
