Safari does not install extensions

For those of us who can't read Russian, could you please translate the error message, or temporarily switch your system language to English.

Problems such as yours are sometimes caused by files that should belong to you but are locked or have a wrong owner. This procedure will check for such files. It makes no changes and therefore will not, in itself, solve your problem.

Launch the Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ If you’re running OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.

Drag or copy — do not type — all of the next line into the Terminal window, then press return:

find . $TMPDIR.. -flags +sappnd,schg,uappnd,uchg -o ! -user $UID

The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.

Post any lines of output that appear below what you entered — the text, please, not a screenshot.

If any personal information appears in the output, edit before posting, but don’t remove the context.

The procedure below will reset the permissions of a home folder in OS X 10.7.4 or later. If you're running an earlier version of 10.7, update to the current version first. This procedure should not be used in OS X versions older than 10.7.4.

Back up all data.

Step 1

Click the Finder icon in the Dock. A Finder window will open.

Step 2

Press the following key combinations, in the order given:

Command-3

Shift-command-H

Command-I

The Info window of your home folder will open.

Step 3

Click the lock icon in the lower right corner and authenticate with the name and login password of an administrator on the system. If you have only one user account, you are the administrator.

Step 4

In the Sharing & Permissions section of the window, verify that you have "Read & Write"privileges. If not, use the "+" and "-" buttons in the lower left corner to make the necessary changes.

Step 5

By default, the groups "staff" and "everyone" have "Read Only" privileges. With those settings, the files at the top level of your home folder will be readable by other local users. You can change the privileges to "No Access" if you wish, but then your Public and Drop Box folders will be inaccessible to others, and Personal Web Sharing won't work. Most likely, you don't need to change these settings.

Step 6

If there are entries in the Sharing & Permissions list for users or groups besides "me," "staff," and "everyone," delete them.

Step 7

Click the gear icon at the bottom of the Info window and select Apply to enclosed items... from the drop-down menu. Confirm. The operation may take several minutes to complete. When it does, close the Info window.

Besides Aliste 's you saved my day too. I had the same problem since Safari 5. Applies your advice above and worked like a dream.

Thanks again.

Can you please direct me where to reset permissions in order to accomplish same in OSX 10.6.8? I am getting the same error message when attempting to install extensions. When I log out as admin and log in as guest I can install. Clearly I have befouled my permissions.... THANKS!!

Hi:

Thank you
