If Anti-Malware for Mac reports that it is unable to access certain folders, or has a problem removing adware, you may have a permissions problem.


Repairing system permissions

Open Disk Utility (found in the Utilities folder in the Applications folder) and use it to repair the permissions on your hard drive. This will not touch the permissions on things inside your user folder, but will correct any issues with system-owned folders. Be aware that there may be a number of issues reported that may not represent any problems. See Apple's site for more details, 

Mac OS X: Disk Utility‘s Repair Disk Permissions messages that you can safely ignore.


Repairing user folder permissions

  1. Restart your machine
  2. While your computer is restarting, hold down command+R
  3. When you see the Apple logo, you can let go.
  4. This will start your machine in recovery mode, which allows you to do things like reinstall the system.
  5. Once in recovery mode, click the Utilities menu and then click Terminal
  6. When Terminal opens, type the following: resetpassword
  7. Once you have typed this, press Return
  8. A Reset Password window should open.
  9. At the bottom, under Reset Home Folder Permissions and ACLS, is a Reset button. Click this.
  10. When the procedure finishes, restart your computer normally


Repairing Safari's Extensions folder

In certain rare cases, when Anti-Malware for Mac reports that it cannot access Safari's Extensions folder, the above solutions will not fix the problem. If this happens, the best thing to do is delete the Extensions folder and allow Safari to re-create it.

  1. Quit Safari
  2. Launch Finder
  3. Click the Go menu, then click Go to Folder
  4. Paste the following text into the window that opens: ~/Library/Safari/
  5. Click the Go Button


This should display the contents of this Safari folder in a Finder window. One of the items there will be a folder named Extensions. Move that folder to the desktop.


When you re-open Safari, it will re-create this Extensions folder. Test Anti-Malware for Mac and make sure it's working properly. If it is, open the Extensions folder on your desktop (if you can) to find any extensions that were removed. If you want to reinstall any of them, simply double-click them. Once you have reinstalled anything you need to, drag the Extensions folder from your desktop into the trash
