By default, when you run the Cleaner, CCleaner deletes all of the cookies for all of your Web browsers (Safari, Mozilla Firefox, Opera, and so on). There are two ways to keep cookies on your Mac while still making full use of CCleaner.
Option 1: To keep all cookies on your Mac
- In the left pane of CCleaner for Mac, click Mac OS X.
- On the Mac OS X tab, under Safari, clear the Cookies checkbox.
- If you have no other Web browsers installed, you have finished. If not, click the Applications tab.
- Under each browser listed, clear the Cookies checkbox.
From this point on, whenever you run the Cleaner, it will retain all cookies from these browsers.
Option 2: To keep certain cookies on your Mac
- In the left pane of CCleaner for Mac, click Options, and then click Cookies.
- The list may take a few seconds to load. This list displays cookies from all the browsers you have installed on your system.
- By default, all cookies are in the Cookies to Delete column. To keep cookies, move them to the Cookies to Keep column by selecting cookies and clicking the right-arrow button. You can select multiple cookies by using CMD+click, or select a set of cookies in a row by clicking the first one and then SHIFT-clicking the last one.
- If you use the method in Option 1 to keep all cookies on your Mac, the cookies in the Cookies to Delete column will not be deleted.
- If you have a long list of cookies, you can easily search through them for the ones you want. Click inside the Search box and type a few letters in the cookie's domain name. For example, typing HOO will return cookies for Yahoo.com.
