As a movie fan, I check out the iTunes Trailers website on a regular basis. And on a regular basis, I get this message: “It looks like you need to reset your browser cookie for iTunes Trailers. We suggest you delete your trailers.apple.com and apple.com browser cookie(s) and then restart your browser.” Let’s look at how you do this.
First, note that websites often store cookies and other data on your Mac. This data may include information that you have provided, such as your name, email address, and preferences. This data helps websites identify you when you return so the site can provide services for you and show information that might be of interest to you.
By default, Safari accepts cookies and website data only from websites you visit. This helps prevent certain advertisers from storing data on your Mac. You can change options in Safari preferences so that Safari always accepts or always blocks cookies and other website data.
You should know that changing your cookie preferences or removing cookies and website data in Safari may change or remove them in other apps, including Dashboard. If that’s okay, then you can choose Safari > Preferences, click Privacy, then do any of the following:
- Change which cookies and website data are accepted: Select a “Cookies and website data” option:
- Always block: Safari doesn’t let any websites, third parties, or advertisers store cookies and other data on your Mac. This may prevent some websites from working properly.
- Allow from current website only: Safari accepts cookies and website data only from the website you’re currently visiting. Websites often have embedded content from other sources. Safari does not allow these third parties to store or access cookies or other data.
- Allow from websites I visit: Safari accepts cookies and website data only from websites you visit. Safari uses your existing cookies to determine whether you have visited a website before. Selecting this option helps prevent websites that have embedded content in other websites you browse from storing cookies and data on your Mac.
- Always allow: Safari lets all websites, third parties, and advertisers store cookies and other data on your Mac.
- Remove stored cookies and data: Click Remove All Website Data, or click Details, select one or more websites, then click Remove.
When you click details you can see which websites store cookies or data. You can then select a listed website, click Remove, and the cookies/data for that site is removed. That’s what I do to remove the trailers.apple.com and apple.com browser cookies.
