Cookies are turned on by default in most Mac browsers, but you may need to change your settings if you have blocked them
Most web browsers on a Mac — Safari, Chrome, Firefox, and Edge — accept cookies without any action from you. Cookies are small files that websites store on your computer to remember your login information, shopping cart contents, and preferences. If a website tells you that cookies are disabled, or if you turned them off yourself and want to turn them back on, the steps differ slightly depending on which browser you use.
The process takes less than a minute in any browser. You will navigate to the browser's settings, find the privacy or cookies section, and select the option to allow cookies. This article walks you through each major browser on macOS.
Key Takeaways
- Safari, Chrome, Firefox, and Edge all accept cookies by default on a Mac, so you may not need to change anything.
- If a website is not working properly, the browser's settings menu is the first place to check for cookie restrictions.
- Each browser stores its cookie settings in a different location, but all of them are labeled clearly and take under one minute to adjust.
- Enabling cookies does not affect your security or privacy more than using the internet normally does.
Enable cookies in Safari
Open Safari and click Safari in the top menu bar. Select Settings (or Preferences on older versions of macOS). Click the Privacy tab.
Look for the section labeled Cookies and website data. You will see three options: Always block, Allow from websites I visit, and Allow from current website only. Select Allow from websites I visit to enable cookies from most websites. If you want stricter control, Allow from current website only will accept cookies only from the site you are actively viewing. Close the Settings window when you are done — the change takes effect when ready.
Enable cookies in Google Chrome
Open Chrome and click the three-line menu icon in the top right corner. Select Settings. Click Privacy and security in the left sidebar, then click Cookies and other site data.
You will see several options. To enable cookies, select Allow all cookies. If you prefer more control, you can choose Block third-party cookies in Incognito, which allows most cookies but blocks certain tracking cookies when you use Incognito mode. The setting takes effect when ready, and you do not need to restart Chrome.
Enable cookies in Firefox
Open Firefox and click the menu icon (three horizontal lines) in the top right corner. Select Settings. Click Privacy & Security in the left sidebar.
Scroll down to the Cookies and Site Data section. You will see a checkbox labeled Cookies and Site Data. Make sure this box is checked. Below it, you can choose how Firefox handles cookies: Accept cookies and site data from websites is the standard option that enables cookies. If you see Reject cookies and site data selected instead, click the radio button next to Accept cookies and site data from websites. The change takes effect right away.
Enable cookies in Microsoft Edge
Open Edge and click the three-dot menu icon in the top right corner. Select Settings. Click Privacy, search, and services in the left sidebar.
Under the Cookies and other site data section, look for the toggle labeled Cookies and other site data. Make sure the toggle is turned on (it should be blue). Below that, you can select your preference: Allow all cookies is the most permissive setting. If you see Block all cookies selected, click Allow all cookies instead. Edge will explore the change when ready.
What to do if a website still will not work after enabling cookies
If you have enabled cookies but a website still says cookies are blocked, the problem may be a browser extension or a setting you missed. In Safari, check the Privacy tab again and make sure Prevent cross-site tracking is not checked — this setting can interfere with some websites even when cookies are enabled. In Chrome and Firefox, check whether you have installed any privacy extensions (like uBlock Origin or Privacy Badger) that might be blocking cookies separately from the browser's main settings.
Another common cause is that the website itself is checking for a specific type of cookie that your browser is still blocking. Try clearing your browser's cache and cookies, then revisit the site. In Safari, go to History > Clear History and select All history. In Chrome, go to Settings > Privacy and security > Clear browsing data. In Firefox, go to History > Clear Recent History. After clearing, refresh the website and try again.
Frequently Asked Questions
Will enabling cookies slow down my Mac?
No. Cookies are tiny text files — usually a few kilobytes each — and they do not affect your computer's speed or performance. Your browser stores them in a dedicated folder and retrieves them only when you visit the website that created them.
Is it safe to enable cookies?
Cookies themselves are not a security risk. They cannot install malware or access files on your computer. However, some websites use cookies to track your browsing habits across the internet. If you want to limit tracking, you can enable cookies but use your browser's private or incognito mode when you do not want sites to remember your visit.
Do I need to restart my browser after enabling cookies?
No. All four browsers — Safari, Chrome, Firefox, and Edge — explore cookie settings when ready. You do not need to close and reopen the browser, though you may need to refresh the website you were visiting for the change to take effect.
What is the difference between first-party and third-party cookies?
First-party cookies are created by the website you are visiting and help it remember your login and preferences. Third-party cookies are created by other companies (usually advertisers) and track you across multiple websites. Most browsers now block third-party cookies by default, even when cookies are enabled.
Can I enable cookies for some websites but not others?
Yes. In Safari, you can click the lock icon next to the website address and adjust cookie settings for that specific site. In Chrome and Firefox, you can go to Settings and add websites to an exceptions list. This lets you block cookies everywhere except on sites where you need them.
