2025 Guide: How to Allow 3rd Party Cookies on Mac Easily

While browsing, I encountered a website loading issue on my Mac, which made look for the source. Turned out, it were the “cookies” that caused the entire issue. Since the third-party cookies are blocked by Chrome and Safari, I’ve had login issues and payment gateways breaking in the middle.

If you’ve faced the same issues, I’ll show you exactly how to allow 3rd party cookies on Mac. Plus, I’ll share how I delete and manage cookies in Safari and Chrome when I don't need them. Towards the end, I’ll also share how I secured my sensitive documents via a safe PDF manager, UPDF.

Part 1. Why Do Cookie Settings Make a Difference on My Mac?

Cookies are small files that websites store on the user’s device via web browsers to remember login information and unique identifiers. They help websites recognize returning visitors and track saved items in shopping carts, so that I don't have to repeat steps every time I visit a site. That’s why I’ll let you know how to allow third-party cookies on Mac, which saved me plenty of time.

While third-party cookies are associated with tracking across sites, I’ve also noticed that many embedded services and certain apps won’t work unless I allow them. Since Safari and Chrome block them automatically, I learned how to adjust the settings myself, letting me choose when to allow them and when to leave them for privacy.

Part 4. Bonus Tip: Stay Secure While Working on a Mac with UPDF

Now that you completely know how to allow third-party cookies on Mac, it’s also important to understand the security of documents while working. I often work on super private documents and reports, so I needed a reliable PDF manager that protects my documents without risking privacy. That’s why I turned to UPDF, which served as a safe workspace and helped me manage sensitive files without worry.

According to the UPDF’s cookie policy and privacy policy, they don't misuse users’ data, which gives me peace of mind. Beyond trust, UPDF also offers file protection features to keep secret files safe.

2. Redaction Tools: Through this tool, I can easily remove sensitive information from the document for public use. It allows me to search for specific terms and redact them all in a single click, along with the full redaction.

This tool also offers a PDF sanitization feature that helps erase all hidden metadata in the document.

4. Protect PDFs with a Watermark: UPDF protects my PDF from unauthorized usage by allowing me to put a text watermark and edit the text for better visibility. I can use an image of a PDF file as a watermark and can rotate, adjust its opacity, and select a custom page range for the watermark.
