You’ve probably been there. You're trying to read a recipe or a news article on your Mac, and suddenly the screen is buried under three different pop-ups, a sticky video player in the corner, and a "sign up for our newsletter" banner that won't go away. Naturally, you go looking for the gold standard of ad blocking: uBlock Origin for Safari.
But here's the kicker. It’s not there.
If you open the App Store or search the Safari Extensions gallery, you’ll find a dozen imitators, clones, and things with suspiciously similar names, but the real deal—the one maintained by Raymond Hill (gorhill)—isn't available. It hasn’t been for years. This isn't just a minor oversight or a developer being lazy. It’s actually a pretty dramatic story of how Apple changed the rules of the game for how browsers work, effectively killing off one of the best pieces of software ever written for the Mac.
Honestly, it’s frustrating. People love uBlock Origin because it’s lean. It doesn't hog your CPU. It doesn't have an "Acceptable Ads" program where companies pay to get their trackers whitelisted. It just works. But on Safari, the door is essentially locked.
The Technical Wall: Why uBlock Origin Broke
To understand why you can't just download uBlock Origin for Safari anymore, we have to talk about 2018. That was the year Apple announced they were moving away from "Legacy Safari Extensions."
See, back in the day, extensions had a lot of power. They could see almost everything the browser was doing. This was great for blocking ads because the extension could look at a web request and say, "Nope, that's a tracker, kill it," before the page even loaded. But Apple, being Apple, decided this was a privacy and performance nightmare. They introduced the Safari App Extension framework and eventually moved toward Content Blocker APIs.
This changed everything.
Instead of the extension doing the heavy lifting, Apple demanded that the extension hand over a list of "rules" to Safari. Then, Safari would do the blocking itself.
The gorhill Perspective
Raymond Hill, the creator of uBlock Origin, was pretty vocal about why this wouldn't work for his vision. The new API (Content Blocker) had a strict limit on the number of rules you could use. At the time, it was around 50,000. That sounds like a lot, right? It’s not. A standard setup for uBlock Origin often involves hundreds of thousands of rules to catch the latest sneaky trackers and malware domains.
Because of these technical shackles, the "real" uBlock Origin couldn't function. It couldn't be the power tool it was designed to be. So, rather than release a watered-down, "gimped" version of his work, Hill stepped away from the Safari platform. He's a purist. If it can't be done right, he's not doing it. You have to respect that, even if it leaves Safari users in the lurch.
Beware the Impostors
If you search for "uBlock" in the Mac App Store right now, you’ll see results. Do not be fooled.
There is a version out there often called "uBlock" (without the "Origin" suffix) that is owned by a completely different entity. There was a whole mess of a legal and ethical dispute years ago where the original "uBlock" name was handed off, and the original developer started "uBlock Origin" to stay true to the open-source, non-commercial roots.
Many of the apps you see today using that name are actually based on older code or are just trying to capitalize on the brand recognition. Some of them even engage in the very tracking they claim to prevent. It's a bit of a minefield. If it isn't the version maintained by gorhill, it isn't the uBlock Origin the internet keeps telling you to get.
What Actually Works on Safari Today?
So, if uBlock Origin for Safari is a ghost, what are you supposed to do? You aren't just stuck with ads. There are a few legitimate contenders that have figured out how to work within Apple's strict Content Blocker rules.
AdGuard for Safari is probably the closest you’ll get to the "pro" experience. They’ve managed to get around the 50,000-rule limit by splitting their extension into multiple "content blockers" that run simultaneously. It’s a clever workaround. One handles privacy, one handles social widgets, one handles general ads. When they all work together, it feels almost as powerful as uBlock.
Then there is Wipr.
Wipr is the "set it and forget it" option. It costs a couple of bucks, but it’s incredibly lightweight. It doesn't have a fancy dashboard where you can toggle individual elements or see a live log of every blocked request. It just sits there and quietly scrubs the web. For my parents or people who don't want to play with filter lists, this is usually what I recommend.

The "uBlock Origin" Workaround: Orion and Others
If you absolutely, positively must have the real uBlock Origin on a browser that feels like Safari, you should look at the Orion Browser.
Orion is built on WebKit—the same engine Safari uses—so it feels very native to macOS. However, the developers did something pretty wild: they built in support for Chrome and Firefox extensions. You can actually go to the Chrome Web Store inside Orion and install the real uBlock Origin.
It’s not 100% perfect. Since it's a bit of a "hack" to get those extensions running on WebKit, you might run into a bug here or there. But if you're a die-hard Safari fan who just can't live without gorhill’s masterpiece, this is the most viable path.
Another option, though it moves you away from Safari entirely, is Brave. It has a native "Shields" system that is written in Rust and is incredibly fast. It’s not uBlock, but it’s inspired by the same philosophy of efficiency.
Why Apple's Restrictions Might Actually Be Good (Mostly)
It’s easy to get mad at Apple for killing our favorite extension. But there is a flip side. By forcing ad blockers to use the Content Blocker API, Apple ensures that the extension can't actually see your browsing history.
In Chrome, a traditional ad blocker has to "read and change all your data on the websites you visit." That’s a massive security risk if the extension ever gets sold to a shady company or gets hacked. In Safari, the extension just hands a list to the browser and says, "Hey, don't load these." The extension never knows which specific site you're on or what you're typing.
It’s a trade-off: you lose the "god-mode" blocking power of uBlock Origin for Safari, but you gain a layer of systemic privacy that's built into the OS.
Setting Up Your Safari Defense
Since you can't just click "Install" on uBlock, here is the best way to get a clean browsing experience on Safari right now.
First, download AdGuard for Safari from the App Store. Once it’s installed, you’ll notice it asks you to enable about five or six different extensions in Safari’s settings. Do all of them. Each one represents a different category of filters.
Next, go into the AdGuard settings and enable "Annoyances." This is the secret sauce. It’s what gets rid of those "Cookie Consent" banners and "Allow Notifications" prompts that are often more annoying than the ads themselves.
If you find a site is broken, you can easily whitlelist it by clicking the little icon in the search bar. It’s not as "cool" as the uBlock dashboard, but it’s 90% of the way there.

Actionable Steps for a Cleaner Safari
- Check your current extensions: If you have something just called "uBlock" or "uBlocker," delete it. It’s likely a knock-off using your RAM for no reason.
- Trial a Content Blocker: Download AdGuard or 1Blocker. Both have free tiers that are significantly better than nothing.
- Update your OS: Apple frequently updates the Content Blocker API. Staying on the latest version of macOS or iOS ensures those blockers can use the newest "rules" allowed by the system.
- Consider a DNS-level solution: If you want to go hardcore, look into NextDNS. It blocks ads at the network level before they even reach your computer, which is a great backup for when browser extensions fail.
The dream of a native, official uBlock Origin for Safari is effectively dead due to the architectural differences in how Apple wants browsers to work. It’s a bummer, but the alternatives have matured a lot. You don't have to settle for a cluttered web; you just have to change your toolkit.
