The Choke of Invisibility

In today’s world, increasing privacy and security is generally a good thing for users. And no one takes privacy and security more seriously than Apple. Sometimes, though, an increase in privacy or security in one area or feature comes at a price: either complicating the end user experience, or breaking essential functionality of applications and services that are integral to a modern computing experience.

macOS Monterey 12.4 was released on Monday, May 16. It contains over 50 security fixes, and a number of important fixes for enterprise customers. This update also included Safari 15.5.


Almost immediately after updating, I noticed that some commonly-used websites were taking a very long time to load, or never finished at all. Others would appear to finish, but the “reload” button in the address bar continued to display an “x”, implying that an outstanding item was not yet loaded.

I decided to crack open the Web Inspector and start a Timeline Recording to see what was going on…

In the above image, you can see that most page resources have loaded, but two items remain outstanding…

The files spinning here are web open fonts aka WOFF2. These have been commonplace web design elements for at least a decade. Many websites license WOFF’s and load them remotely for convenience. In the above example, the US State Department is pulling them from Google.

Here is another example of a stalled resource @

This page is trying to load a very simple analytic tracker. If you load the URL directly in Safari 12.5, it loads without any issues. This one happens to be a 1×1 pixel, which is generally used for performance analytics to determine if a page loaded successfully. And, judging by the URL parameters, they are attempting to comply with GDPR by having a default value of gdpr=0, and the consent cookie gdpr_consent= has not yet been set.

I do not have iCloud Private Relay enabled on this Mac.


  1. Switch to another browser, such as Google Chrome or Firefox, OR:
  2. In Safari, uncheck “Hide IP address from trackers” as shown below.

The problem will be resolved immediately after reloading your desired webpage.

Strangely, this privacy feature has been available in several revisions of Safari 15.x, but this is the first known occasion where the feature breaks a boat load of websites and must be disabled to resolve it.

Once you allow a website to load with “Hide” disabled, it will not revert to its original behavior until you clear all cookies or reset Safari.

I’ve opened Feedback with Apple. Please file & dupe:

Though you might not hear back from Apple, please know they route the feedback to developers for investigation. The more people pile on, the faster they get it fixed.
