Apple unpublished old Mac OS X release notes

August 3 2026

In 2023 I published a blog post The myth and reality of Mac OS X Snow Leopard that included links to the release notes of some Mac OS X updates.

Well, let's look at the release notes for the 10.6.1 update:

[…]

It looks like the so-called "bug fix update" itself needed a number of bug fixes. How about the 10.6.2 update?

We're not done. Here's 10.6.3:

And 10.6.4:

Sadly, the links above now result in Page Not Found on Apple’s website.

The Wayback Machine last successfully archived these pages on December 31, 2023, not long after my blog post: 10.6.1 10.6.2 10.6.3 10.6.4. By April 30, 2024, the next time the Wayback Machine crawled these Apple URLs, they had all become Page Not Found: 10.6.1 10.6.2 10.6.3 10.6.4.

According to Google Search, these old Mac OS X release notes no longer exist anywhere on Apple’s website. For example, this is from Mac OS X 10.6.1:

• compatibility with some Sierra Wireless 3G modems

However, the search https://www.google.com/search?q=site%3Aapple.com+%22compatibility+with+some+Sierra+Wireless+3G+modems%22 returns no results.

From Mac OS X 10.6.4:

• resolve an issue that causes the keyboard or trackpad to become unresponsive

The search https://www.google.com/search?q=site%3Aapple.com+%22resolve+an+issue+that+causes+the+keyboard+or+trackpad+to+become+unresponsive%22 returns only an Apple Discussions thread the quotes the 10.6.4 release notes but not a link to release notes themselves.

Why is Apple erasing its own history?!? This seems needless.

Clearly, we must support the Internet Archive at all costs.

By the way, I published a follow-up The myth and reality of Mac OS X Snow Leopard revisited earlier this year.
