I don’t know why. For some reason on my M4 Mac mini in Tahoe 26.2 Beta (25C5048a), the default system icon for .bundle files is a Microsoft Word 2004 icon. I do have Microsoft Office installed, but surely it’s not that old!

As it turns out, there’s an explanation for this.

In my tired mind while chuckling at the circumstance, I posted about it in the LEM group, and got a few different responses. Most notably, however – is isn’t actually a bug!

• Response: “..because in the beta you’re running (Tahoe 26.2), the bundle’s icon metadata is missing or malformed, and Finder is falling back to whatever icon is registered for one of the UTIs the system thinks the bundle touches. Microsoft Word registers extremely broad document UTIs on macOS—broad enough that when a system bundle is missing its proper metadata, Finder sometimes picks up Word’s icon as the fallback. It’s a quirk that shows up in several macOS betas.”
