🧭 Three new Spotlight attributes… so far!

macOS Tahoe is quietly expanding Spotlight’s metadata attributes.

With Beta 2 just released, I’ll be digging deeper. For now, here’s what I’ve found so far.

Living life on the edge of frustrations with the #AppleDeveloper Beta's. πŸ˜… My thoughts on the visual aspect of #Apple's OS 26 family:
πŸ“± iOS: meh
πŸ’» macOS: love it
πŸ“Ί tvOS: subtle
⌚ watchOS: plain

We may have to start explaining the jump from iOS 17 to iOS 26 πŸ“±

It’s a rebrand, not 9 years of change. But in court, it can sound like it. Clarity matters when timelines are questioned βš–οΈ

APFS uses copy-on-write for metadata and most file data. When a file is modified, the new data is written to fresh blocks while the old data remains untouched until reused
Deleted data can persist in snapshots or unallocated space
