Living life on the edge of frustrations with the #AppleDeveloper Beta's. 😅 My thoughts on the visual aspect of #Apple's OS 26 family:
📱 iOS: meh
💻 macOS: love it
📺 tvOS: subtle
⌚ watchOS: plain
🕶️ visionOS: TBD

📲 It’s that time again! iOS 26 Beta just dropped—and for forensic examiners, that means new logs, artifacts, and security changes are coming. Time to dig in! 🔍 #iOS26 #DFIR #AppleForensics #DigitalForensics #WWDC25

🔐 Most iPhones already run iOS 18. That’s a challenge for #DFIR.

📱 82% of all iPhones
📊 88% of devices from last 4 years

Forensic hurdles:
• Users enabling Lockdown Mode
• Stolen Device Protection
• USB Restricted Mode
• Auto reboot = AFU → BFU

We may have to start explaining the jump from iOS 17 to iOS 26 📱

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

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
