[Image Recommendation]:

Option A (Real UI Screenshot): A clean macOS Disk Utility screenshot showing an APFS Container with Macintosh HD (System Volume, Read-Only) and Macintosh HD - Data (Data Volume) highlighted in the sidebar.
Option B (Flat 2D Technical Diagram Prompt): "A clean 2D technical architecture diagram showing an APFS Container split into two labeled layers: 'Macintosh HD (System Volume, Read-Only)' on top and 'Macintosh HD - Data (User Data)' below, connected by clean gray lines labeled 'Firmlinks'. Flat 2D vector style, Apple technical documentation aesthetic, white background, no 3D effects, no glowing elements, crisp black text."

Subtitle: מהפיכת APFS

Bullets:

[Image Recommendation]:

Option A (Real UI Screenshot): A macOS Disk Utility window showing the APFS Container storage bar, illustrating shared free space dynamically allocated across multiple APFS volumes (Macintosh HD, Macintosh HD - Data, Preboot, Recovery).
Option B (Flat 2D Technical Diagram Prompt): "A clean 2D technical diagram illustrating APFS Space Sharing. A single rectangular container box labeled 'APFS Container (500 GB)' contains three nested volume boxes of different sizes ('System', 'Data', 'Recovery'). A dashed arrow points to a shared pool of free space labeled 'Free Space (Shared Pool)'. Flat 2D minimalist vector, Apple tech guide style, clean lines, white background, no fluid effects, no 3D."

Subtitle: הפרדת המערכת (SSV)

Bullets:

[Image Recommendation]:

Option A (Real UI Screenshot): A macOS Finder window showing the root Macintosh HD directory with a read-only lock badge, alongside a Terminal window executing mount showing / mounted as read-only (ro) and /System/Volumes/Data mounted as read-write (rw).
Option B (Flat 2D Technical Diagram Prompt): "A clean 2D technical block diagram comparing legacy OS layout vs. macOS SSV layout. Left side: single unencrypted volume box ('System + Data'). Right side: two isolated volume boxes ('System Volume (SSV - Sealed & Signed, Read-Only)' with a small blue lock icon, and 'Data Volume (User Files, Read-Write)'). Minimalist flat 2D vector, corporate IT presentation style, clean white background."

Subtitle: מנגנון ה-Firmlinks

Bullets:

[Image Recommendation]:

Option A (Real UI Screenshot): A Terminal window showing the output of cat /usr/share/firmlinks listing real firmlink paths like /Users, /Applications, /Library, /Users/Shared alongside a Finder window showing seamless navigation across those folders.
Option B (Flat 2D Technical Diagram Prompt): "A clean 2D technical architectural flowchart showing how Firmlinks merge two volumes. Box A on left labeled 'System Volume (Read-Only)', Box B on right labeled 'Data Volume (Read-Write)'. Solid black arrows labeled 'Firmlink' point from System folders ('/Users', '/Applications') into Data Volume folders. A merged box below shows 'Unified Finder View'. Flat minimalist 2D vector diagram, clean white background, no glowing effects, no 3D."

[Image Recommendation]:

Option A (Real UI Screenshot): A macOS Spotlight search bar overlay on desktop searching for a complex query, alongside a Terminal window executing sudo mdutil -s / and mdimport -L showing active metadata importers and indexing status.
Option B (Flat 2D Technical Diagram Prompt): "A clean 2D technical flowchart of Spotlight metadata indexing. A document icon enters a box labeled 'mdworker (Metadata Extractor)', which outputs structured metadata tags ('Title', 'Author', 'Date') into a database box labeled '.Spotlight-V100 Index'. Flat 2D vector illustration, Apple developer documentation aesthetic, white background, clean typography."

Option A (Real UI Screenshot): An MDM (Jamf Pro / Intune) Storage Configuration Profile settings screen showing disk monitoring and exclusion paths for Endpoint Security tools (Antivirus) skipping read-only SSV paths.
Option B (Flat 2D Technical Diagram Prompt): "A clean 2D technical diagram showing Enterprise Endpoint Security scanning strategy. A shield icon labeled 'Enterprise Security Agent' scans only the 'Data Volume (/System/Volumes/Data)' while bypassing the 'Sealed System Volume (SSV)' marked with a green checkmark 'Verified & Immutable'. Minimalist 2D IT diagram, flat style, white background, no sci-fi effects."
