The browser takes 663MB, or specifically the tab?


The Claude tab, itself. From Activity Monitor:

640.6 MB https://claude.ai

51.5 MB Claude

28.8 MB Claude Web Content

20.9 MB Open and Save Panel Service (Claude)

17.5 MB Claude Graphics and Media

15.5 MB Claude Networking

5.6 MB com.apple.Safari.SandboxBroker (Claude)

5.1 MB QuickLookUIService (Open and Save Panel Service (Claude))

---

If I open Claude in Safari, Safari itself is 204MB, and the Claude tab is 640MB.


Those numbers don’t add up to 640mb. If you have 10 Claude tabs open, you’re not using 6gigs of resident memory.
