Calcutta II

Calcutta II’s Gatekeeper Tango on Sonoma

Downloaded Calcutta II ( last week to streamline my office docs — it’s a compact productivity tool for merging spreadsheets and quick reports. On my M3 MacBook Pro with macOS Sonoma 14.5, though, it hit the wall hard: wouldn’t launch, spitting out “Calcutta II.app is damaged and can’t be opened” every time. macOS’s security paranoia strikes again.

Early Misses

Standard first aid: right‑click Open, confirm the dialog. Dock icon flickered, app vanished. No crash log, just quiet failure.

Went nuclear — System Settings > Privacy & Security, hunted for “Allow Anyway.” Clicked, relaunched. Same nonsense. Terminal check via xattr -cr on the bundle? Zilch. Activity Monitor showed it dying in under a second with a SIGKILL from sandboxd.

Suspected a notarization mismatch, common for productivity suites from smaller devs. That’s when this page caught my eye — it described identical Sonoma blocks on unsigned builds, nudging me toward entitlements.

What Cracked It

Clue from Console: tccd[123]: Refusing to authorize action for client — permission hell. Sonoma’s TCC (Transparency, Consent, and Control) was clamping down on plist reads for the tool’s report generator.

Step one: quarantine purge at source.

xattr -dr com.apple.quarantine ~/Downloads/"Calcutta II.app"

Moved to Applications. Still blocked. Then the key: System Settings > Privacy & Security > Files and Folders > toggled access for Documents and Spreadsheets (it listed them separately). Relaunch worked.

Verified safety with codesign --verify --deep --strict /Applications/Calcutta\ II.app — “accepted source.” Apple’s unidentified developer guide covers the basics, while their notarization docs explain why TCC rejects unsigned access requests. No App Store hit on apps.apple.com search, so indie all the way.

Post‑Fix Reality

Calcutta II hummed along after that — merged 50 CSV files into a report in seconds, no iCloud sync hiccups once I added Full Disk Access. Minor lag on large folders vanished after a metadata rebuild: mdutil -E ~.

My go‑to fixes boiled down to:

Purge quarantine pre‑install.

Explicit Files/Folders permissions.

Codesign check.

TCC nudge for Documents.

Now it’s pinned and reliable. Sonoma treats apps like suspects until proven innocent — Calcutta II just needed the right alibi. Ironic how a simple merger caused such drama.
