QuotaKit Mac 0.32.4.7

Fixed

• Mac updates: prevent launch and background refresh from showing Keychain
  permission prompts after an app update.
• Keychain migration: update existing credential accessibility in place without
  reading secret values or deleting/re-adding items, and retry safely later when
  macOS reports that interaction would be required.
• Claude OAuth: limit promptable Keychain reads to explicit user actions such as
  opening the menu or running a manual refresh.
