Overview We are investigating repeated "login" Keychain prompts affecting our macOS application on macOS 26.6.x. The issue appears after upgrading an existing installation. A clean uninstall/reinstall of the same version resolves it. Changing the affected Keychain item's Access Control from "Confirm before allowing access" to explicitly allowing our application/process also stops the prompts. On one affected machine, Apple Support observed a securityd crash followed by: SecKeyCreateSignature failed CSSMERR_DL_INVALID_DB_HANDLE Our code uses some legacy SecKeychain* APIs, so we are currently investigating whether this is related. Questions Were there any changes in macOS 26.6.x around securityd, Keychain ACL handling, or legacy SecKeychain* APIs that could explain this? Could an existing Keychain ACL become stale after an application upgrade, even when both versions are signed with the same Developer ID?

I have an app that acts as an agent (no dock/app, just menu bar icon). When the icon is clicked, I show a popover with a small user interface. This works great, however, there is an issue. When a certain app is in full-screen and then my menu bar icon is clicked, the user interface shows just fine, until the mouse is moved outside the menu bar - then the user interface stays but the menu bar dismisses and closes. Is there a way to keep the menu bar open, like when clicking on Control Center, in full-screen apps? This is how I open my popover: if let button = statusItem.button { if popover.isShown { self.popover.performClose(sender) } else { popover.show(relativeTo: button.bounds, of: button, preferredEdge: .minY) popover.contentViewController?.view.window?.makeKey() } } }

My macOS app includes a system extension that is activated once the app is ran. The system extension requires Full Disk Access. When navigating to System Settings → Privacy & Security -> Full Disk Access, I can see my extension listed, but it has the default system "lego" icon, instead of my app's icon. My app icon is working fine everywhere else. I tried to add an Asset Catalog to my extension on Xcode and include the icon, but it didn't do anything. Is this the default behavior for extensions, or can you include an icon?
