Downloader differs from previously opened versions

[zorgiepoo]

Due to a sandboxing issue new to macOS Sonoma and due to this app and other apps using Sparkle's Downloader XPC Service, users may see a one-time system warning dialog when checking for updates about "Downloader" differs from previously opened versions.

It looks like Tinkle wants to use the Sparkle's Downloader XPC Service from following Sparkle's sandboxing guide because the app is not entitled with an outgoing network connection (com.apple.security.network.client) entitlement. So there are a couple ways to fix this issue:

• Tinkle can update to Sparkle 2.6.0 or later (which disables sandboxing for the Downloader XPC Service by default to avoid conflicts) (easiest way)
• Tinkle can re-compile their current version of Sparkle with a custom XPC_SERVICE_BUNDLE_ID_PREFIX

See sparkle-project/Sparkle#2514 for more information on the issue.
