==== Enhancements
* Improves the reliability of macOS system extension management in {elastic-defend}.

[discrete]
[[bug-fixes-8.19.24]]
==== Fixes
* Fixes an issue where prebuilt rules were flagged as customized, and showed non-solvable `required_fields` upgrade conflicts, even though you hadn't edited the field. Also improves the performance of the rule edit form and the upgrade flyout for rules with long `required_fields` lists ({kibana-pull}294946[#294946]).
* Fixes the `get-file` response action so {elastic-defend} no longer fails the action as host unreachable when a TLS handshake fails due to a broken connection.
* Fixes a startup crash on macOS that occurred when {elastic-defend} could not determine the OS version.
* Fixes an issue where {elastic-defend} could negotiate a different TLS cipher suite than configured, or reject a valid one, when `ssl.cipher_suites` used the Beats-style names `ECDHE-RSA-AES-128-CBC-SHA256`, `RSA-AES-128-CBC-SHA256`, or `ECDHE-RSA-AES-256-CBC-SHA`.
* Improves {elastic-defend} memory threat protection on macOS 27.
* Updates the {elastic-defend} `get-file` response action to return a symbolic link as a regular file with the content of the file the link points to, and on Linux and macOS with that file's permissions.
* Fixes caseless comparison in {elastic-defend} so it ignores case for non-ASCII letters, such as Cyrillic, Greek, or accented Latin.
