Known Issue: DLP Endpoint Printing Protection
Functionality Impacted on Specific macOS versions
Dear customer,
Trellix is committed to providing timely support for new macOS releases. However, recent security changes Apple introduced in macOS 27 (Golden Gate), macOS 26.7.1 (Tahoe), and macOS 15.8.1 (Sequoia) have affected Printer Protection functionality in Trellix Data Loss Prevention (DLP) Endpoint Complete.
This means that for supported agent versions (including 11.11 and 11.13), Printer Protection rules are currently inactive on devices running these macOS versions. Other core DLP features remain functional. We advise customers who rely on print security to review the recommended actions below.
What your users will experience
- On endpoints running macOS Golden Gate, Tahoe, or Sequoia, print activity will not be intercepted or inspected.
- Rules configured to block, monitor, or alert on print jobs will not trigger.
Trellix resolution plan
We are actively working to resolve this issue and are offering a fix in two ways to accommodate your organization's deployment preferences:
-
Path 1: Request-Only Hotfix (Version 11.13)
- We are developing a hotfix for deployment as soon as possible to restore printer protection support for Golden Gate, Tahoe, and Sequoia.
- Customers on our current version (11.13) can submit a technical support ticket to request the hotfix. We will share the fix with you as soon as it becomes available.
-
Path 2: Generally Available (GA) Update (All Versions)
- All customers on supported versions can plan to upgrade when the upcoming 11.13.2 release launches. This update is targeted for early to mid-November and will include the built-in fix across all versions alongside several new product enhancements.
If you are currently on DLP Endpoint Complete for macOS 11.11.x and do not plan to upgrade, hotfix requests will be considered. Please submit a support ticket if you would like to request Printer Protection on 11.11.x.
