Latest Message<\/th>\nTitle: Some users may see black screen crashes for MacOS devices configured using Microsoft Defender for Endpoint.<\/p>\n

User impact: Users may see black screen crashes for MacOS devices configured using Microsoft Defender for Endpoint.<\/p>\n

Current status: We received reports from some users where they see black screen crashes on MacOS devices. We’ve determined that a recent Microsoft Defender for Endpoint service update to improve performance contains a code regression which is resulting in crashes for MacOS devices or devices being unable to wake from deep sleep without a reboot. We’re rolling back the offending update and we aim to provide a timeline to mitigation as one becomes available. Once we’ve rolled back the offending update, no additional actions will need to be taken by affected users.<\/p>\n

Scope of impact: Some users may see black screen crashes for MacOS devices if their MacOS devices were updated after September 29, 2025.<\/p>\n

Start time: Monday, September 29, 2025, at 8:00 PM UTC<\/p>\n

Root cause: A recent Microsoft Defender for Endpoint service update to improve performance introduced a code regression which resulted in black screen crashes for MacOS devices.<\/p>\n
