macOS 27 Beta: Multiple system services repeatedly crashing — unable to use Mac normally

Hi everyone,

I’m currently running macOS 27.0 beta (26A5388g) on my Mac, along with the latest Xcode 27 beta, and I’ve recently started experiencing a serious issue where multiple macOS system services are repeatedly crashing.

Initially, I started getting repeated “intelligencetasksd quit unexpectedly” notifications. At first it happened occasionally, but it has now become extremely frequent.

After dismissing one crash notification, another system service often crashes shortly afterward. I’ve also seen services related to Intelligence / intents crashing. The notifications keep appearing one after another to the point where I’m barely able to use the Mac normally — including difficulty typing and interacting with applications.

The issue is not limited to Xcode. It appears to affect macOS system services themselves.

System information

  • Mac: Mac15,2 (Apple silicon)
  • macOS: macOS 27.0 beta, build 26A5388g
  • Xcode: Xcode 27 beta
  • Issue started: After running the macOS beta for some time; it has progressively become more frequent
  • Main process initially crashing: intelligencetasksd
  • Path shown in crash report: IntelligenceTasksEngine.framework/Support/intelligencetasksd
  • Exception: EXC_BREAKPOINT (SIGTRAP)

I have attached a screenshot of the crash report showing the intelligencetasksd crash.

Has anyone else experienced this on macOS 27 beta? Is there a known issue with the new Intelligence/Intents services, or is there a recommended way to reset/rebuild the relevant system components?

At this point the repeated crashes are making the Mac extremely difficult to use, so I’d really appreciate any troubleshooting steps or information about whether this is a known beta issue.

Thanks!

I’ve been seeing similar repeated crashes when opening, closing, or simply running Simulator since using the earlier betas and continuing even now with stable releases.

Environment: Apple-silicon Mac (Mac17,9), macOS 27.0.1 (26A434), Xcode 27 / iOS 27 simulator runtime.

Crashing services:

  • intelligencetasksd
  • AppIntentsLiveEntityService
  • SettingsSearchReindexService
  • others

All three are simulator processes (launchd_sim parent) and crash with EXC_BREAKPOINT / SIGTRAP, following the same stack:

XPCPeerRequirement.hasEntitlement(_:)
→ __XPC_API_MISUSE__
→ __XPC_INTERNAL_CRASH__
→ _assertionFailure

Reboots, Xcode updates, reinstalling the simulator runtime, creating fresh simulators, and clearing simulator caches/DerivedData haven’t resolved it.

Has anyone identified a cause or workaround for this stuff?
