EDR for Mac: The Best Endpoint Security Solutions for Apple Devices

EDR for Mac is genuinely necessary in 2026, not an optional extra for a platform that used to fly under the radar. Trojans now make up more than half of all Mac malware detections, and a critical vulnerability disclosed this year shows exactly how an unprotected Mac fleet gets exploited. The old advice to skip antivirus on macOS is actively dangerous now.

Do Macs need EDR? Retiring the myth

Yes. Mac endpoint security genuinely matters in 2026: Jamf Threat Labs found trojans now account for more than half of all Mac malware detections, with one family, Atomic Stealer, responsible for 77% of that trojan category alone as of May 2026.

The “Macs don’t get viruses” belief was never fully true, but it was defensible when Mac market share and attacker interest were both low. That calculation has flipped. macOS malware incidents rose 73% year over year in 2025, and 66% of Mac users encountered at least one cyber threat that same year. A critical vulnerability disclosed in June 2026, covered in detail below, gave attackers a documented way to silently disable enterprise EDR and MDM agents on Mac using nothing more than a standard, non-admin user account, no kernel exploit required. That single finding retires the myth more convincingly than any general reassurance: this isn’t a hypothetical risk, it’s a named, patched, publicly disclosed 2026 vulnerability that specifically targeted the tools businesses already deploy to protect their Mac fleets.

How does EDR work on macOS? The Endpoint Security Framework explained

EDR for Mac relies on Apple’s Endpoint Security Framework, a system-level API that gives authorized security tools visibility into process execution, file system events, and network activity, replacing the older, less stable kernel extension model most EDR vendors used before Apple deprecated kexts.

This framework is why modern Apple EDR products are now “kextless,” running as user-space system extensions rather than kernel extensions, a shift Apple pushed specifically for stability and security reasons. The Endpoint Security Framework feeds real-time telemetry to the EDR agent, process launches, file modifications, network connections, which the agent then analyzes for malicious behavior. This is also precisely the layer targeted by CVE-2026-39118, covered later in this article: an attacker who can disable the Endpoint Security Framework extension feeding an EDR agent effectively blinds that agent without needing to compromise the agent’s detection logic directly.

Trojans and Atomic Stealer: the current numbers behind the threat

Atomic Stealer, also called AMOS, is the dominant Mac-specific malware threat in 2026, tied to 40% of all macOS protection updates Sophos shipped in 2025, with detections spiking 300% in a single month that August. Jamf Threat Labs data from May 2026 puts it at 77% of all trojan detections specifically.

Metric	Figure	Source
Share of Mac trojan detections	77%	Jamf Threat Labs, May 2026
Share of Sophos macOS protection updates	40%	Sophos, 2025
YoY growth in macOS malware incidents	73%	Industry aggregate, 2025

AMOS spreads primarily through social engineering rather than software exploits: fake “macOS toolkit” websites instructing users to paste commands directly into Terminal, disguised cracked-software downloads, and ClickFix-style verification prompts. Once running, it harvests browser credentials, cryptocurrency wallet data, and messenger app content, over half of victims had crypto-related applications installed, making it a financially motivated, credential-focused threat rather than a destructive one. A newer 2026 variant of the distribution method specifically targets developers using AI coding tools, hiding malicious instructions inside fake “skill” files on AI agent marketplaces, showing the threat actively adapting to how Mac users now work.

A real, current vulnerability: how CVE-2026-39118 silently disabled EDR agents

CVE-2026-39118, disclosed by researcher Hillel Pinto of XM Cyber in June 2026, let a standard, non-admin macOS user account silently disable enterprise EDR and MDM agents, no administrator credentials, no kernel exploit, and no alerts triggered.

The attack chain combined three legitimate macOS behaviors: weakly validated XPC connections, malicious payload injection into application interface files, and abuse of the kernel’s code-signing trust cache, which continues trusting an application’s signature after a legitimately signed app has already run. XM Cyber demonstrated the technique successfully against CrowdStrike Falcon Sensor, fully unloading it from a standard account, and against Kandji’s MDM agent, which was permanently deactivated through a two-stage attack that specifically killed the Endpoint Security Framework extension feeding it data. A third, unnamed enterprise EDR vendor was also successfully targeted. Kandji patched the flaw and it was assigned CVE-2026-39118. CrowdStrike added detection and prevention across its supported macOS sensor versions and paid a bug bounty. Apple, notably, stated it does not plan to remediate the underlying macOS design issue, leaving mitigation entirely to security vendors. Because the technique requires only a standard local account, security researchers frame it primarily as an insider or post-compromise threat, meaning an attacker who’s already gained a low-privilege foothold, through phishing or a compromised app, could use this exact chain to blind your EDR before doing anything else. If your organization runs any of the named vendors, confirm your current agent version explicitly addresses this vulnerability, since Apple’s refusal to fix the underlying issue means ongoing vendor-side vigilance is the only real defense.

The Mac-Windows parallel: this is the same story you’ve seen before

The pattern playing out on Mac now, rising trojan volume, a critical agent-disabling vulnerability, growing attacker sophistication, mirrors exactly what Windows environments experienced years earlier, before EDR became a default assumption rather than an optional upgrade. Businesses that treated Windows EDR as non-negotiable years ago are now making the identical mistake of treating Mac as exempt.

This parallel matters because the lesson from Windows already happened: attackers follow install base and perceived defenses, not platform loyalty. As Mac adoption climbed in enterprise environments, particularly among developers and executives, attacker interest followed proportionally, and the CVE-2026-39118 vulnerability shows Mac-specific attack research has reached genuine sophistication, not copy-pasted Windows techniques. Treating Mac EDR as a lesser priority than Windows EDR in a mixed fleet, common in businesses that adopted Mac policies before this threat shift, now represents the exact gap attackers are positioned to exploit first, precisely because it’s the less-defended half of the estate.

Does UK Cyber Essentials require EDR on Mac fleets?

Not strictly, but it’s increasingly the practical choice. Cyber Essentials’ malware protection control requires either anti-malware software meeting specific functional criteria, auto-updating signatures, active blocking, script protection, or application allow-listing, and macOS’s built-in tools can satisfy this when properly configured, though third-party EDR provides stronger evidence for assessors.

Under the current Requirements for IT Infrastructure v3.3, effective from 27 April 2026 with the new Danzell question set, the malware protection control doesn’t name EDR specifically as mandatory. For basic Cyber Essentials certification, correctly configured built-in macOS protections can technically satisfy the requirement. However, for Cyber Essentials Plus, which includes independent technical testing, or for businesses in higher-risk sectors, a third-party EDR solution provides materially better evidence of consistent, verifiable protection, particularly in mixed Mac and Windows environments where a unified EDR console gives assessors clear, consistent proof across the entire estate. Separately, v3.3’s stricter 14-day patching auto-fail and mandatory MFA on all cloud services apply equally to Mac devices in scope, meaning even businesses relying on built-in malware protection alone still need functioning patch management and MFA enforcement across their Mac fleet to pass. Cyber Security Solutions Ltd advises UK clients pursuing Cyber Essentials Plus specifically to budget for third-party EDR on Mac devices from the outset, since the assessor evidence gap between built-in tools and a dedicated EDR platform becomes the most common reason for a failed first attempt.

The performance trade-off: what running EDR on macOS costs you

Modern Mac EDR platforms are now kextless and Apple Silicon native, a real improvement from three years ago, meaning the performance cost is smaller than it once was but not zero, expect some measurable CPU and battery impact, particularly during active scanning or large file operations.

The performance trade-off varies by platform architecture rather than being uniform across vendors, agents with heavier real-time behavioral analysis generally carry a higher baseline resource cost than those relying more on cloud-based detection. For most business use cases, well-configured modern EDR on Apple Silicon Macs runs with an impact most users won’t consciously notice during normal work. The cost becomes more visible on older Intel-based Mac fleets still in use, or during resource-intensive tasks like video editing or large compiles, where background scanning can create noticeable slowdown. Test any EDR platform against your actual heaviest-use workflows before full fleet deployment, not just a light productivity benchmark, since the gap between vendors shows up most clearly under real load.

What about Linux? A complementary look

EDR for Linux deserves brief mention alongside Mac coverage, since businesses running mixed development environments often have both platforms in scope together. Linux EDR trails Mac and Windows in vendor maturity and out-of-box coverage, making manual hardening and careful agent selection more important than on the other two platforms.

Linux environments, common in DevOps and backend infrastructure, frequently run without any EDR at all, treated as “server infrastructure” rather than an endpoint needing the same protection philosophy as a laptop. This is a genuine gap, since Linux systems increasingly hold the same sensitive credentials and access as any other endpoint. If your business runs a mixed Mac, Windows, and Linux environment, confirm your chosen EDR platform genuinely covers all three natively rather than treating Linux support as an afterthought bolted onto a Windows-first product.

Does supply chain risk reach Mac developers too?

Yes, directly. The Shai-Hulud npm worm campaign compromised thousands of npm packages that Mac-based developers pull into projects every day, showing that Mac developers face the same software supply chain exposure as any other platform, regardless of how well their own endpoint is protected.

This matters because EDR on the developer’s own Mac doesn’t inherently protect against a compromised dependency pulled in through a package manager, the malicious code executes with the developer’s own legitimate permissions, exactly the kind of activity a well-tuned EDR agent should flag as anomalous but that traditional antivirus signature matching would miss entirely. A Mac-based development team running solid EDR still needs separate supply chain hygiene: dependency scanning, lockfile verification, and caution around auto-updating packages, since the malware in a compromised npm package looks like normal build activity from the endpoint’s perspective until it starts exfiltrating data or credentials. Treat supply chain risk as a distinct layer requiring its own controls, not something EDR alone resolves for a Mac-based development team.

Conclusion

EDR for Mac has moved from optional to essential, driven by real 2026 evidence: rising trojan volume, a documented vulnerability that silently disables agent protection, and supply chain risk that reaches Mac developers directly. Choose a platform that fits your existing device management stack, and confirm it addresses CVE-2026-39118 specifically before you deploy.
