Exploding Eight Mac Security Myths

Introduction

In 20+ years of supporting Macs in small businesses, we've heard it all - from "Macs don't get viruses" to "No one is interested in a tiny business like mine" to "All my stuff's in the cloud - so I'm good". But in 2026, it's clear these are all just myths and using a Mac instead of a PC isn't a silver bullet for security. But the thing about myths is that if you believe them for too long, and don't evolve your thinking along the way, those out-of-date beliefs could really cost you. Security isn't a 'thing'. It's a collection of choices. Which means there are good security choices and not-so-good choices. We're going to blow up 8 of the more common Mac security myths - so you can start making more informed security choices.

Myth: Apple’s built-in security is enough

Reality:

From Gatekeeper to XProtect to requiring

developers sign and notarize their installers,

Apple goes to great lengths to build security

into macOS. And they do a great job. But it's

not enough. Bad guys are constantly looking

for ways to slip malware onto your Mac. In

March 2023, VoIP software vendor 3CX had

malware slipped into their Mac app. Because

the installer was signed and notarized,

XProtect and Gatekeeper stayed silent. But if

you were using endpoint detection and

response (EDR) software from Jamf or Huntress, among others, you were

covered. This is because EDR tools don't just

look for known malware. They also look for

malicious behaviors so they can protect

against things they haven't even encountered

yet. Proper security requires layers. Think of

Apple's built-in tools as merely the base

layers.

Myth: Running out-of-date version of macOS isn’t a big deal

Reality:

For years, Apple informally said they would only promise security updates for the most current version of macOS. In 2022, Apple made that official. If you're not running the current version of macOS, you may not get the latest security patches. What's more, every time Apple patches security holes they publish the vulnerabilities (called CVEs) they fix. This public disclosure is a good thing - but it also tells the bad guys the things that older versions of macOS are vulnerable to. What's more, cyber insurance carriers are paying attention. Some have started implementing a grace period for patching. If an update is released and not applied within the grace period, the carrier will incrementally reduce the amount of a claim they're willing to pay.

Myth: All our stuff is in the cloud - so we don’t need to worry about security

Reality:

Whether Microsoft, Google, Dropbox, or any other cloud provider, they only secure the infrastructure that houses your data. Think of it like renter’s insurance. Your landlord is responsible for insuring the building, but you are responsible for insuring and securing your data. So all the security measures such as multifactor authentication, backups, intrusion detection & restricting access to data are still necessary.

Myth: We're just a very small business. We don't

have anything bad guys would want.

Reality:

Even if your company's data itself wouldn't entice bad guys, if you work for larger clients that data can be a gold mine. After all, why would a bad guy bang his head against a wall targeting a large (and well-secured) company when he can get what he wants from their smaller vendors who generally haven't invested in cybersecurity? Recently, one of our clients was engaging with a larger, very visible organization who handed them a very detailed cybersecurity questionnaire they required of all vendors. If your organization hasn't yet come across prospective clients expecting you to have your cybersecurity ducks in a row, you will. And as the cliche goes. . .you’re not too small to get hacked. You’re just too small to make the news.

Myth: Our team can take care

of updating

apps on their own

Reality:

It sounds simple enough, right? The little alert pops up, you click it, and the program updates. But in practice, it's never that simple. In 20+ years of supporting humans, we've found people’s first response tends to be clicking whatever makes that pop-up go away the fastest. But unpatched apps are one of the most common ways bad guys exploit systems. Indeed, the LastPass breach of 2022/23 happened in large part because a senior engineer was working from his personal computer and bad guys exploited a vulnerability in an app which had been patched 3 years before. That's right, because this person hadn't kept his apps up to date, bad guys were able to gather critical information to continue their attack on his employer. Systems & processes that deploy app updates AND monitor that apps on company systems are up-to-date are a key part of defending your company from cyber breaches. And in 2026, AI is helping bad find and exploit security holes faster than ever. Allowing users to patch software if/when they get around to it presents serious risks to your business.

Myth: I trust my team to do the right

thing,

so we really don't need cybersecurity

training.

Reality:

Security isn't a thing - it's a collection of choices. Your team is your first - and most important - line of cyber defense. Bad guys work very hard to find new and innovative ways to trick people into making bad cybersecurity choices. Without ongoing cybersecurity training, you're expecting your team to defend your company without any tools against a highly skilled and determined enemy.

Myth: We don't really need a documented process

for

offboarding employees when they leave

Reality:

It's never fun to part with an employee, even if it's on good terms. But if your offboarding 'process' consists only of getting the person's computer back, you're leaving your company open to all kinds of security risks. It's important to monitor what services/accounts an employee has access to so when they leave those accounts can be quickly closed or redirected in a thorough and systematic way.

Too often, we find that long-terminated employees still have server, VPN, email, etc. accounts that are still active. Remember. . .no one is disgruntled - until they're disgruntled. And putting out fires caused by former employees abusing access that wasn't disabled on their departure is the worst way to find out what they're capable of.

Myth: Our Mac fleet doesn't need to be managed

Reality:

Mac management is the collection of systems, tools, & processes that keeps your team productive while implementing the various layers of security. Think of management as the glue that brings everything together. From mobile device management (MDM) to deploy & enforce settings that align with cybersecurity frameworks such as CIS or NIST to keeping operating systems & apps updated to security awareness training to processes that reduce the risks and exposures to your organization. Back in the day, you could designate a member of your team to be your IT person as an additional duty. But the game has changed and the stakes have gone up - a lot. One look at the questions your cyber insurance carrier is asking at renewal time will tell you even for small businesses IT has moved beyond the grasp of a well-meaning hobbyist. You need to manage your Mac fleet like your company depends on it. Because in the cybersecurity landscape of 2026, it does.

Conclusion:

It used to be that you could task a designer or other employee to be your "Mac person". But over the last several years, the increase in cyber threats and risks to your business has made that a less-than-ideal choice. The stakes are just too high to leave your IT to a hobbyist.

Security not a thing, but a collection of choices. We hope by exploding these 8 persistent Mac security myths, you're now better equipped to guide your business toward good cyber security choices.
