Why Apple doesn't suffer outages like this

An IT meltdown halted airlines, hospitals, and public transport. Here's why Apple devices remained operational during the global outage.

• Windows devices suffered a global outage, but Mac and Linux remain unaffected, CrowdStrike said.
• The issue, caused by a defective update, halted airlines, hospitals, and public transport.
• But Apple's ecosystem control and limited third-party exposure shielded its devices from the defect.

While Windows users suffered from a global IT outage, Mac owners weren't affected by the defect responsible.

Major airlines, banks, and retailers are experiencing widespread disruptions linked to the outage after Microsoft reported problems with its online services, linked to an issue at cybersecurity firm CrowdStrike.

Many businesses have been held up by the "blue screen of death" on their Microsoft devices since early Friday morning, but it's business as usual for Mac users, according to CrowdStrike CEO George Kurtz.

One reason Apple's 2.2 billion iOS devices are exempt from this cybersecurity snafu is the "benefit of an Apple ecosystem," according to Wedbush Securities analyst Dan Ives.

"Everything is controlled within the four walls of Apple Park," Ives told CNBC.

Apple and Windows have different operating systems. iPhones, Macs, and all other Apple products are tightly controlled by the company regarding security and updates. For Windows, updates are more frequent, and its software library is larger than that of Apple's ecosystem. Linux also has its own operating system and was not affected, Kurtz said in his statement on X.

And unlike Microsoft, Apple is less likely to work with third parties — like CrowdStrike — which leaves it "much less exposed on the enterprise," according to Wedbush's Ives.

Apple didn't immediately respond to a request for comment from Business Insider.

CrowdStrike said the issue was caused by a defective update, not a cyberattack; "The issue has been identified, isolated, and a fix has been deployed," Kurtz said. "We refer customers to the support portal for the latest updates and will continue to provide complete and continuous updates on our website."
