McDonald’s Happy Meals are once again bringing smiles, following the resolution of technical issues.

McDonald’s restaurants across Australia have resumed operations after experiencing closures due to a global technology failure.

The incident on Friday resulted in some staff being sent home, with numerous reports to Downdetector regarding difficulties accessing the McDonald’s app, check-out, and website. A statement posted by “Team Macca’s” in the early hours of Saturday confirmed the resolution of the technology outage.

“All Macca’s restaurants have now re-opened,” the post on X (formerly Twitter) announced. “A huge thanks again to our wonderful customers and hard-working crew for your patience and support.”

The issue commenced around 4 pm and impacted various countries worldwide, including the UK, New Zealand, Hong Kong, Japan, Denmark, Italy, and Thailand.

McDonald’s, headquartered in Chicago, attributed the outage to a third-party technology provider and assured customers that it was not a cybersecurity issue.

Across the country and overseas, McDonald’s operations were disrupted as the Golden Arches encountered an IT glitch, putting Big Mac orders on hold.

Friday’s takeaway plans were disrupted for customers, with some stores shuttered entirely and others only accepting cash orders. In an updated statement shortly after 9 pm (AEST), a spokesperson acknowledged the “technology outage” affecting restaurants and assured customers that the company was working to resolve the issue.

“We thank customers for their patience and apologize for any inconvenience this may have caused,” the spokesperson told 7NEWS.com.au.

Signs posted at store entrances informed customers of the situation, with one indicating, “We cannot take any orders. Our systems are down — this is a national issue (at the moment). Sorry for the inconvenience.” Another store in Perth informed customers that only cash orders were being accepted.
