An Australian court has fined Apple A$9m (£5m;$6.5m) for refusing to fix iPhones and iPads that had been serviced by third parties.
The nation's consumer watchdog took the tech giant to court last year following complaints from users about faulty devices.
Apple admitted that it misled 275 people about their rights to remedies such as repairs and replacements.
The Federal Court of Australia found those actions breached consumer law.
The investigation followed complaints about Apple's so-called "error 53".
The fault rendered iPhones and iPads inoperable, after users downloaded a software update.
But when customers sought repairs, Apple denied some of them assistance because their devices had previously been fixed by a third party, the Australian Competition and Consumer Commission (ACCC) said.
