People who play Fortnite on Apple Macs, iPhones and iPads are to be ecluded from the game’s latest update.
This follows the weeks-long escalating row between the two companies, which resulted in Fortnite being pulled from Apple’s App Store.
Mac computers, which do not use the Apple store, are also now affected.
Fortnite’s updates often make sweeping changes to the game and Thursday’s introduces a partnership with Marvel comics superheroes, among other things.
Epic Games chief executive Tim Sweeney blamed Apple’s plan to pull access to developer tools on 28 August, the day after the new season begins.
“Apple has said they will revoke all of Epic’s Apple SDK [software development kit] access for game development on Friday,” he said.
“If they do that, we won’t be able to update Fortnite on Mac.”
Current versions of the Mac operating system try to stop users opening any apps not checked by Apple, using a process called “notarising”.
