Apple appears to be testing a forthcoming iOS 26.6.1 update for iPhone users. This comes nearly two weeks after iOS 26.6 was released to the public.

iOS 26.6.1 in testing

iOS 26.6.1 started appearing in visitor logs for 9to5Mac this week. This means that devices running the update inside Apple have visited the site. MacRumors has also spotted evidence of the update in their visitor logs.

Apple released a trio of Mac updates this week to address a major vulnerability impacting the Screen Sharing app. This included macOS Sonoma 14.8.9, macOS Sequoia 15.7.9, and macOS Tahoe 26.6.1.

It’s worth noting that not every update Apple tests internally ends up being released to the public, even if it shows up in web analytics logs.
