Do the iPhone XS and XS Max Support iOS 27?
No. The iPhone XS and XS Max are not compatible with iOS 27, and there is no beta available. iOS 26 is the final version this hardware supports, and it is where the iPhone XS and XS Max stop.
The iPhone XS and XS Max stop at iOS 26. They shipped with iOS 12 and received eight major upgrades, which is the same run the XR got and longer than most phones on any platform.
Why the iPhone XS and XS Max Were Dropped
The iPhone XS and XS Max run the A12 Bionic with 4 GB of memory. iOS 27 sets its floor above that, largely because of the on-device machine-learning work the system now does by default.
Apple enforces the cut in the installer itself, checked against the device model rather than against anything you can change. No iOS 27 beta exists for the XS or XS Max. The A12 is below the iOS 27 minimum, and the restriction cannot be bypassed by any file, profile or restore image.
Is There a Beta Profile or Workaround?
No. Beta profiles stopped existing in 2023 — Apple replaced the whole .mobileconfig mechanism with Apple Account enrolment — and even in the profile era, a profile only ever revealed betas your device already qualified for. It never unlocked an unsupported model.
Any site advertising "iPhone XS and XS Max iOS 27 beta profile" downloads is offering files that cannot work. There is no restore image, no configuration file and no setting that installs iOS 27 on this hardware.
What to Run on the iPhone XS and XS Max Instead
Stay on the newest iOS 26 build. It continues to receive security patches, and it is the fastest software these phones will ever run. You will find it under Settings → General → Software Update — take whatever iOS 26 build is offered there and let it be the last major upgrade this hardware takes.
Apple keeps releasing security patches for a release line after it stops receiving features, so staying current on iOS 26 is a supported position rather than a dead end. Our supported devices page tracks where every model stands.
iPhone XS and XS Max Specifications
The iPhone XS and XS Max launched in 2018 with the A12 Bionic, 4 GB of memory and a 5.8-inch and 6.5-inch Super Retina OLED display, in 64 GB, 256 GB, 512 GB storage configurations. They shipped with iOS 12 and finish on iOS 26.
That is a long support life by any standard — most devices on any platform receive nothing like it. The upgrade road ending is not a fault in the device; it is the point where the software outgrew the silicon.
Running an Apple Beta on Another Device
If you want to test iOS 27, you need hardware on the compatibility list. Enrolment is free for everyone now: sign in at beta.apple.com, then choose the beta channel under Settings → General → Software Update → Beta Updates on a supported device.
Our iOS 27 install guide covers the process, and the full compatibility list shows exactly which models qualify this year.

No. Beta profiles no longer exist, and even when they did they never unlocked unsupported hardware. Any file advertised as one is fake.
What is the last version the iPhone XS and XS Max support?
iOS 26. It continues to receive security updates while it remains in Apple's maintenance window.
