Apple’s software engineers are testing iOS 26.4.1, reports MacRumors. The website says its visitor logs show visits from devices running the still to be released update.
iOS 26.4.1 will likely be a minor update to fix bugs and/or remedy security vulnerabilities. We will likely see a release of the update sometime this week or next.
We may also see a macOS 26.4.1 update and/or a Studio Display XDR firmware update in the near future. When Apple recently launched the new Studio Display XDR, it promised to release a Medical Imaging Calibrator that enables the monitor to display DICOM medical imaging. Apple says the new feature will allow radiologists to view diagnostic images in apps like Visage 7 directly on the Studio Display XDR.
From Apple’s original Studio Display XDR press release:
Today, Apple introduces new DICOM medical imaging presets and the Medical Imaging Calibrator to enable use in diagnostic radiology, allowing radiologists to view diagnostic images directly on Studio Display XDR. Many medical professionals already use Mac for their office or home setups, and Studio Display XDR offers a versatile alternative to single-purpose medical imaging displays, with seamless display mode switching.
The Medical Imaging Calibrator on macOS is pending FDA clearance and is expected to be available soon in the U.S. For decades, healthcare professionals and developers have taken advantage of Apple’s innovative products and frameworks to help achieve better patient outcomes, broaden research opportunities, and improve efficiency across healthcare systems. Apple continues to innovate and collaborate with the healthcare community on solutions to ultimately improve care for their patients.
Earlier today, 9to5Mac reported that the feature has received FDA clearance and is launching this week, so we’ll likely see the updates to enable that feature.
