Apple briefly exposed iPadOS 27 beta restore images for two older iPad Pro models that aren't officially supported, then quickly removed them from developer downloads. The company's developer site initially included files for 11-inch iPad Pro (1st and 2nd generations) and 12.9-inch iPad Pro (3rd and 4th generations), despite these models being absent from the official compatibility list.

The file names themselves referenced these unsupported iPad Pro models, suggesting this was more than a simple display error. When 9to5Mac attempted to install the IPSW on a 3rd-generation 12.9-inch iPad Pro, the installation failed outright. Apple has not commented on whether this represented an incomplete compatibility list or a straightforward oversight.

This incident differs from recent watchOS 27 confusion involving Apple Watch Series 9, where users successfully installed the beta. Apple's swift removal of the restore links while maintaining the official compatibility list suggests the older iPad Pro models genuinely lack the hardware requirements for iPadOS 27. The episode highlights how Apple's beta distribution process can briefly expose unfinished compatibility decisions.
