Model identifiers for three unannounced Macs have recently made their way into a configuration file on the Find My’s network backend. Developer Nicolás Álvarez first observed the discovery, sharing his findings on Twitter.

The new identifiers in question are “Mac14,8”, “Mac14,13”, and “Mac14,14”. They join “Mac14,3” and “Mac14,12” identifiers for M2 and M2 Pro Mac mini models, respectively. Álvarez notes that the configuration file overrides the Find My’s Notify When Left Behind feature. This suggests that the identifiers belong to desktop Macs, as they won’t notify the user of being left behind when they are no longer in the desktops’ vicinity.

All M2-based Macs have identifiers in the form of “Mac14,x”. This suggests that the identifiers at hand could possibly belong to a desktop Mac powered by a variant of the M2 chip.

Mac Pro with the M2 Ultra chip is expected sometime this year, while the Mac Studio and the iMac are set to skip out on the M2 series entirely. Two Mac Studio models are in early development and could be announced in 2024, and a refreshed iMac with the M3 chip could debut in the second half of 2023.

Bloomberg recently discovered a Mac laptop going by the identifier “Mac15,3” in App Store developer logs. The machine is said to be powered by a chip “on par” with the M2, although it doesn’t follow the trend of “Mac14,x” identifiers for M2-based Macs.

Perhaps one of the identifiers is the allegedly-scrapped M2 “Extreme” variant of the Mac Pro, and Apple is simply yet to remove all mentions of the canceled configuration. A single product can have multiple identifiers if powered by multiple chips. For example, the Mac Studio is identified as “Mac13,1” for the M1 Max configuration and “Mac13,2” for the M1 Ultra.
