Apple has tested an M3 Ultra MacBook Pro, iOS 18 -leak claims

According to an iOS -18 code -Bleck, Apple tested an M3 -Ultra variant of the MacBook Pro.

Details of an unpublished MacBook Pro configuration have appeared in Chinese social media, which indicates that Apple may have evaluated a version with the M3 Ultra Chip.

The current 14-inch MacBook Pro and the 16-inch MacBook Pro are available with the M4 chips from Apple, including M4, M4 Pro and M4 Max. The same applies to your colleagues in the M3 series, but a new leak suggests that it may have planned a fourth configuration.

On Friday, a contribution described on the Chinese website bilibili some scrapped iPhone, iPad and Mac configurations. The author of the post lists observations that were derived from the operating system of a pre -production prototype of the iPhone 16.

Such devices can and often contain references to unpublished hardware.

Among other things, the leak claims that the early code of iOS 18 refers to two unpublished MacBook Pro variants – J514D and J516D. In view of the fact that the M3 Pro- and M3 Max versions of the MacBook Pro have the device identifiers J514M and J516C, the existence of an M3 -Ultra variant appears plausible.

The tasty realizes that Apple's high-end-end-mac configurations use the “D” suffix to display the use of an “Ultra” phip. The M3 Ultra Mac Studio is known as J575D, for example, while the somewhat weaker M4 Max variant uses the identification J575C.

The M3 Ultra is currently one of Apple's most powerful chips. The system-on-chip supports up to 512 GB of uniform memory and can be configured with a 32-core CPU and an impressive 80-core GPU.

The Mac Studio is a desktop computer with a relatively massive heat sink and a fan. A MacBook Pro with the same chip would probably be exposed to heat or power consumption problems, similar to the late Intel models.

On Friday, Leak realizes that Apple gave up its plans for a PowerBook G5 more than 20 years ago due to similar problems.

We could not authenticate the strings in the software. It may have been limited to some places and there is always the possibility that it was fake.

Internal usage operating system variants for development devices usually include tests and files for several hardware variants, including development boards and experimental devices as well as FPGAS.

Early builds from iOS 4, for example, contained references to an unpublished iPhone with the device detection N89, while internal distributions of iOS contained 8 files that refer to a scrapped iPad Pro with the A8x chip from Apple called J98 and J99.

On Fridays Leck mentions this specific scrapped iPad configuration and describes exactly the inscriptions on prototype hardware. It also lists well-known versions of Apple's internal usage software, in particular the Purplerestore 3 tools used to install operating system distributions. This gives the tasty, which is otherwise not a fixed track record.
