what is Rosetta? Apple devices

Rosetta automatically translates applications designed for Intel's X86 processor when installed


You may have heard about the name Rosetta when Apple first announced it in 2006 while switching from PowerPC processors and moving to Intel processors, and then about Rosetta 2 at the Developers Conference 2020, when announcing the transition to Apple processors, what is this hidden program that works in the background and why it was said to be the secret of Apple’s success and that it


Rashid’s stone

Many do not know that the name Rosetta is Rashid, an Egyptian coastal city and symbolizes the Rosetta Stone, a cerection of ganodial stone with a decree issued in Memphis, Egypt, in 196 BC on behalf of King Ptolemy V.

The decree shows three texts: the upper text is the ancient Egyptian hieroglyphic Egyptian language, the middle part is the hieratic text, and the lower part is ancient Greek. Because it essentially presents the same text in all three texts, the stone gives the key to a modern understanding of Egyptian hieroglyphics.

The Rosetta Stone was revealed in 1799; the stone that included the key to the ancient Egyptian language without which Egyptian civilization would have remained mysterious and we do not know about it, because we cannot read the writings written by the ancient Egyptians on their monuments.

Rosetta is the secret of Apple’s success

The transition of companies from one processor to another often leads to a major failure, and this is what happened with Microsoft before when it tried to adopt ARM processors in their devices.

Microsoft has tried more than once to use ARM processors in mobile computers, the latest of which is Surface Pro X devices, but although the devices run Microsoft programs designed specifically for them splendor, they are unable to run important programs such as Chrome, Photoshop and other programs designed for x86 processors in a way that justifies the purchase, especially with the high price of the device.

But the situation is different with Apple, which has been able to successfully change the processor and move smoothly not once but more than once from one processor to another in a short period of time and without losing sales, and the reason and secret to success is this hidden program Rosetta.

How does Rosetta work?

Rosetta automatically translates applications designed for Intel’s X86 processor when installed, not during operation, and this increases the running speed of the application due to the lack of overload on the device’s processor.

Rosetta works in the background and the user doesn’t know anything about it other than that it opens the app and finds it working efficiently as if it’s working on the processor designed for it.

This is the secret to the success of new Apple devices with M1 processors and the efficiency and speed of applications working on them, even if they are not designed for these devices.


Rosetta program will end soon

Rosetta is designed to help with the transition between Intel processors and Apple processors, and Apple is expected to delete Rosetta at the end of 2023 after the entire transition is over and most of the app is compatible with new Apple processors, and here there is no actual need for Rosetta.

The transition seems to be running very smoothly, as most large companies have already switched their popular apps to Apple processors
