Engadget Logo Engajet Japanese M1 chip Mac, "Universal" and "Rosetta 2" expand the range of operating apps

At the same time as the 3 models with M1 chips developed by Apple, the next MacOS "BIG SUR" will be released on November 13.These two are closely related to Apple that "MacOS Big Sur was developed to release the M1 chip's abilities" (Big SU also eligible for existing Mac models with Intel chips.)

What is worrisome is the company's appeal, "Collection of the largest app so far", that is, the width of the corresponding app.If the category is roughly divided, one app is made exclusively for M1 chips.The existing Intel chip -equipped Mac app can be used as it is with "Rosetta 2", and it is said that the iPhone/iPad app can be used on MacOS for the first time.

In addition, "All Mac software made by Apple will be universal applications and can be moved natively with the M1 system."There have been some unfamiliar concepts for Mac users in recent years, but in fact Apple explained WWDC20 and later.Below, let's review them in step.

First, a universal application is one app, including Intel chips and M1 chips (one type of Apple Silicon), both native codes.This is the return of "UNIVERSAL", which was once provided when the Mac was transferred from PowerPC (PPC) to Intel processor, which is a new assortment of Intel and M1 binary.

In short, since the "separate code is set for two tips", it works on either the new and old Mac regardless of the compatibility of the hardware, but the file size of the application is larger, and the download time is large.It seems to be extra.By the way, it has been pointed out that a universal app that supports PPC, Intel and Apple Silicon 3 generations can be created (whether it's practical).

Next, Rosetta 2 is the "Rosetta" again provided by the PPC when the Intel chip is transferred.This time, the binaries for Intel will be converted to binaries for Apple Silicon as appropriate.

There is a concern that the performance will decrease because the load will be applied to the CPU in real time.At the beginning of the DTK DTK for Apple Silicon migration, it was estimated to decline by about 25 to 40%, but as the nominal of Apple, the CPU performance and graphics performance of the M1 chip have been increased several times.If so, the speed of the app may be higher.

In addition, the third iPhone/iPad app is all operated on the Apple Silicon Mac, but major app developers such as Google have opt -out on the MacApp Store, which also uses many game apps.There were rumors that I could not do it.

Up to this point, "Apple is saying", but what is worrisome is "not touching".Specifically, it is a Boot Camp that can be fatally important depending on the user's application (a function that allows you to install Windows 10 on a Mac and switch between MacOS and Windows when booting).Apple did not mention anything at the One More Thing event on the 11th.

Regarding the virtual machine app that realizes the same function as the Boot Camp, Rosetta 2 above is "virtual machine application that virtualized the X86_64 computer platform does not work", that is, Parallels and VMware, at least in the current version.It is clear that it cannot be done.

Can Rosetta 2 really move all existing Intel MacOS apps or access many iPhone/iPad apps on the MacApp Store?Also, whether BootCamp will be provided in the future in the M1 chip + BIG SUR (it is unknown whether Microsoft will provide ARM Windows 10 licenses to the general users even if it is technically cleared).I want to wait.
