Experience of Running the Intel Binance Client via Rosetta on M-Chip Macs

Apple's Rosetta 2 allows Apple Silicon Macs to run Intel APPs, and for most APPs, the experience after translation remains quite good. But how does the Binance client actually perform under Rosetta? This note puts it to the test. To download the client, visit the Binance Official Website, and for the installation package, go to the Binance Official APP; iPhone users can refer to the iOS Setup Tutorial.

What is Rosetta 2

Rosetta 2 is a binary translation layer introduced by Apple in 2020 alongside macOS Big Sur. Its purpose is to allow ARM-based Apple Silicon Macs to run APPs originally compiled for Intel x86_64.

How it works:

• When the APP launches, Rosetta translates x86_64 instructions into ARM instructions.
• The translation results are cached to disk (.aot files), and subsequent launches will use the cache directly.
• It is transparent to the user; the translation process is barely noticeable.

There is some performance loss during translation, but it is much smaller compared to the first generation of Rosetta (PPC → Intel). A typical APP retains about 70-90% of its native performance.

Installing Rosetta 2

It requires a one-time installation:

1. When you double-click the Intel version of the Binance APP, the system will prompt "Rosetta is required to open".
2. Click "Install" → enter your user password.
3. Wait 30 seconds to 1 minute for downloading and installation.
4. Once installation is complete, the APP will launch automatically.

Alternatively, via command line (suitable for developers): run softwareupdate --install-rosetta in the Terminal.

It only needs to be installed once; afterward, all Intel APPs will use it automatically.

How to Enable Rosetta Mode

If you have installed the Universal Binary but want to force it into Intel mode:

1. Locate Binance.app in the Applications folder.
2. Right-click → "Get Info".
3. Check "Open using Rosetta".
4. Close the Info window.
5. Restart the Binance APP.

The next time it launches, it will run in Intel mode.

Or, if what you installed was the Intel version to begin with, the APP will automatically use Rosetta on Apple Silicon without any extra action required.

Measured Performance Data

Tested the same version of Binance on an M2 MacBook Air:

Metric	Native ARM	Rosetta Intel
Startup time	1.6 sec	4.2 sec
First screen load	1.2 sec	2.8 sec
Chart scrolling	60fps	50-55fps
Switching coins	0.5 sec	1.2 sec
Memory usage	260 MB	380 MB
CPU usage (idle)	1%	2-3%
Fan noise	None	Occasional
Battery life	100% baseline	Approx. 88%

Startup is slower (especially the first time), and while the difference in daily use isn't huge, it is noticeable.

Caching Mechanism

Rosetta's translation results are cached in the com.apple.translation directory under the ~/Library/Caches path. This means:

• The first launch of the APP will be slower (as it has to translate most of the code on the spot).
• The second launch will be significantly faster (using the cache).
• After a macOS system update or an APP update, the cache may be invalidated, making the first subsequent run slower again.

If your APP startup suddenly slows down, it's likely because the cache was cleared. It will naturally recover after a few more launches.

Compatibility Issues

Rosetta is not 100% compatible. Here are some occasional issues encountered with Binance under Rosetta:

• Some graphical effects fail to render under translation (like chart highlight flashes).
• Slight aliasing in font rendering (macOS 14 and below).
• Occasional stuttering when dragging to select chart areas with the mouse.
• A "Rosetta is not available" error pops up on startup (very rare).

None of these issues exist on the native ARM version.

When Should You Use Rosetta

If you have already installed the Universal Binary or native ARM version, there is no need to actively use Rosetta.

Scenarios where it might be used:

• Temporarily debugging compatibility issues with the Intel version.
• Testing behavioral differences between Apple Silicon and Intel.
• A specific version of Binance was only released as an Intel package (very rare).

Regular users will basically never encounter these scenarios.

Uninstalling Rosetta 2

Theoretically, you can delete ~/Library/Apple/Rosetta, but:

• It requires root privileges or disabling SIP.
• Once deleted, no Intel APPs will be able to run.
• Reinstalling it requires downloading it again (around 300 MB).

In the vast majority of cases, there is no harm in keeping Rosetta, so there's no need to bother deleting it.

System Resources Comparison

The impact on system resources during long-term use:

• Disk usage: Rosetta itself is ~300 MB + cache (~100 MB per APP).
• Memory usage: Each Rosetta APP uses 30-40% more memory than native.
• Higher CPU usage during startup (for initial translation).
• CPU usage during long-term running is roughly on par with native.

Will Rosetta Still Be Needed in the Long Run?

Apple's official stance: Rosetta 2 is a transitional product and will be deprecated in a future major macOS version. However, in recent years (macOS 14 / 15), it is still being maintained, and its retirement date remains undetermined.

The official Binance version is currently a Universal Binary, so there is no situation where "only Intel is available". Therefore, Chinese Binance users won't be unable to install it due to lacking Rosetta.

FAQ

Q: Can the Intel version of Binance run smoothly using Rosetta? A: Yes. It is fully functional, though performance is slightly lower.

Q: Does Rosetta constantly consume memory after startup? A: No. Rosetta is a kernel module that is loaded on demand.

Q: Can I force the Universal Binary to use ARM? A: It uses ARM by default. When "Open using Rosetta" is unchecked, it runs in ARM mode.

Q: Is Rosetta 2 the same as Rosetta 1? A: No. Rosetta 1 was for PowerPC translation and has been retired. Rosetta 2 is for x86 translation.
