Is there anyone run this successfully under macOS WeChat v3.1+ ?

I have some trouble with frida WeChat.exe under M1 with WeChat MacOS v3.1.5

I have this problem: (I have disabled the SIP and enabled the arm64e, it works with Safari without any problem):

$ frida WeChat

Hi huan, I don't own an M1 Mac so I cannot help you.

Also, if you have a question about running Frida, please consider opening an issue at https://github.com/frida/frida

Hi, thanks for your quick reply!

Besides the M1 Mac, I have tried the WeChat v3.1.5 on the Intel x86 mac air, which got the same result: Failed to attach: process is dead.

What WeChat version are you using with the wechat-decipher-macos, have you tried the last version and does it works?

Hmmm, that's weird. I just tried the latest version of WeChat and the scripts work on my x86 MacBook Pro. Here is the System Version Information
