Thank you for the report. The traceback indicates that python is crashing when it attempts to decode its command line arguments into a wide character string. There should only be one argument, which is the path name of the main executable in the app. So I am guessing that when the locale is set to Korea, that path is being translated into Korean and perhaps encoded with an encoding other than the UTF-8 encoding which Python is expecting.
When you use the Finder does it show the /Applications folder with a Korean name?
Please try running /Applications/SageMath-9-3.app/Contents/MacOS/SageMath in your Terminal, using both a Korean keyboard and a US keyboard. What happens? Also please try running /usr/local/bin/sage in your Terminal, using both keyboards.
The Sage python3 spkg defines the constant _PyFORCE_UTF8_LOCALE.
Here it is in pyconfig.h:
#if defined(_Py_FORCE_UTF8_LOCALE) || defined(__APPLE__)
/* Use UTF-8 as filesystem encoding */
#define _Py_FORCE_UTF8_FS_ENCODING
#endif
When that constant is defined Py_DecodeLocale passes the strings in argv to _Py_DecodeUTF8Ex, which is where the crash occurs. So this means that Python is assuming that all command line arguments are UTF-8 encoded, but that assumption is apparently invalid when the SageMath-9-3 app is launched on a system with a Korean locale.
I am guessing that the UTF-8 assumption is valid when python is started by a shell. But when an app is launched by the macOS launchd, the argv array is constructed by launchd, not by the shell, and the launchd may be doing something different that depends on the locale.
I attempted to reproduce this crash by creating a new user on my macbook air with region set to South Korea, language to Korean and imput method to 2-Set Korean. However, that user was able to launch the SageMath-9-3 app. There was no crash with either user interface.
There was no crash with either user interface.
One possibility is that the crash only happens when some path (perhaps from the user name) contains Korean characters (as we saw with SnapPy and the Japanese version of Windows at one point). That said, UTF-8 can encode Korean just fine and indeed this seems to be the default way to do so these days. There are two distinct ways to do so though, as precomposed blocks or individual jamos.
One thing that puzzles me is that the crash occurs when Python is processing its argv array. That array should contain only one string, which should be the path to the main executable of the app. The app was installed in /Applications, so I am having a hard time imagining how decoding its path could lead to a crash. It is possible that the crash has nothing to do with Py_DecodeUTF8Ex (which seems unlikely to contain an illegal instruction). Perhaps that just happened to be the function that was executing when the gatekeeper killed the app for some signature-related reason. Apple seems to use the SIGILL signal in lots of situations which do not involve any illegal instructions. (Or maybe they reason that any instruction is illegal when executed by an app that they want to kill.)
It would be nice to know if the md5 hash of the diskimage is correct. Byeongsu, would it be possible for you to run the command below and verify that you get the same result?

Thank you very much for your rapid attention. To avoid locale issue, I just changed my Language as English, and change my user name with English name, and delete SageMath-9-3.app and install it again. However, I've still got the similar error.

Thanks for helping us find out what is causing this crash. I think we can rule out the locale issue and also the possibility of a corrupted disk image. So I guess the next thing to do would be for you to open Terminal.app and run the command:
sage
and report what happens. It would also be helpful if you could try running the commands:
sage -python
and
/Applications/SageMath-9-3.app/Contents/MacOS/SageMath
Thanks!
One more thing. It is important to drag the application to the trash and empty the trash rather than using a shell command like rm. The operating system updates its database of installed applications when an app is moved to the trash.
Thank you very much for your guidance. When I deleted, I used trash and empty the trash instead of rm. However, to avoid possible database update issues, I just roll-back my system (using TimeMachine) to the time when I didn't have SageMath, then re-install SageMath. Still, the error I reported above happens, and here is the result of errors I've got.

Again, thank you very much for your concern.
I have a macbook air with two disk partitions, one of which has Catalina on it. I upgraded the Catalina to 10.15.7 so I could test on the exact same hardware and OS version as you are using. I see no crash. (Interestingly, when installing the update I got messages reporting the time remaining in Korean. But at the end of the update they switched to English. This happened in spite of the fact that my test user with the Korean locale had been created on the Big Sur system, not the Catalina system, and subsequently deleted.)
At this point I am assuming that the app is being killed by Apple's system security policy daemon. Here are some things to try to find out why this might be happening.
Please run this command and report the result:
spctl --assess -t execute -vvvv /Applications/SageMath-9-3.app
Then run this command and see if the app will start afterwards:
sudo spctl --disable-master
After testing you should re-enable the policy daemon by running::
sudo spctl --enable-master
If the app starts when the policy daemon is disabled, you might consider resetting the policy database to its default state by running the command:
sudo spctl --reset-default
and then rebooting the system. I am not sure what all of the side effects of doing that will be, but I do know that you will have to agree again to run apps which were not purchased from the app store.
Looking at the detailed info provided, this particular MacBook Air came out in 2012 and has an i7-3667U processor which was the third generation (Ivy Bridge) of the Intel Core processors. Which means it doesn't support the AVX2 processor instructions introduced in the fourth generation (Haswell). So possibly this is an actual illegal hardware instruction? Though I would not expect sage -python
to invoke any AVX2 instructions. The FMA instructions were also introduced in the fourth generation.
Wow. I am sure you are right. The app really does contain an illegal instruction for this computer. It sounds like we don't support macbook air computers build before July 2013.
I don't know of any way to build Sage for Ivy Bridge processors other than by building it on a machine which has one.
I have one of those cylindrical MacPros (circa 2014) with an Ivy Bridge processor, but it's currently inaccessible. It also runs 10.12 which is too old for the current SageMath app. I think the folks who build Sage for Conda have been able to suppress such pesky instructions see https://github.com/conda-forge/sage-feedstock/issues/57
I disassembled libpython3.9.dylib and found many instances of vmovapd, which is an AVX instruction. Many of them reference addresses relative to dyld_stub_binder. So maybe clang uses AVX instructions to speed up dynamic linking, which would mean that they are ubiquitous.
The crash occurs at offset 799532 = 0xc332c in libpython3.9. In the disassembled library I find: c332c: c4 e2 7d 59 db vpbroadcastq %xmm3, %ymm3 The vpbroadcastq instruction is an AVX2 instruction. So, I guess that settles this question.
The next question is what to do about it. Do we want to try to compile sage for old CPUs? Or make two versions of the app? Presumably the first option would make Sage slower. And I have no idea whether the linear algebra libraries would be able to handle that.
It appears that clang has an option -mno-avx2 which could presumably be added to CFLAGS.
The more sophisticated numerics libraries include code for all different processors and enable the most modern possible version at runtime rather than compile time. So those don't actually take a performance hit as I understand it, though other code might.
I suggest @byeongsuyu try installing via Conda, which I believe is compiled to maximize the number of machines it works on. At least on Linux, I regularly use the Conda version with processors this old (or possibly even older) on a campus cluster.
Thank you very much @culler and @NathanDunfield for your advice. Now I just compiled Sage 9.3. from the source and it works.
Thank you very much for your report! I will add a warning on the release page that the app requires at least a Haswell generation Intel CPU. I am glad that you were able to successfully compile sage on your laptop. That is probably the best solution in your case.
I've download the latest release of SageMath-9-3.dmg. I follow the instructions 1) move app file into Application folder 2) Install pkg file. Then I just execute SageMath-9-3.app as usual in the Finder. Then it says that the execution was closed due to error. Below is the error message I've got.
