this arch is in fact arm64e due to apple's changing in arch code.

I'm sure this is well beyond the purpose & scope of your application, but figured I'd share. Using XMachOViewer with a M68k Mach-O file from NeXTSTEP results in the heuristics scan item saying "Unknown". Everything else works as it should. Binary available at http://gamers.org/pub/idgames/idstuff/doom/nextstep/NeXTdoom1_2.tar.gz.

Will it support for .a .dylib .dsym file types?

I found a site talking about version on .desktop files and apparently it's part of the desktop entry specifications.

I was completely wrong originally

Install package: xmachoviewer_mac_qt6_0.04.pkg

When opened, resolution of the icon will change from original 256x256 to about 55x55, and open the app's information to change its icon doesn't work either

original:

This problem was not found on XPEViewer and XELFViewer

When I look into the source code the load command definitions seem to be a bit old, the latest LC is 0x30 where dyld already knows up to 0x34:
https://opensource.apple.com/source/cctools/cctools-927.0.2/include/mach-o/loader.h.auto.html

#define LC_NOTE 0x31 /* arbitrary data included within a Mach-O file */
#define LC_BUILD_VERSION 0x32 /* build for platform min OS version */
#define LC_DYLD_EXPORTS_TRIE (0x33 | LC_REQ_DYLD) /* used with linkedit_data_command, payload is trie */
#define LC_DYLD_CHAINED_FIXUPS (0x34 | LC_REQ_DYLD) /* used with linkedit_data_command */

The latter two replace starting with iOS15 LC_DYLD_INFO/LC_DYLD_INFO_ONLY
