'hf lto dump' macOS Illegal instruction: 4

[Kevin-Nakamoto]

Describe the bug Sending 'hf lto dump' from MacBook, Proxmark3 starts to read each data block of LTO-CM without any problems. However, at the end of the reading, the error message below shows up.

./pm3: line 215: 33004 Illegal instruction: 4 $CLIENT "$@"

To Reproduce

1. Place LTO cartridge on Proxmark3
2. Run the client
3. Send 'hf lto dump' from MacBook
4. See error

Expected behavior Dump files shall be stored on storage device.

Desktop (please complete the following information):

• OS: macOS Catalina version 10.15.5 (19F101)

• hw version

Additional context 'hf lto info' command works fine. Also, 'hf lto dump' works under WSL environment.
