[nitin710]

Description

• The esptool currently being shipped with EmotiBit FirmwareInstaller for macos is breaking for later version of macos (big sur and above, specifically versions released after M1 macs)
• Here is a link to the error seen on the console
  • MacOS Big Sur dlsym(RTLD_DEFAULT, kIOMasterPortDefault): symbol not found (ESPTOOL-82) espressif/esptool#540
  • Looks like it is a known issue that popped up with macOS big sur release.
• According to our documentation, we have been using esptool v3.3, but there are no developer notes specifying where the esptool binary was obtained from.
• The binary obtained form the esptool release page, is tested working with the following OS and hence is being shipped with the new firmware installer.
  • macOS mojave (Previous version of firmware installer was working without any issues)
  • macOS Big Sur
  • macOS Monterey
