Answer 1

MacOS is different, there is two way to solve this problem with sed in mac

• first ,use \'$'\n'' replace \n, it can work in MacOS:

  sed 's/,/\'$'\n''/g' file
  

• the second, just use an empty line:

  sed 's/,/\
  /g' file
  

• Ps. Pay attention the range separated by '

• the third, use gnu-sed replace the mac-sed
