Need a custom Bot that will Thumbs up a Specific comment on youtube for Mac

I have 50 youtube accounts premade all with identical passwords. I want a bot to log in and out of these accounts and thumbs up a specific comment that i choose thus making it the top comment.

So it logs into the account thumbs up the comment i have left logs out of the account.
Repeat until all accounts have thumbed up my comment.

I essentially want to promote my music by havein the top comment and to have the top comment you have to have the most thumbs up.
