Prescriptively speaking I think that all three (nothing, -re, -er) are legitimate; for reference the word is /ma.kabʁ/ in French, the cluster is clearly illegal in English so the variations can be seen as different “repairing” strategies. (I’d probably render it as /məkɑ:be/ but my non-native pronunciation is strongly biased towards British varieties, specially RP.)

Note YT comments are often a bit silly with prescriptions. Like trying to correct Steejo (a Scottish YouTuber) for, well, speaking Scottish English.
