The reason Hackintosh questions are banned is because there was a meta discussion which concluded they should be bannedthere was a meta discussion which concluded they should be banned. So write a comment citing this meta question, and flag as “blatantly off-topic” (which is a very bad name indeed, since the question isn't off-topic but instead banned by policy, but it's the only possibility).
(Why are Hackintosh questions banned despite the pro answer scoring higher than the against answer? Because in the distant past the pro answer scored lower, and the policy never changed.)
