No they aren't. If Apple were listening, we wouldn't be expected to shell out $6000 for a machine where we're going to have to disable half the cores (and lose 40-60% of the remaining performance) to achieve "it might work" security (until the next Intel vuln is found). If Apple were listening they wouldn't be selling a freaking monitor stand for $1000. If Apple were listening, they wouldn't be forced to abandon bash because they can't be bothered to actually comply with the GPL (v3). Nobody can justify Apple at this point and the sooner it dies, the better.
