Unfortunately hindi na gumagana yung pag disable ng autoboot. I've tried that before, also yung pag enable ng startup chime. Seems like Apple disabled it on newer firmwares. Yup I've asked them to continue testing. They did not seem to take time in troubleshooting a "random" issue. I even have proof from the system.log. Well, admittedly the problem is very hard to reproduce and diagnostics show nothing. They just need to do more intensive testing sana. Sana they will also realize na I won't be bringing my unit in if it has no issues and it's working as expected..
