just sharing my experience. Recently my two month old imac 27 wont open and is just stucked at the apple logo and then suddenly it would turn off by itself. After trying to restart it multiple times and using the Disk Utility, it diagnosed the Macintosh HD is corrupt and needs to be repaired. Even after clicking Repair Disk it just didnt work out. So finally I decided to bring it to a service center at Greenhills. The recommendation is to reformat and to reinstall the OS. I was informed that the corrupted hd could have been caused by installing updates like Yosemite which was not properly completed or downloaded. According to the tech personnel of Beyond the Box even if the item is under warranty it doesn't include the software so I paid P750. for the reformat and reinstall OS. I got my imac on the same day after three hours. Im just wondering with other Apple premium resellers if they also charge for the service for reformat and reinstall even if the item is still under warranty and purchased from them directly. I inquired at Istudio and they said if the item was purchased from them and still under warranty the reformat /reinstall is free . Otherwise the regular fee is around P1k. Although, Im really glad I got my imac repaired promptly I was wondering what other stores aside from Istudio gives free reformat and reinstall service for Macs that are still under warranty.
