I attempted to install CentOS 6.4 / FreePBX on a Mac Mini 2011 which use "Apple EFI implementation" to boot. No matter what is tried, the install media is only accessible over legacy CSM (Compatibility Support Module). As a result, CentOS 6.4 will NOT install in EFI mode.<br />
<br />
This bug here seems similar to bug 0006321 (Minimal CD will not install in UEFI mode) but it's not related to any missing directory / files.<br />
<br />
It seems that all CentOS media will be accepted as "non-EFI bootable media". When Windows 7 x64 or Windows 8 x64 DVD is inserted, there will be additionally an "EFI boot" option at my Mac Mini / iMac.
