HFS was designed to run acceptably for low memory 680×0 systems. XFS design meant to maximize durability and high performance for Irix workstations with fast 32 bit processors and lots of memory. Mountain Lion can only boot in 64-bit mode, so any Mac that has 32-bit EFI boot firmware wont be able to run it.
Compare this with XFS which was designed by SGI for SGI workstations. While the earlier Mac Pros have 64-bit processors, the Extensible Firmware Interface boot firmware is 32-bit. HFS was designed for MacOS 7 or 8 around 1995. When I had sector problems on ext4 disks, lost almost nothing.Ĥ: designed in a different era: HFS+ is basically HFS with journaling. I’ve had sector problems on HFS+ disk on two separate occasions and lost just about everything. Look at XFS which is designedģ: possibly subjective – but HFS+ is much less reliable than ext4/xfs in the face of bad sectors.
Anyway, just about everything was faster in LInux and XFS, such as file creation/delete/move and compilations.Ģ: Journaling is an afterthought. Also, Boot Camp 5 is compatible with 64-bit Windows 7 and 8, not only Windows 8. Also, the option to start your computer in 32-bit mode isn't available anymore in Mountain Lion.

Apple really needs to dump HFS+ and get a real file system.ġ: Performance – unfortunately its really hard to make this quantitative as HFS driver for LInux sucks and xfs / ext3 … driver for OSX runs in user space, so comps I made were running the same program in OSX, then re-booting to Linux. OS X Mountain Lion is a full 64-bit operating system, with the kernel and extensions in 64-bit.
