Repartition your disk with ease
iPartition’s intelligent partitioning algorithm makes it easy to repartition your Mac OS X or PC disks — just select a partition and drag the slider to resize it, with no need to tediously shuffle partitions around yourself to get the disk the way you want.
For Boot Camp users, iPartition natively supports HFS, HFS+, FAT and NTFS filesystems, which makes it a breeze to resize your Windows partition if you find that you made it the wrong size.
Please note: the current version of iPartition does not fully support Mac OS X Yosemite, nor does it feature support for Core Storage (the subsystem behind File Vault and the Fusion Drive). You will need a separate boot device — for non-Yosemite systems, this could just be a Flash drive, which you can set-up with the Create Boot Disk feature in iPartition. For Yosemite systems, presently you will need an external disk with another install of Mac OS X.
N.B. iPartition is not compatible with Drobo. Attempting to repartition a Drobo unit, or any other thin provisioned unit, may result in data loss.
iPartition fully supports HFS, HFS+, FAT and NTFS out of the box. It also knows the correct partition types for a whole load more, though it can’t format them or non-destructively resize them.
Repartition without reformatting
Want to change the size of a partition that’s currently full of data? iPartition supports non-destructive resize of HFS+, FAT and NTFS partitions.
Case sensitivity conversion
Convert case-sensitive HFS+ to normal HFS+ and vice-versa, a real boon if you’ve made the wrong choice in the past.
Supports PC disks too
iPartition 3 supports PC partition tables as well as Apple and GUID Partition Table formats used on the Mac.
Unlike other partitioning utilities, iPartition is smart enough to work out where your partitions need to go without having to ask you to shuffle them around yourself. All you need do is tell it what size to make them and let it worry about the rest.
Power cut during partitioning? No problem.
Partitioning is risky, but we’ve got you covered — while we don’t recommend relying on it, iPartition can normally recover the disk even if you pull the plug during repartitioning.
Requires Intel Mac OS X 10.6 or later.
