Support for this product has ended. iPartition works fine on macOS 10.12 and earlier, but has some problems on macOS 10.13 (High Sierra). There will be no further updates or bug fixes; the product will remain available for download and purchase for the benefit of users running earlier versions of the macOS.
N.B. WE WILL NO LONGER OFFER REFUNDS FOR CUSTOMERS WHO BUY THIS PRODUCT AND IGNORE THE MESSAGES ABOUT FUNCTIONAL LIMITATIONS ON HIGH SIERRA (macOS 10.13).
Users running versions of macOS prior to Sierra (10.12), please see the compatibility chart to find the correct version for your system.
There are issues with macOS 10.13 High Sierra that affect some functionality.
If you have an SSD-based system and are running macOS 10.13, you will be using APFS, not HFS+; iPartition does not support APFS.
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: iPartition does not support Core Storage (Fusion Drive and File Vault 2 both use this volume format). You will also need a separate boot device — typically a Flash drive will suffice.
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.
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.
Convert case-sensitive HFS+ to normal HFS+ and vice-versa, a real boon if you’ve made the wrong choice in the past.
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.
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.
N.B. iPartition 3.5 supports Mac OS X 10.10 Yosemite to macOS 10.12 Sierra. For older releases, please see here.
iPartition does not support macOS 10.13 at present as Apple has not released any documentation for APFS.
Pre-release versions of Mac OS X are not officially supported. They may work, or they may not.
