If you have an older version of Mac OS X, you may need an older release of iDefrag. The following table lists versions of iDefrag against versions of Mac OS X:
|Mac OS X Version||Latest Compatible iDefrag||Status|
|OS X 10.12||Current release||Supported|
|OS X 10.11||5.1.3||Supported|
|OS X 10.10||5.1.3||Supported|
|OS X 10.9||2.2.8||Not supported|
|OS X 10.8||2.2.8||Not supported|
|OS X 10.7||2.2.8||Not supported|
|OS X 10.6.8||2.2.8||Not supported|
|OS X 10.5.8||2.0.5||Not supported|
|OS X 10.4.11||2.0.5||Not supported|
|OS X 10.3.9||1.7.3||Not supported|
To download one of the above versions, just click the link. Please do take note of the major version numbers — if you have purchased version 2, you can only use your license with a version starting 2, and so on. See our article on version numbering for more information.
If an update breaks iDefrag for one of the OS X versions marked “Supported” above, this is a bug and will be fixed. We do not regard problems on unsupported versions of OS X as a bug, even if the table above indicates that a given version will work on that version of OS X.
N.B. iDefrag 5 customers who need to use iDefrag 2 can obtain a suitable license by e-mailing firstname.lastname@example.org. You cannot activate iDefrag 2 with an iDefrag 5 license, or vice-versa.
