When you try to install an Adobe product, you receive the message, "Case-sensitive drives not supported" in the Install Options panel. Or, you receive an error message such as the following:
- File system of setup volume not supported.
- This software cannot be installed because the file system of the OS volume is not supported.
- Unsupported OS version
- Unsupported filesystem on system disk
Install the product onto an HFS+ or HFSJ non-case-sensitive drive.
To determine whether your drive uses a supported file system, eg. Mac OS Extended (Journaled), open the Disk Utility application in your Applications/Utilities folder. The graphic below shows where the drive format information can be found. Click on your drive and make a note of the Format type.
Adobe products cannot be installed onto a volume that uses a case-sensitive file system, such as HSFX (HFS+) or UFS. This limitation applies to both the startup drive as well as the drive onto which the software is installed.
