This document will continue to be updated as and when new information becomes available.

If your printer model is not listed in the document please contact your local Oki support representative.

The following limitations may be experienced when an OS X Lion driver from the website is used on a 'Mountain Lion' operating system:

1. Default setting of GateKeeper
The following message or similar will appear and prevent startup:
"MAC_OS_Lion" can't be opened because it is from an unidentified developer.
Your security preferences allow installation only apps from the Mac App Store and identified developers.

* Please note this message will not appear during installation from the CD.

Please follow the procedure below to launch OS X Lion supported software downloaded from the web:

(i) Press the Control key and click software
(ii) Select “Open” form the pop-up menu
(iii) Click “Open”

Alternately, you can change the default settings: Changing OS settings and enabling installation with 'Mountain Lion'

2. Add a Printer
The message "The printer software was installed incorrectly. Would you like it to be repaired?" will appear when you click on the [Add] button after selecting the device and the driver in the procedure to 'Add a Printer'.

- When the [Repair] button is pressed, some file authorities will be changed and it will continue the installation process.
- When the [Cancel] button is pressed, the installation process will end.

The above will also occur with the software from the CD.

3. Scanner Driver (Image Capture)
The 'Lion' driver will not scan correctly on the 'Mountain Lion' operating system.
The Scanner driver's User interface is displayed as collapsed.
When the [Overview] button and [Scan] button are clicked the message "Scanner reported an error" is displayed.

The Scanner ICA Driver version 1.0.8 has been updated to support Image Capture with the following models.
