Mac OS X 10.7.3 Breaks Display Rotation

We recommend not upgrading your Mac to the OS X 10.7.3 release if you are using a Plugable graphics display adapter.

This latest upgrade to the Mac OS was made publicly available at the beginning of this month. Unfortunately it breaks display rotation functionality in all third-party display drivers.

DisplayLink, the maker of the graphics chipset in Plugable graphics display adapters, is in touch with Apple about potential fixes for the problem. When word of a solution arrives, we’ll post it on the Plugable blog.

Meanwhile, if you already have upgraded to 10.7.3 and now find that your rotated display connected throgh a third-party graphics display adapter seems to be broken, here are the steps posted in the DisplayLink Mac forum ( to restore functionality:.

1. Shut down the Mac.

2. Disconnect the Plugable graphics display adapter.

3. Boot in safe mode by pressing and holding the shift key after the startup tone (

4. Open the Display preferences in System preferences.

5. Reboot.

6. Connect your Plugable graphics display adapter. The display should work again, and its rotation should be back to standard.

If you have upgraded to 10.7.3 but do not use display rotation, you might not see any problems. However, we still do not recommend updating to 10.7.3 until DisplayLink is certain that all display-management functionality is stable in this version of Mac OS X.

DisplayLink’s latest Mac driver works properly with OS X 10.7.2 and earlier OS X releases.
