Due to the various issues described in the resources linked below, we recommend that most users do NOT apply the free update to OS X 10.9 Mavericks. Read on for further details about specific product issues under 10.9—older OS X version compatibility information is at the bottom of this page.

OS X 10.9 Mavericks currently has major issues with multi-monitor support affecting all DisplayLink based products. As a result, USB attached display adapters are not recommended for use under 10.9 Mavericks—most other Plugable products should work well with Mavericks.

OS X 10.9 users will also need driver updates for our USB3-E1000 USB 3.0 network adapter and PL2303-DB9 USB 2.0 serial adapter—these updated versions can be obtained here.

Other Plugable products should work well with 10.9 Mavericks based on testing of the “Golden Master” developer release. We will update this page with additional details as they become available.

A few general notes on OS X compatibility:

  1. USB 3.0 add-in cards for older Mac Pros (most common one is from a company called Caldigit, another is the Sonnet Allegro) use a very limited, non-Apple USB 3.0 stack that simply won’t work with most USB 3.0 devices on the market today. The add-in card can delivery only very limited USB 3.0 compatibility (because its 3rd party USB 3.0 software stack predates Apple’s own stack). Unless a USB 3.0 device is explicitly listed by the card as being compatible, please assume the device will not work.
  2. New Mac OS X point releases have a history of requiring updates in individual drivers for various USB devices. Be cautious about upgrading your Mac OS X version, particularly for complex devices like USB graphics and docking. If you’re not the adventurous sort, we recommend searching or checking at Plugable for any issues and waiting until there’s evidence from others that the upgrade will be smooth, before installing the upgrade yourself.
  3. Several Apple devices- like the “SuperDrive” and some Apple keyboards with USB ports built in- require more power than is specified by USB-IF standards.  These devices will need to be connected directly to your Mac to operate normally, and cannot be used via a USB hub.
