System Requirements
Windows XP / Vista / 7 / 8, Mac OS X
* Mac OS X Lion 10.7.4 users may experience unstable connections due to microchip incompatibility. Where possible, we recommend upgrading your OS X to Mountain Lion 10.8.2 or later.
If you encounter other performance concerns, please contact our customer support with your operating system information. We can then provide guidance on how to upgrade your hub's microchip firmware.
Note
1. The charging port (5V 2A) is designed for charging your mobile devices only and will not support data transfers.
2. 2.4 GHz wireless devices, such as wireless keyboards and mouse adapters, may not work in close proximity to USB 3.0 devices or hubs. Connecting to a USB 2.0 port is recommended.
3. For maximum performance, connected devices should not exceed a combined current of 7A. Otherwise, output current may become unstable or disconnect entirely.
4. Some USB 3.0 devices require a direct connection to host USB 3.0 ports, including some USB 3.0 hard disks.
5. Please note that Apple now provides an official update for MacBook Air and MacBook Pro computers purchased in June 2012. This update improves USB 3.0 performance and compatibility and can be downloaded from the official Apple website as "MacBook Air and MacBook Pro Update 2.0." Please contact our support team if you cannot locate this update.

Good news Mac owners! Apple has released a graphics and USB focused update just for late model, Mid 2012 MacBook models including all Mac notebooks released in June 2012. This update includes graphics performance and reliability enhancements and improves compatibility with some USB devices.
As with any OS X update, simply choose updates in the App Store or choose Software Update from the Apple menu. Once all prerequisites are installed (which include 10.8.2), the update will appear.
Details on the update are rather sparse at the moment, however initial findings on the 11 inch Air I use as a primary work laptop are positive. After installing the update, some U3 Communicator HD docks which I had previously identified as defective actually worked consistently and at normal speeds.
Ive also noticed better reliability on the arrangement of the quad display panel I use with the tiny Air and a set of our DisplayLink-based UGA-165 adapters. Previously I could virtually never reboot and have my display arrangement persist, but now that seems to have been corrected- however this probably has more to do with the unusual number of hubs and devices I go through in day to day equipment testing and the constant swapping of ports that comes with it.
One frustrating issue that persists is when an USB storage volume unexpectedly disconnects, finder will freeze- immediately if you instruct it to eject the improperly disconnected volume. Forcing a reboot corrects the issue, however the system is largely unresponsive until the reboot which of course could result in data loss.
Wed love to hear your input on how this update is affecting your Plugable devices on those shiny new MacBooks!
MacRumors of course has a thread on the topic with very active discussion:

If anyone has either of these and has tested it let me know.
I may be careful about purchasing one of the other products unless they have been upgraded and say what is is compatible with.
