"Just noticed OWC released a new firmware update for their SSD's on March 5th. (2nd note on D/L page below.)
Did the update via USB flash drive, no issues. (I've got two 120GB Extreme Pro 6G SSDs in a late 2012 mac mini, Raid 0)
If your OWC SSD Firmware revision contains xxxA12F0 or xxxA13F0, then xxx365A12F0 or xxx365A13F0 is the most up-to-date revision, current as of October 20, 2011.
If your OWC SSD Firmware revision contains xxxABBF0, then 541ABBF0 is the most up-to-date revision, current as of March 5, 2014."
(D/L page also has info on requirements, instructions, and step-by-step install video)
The zip download has flash instructions and a DMG, but I didn't know what this was to address so I asked OWC about it. (If you're not having any problems, the old 'If it ain't broke, don't fix it' is often a good rule to follow.)
"Since last fall, the OWC firmware update utility has been universal and the online guide/info is detailed to make it as easy as possible to determine whether or not you currently have the latest firmware on the applicable OWC SSD Model.
Recently firmware version 5.4x was posted with support for OWC SSDs which use the Sandforce 2181/2281/2282 processors. This update primary includes support for newer flash types, but also includes support for one of our 240GB Electra 3G SSD models that was prior limited to 5.0.7 revision firmware.
Who needs 5.4.x? It is highly recommended for anyone currently with firmware 5.0.5 or lower. if you are running 5.0.6 or later, there is no truly pressing requirement - although we do recommend that users of Aura Pro and Mercury Extreme Pro 6G drives who haven't already updated to 5.2.x, update for best performance.
In general - if not sure and just want to have the latest firmware on your drive, the utility will identify your drive and only do an update that is correct and suitable for the drive(s) you have. The site shows how to check your current firmware version via About This Mac - and if you are already on a 5.2.x or later version, there is zero reason to update. We do expect another future firmware update to be available later this year which may do some things related to performance enhancements, if there are benefits - that will be one we push information for update out on. Otherwise - things quiet and all good. :)
Adds a security option to require that iOS devices or Macs be verified with a one-time, onscreen code before using AirPlay. Requires iOS 7.1 or later on an iOS device or a Mac with Mac OS X 10.9.2 or later.

Stability and performance

"I was severely affected by the "Mid-2013 Macbook Air screen goes black" problem, but OS X 10.9.2 fixed it. Also, I have a recent NEC EA244WMi and it works great via miniDP to DVI.
Kind Regards, Mattia"
