No, OSX has done this for a long time, not just with Mavericks. Here's a post from 2006 mentioning the message; http://forums.macrumors.com/showthread.php?t=233661

I still don't seem to bother using my E17, if anyone would like to buy it (in perfect condition, barely used) please drop me a PM :)

Quote: There's a hold button on the device, slide it into the hold position and the power button can't be accidentally pressed.

Quote: I can definitely hear the difference between 128 and 160, 192 and above - I know that for certain as it was the purchase of some Shure E2C in-ear phones a few years back which caused me to start to get interested in HiFi stuff. It also caused me to re-rip all my MP3's from the...

Quote: I'd be interested to know which track(s) and passages you can hear a difference on - just for my own interest really. It'd be interesting to know if either "my ears just ain't that good" or whether it's a case of training my ear to be able to hear the difference...   I know...

My E17 turned up a couple of weeks ago and I've listened to it a fair bit since then.   Using the LOD from the iPhone 4S to the E17 and then Beyer DT1350's, I can't discern any difference between the E17 and the iPhone 4S's normal headphone out.   Running the E17 from USB at 24bit, 96k...

First off, an apology as this is slightly off topic, I'm looking to drive a pair of Mackie HR624's from an Airport Express and a DAC of some description. I would also like the DAC/AMP to be re-usable with my cans at some later point however, so I think this is still relevant to this forum.  ...

Quote: Nope, but I will once my E17 arrives. Supplier is currently quoting March 16th for them receiving stock, but that has slipped once already...

Well over a year since I received the AUNE, so I would imagine it's well and truly burned in by now :)   I've since also aquired a pair of Beyerdynamic DT-1350's for use mainly in the office at work. The Grado's still sound the best, to my ears, but they're not ideal for the office with...

Well nobody else replied, so I may as well update the post :)   I ended up buying an AUNE Mk2 off eBay which was delivered today. First impressions are that the audio quality is better than I was getting from the RealTek ALC888 built into my mobo.   I'm running the AUNE via the SP-DIF...

Hey all, First post so be gentle with me - I've recently taken delivery of a lovely pair of Grado SR-325is which I'm currently driving straight from an iPod. I realise I need an amp to get the best performance from the cans however. I'd intended on using my normal desktop amp (an old...
