Anyone here tried Mountain Lion yet?
I've recently installed it onto my household's three Macs, one of which is a 2011 Mini used as a media centre, mostly for playing ripped CDs via iTunes + Bit Perfect. No problems on any Mac so far except with CCleaner, which initially complained it was incompatible. A quick update via the App Store cured that instantly.
It will be interesting to see if the updated OS cures the one and only issue I had from the HiFi perspective. On my 'media centre' Mac Mini, now and again Spotify would object to playing sound via my HRT Streamer II+, in so far as the sound became distored and crackly. Flicking the default Output device to Internal then back to HRT Streamer always cured it for a while, til it decided it was throwing a strop again.
