Hi guys I have a MB Pro 2012, 15'', normal display with 8GB RAM, 512 Crucial SSD drive for the system and a 512 HDD instead of the optical drive, so I can enjoy a good Tera of space, half of which is lightning-fast. The hardware seems to be excellent, so I am starting to suspect that the newer systems present problems. One specific problem that I noticed on several occasions is the sound. When I am playing back some music, no matter from which drive, the sound sometimes skips (halts) for a fraction of a second, every two-three minutes or so. I ran all the tests for hardware with the ASD3S150 disk image on a USB stick: no hardware problems detected, memory is tip-top, sound card is fine. And in fact, when I use Windows (installed on the Boot Camp partition), the machine PURRS... and everything works like a charm. Shouldn't Mountain Lion load the song on the RAM, if not entirely at least a few Mega's of buffer, so even if the connection with the drive is interrupted it can play on smoothly? I am really perplexed. And increasingly disappointed in Apple. I am thinking of downgrading to Snow Leopard and checking what happens there. Any other suggestions?
