I then question your need for low latency? OS X and MacOS requires just as much work to get to the lowest latency and your handicapped if your have an Apple laptop. Your latency will be about the same as PusleAudio on Linux if you use default OS X MacOS settings. In most real world settings Windows will get a lower latency mostly due to better hardware on a Professional setup compared to the less then top end audio of Apple. Apple machine require a lot of engineering in the software to achieve low latency.

Here is the focusrite help page dealing with latency and what you must turn off for recording. https://support.focusrite.com/hc/en-gb/articles/207546515-Op...

Those links are either out of date or completely incorrect. None of this has ever been necessary for me on a Mac.

Focusrite doesn't even offer Mac drivers for most of their products, as the support is built in, for example[0], so I don't know why it's advising you to update your drivers.

Seriously. A friend brought over his 2i4 for a project and my Mac was able to plug-and-play with it at 5ms latency.

That page is "dissuade people from calling tech support", not the reality of how audio actually works on OS X.

There is no way you have 5ms latency with a USB port. Your measuring it wrong. USB audio devices have built in buffers that add to your 5ms latency.

yes its 2009 but it is still sound science.
