You guys already have an app out there for OS X (Bandizip) so you're (at least) moderately familiar with the platform and development specifications. Why not go a step forward and provide Mac users (particularly gamers--I know, I know, but we're few & proud) with the only way to record footage without compromising on performance (aka "gameplay footage"). The options we have on OS X are limited to very capable and high quality screencast recorders: great UI, really easy to use but non offer low-compression/raw capture ability...
Not a high priority request at all: keep pushing Bandicam to get better and better, even if only on Windows. But just an idea... The Mac is a great platform for indie/small development shops, so I'm sure you'll be fine!
Keep it up guys!
