Broadband Optimiser is available for the Mac. Inevitably a GatesOS version will be available.
This is from the associated read me file.
Like most operating systems, MacOS X doesn't come out of the box to take full advantage of a high-speed, broadband internet connection. Luckily, because of its Unix base, there's an easy fix for that. By making certain tweaks to your network settings, you may be able to almost double your download speeds.
Broadband Optimizer works by increasing the memory buffers used for TCP transfers, so that data comes in bigger chunks at at time - Man-sized broadband chunks, not modem-sized kiddie chunks.
For this version I've removed a network check that turned out to be unnecessary - BBO should now work on PPPoE-based DSL connections without modification - and also cleaned up the code a bit.
