I didn't expect Jaguar to work. It sounds like there's two issues in play here, firstly the script isn't writing correctly, possibly due to limitations with the command line tools that LeopardAssist depends on (grep, head, machine, nvram, sed, sudo, sysctl, system_profiler, tr, whoami) or the flags passed on to those tools. Secondly it sounds like the REALbasic 2007 runtime, which implements its own controls, requires Panther or higher.

So I think it's safe to say that LeopardAssist on Jaguar is a write-off.

I've also made a couple of changes based on a couple of requests I've received in recent weeks:

- Boot From USB (on supported systems). Makes use of the boot command boot ud:,\\:tbxi.

- Supported on Power Mac G5s / iMac G5s. These machines already support Leopard, but LeopardAssist will still configure the boot device and startup flags.

I just need to test LeopardAssist with these alterations in place to make sure the code changes haven't affected the other features. It's likely that I'll release this modified version for testing before it's cleared to the public as well, but we're definitely a step closer.
