Thanks, I was able to install FuseHFS by doing it in the order you suggested.

Unfortunately, I still can't mount the 7.5.3 .smi files - I get "legacy file must be converted."

Am I going about this the wrong way, or do I still not have FuseHFS installed correctly? I'm just looking to get up to 7.5.5 on my SE/30 and be able to put some programs on it. Right now it's a really cool vintage screen saver machine. xx(
