Ok Turey, I decided to fire up your installer on a Mac again. This time a Mac with OS X Tiger 10.4, and Java 1.5, so it should be good, right?
Well, I had to tell it where to install, which is a bit odd, because whatever window it is that asks for the install path, didn't have a box to just type in a directory, and didn't seem to have a way to go to the parent folder (..) either. So I decided I could just install it to a folder on my desktop and move it later. I would have rather just been able to install it straigh to the applications folder but I just could not find a way to do that.
Anway, I hit the next button, unchecked both boxes when asked to update only, and whether to get everything, since I didn't have anything to update and didn't want to download everything since I only wanted a few core files. So I hit next again, and the terminal window showed that it was going through and getting all of the mod files, and after awakenings showed up in the list, it just stopped. The main window didn't show anything but a big white area, that I could scroll up and down in. I couldn't hit next, couldn't click anything in the white area as far as I can tell, I wasn't prompted to do anything, it just stopped. A bit of a bug, although it's odd, because a few weeks ago, I think I used the gui version on a friend of mine's mac, and it seemed to work ok. I don't know if anything's been changed since then, just that it doesn't like my mac now.
Just thought I'd let you know, I'll help troubleshoot if you need it, or maybe you can help me if I'm just doing something wrong.
