I'm using a Mac with OS 10.4.11 and I tried to install NeoScene but it said it needs minimum of 10.45. Does anyone have that system on their Mac?? Reason is I can't find an upgrade like that. I'd like to know how I can upgrade.

I think you're talking about 10.5.x

I believe neoscene needs leopard to work on the newer builds.

You may be right but the message I get when I double click on the install says minimum 10.45. I'll send them a message. Thanks for the hint.

OK. I sent them a message and they will address that mistake. It does need Leopard.
