Hello all, I'm kind of new to Macs and all. I recently re-installed Leopard 10.5.5 and made the upgrade to 10.5.6 Everything works perfectly fine. The only thing is that when sarting up and also when shutting down, I get instead of the Apple logo and the little spinning wheel thingy, a black startup screen that looks like DOS. The Mac starts fine, it's just the interface/screen that is not normal. My local mac shop told me to type into Terminal the following code but to no avail: nvram boot-args="" The command is not recognized. They then advised me to reinstall Leopard again but as I have customized the mac already I wish to keep everything as it is and solve this problem without reinstalling. Does anyone have any ideas? Thanks!
