Success
I was able to install SLS - installation was sluggish, but not overly slow (perhaps 30 minutes). This is probably due to the fact that my iMac only has 2 GB of physical memory, only half of which was devoted to Parallels, and the system requirements for SLS are 2 GB just for itself. Things are a tad sluggish, but once again not overly so - boot times are around 1.5 minutes, applications open in a decent amount of time - no troubles there. Once again, I've no doubt that this is due to this being a 1.83 GHz Core Duo iMac. The problem I am having is getting bridged networking to work. I've tried setting the IP address in SLS both manually and using DHCP; it has no access to the internet in either case, but when set to use DHCP it seems to pull the correct settings from the router. Playing with the DNS server address does not change this (but was my only thought on the matter). Any thoughts on this matter?
