Yeah, it looks like the whole iCloud thing could get old fast. I'll be digging into my AppStore issue tonight. It might be something as simple as moving over to Ethernet from WiFi for a bit, but I'm sure it'll come right eventually.
If I remember correctly I just downloaded one of the Generic OpenELEC builds. I can't stress enough how much fun it is to play with. Consider yourself warned! It's pretty darn cool.
OS X Server was a piece of cake to get running. It's now just a small-ish App you download from the AppStore, so nowhere near as complex as the Snow Leopard server installs I've done on these machines in the past. I haven't put it through much of a grilling just yet, mostly just basic local network File Sharing and Time Machine back ups over Wifi - I still need to get it onto my gigabit ethernet network to get some better data throughput and do some proper experimenting with Remote Access and VPN etc. Unfortunately, my new place doesn't have any built-in CAT5 cabling or infrastructure for wired home networking, so maybe another DIY project for the summer... Hmmmmm.
As for the offer regarding your graphics card... what I actually should have explained was that it was to edit or help you edit your AMD6000Controller.kext to correctly match your Radeon 6450's connector info to your card's framebuffer personality. That way when you enable GraphEnabler with "Yes" at boot, OS X sends the correct info to both About This Mac and System Profiler automatically and your card is recognized with it's correct name rather than the generic one you're getting now. I used to have a thread over at TonyMacx86 doing this for a few Radeon HD 5450 owners, basically dumping their VBIOS files and figuring out the correct changes to make to the connector table using bcc9 and mucha's methods from elsewhere on these forums
Cheers for now!
