Sony really messed up when they introduced the XCP copy protection, without telling anybody about it. The XCP scheme messes with the registry and has other nasty tricks up it’s sleeves.
Oh well, as a Mac user there’s no problem, as with other copy-protection schemes, the XCP scheme only affects Wintel PCs. Anyway, on most Wintel PCs the copy protection schemes, I’ve seen, like on the Missy Elliott album THIS IS NOT A TEST!, has been quite simple to bypass: simply browse the CD using Explorer, then you can RIP it, it will fail if you just try to RIP it. I discovered this by chance.
