The short answer is no!Has anyone seen anything as to when Steam clients would be able to preview some of this?
The longer answer is that a Steam or Mac fix test version, or maybe the full fix release (possibly SP6 HF) will be released when they are ready. Experience should tell you that fixes posted in haste to satisfy demands are usually a source of more problems. Perhaps that is what caused this problem in the first place but to be fair, N3V reported that none of their QA and internal tests revealed the problem and none of their initial beta testers reported the problem (although some have disputed that). So how much testing do you do before releasing anything?
