Macs have unusually large share of Steam sales
Valve as part of its first weekly update to the Mac Steam library revealed that Macs make up a disproportionately large number of game buyers. About 11 percent of downloads on the service now go to Macs, two thirds of which are portables. The developer also took a jab at Windows and noted that Portal was a fifth as likely to crash on Mac as it was on Windows platforms.
The ratio of Mac downloads is proportionately higher than Mac market share, which usually sits at less than five percent worldwide, but also suggests that an unusually large part of the Mac user base has used the service. If Portal counts towards purchases, it may also have skewed the results as the free downloads until May 24 may have led to disproportionately higher downloads.
A full report on OS distribution is expected in June, when Valve will have had a month's worth of statistics to better gauge results. User surveys and other details should appear roughly once a month.
