A couple of developers have contacted me with the question about which versions of Mac OS X scientists seem to be using and I thought it might be useful to try and get a feel for usage.

The page detailing the compatibility of scientific applications under Yosemite (Mac OS X 10.10.x) has proved to be very popular, with over 6,000 hits to date. Looking at the website stats for this month Mac OS X 10.10 accounts for 65% of the desktop visitors and 10.9 for a further 23%. The remainder is split pretty evenly over 10.8 to 10.4. The poll below gives you a chance to provide additional evidence and I’ll pass the results back to the developers.

Thanks for taking the time to vote and please pass the link on so we can get as broad a coverage as possible.
