Hello,
We are very sorry that this bug slipped through, it resulted from an attempt to increase efficiency, along with other essential bug-fixes that we have worked on for quite some time.
Our developer team reacted the minute we saw the first report, on sunday morning, and the download numbers of the OS X version for this fix were about the same as with the previous version within 24 hours.
The bug affected OS X users exclusively, and only after a restart of the computer.
Luckily, very few OS X users restart their computer on a daily basis, which definitely helped in this situation.
All in all, 6 days after release and 4 days after the quick update, we received 3 reports about this problem, and there is this very thread with 17 entries from 8 users.
So before alarming tens of thousands of users (which would have been too late for most affected users anyway), we decided to let our automatic update service help out in this situation, which, from our perspective today, turned out to be a good decision.
I fully understand that this is not a comfortable situation for everybody affected by this unfortunate bug.
Thank you so much for your input and help resolving it!
Best,
Paul
