Updated to 2.7 via AppStore today, but now Scrivener cannot open *.scriv files. It tells me to update the project, and when I try to do so, an error message pops up saying that it cannot create a backup and that the the update has been cancelled. I have lots of space. I’m on El Capitan GM and the last Scrivener beta (was it v2.6.5?) worked.
Sorry for the inconvenience. We’ve actually pulled Scrivener from the Mac App Store temporarily, and I’ve submitted a new build that fixes this bug. The problem is that Apple’s sandboxing security requirements mean that Scrivener is failing to create a backup of the project without permissions to access the folder; it should fall back onto backing up to the automatic backups folder, but if you haven’t set one up, it can’t (that’s the part that’s the bug - it should then fall back on asking the user where to back up).
We’ve pulled it mainly because this is going to confuse a lot of users and leave them stuck, as it’s not obvious how to get up and running. But the good news is that it is a very easy fix - just follow the instructions in the link below, and you should be able to update your projects fine:
