Sandvox is compatible with OS X Mavericks!
We've been running Mavericks since the first developer preview at WWDC. Sandvox has been working great for us the whole time and we've not seen any problems that are specific to Mavericks. So if you have upgraded to 10.9 — or you weren’t sure whether to upgrade or not — don’t let Sandvox stop you from experiencing this wonderful new update from Apple!
