On a Tuesday this time ’round. Apple has seeded OS X Mavericks Developer Preview 7, a.k.a. OS X 13A569, to developers and little seems to have changed. However, after DP 7 installs, Notification Center spawns a persistent (i.e. must be clicked or dismissed) notification inviting the user to “See what’s new in OS X Mavericks,” which leads to a placeholder webpage with no active links.
Additionally, 9 to 5 Mac notes that Apple has added some new wallpapers in this seed.
According to knowledgeable sources, recent OS X Mavericks Developer Previews have been very stable and relatively trouble free, which could be a sign that development is winding and a gold master release not far off. The inclusion of the “what’s new” notification and web placeholder page would seem to back that assumption.
And, just for giggles, here is the OS X Mavericks Developer Preview 7 Seed Note, which includes a full listing of compatible Macs:
OS X Mavericks Developer Preview 7 is pre-release software. Do not use this pre-release software in a commercial operating environment or with important data. You should back up all of your data before installing this software and regularly back up data while using the software.
If an installation of OS X Mavericks Developer Preview 7 fails, try using Disk Utility from a Recovery HD to repair the disk.
