Apple on Wednesday seeded the third beta of OS X 10.10.5 to developers, just one day short of a week after seeding beta two.
The new seed, build 14F25a, can be installed by developers via the “Update” tab in the Mac App Store, or can be downloaded via the Apple Developer Center.
OS X 10.10.5 beta 2 reportedly included a fix for the DYLD_PRINT_TO_FILE exploit that has been in the news the last few days. The patch for the security flaw will be included when OS X 10.10.5 is released to the public.
