Apple on Thursday released a second beta build of its upcoming OS X 10.10.5 Yosemite update to developers for testing, including what appears to be only minor tweaks and bug fixes.
Like the first beta, today's build brings minor tweaks and bug fixes aimed at improving system stability, app compatibility and security.
Apple most recently updated its Mac operating system in June with the release of OS X 10.10.4, which brought a variety of fixes for problems with Photos, Mail and the infamous "discoveryd"service. That release also introduced TRIM support for third-party SSDs.
Developers can download OS X 10.10.5 Yosemite beta 2 via Software Update in the Mac App Store or through Apple's developer Web portal.
