Apple Seeds Fourth OS X 10.11.5 El Capitan Beta to Developers and Public Beta Testers
Apple today seeded the fourth beta of an upcoming OS X 10.11.5 El Capitan update to developers and public beta testers, one week after releasing the third OS X 10.11.5 beta and more than a month after releasing OS X 10.11.4, the fourth update to the El Capitan operating system. OS X 10.11.5 has been in testing since April 6.
The fourth beta of OS X 10.11.5 can be downloaded through the software update mechanism in the Mac App Store or through the Apple Developer Center (developers only).

OS X 10.11.5 focuses on security enhancements, performance improvements, and bug fixes to address problems that have surfaced since the release of OS X 10.11.4. As with prior betas, the changes appear to be minor in scope, and no obvious outward-facing tweaks have been discovered in the first three OS X 10.11.5 betas.
We'll update this post if any new features are found in the fourth beta.

Production theater company IMAX has responded in a mixed way to Apple's embrace of a 1:1.4 aspect ratio on the iPhone Duo's inner and outer displays. The boxier ratio happens to be very close to the classic "full-frame" IMAX 1.43:1 aspect ratio, which comes from the geometry of the company's original 15-perforation/70mm film system.
