Apple has just rolled out a supplemental software update for OS X 10.10.3 Yosemite release to fix a video driver bug that prevented Macs from booting up or resulting in 'No Display' signal while running certain apps meant for capturing video.
The company's latest release notes for the update read as follows:
MacRumors has confirmed that the video driver update is now available for download via the Mac App Store, while AppleInsider points out another bug wherein opening large JPEG files using QuickLook or Preview can cause a Mac running 10.10.3 to crash.
The bug was first spotted last week, when several users reported considerably larger bootup times in comparison to previous builds of OS X.
Some users are reported to have solved this problem by clearing up Mac's PRAM, while a few others tried resetting their startup disk selection via System Preferences. However, several other users have not been able to fix the issue even after trying these workarounds.
Meanwhile, those who are new to OS X 10.10.3 should note that the latest Yosemite build brings new Photos for OS X app, a new diversified emoji with revamped emoji picker, Spotlight suggestions for lookup, and a bunch of bug fixes and performance enhancements.
