There's a reason we split this Pointers tutorial into two, and it's only partly because we like suspense. Previously, we showed you how to install a copy of the OS X installer onto a bootable USB stick and when you knew how, it was quite easy. Have a read of the instructions for that if this is all you need to do. We just reckon that the odds are that instead, you'll need to make one USB stick with multiple different versions of OS X ready to be installed. The principle is the same, and the benefits of having these installers with you are the same, but the process is much more involved.
A recently-published exploit that could allow attackers to gain unchecked root-level access, following the user initially installing it, has been patched in the forthcoming OS X 10.10.5 update, and in this fall's 10.11 El Capitan upgrade. The flaw, which was introduced in Yosemite's error-logging functions. Though widely reported as hair-on-fire dangerous, the exploit merely installs adware and junkware such as Genio and MacKeeper, and requires users to actively install it before it gains root privileges.
Following an earlier release of a second beta of iOS 8.4.1 for developers, Apple late on Thursday released both the second developer beta and a public beta version of the next minor update to OS X Yosemite, 10.10.5. The new build, 14F19a, comes two weeks after the first beta, and has no new information on the usual assortment of tweaks and bug fixes such releases usually entail. The final version of the update is expected ahead of the next major release, OS X 10.11 El Capitan, which should appear in September.
Two days after issuing a developer beta of the next minor update to OS X, Apple has taken the release public to pre-registered testers. Version 10.10.5 continues the series of bug-fix and tweaking to Yosemite, and is distinct and separate from the public beta for the upcoming major update, OS X 10.11 El Capitan, that was released exactly a week ago. The new public beta of 10.10.5 is identical to the first developer beta.
Among a storm of major updates, Apple has also issues updated versions of Safari for the three versions of OS X currently supported: Mountain Lion (10.8), Mavericks (10.9), and Yosemite (10.10). In addition to the updated Safari versions (6.2.7, 7.1.7, and 8.0.7 respectively), the company also issued the first developer beta of the forthcoming Safari 9.0, which will accompany the release of OS X 10.11 this fall, and a pair of EFI updates.
On Wednesday, Apple updated its Safari browser for OS X 10.8 (Mountain Lion), 10.9 (Mavericks), and 10.10 (Yosemite) to versions 6.2.6, 7.1.6, and 8.0.6, respectively. The updates applied patches to discovered security flaws in WebKit, the underlying engine of Safari, that could have been exploited if left unfixed. Potential problems that could have arisen from the flaws could have resulted in crashes, access to filesystem contents, or allowing a site to spoof a user interface. The updates as relevant will appear in the Updates tab of the Mac App Store.
Researchers from security firm Synack have determined that Apple's latest patch for the "Rootpipe" privilege escalation flaw remain mostly unfixed, even on OS X 10.10 "Yosemite." Ex-NSA staff member Patrick Wardle examined the new patch, and found a new path around Apple's security fix, leaving the computer unprotected from hostile users with physical access. In other developments, the malware is loose in the wild and has been for some time, but is a discrete app and still not a remote attack.
Just a week after the official release of OS X Yosemite 10.10.3 and days after the first beta of iOS 8.4, Apple has posted the first 10.10.4 beta for developers and testers, though it is has not been (and is not likely to be) made available to public beta testers until future builds are released. The sparse announcement of the new beta says only that the update focuses on "stability, compatibility, and security of your Mac," which suggests it will build on the improvements made in 10.10.3.
On Thursday, Apple released a rare supplemental update to OS X Yosemite 10.10.3 that resolves a bug in a video driver that was causing some Mac owners to report startup issues or even full-blown kernel panics "when running certain apps that capture video," said the company. Users were reported longer-than-normal startup times or crashes. Not fixed by the new update are scattered reports of problems opening large JPEG files using Preview of QuickLook, but this is again not a universal issue.
Alongside bug fixes and other improvements, Apple has patched a longstanding security flaw which could give users with physical access to a machine root privileges, regardless of assigned permissions. The flaw, indexed as CVE-2015-1130, was reported to Apple in October of 2014, but Apple requested that it be not publicly disclosed until patched due to the "substantial amount of changes" required to fix.
