- MacOS Extractor, OS X Patcher, and MacPostFactor are apps that guide you through patching and installing OS X El Capitan (10.11), Yosemite (10.10), Mavericks(10.9), or Mountain Lion (10.8) on your older Mac.
- OS X Yosemite brought lots of new features and improvements to the Mac, but it introduced some frustrating Wi-Fi and networking issues, too. Apple still hasn’t fixed the worst one, despite a number of software updates — but there is a simple workaround you can follow to restore connectivity.
- The dock in Mac OS X is intuitive, customizable, and aesthetically pleasing, which is a stark difference from its clunky Windows alternative. In fact, in Windows, it takes both the Start menu and taskbar to accomplish what Apple's dock does—but it doesn't have to be like that. Below, I'll show you how to add an OS X-inspired dock on any PC running Windows XP or higher.
- Oct 22, 2014 Mac OS X brings a slew of features to the classic operating system. Many of the greatest enhancements are found under-hood, while many are flagship features like Continuity.
Mac OS X 10.10 Yosemite Sends User Location and Safari Search Data to Apple October 21, 2014 Swati Khandelwal Apple's latest desktop operating system, known as Mac OS X 10.10 Yosemite, sends location and search data of users without their knowledge to Apple's remote servers by default whenever a user queries the desktop search tool Spotlight.

Code dive You can bypass Apple's space-age security, and gain administrator-level privileges on an OS X Yosemite Mac, using code that fits in a tweet.
Yosemite, aka version 10.10, is the latest stable release of the Mac operating system, so a lot of people are affected by this vulnerability. The security bug can be exploited by a logged-in attacker, or malware on the computer, to gain total unauthorized control of the Mac. The vulnerability is documented here by iOS and OS X guru Stefan Esser.
It's all possible thanks to an environment variable called DYLD_PRINT_TO_FILE that was added in Yosemite. It specifies where in the file system a component of the operating system called the dynamic linker can log error messages.
If the environment variable is abused with a privileged program, an attacker can modify arbitrary files owned by the powerful user account root – files like the one that lists user accounts that are allowed administrator privileges.
Here's the titchy root-level privilege-escalation exploit, devised yesterday by Redditor Numinit:
echo 'echo '$(whoami) ALL=(ALL) NOPASSWD:ALL' >&3' | DYLD_PRINT_TO_FILE=/etc/sudoers newgrp; sudo -s # via reddit: numinit (shorter)
— Stefan Esser (@i0n1c) July 22, 2015
These shell commands run whoami to output your username (eg: vulture) and then tacks 'ALL=(ALL) NOPASSWD:ALL' on the end to form a line like:
It then outputs that line to the file specified by DYLD_PRINT_TO_FILE, which in this case is the list of users who can gain root-level privileges: /etc/sudoers. That line tells OS X that your user account is allowed to gain root privileges without a password.
A privileged program – the root-owned set-uid executable newgrp – is run to provide the root-level access to the sudoers file. Finally, sudo -s is executed to open an interactive command-line shell, which will have root-level privileges for your user account thanks to the update to the sudoers file. From there you can do anything you like; modify documents, install malware, create new users, and so on.
This flaw is present in the latest version of Yosemite, OS X 10.10.4, and the beta, version 10.10.5. If you upgrade to the El Capitan beta (OS X 10.11), you'll be free from the vulnerability as Apple has already fixed it in that preview beta. Once again, if you keep up with Cupertino and install (or buy) the very latest stuff, you'll be rewarded.
Failing that, you can install Esser's SUIDGuard to protect your Mac. 'Apple ships fixes for security in beta versions of future products, but does not fix current versions,' Esser noted. ®
Macs and OS X have a reputation of being the preferred hardware and platform of designers, but quite ironically, there is not a single official Apple computer that comes with an integrated Wacom display. Perhaps Apple considers it unnecessary because Wacom’s Cintiq displays work perfectly with Macs anyway. But there is still a class of people that want to get the best of both worlds, like this latest hack that puts Apple’s latest operating system inside a Cintiq Companion 2 tablet, though not everything is fine and dandy just yet.
The Cintiq Companion 2 is just the latest in Wacom’s attempt to take its Cintiq displays into the realm of independent tablet computers. The tablet runs on an Intel Core processor with 4 to 16 GB of RAM and a 13.3-inch 2560 x 1440 WQHD display. When attached to a PC or a Mac, the Cintiq Companion 2 functions like any other Cintiq display, mirroring the computer’s display. But it can also be used on its own with Windows 8 running inside.
Almost perfect for designers and artists perhaps except for that last part. Some prefer to run Apple’s OS, which is exactly what is being done here. Installing OS X on the tablet is quite involved, but for really enthusiastic users, it might be worth the risk. Unsurprisingly, not everything is working yet. Sleep and the hardware volume rocker are reported to not work. The full-sized SD card reader doesn’t either but the microSD one does. But perhaps the biggest deal breaker is Wi-Fi not working, likely because the tablet’s Wi-Fi chip might not be supported by OS X. Everything else, however, seems to work and the most important part, the stylus and pressure sensitivity, is just fine.
Mac Os X Yosemite Upgrade
While tempting, those attempting such a journey should be aware that none of it is supported by Apple. The very version of OS X Yosemite used might very well be the “Hackintosh” flavor. It isn’t the only option around, though. Modbook is another popular project that goes about it another way. It takes a MacBook or MacBook Pro and takes it apart and slaps on a Wacom digitizer on top to produce the same effect. That said, a complete Modbook Pro costs around $3,000 while the price for a Cintiq Companion 2 is just around $1,300. The Cintiq Companion hack also has the Wacom side buttons that artists are familiar and comfortable with.
