How to partition a hard drive in OS X using Core Storage

HardDriveIconXWhen you set up an external drive for use with your Mac, you may wish to partition it for various uses. For instance, you might want to isolate automatic Time Machine backups from manual ones. The classic way to do this on a single drive is to use Disk Utility to partition it, where you split the drive into two or more logical volumes that the system sees as separate file systems. Since OS X supports Apple’s CoreStorage volume management technology, if you wish to do this then you can do so via classic partitioning, as well as through CoreStorage. Continue reading

Enable a power charging indicator sound on your MacBook when plugged in

SoundIconXFor Mac systems with Magsafe adapters, wall power status has mostly been identifiable by simply looking at your power adapter connector. In doing so, an indicator light of orange or green will tell you both that you are receiving power, and that you are either charging or are fully charged. There is no default sound to indicate attachment to wall power; however, if you have OS X Yosemite installed and are keeping your system up to date, then you have the option to enable one.

Fix OS X hanging at bootup after installing 10.10.3

YosemiteInstallerIconXAfter installing OS X 10.10.3, you will find your Mac undergo the standard restart that is part of the update process, but then see it hang up as OS X loads, leaving you with a gray screen. This is likely happening because because of some changes made to Apple’s FileVault full disk encryption routine.

Along with the 10.10.3 update, Apple issued an update for the OS X Recovery system in Yosemite, which will adjust some of the contents of the hidden recovery partition. This partition is used for unlocking your boot drive at startup, and it appears a problem with the update for some people has caused the drive to improperly unlock the drive. Continue reading

How to fix kernel panics after installing OS X updates

PanicReporterIconXKernel panics in OS X occur primarily because your Mac has faulty or incompatible hardware, or because you are using incompatible or poorly written kernel extension drivers. With either of these situations, the core system software component called the “kernel” may run into a fault from which it cannot recover, which will bring down the entire system. Kernel panics are relatively rare in OS X, but may occur if a piece of hardware has gone bad, or you introduce a bug by updating system software or third-party kernel extensions. If this happens, there are usually a couple of quick approaches you can take to overcome the issue. Continue reading

Latest OS X security updates fix ‘Rootpipe’ vulnerability

SecurityIconXOne recent security flaw in Apple’s Mac OS platform that gained some press recently was the Rootpipe vulnerability, where security researcher Emil Kvarnhammer found a method of hacking a Mac that could bypass OS X’s security and allow the hacker to gain full administrative control of the system. This issue, which took advantage of faulty entitlements for XPC processes (small tools launched on the behalf of an application to take on workloads and spread the risk of a crash from affecting the main application), allowed a developer to break the sandboxing rules in OS X. Continue reading
