When 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
After upgrading to OS X 10.10.3, you may find that navigating the Finder can be arduously slow at times, where the contents of folders you open may take a while to display, and otherwise scrolling and navigating may be overall sluggish. If this occurs, then you can likely fix it by clearing some Finder-related cache information from your Mac. Continue reading
For 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. Continue reading
When you are at the login window in OS X, your system should be set to use the default keyboard layout you chose when you initially set up your Mac; however, there may be instances where this layout changes, which in some cases can frustrate your ability to enter your username and password. While you can change your keyboard layout from the login window through the input menu (provided you have it enabled), this should not be required every time you use your Mac. Continue reading
An issue may occur on some Mac systems where after installing the OS X 10.10.3 update, the Finder and other services that report drive space may show an increasing level of available space. This may be accompanied by the Storage tab in the About This Mac window showing your hard drive’s space is being used only for backups.
In general, when this type of oddity appears in the About This Mac window, it suggests your drive’s Spotlight index needs to be rebuilt; however, this issue will likely survive a forced index rebuild. Continue reading
After 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
Kernel 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
One 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
Apple’s new Photos program in OS X 10.10.3 may have difficulty when migrating your old iPhoto library. When it first runs, Photos will create a new library, and do so by migrating from an existing Aperture or iPhoto library, if present. However, there may be a couple of issues where the program will be unable to do so. Continue reading
A few people who have attempted to install the latest OS X 10.10.3 update have found an issue where the update will take a while to install, and then restart only to stall at boot, followed by loading back to OS X 10.10.2. In some cases this may happen repeatedly, suggesting a fault with your Mac’s current setup that is preventing the installation. If you are stuck in this situation, you can overcome the issue through a couple of quick troubleshooting steps. Continue reading
