How to hide mounted volumes from your desktop and the Finder
We’ve already covered how to completely prevent partitions from mounting under macOS but, as one iDB reader pointed out, sometimes you want a partition mounted and ready to use but still want the benefit of it not cluttering up your desktop and the Finder sidebar.
The example our reader enquired about was Time Machine, and that really is a perfect case in point. Many people want their Time Machine partition constantly mounted and backing up throughout the day but don’t need it to be visible at all. Finder’s preferences allow for hiding all volumes from the desktop but offer no control on a volume-by-volume basis, and though drives can be manually removed from the Finder window sidebar, this is an inelegant extra step and the drives still show elsewhere.
Luckily, there is a way to leave specific volumes mounted whilst hiding them from both the desktop and the entirety of the Finder in one fell swoop.
How to create blank disk images with Disk Utility
Should you ever find yourself in the need to create blank disk images, OS X’s built-in Disk Utility is your friend. A disk image usually has a .dmg extension and appears, looks and behaves like any ordinary file, with one key exception: launching it prompts OS X to mount the volume on the desktop.
These mountable disk images can be useful in a number of situations. For example, you may want to create blank disk images for storage.
Furthermore, disk images can be used as a virtual disk for software distribution, to burn CDs or DVDs and so forth. In this step-by-step tutorial, you’ll learn how to create blank disk images in Disk Utility, at any size, with optional password protection, formatting options and more.

How to repair disk permissions on Mac
Some Mac hiccups and startup issues can be resolved by repairing disk permissions in OS X. Disk permissions allow your Mac to control what users have access to files and folders on your Mac.
Unfortunately, it’s quite easy to unintentionally mess up disk permissions. In fact, the very act of installing and uninstalling apps on your Mac can over time result in broken permissions.
And when file permissions break, your apps might be allowed to alter each other’s files or even modify read-only system files, which in turn can lead to various permission errors and erroneous behavior in OS X. It is therefore essential that disk permission in OS X are as they are supposed to be.
In this tutorial, I’m going to show you how to verify and fix disk permissions in OS X, which is typically a basic troubleshooting step to fix any software issues your Mac might be plagued with.
