This guide will show you how to prevent the liberTV SSH client, Dropbear, from being periodically purged. We will move it from its default location in a temporary folder, to a permanent home on the filesystem, allowing it to be invoked without repeated setup in the future.
We will show you various ways to deal with Gatekeeper messages such as “This is an application downloaded from the Internet. Are you sure you want to open it?” and “This application can’t be opened because it was not downloaded from the App Store.”
Today I’ll show you a simple little modification, one which will allow you to display a custom message on your Mac’s login screen. The text can be any custom string of text of your choosing, and could provide essential information to users on shared machines, or simply greet you when you start up the computer.
You may have noticed when opening a Finder window to search for a file that the default setting is to search through the entire Mac. Although this may be precisely what many people want to do, I personally tend to find myself clicking again to refine my search to the current folder.
This guide will outline the simple process to customise the default scope for Finder window searches, so that you no longer have to trawl through your full hard drive for a file which you know is in the folder you’ve already navigated to.
If you’re one of those who love to tweak every little facet of their Mac experience, then this guide is for you. It brings several system information items such as computer name, your current IP address, and your macOS version right to your login screen where they can be easily referenced.
For this modification, all we will need is the Terminal application and a few minutes, so let’s get started!
By default, the behaviour of macOS upon saving a file is to open a simple dialog window, with only a single drop-down menu showing possible save locations. These locations can vary based on the program settings, your most-used save location, or your last-used save location.
Although this is fine for quickly saving documents to common folders such as Documents or Downloads, it is cumbersome to use the drop-down menu when saving regularly to multiple hard drives and previously unused nested folders. Luckily, there is a way to always show a full file browser in the save dialog for more granular control.
Sometimes it is necessary to connect to your mobile device from a computer, for troubleshooting purposes or to use a tool which runs from the computer. For example, tihmstar’s Prometheus suite downgrades your device by sending commands to it from the computer on which it, and the files it uses, are stored. The connection used to do this is called SSH, and is normally provided by the OpenSSH package (or an equivalent client such as Dropbear).
In this guide we will show you how to use SSH to connect to your device from your computer. We will also go through how to change the default passwords on your device, because once you have installed OpenSSH, anyone can log in using the default passwords if you do not change them. This is a major security risk, and so everyone who has OpenSSH installed should follow this procedure.
Many jailbreakers will be familiar with the program TinyUmbrella, which has traditionally been one of the best ways to save SHSH blobs for their iOS devices onto their Macs for safekeeping. What SHSH blobs are, their function, and how to save them is outside the scope of this article, (I will put something together soon on this), but suffice to say that saving these blobs is of some importance to many jailbreakers and that TinyUmbrella has been the go-to application for doing so for a long while.
Whilst the application was updated as recently as August by its creator Semaphore, many Mac users (myself included) have noted that the new version, 9.3.4, gives an error on launch and cannot be used at all. This guide will walk you through the fix to get your umbrella back up again on Mac, so you can carry on wishfully saving those blobs.
The AirDrop file transfer protocol, introduced with Mac OS X Lion and iOS 7, is a fast and convenient way to transfer files between Apple devices. The current version of the service is interoperable between iOS and macOS, but requires both Bluetooth and Wi-Fi to be active in order to work. It also requires Mac OS X Yosemite or newer and a hardware model from 2012 or later.
However, the version of AirDrop that shipped as standard with OS X between 10.7 (Lion) and 10.9 (Mavericks), whilst unable to send files to iOS devices, works without Bluetooth and on Mac models going back as far as 2008. Luckily, alongside the newer version, this legacy mode is still included on all Mac models to date, and as this guide will show, can be modified to have an even broader functionality.
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.
If you’re not familiar with the Quick Look feature on macOS, try selecting a picture, folder, or text document on your computer and pressing the space bar. The rich preview that pops up is Quick Look working its magic. Apple introduced Quick Look in Mac OS X 10.5 Leopard and it has since gained support for many more file types natively, such as Microsoft Office and Adobe Suite documents.
I use it daily and it has become an automatic part of my workflow, a natural response to wanting to inspect a file without waiting for a program to launch and without leaving off what I’m doing.
However, the problem that Quick Look faces is support. It requires a plugin for each file type it can preview, and out-of-the-box only a handful are supplied. More obscure file types are neglected, and display only a blank pane with the file icon, name, size, and date modified. In this guide, I will detail how to add plugins to Quick Look for a richer and more useful preview experience.
