Suggested January 2024 How To View And Access The “Library” Folder In Os X
On your Mac there is a Library folder present inside your Home Folder. For those who are a bit familiar with code, this Library folder is written as ~/Library, which stands for a folder named as Library in the root level of your account’s home folder. This folder actually contains all your personal settings, some application files and also some of your data.
As with all program files of the type, Apple meant for the Library folder to be left alone, but if you’ve been using your Mac for quite a while now, and have needed to delete an application preference file or have grabbed a log to send to a developer, you may have already accessed this folder.
Up to OS X 10.7 Lion, accessing the Library folder was quite simple; all you needed to do is navigate to your Home folder, and from there you could access the Library folder. But from OS X 10.8 onwards, Apple has hidden the Library folder, meaning it won’t show up in your Home folder anymore.
While Apple is somewhat right in its motives to hide the ~/Library folder, a normal user can have plenty of reasons to access the folder, and with Apple’s work of making the folder “invisible,” many can get confused regarding this. Luckily, Apple has only hidden the folder, and we’ll be telling you how to make the folder visible again.
Making the ~/Library Folder Visible in OS X 10.8 Mountain LionIn OS X 10.8 Mountain Lion you can access the aforementioned folder using Finder using the following steps.
1. Open up a new Finder Window, and from the Go menu, select Go to Folder (also accessible by pressing “Command + Shift + G”).
2. In the window that opens, simply type in “~/Library,” without the inverted commas of course, and press Enter.
The folder will automatically open up in front of you.
You can also use Terminal to access the folder.
2. On Terminal, type open ~/Library and press Enter which will open up the folder in Finder.
Making the Folder Visible in OS X 10.9 Mavericks and LaterIf you’re using OS X 10.9 Mavericks or OS X 10.10 Yosemite, you can use both methods detailed above in addition to another easy one:
In the second to last section, the last option will be “Show Library Folder.” Make sure this box is checked. Once it is, you’ll see the Library folder immediately.
In OS X Mavericks/Yosemite or later, you can use this setting at any time to make the folder visible. You will need to use it after some interval, as usual updates should make the folder invisible again.
Again, remember that before you start editing the contents of this folder, you need to make sure you know what you’re doing! Deleting or moving the wrong file(s) inside this folder could cause an application to misbehave, to lose its settings, or even to lose data.
Did the methods detailed above work for you? Let us know in the Comments section below.

How To Disable The Dashboard In Mac Os X
The Dashboard in Mac OS X was first introduced in version 10.4, and can be used to run many useful widgets (ie. calendar, package tracker, weather). Even though it can come in handy for checking quick stats and info, it often goes unused by Mac users.
Since there really isn’t a point in having it running if you’re not going to use it, here’s how you can disable the Dashboard in Mac OS X.
Open Terminal and enter the following commands:
defaultswrite
com.apple.dashboard mcx-disabled-boolean
YESkillall
DockFinder will restart automatically and there will be no more dashboard.
If you ever want to re-enable the Dashboard, enter these commands in Terminal:
defaultswrite
com.apple.dashboard mcx-disabled-boolean
NOkillall
DockAgain, Finder will restart and the Dashboard will be back as it if never left.

How To Change The Mail Font Size In Mac Os X
The default font size in the Mail app for Mac OS X is size 12 for emails and messages that are lacking styling, which tends to be most communications that are sent by email.
If you find the font size in Mail for Mac to be too small, or even too big, you’ll be pleased to know that changing the text size of email messages is quite simple. Not only can you change the font size for the email content itself, but also for other components of an email message, including the sender, recipients, subject line, and even the message list.
While we’re going to focus on changing the actual font size, it should be noted that users can also easily change the font family or face as well. From a readability standpoint, it’s the font size that most users may find improves their Mail app experience.
How to Adjust the Font Size of Mail App in Mac OS XThis can be used to adjust the font sizes in Mail app either down or up, and the process is the same regardless of which version of Mac OS is installed on the Mac.
Open Mail app if you haven’t done so already
Optional but recommended: select / open an email message to see a live preview of the changed mail font size for
Pull down the “Mail” menu and select “Preferences”
Choose the “Fonts & Colors” tab and adjust the following:
Close out of Mail Preferences when satisfied with the change
A change in font size can make a considerable difference in readability in either direction, this is particularly true if a users eyesight isn’t perfect or even if you’re just trying to avoid eyestrain and spend a lot of time sending and receiving emails.
For example, here’s an email message in Mail app for MacOS and Mac OS X with the default font size:
And here’s the same email message in the Mac Mail app with a font size increased to size 18:
While that may look too large for some users, it may be perfect for others, it really depends on user preference, and the screen size of the display in use. This is specific to the actual Mail app in Mac OS X, meaning if your default email client is set to something else, or even to webmail, you’d need to adjust those settings separately. For web mail users like Gmail, Yahoo, and Hotmail, simply increasing the browsers text size with a zoom keystroke is typically sufficient.
This obviously covers the Mac side of things, and remember that iPad and iPhone users can also change the mail text size on iOS to accommodate their preferences.
Keyboard Shortcuts for Increasing & Decreasing Font Size in Mail for MacIt’s worth mentioning that you can also change the font size of emails you are actively composing by using the ‘Format’ menu in Mail app too, and there are two handy keyboard shortcuts for increasing and decreasing Mail font size using the Formats menu:
Command + to increase font size
Command – to decrease font size
You can also access those formatting options from the ‘Format’ menu within Mail app. These keystrokes are found in many other places in Mac OS for increasing and decreasing font size, including Safari, so they may already be familiar to you.

How To Select A Startup Disk In Os X
There may be cases in which you need to boot to a secondary hard drive on your Mac, either to recover a drive, install a new OS or restore some software. Either way, the easiest way to do this on Apple computers is to hold down the “Option” key while booting up your system; however, there may be some constraints.
Selecting a Startup Disk on Macs That Use a Bluetooth KeyboardOn portable Macs, you can start up or reboot your Mac, and simply hold the “Option” key once the screen goes black so that when it reboots it will show you the boot menu. However, this process is a little more specific on Macs that use a Bluetooth keyboard.
If you hold down the key before the Bluetooth keyboard and your Mac boots, your system will prevent it from recognizing the key as pressed. Bluetooth keyboards only start up once the boot chimes sound. To ensure that your Mac goes to the boot menu, only press and hold the “Option” key immediately after hearing your Mac boot sound, not before.
When you’ve opened the boot menu properly, a gray screen will display that will show the available boot volumes, similar to the one above.
If your system is running OS X 10.7 Lion or later, you’ll see the default Macintosh HD partition alongside a Recovery HD volume. However, for systems running 10.6 or earlier, you’ll only see the main boot volume. If you want to boot using a different drive, you can simply attach an external hard drive, flash drive, or an optical disk that contains valid operating systems and when recognized they should appear alongside the current boot options.
Booting from Optical DrivesAdditionally, if your Mac shipped with an optical drive, you can simply boot to a disk in the drive by holding down the “C” key at startup. This “C” key method works both for Macs with CD drives as well as for Macs with DVD drives included. And if you want to use an external USB DVD drive to insert a boot DVD and run it, simply connect it via USB, and the drive should appear in the standard boot menu for access.
Directly Accessing OS X’s Recovery DiskIf your system runs OS X 10.7 or later, you can also boot directly to the recovery drive by holding “Command + R” on startup. Also, most systems shipped after 2010 support Internet Recovery. This can be invoked by holding “Option + Command + R”. The Internet Recovery method will require an Internet connection through which it will download a 650MB recovery image file from Apple.
Note: You should know that selecting an alternative boot disk will only be set for the current boot session. If you want to permanently select a different startup disk in OS X, use the Startup Disk settings that are available in System Preferences.

How To Access A Models Data From A View In Backbone Js
In chúng tôi views are typically associated with a model and have access to the model’s data through the view’s this.model property. To access the data of the model in a view, you can use the get() method on the model, passing in the name of the attribute you wish to retrieve.
Backbone.js is a lightweight JavaScript library that helps to structure and organize client-side chúng tôi provides a model-view-controller (MVC) framework for building web applications. The model represents the data, the view represents the UI, and the controller manages the interactions between the two. This structure allows for a clear separation of concerns and makes it easier to maintain and scale the application.
Backbone.js also provides a set of built-in features such as event handling, routing, and syncing with a server. These features make it easy to create dynamic and interactive web applications without having to build everything from scratch. It can be used in conjunction with other popular JavaScript frameworks such as React and AngularJS to build complex web applications.
Overall, chúng tôi is a powerful tool for building web applications and has a large community of developers who contribute to its development.
Backbone.js ModelsBackbone.js models are the basic building blocks of a chúng tôi application. They represent the data and the state of the application and are used to interact with the server-side data.
A chúng tôi model is a JavaScript object that has a set of attributes and methods that allow it to interact with the data. The attributes represent the data that the model holds, such as the name, age, or email address of a user. The methods allow the model to interact with the data, such as saving, updating, or deleting it.
Backbone.js models are also event-driven, which means that they can trigger events when their data changes. This allows other parts of the application to respond to the changes and update themselves accordingly.
In summary, chúng tôi models are used to represent the data and state of an application, and allow for interaction with the server-side data through attributes and methods, as well as event-driven behavior.
Backbone.js ViewsBackbone.js views are the visual representation of the data stored in a chúng tôi model. They are responsible for rendering the data to the user in a specific format, such as a table or a form.
Accessing Model’s Data from a ViewNow since we have understood what models and views are in chúng tôi it is time to really dive into the code to understand how we can access the data of a particular model from a view in Backbone.js.
ExampleThe following code does the same −
Access Model’s Data var Person = Backbone.Model.extend({ defaults: { name: ‘Rahul Gupta’, age: 26 } }); var PersonView = Backbone.View.extend({ initialize: function(options) { this.model = options.model; this.listenTo(this.model, ‘change’, this.render); }, render: function() { this.$el.html(this.model.get(‘name’) + ‘ ‘ + this.model.get(‘age’)); }, updateName: function() { var newName = prompt(“Enter a new name:”); this.model.set({name: newName}); } }); var person = new Person(); var personView = new PersonView({model: person}); personView.render(); document.write(personView.el.textContent); personView.updateName(); document.write(personView.el.textContent); Understanding the code
In this code snippet −
We have created a model named “Person” with default name and age attributes.
We then created a view named “PersonView” that listens to changes in the model and renders the view accordingly.
We then created an instance of the model and passed it as an option to the view’s constructor.
In the render function of the view, we accessed the name and age attributes of the model using the get method and displayed them on the page.
We also created a function called “updateName” that allows the user to enter a new name and updates the model’s name attribute using the set method.
When the model’s name attribute is updated, the view re-renders itself with the new name.
Mount & Unmount Drives From The Command Line In Mac Os X
You can mount and unmount drives, volumes, and disks from the command line of MacOS and Mac OS X.
This trick works with external USB disks, hard drives, Firewire, Thunderbolt, DVD’s, CD’s, network drives, even USB thumb drives, literally any volume that can be mounted and accessed through the incredibly helpful diskutil command. By using the command line to remount the drive, the entire process can be completed remotely if necessary through SSH, and without ever having to physically disconnect a drive from the Mac. This is infinitely useful for troubleshooting situations, for scripting and automation, and it’s a great trick for those of us who just like to tinker around in Terminal.
How to Unmount a Drive from Command Line on MacLet’s first cover unmounting drives. To do this you’ll need another volume attached or connected to the Mac in some form or another, then launch Terminal to get started (sits in /Applications/Utilities/).
1: List All DrivesThe first thing you’ll need to do is list the connected drives. This will provide a list of all drives that are attached to the Mac, that are either mounted and unmounted, and all of their respective partitions. We are doing this so we can get the drive identifier, which is typically something like disk1s2, or disk2s2, etc
diskutil list
The output will look something like this:
2: Apple_HFS OSXDaily 15.7 GB disk1s2
For the sake of this example, we’ll focus on the attached drive named “OSXDaily”, which happens to be an external USB thumb drive that appears last in the list. Note the identifier for that drive is “disk1s2” and we’ll carry that to the next series of commands to unmount and remount it.
It’s probably worth mentioning that drives will always be located in /dev/ and thus /dev/ will always be prefixed to the identifier.
2: Unmount the Specified DriveStill using the diskutil command, we’ll point it at the drive in question to unmount.
diskutil unmount /dev/disk1s2
This will report back the named volume and location has been unmounted, like so:
Volume OSXDaily on disk1s2 unmounted
That’s all there is to it. You’ll notice the drive is no longer accessible in Finder, but it will still be visible through diskutil from the command line, or the more familiar Disk Utility app in Mac OS X’s GUI.
How to Mount a Drive from the Command Line on MacIf you can unmount a drive, of course you can mount or remount one too. The command sequence is very similar; locate the volume, then mount the drive.
1: Find the Drive to MountIf you already know where the volume is located, you can ignore part 1 and jump straight to part 2, but let’s cover retrieving the volume identifier anyway. This time around we’ll shorten it a bit because we’ll assume we know the name of the drive to mount, thus we only need to locate the identifier. We’ll do this by using grep to shorten the output of the diskutil command like so:
2: Apple_HFS OSXDaily 15.7 GB disk1s2
That output is obviously much shorter than the full output of diskutil list which we showed above.
For this example, the drive “OSXDaily” is still located at /dev/disk1s2 and that’s what we’ll mount.
2: Mount (or Remount) the DriveTo mount (or remount) a drive, we’ll use the same diskutil command with a new flag and inputs like so:
diskutil mount /dev/disk1s2
Using the same examples as elsewhere, here is what the command and the output will look like:
Volume OSXDaily on /dev/disk1s2 mounted
This obviously mounts the drive again, and it will also make the mounted volume visible again in the Mac OS X Finder and to GUI-based apps in the various Open or Save dialog boxes.
How to Unmount & Remount a Drive / Volume in a Single CommandWant to quickly unmount and remount the same volume, essentially power cycling it’s connectivity to the Mac? You can do that in a single command by stringing the two together like so:
Want to quickly unmount and remount the same volume, essentially power cycling it’s connectivity to the Mac? You can do that in a single command by stringing the two together like so:
diskutil unmount /dev/disk1s2;diskutil mount /dev/disk1s2;echo "Remounted Volume"
This would look like the following when executed:
Remounted Volume
If you happened to be watching the volume in the Finder during this process, you would find it to disappear briefly, then reappear almost immediately. The last echo portion is optional but it makes the entire command action even more verbose.
