  • How do you use Disk Utility to partition disks on a Mac?

    Macintosh OSX Disk Utility

    As per Wikipedia:

    Disk Utility is a system utility for performing disk and disk volume-related tasks on the macOS.

    Day-to-day functions supported by Disk Utility are:

    • Creation, conversion, backup, compression and encryption of logical volume images from a wide range of formats read by Disk Utility to .dmg or, for CD/DVD images, .cdr
    • Mounting, unmounting and ejecting external disk volumes
    • Enabling or disabling journaling
    • Verifying a disk’s integrity and repairing it if the disk is damaged
    • Erasing, formatting, partitioning and cloning disks
    • Secure deletion of free space or disk using a “zero out” data, a 7-pass DOD 5220-22 M standard, or a 35-pass Gutmann algorithm
    • Adding or changing partition table between Apple Partition Table, GUID Partition Table and master boot record (MBR)
    • Restoring volumes from Apple Software Restore (ASR) images
    • Checking the S.M.A.R.T. status of a hard disk
    • Disk Utility functions may also be accessed from the OS X command line with the diskutil and hdiutil commands.

    Now, we will learn how to partition disks,

    Important Note:

    • Partitioning a disk erases all the data previously stored on it
    • The disk utility’s partition feature divides the disk into partition sections, which appear on the desktop as separate disks.

    Precaution: Before proceeding, backup all your computer data using Time Machine on a hard drive other than the one you are currently partitioning.

    Here is how to Partition a disk

    Step 01:
    Connect the External Disk to your Mac using a USB / FireWire cable to partition it

    Step 02:
    Locate ‘Disk Utility App in Applications > Utilities

  • How do you change or upgrade the time machine backup hard disk without losing your old backup data?

    Here is how to transfer backups from a current backup drive to a new high-capacity backup drive

    Step 01: First, check the format of your new backup drive

    1. Connect your new backup drive to your Mac.
    2. Open Disk Utility (located in the Utilities folder).
    3. In Disk Utility, select the new drive’s icon to ensure it has a GUID partition and is formatted as Mac OS Extended (Journaled). Reformat it with the Mac OSX Extended (Journaled) option with a GUID partition. At this stage, you can format your new backup drive with Mac OSX Extended (Journaled, Encrypted) to password-protect it and thus safeguard your data. Remember to write down the encryption password you set for your drive this time.

    Step 02: Set permissions on your new backup drive

    1. Open a new Finder window. In the sidebar, click the icon of the latest backup drive.
    2. Choose Get Info from the File menu.
    3. Make sure “Ignore ownership on this volume” is deselected (unchecked) at the bottom of the “Sharing & Permissions” section of the Get Info window.

  • What does the Trust this Computer functionality mean, and what if you accidentally tapped on Don’t Trust this Computer and want to reset it?

    What do trust settings mean to your iOS & macOS device

    When you connect your iPhone, iPad, or iPod touch to a computer for the first time, an alert asks whether you want to trust this computer or not.

    Relationships of Trusted Devices:

    1. Trusted computers can sync with your iOS device, create backups, and access your device’s photos, videos, contacts, and other content.
    2. These computers remain trusted until you change device privacy settings or erase your iOS device.
    3. If you choose not to trust a computer, you block its access to content on your device. You’ll see the trust alert whenever you connect your iOS device to that computer.

  • How to open an Apple macOS app from an unidentified developer.

    If you are like mine, use safe macOS default settings to allow the system to run & open apps only from third-party Identified App Developers.

    You may face a problem with something like this. Your Mac’s Security & Privacy preferences will not allow you to open the app from an unidentified macOS App Developer.

    If you navigate to System Preferences > Security & Privacy > General tab, you will see something like this:

    System-Preferances-Security-and-Privacy-open-anyway

    So, how will you open that particular app blocked by the Security & Privacy Settings?

    Solution 01:
    You can change the settings available in System Preferences > Security & Privacy > General tab under Allow apps downloaded to Anywhere

    Important Note:
    This solution may not be the safest for the health of your operating system security & privacy settings.

  • The complete guide for maintaining and optimising WordPress websites for optimum performance.

    Introduction

    I have been using WordPress for almost more than five years now.

    In the post below, I will explain the step-by-step procedure for hardening, securing, and optimising WordPress for best performance and security.

    So, First things first,

    Introduction to WordPress

    What is WordPress? WordPress is a free and open-source content management system (CMS) based on PHP and MySQL. Its features include a plugin architecture and a template system. As of January 2015, over 23.3% of the top 10 million websites used WordPress. WordPress is also the most popular blogging system on the Web, with more than 60 million websites using it.

    As we know today, WordPress is offered in two different formats: one is managed and hosted by the team at WordPress.com, and the other is self-hosted by the user using a downloadable installable package available at WordPress.org.

    Difference between WordPress.com & WordPress.org

    The following things differentiate WordPress.com and WordPress.org from each other

    1st Difference
    WordPress.com: The user provides the content & website is managed by the team at WordPress.com.
    WordPress.org: Content provided by the User & Managed by the user itself.

  • Leverage browser caching for improved webpage load time performance & speed.

    Introduction:

    To enable browser caching, you need to set expiry dates on certain files. Find your .htaccess file in the root of your domain. You can edit the .htaccess file with Notepad or any text editor. In this file, we will set our caching parameters to tell the browser what types of files to cache over a period of time so that page loading time improves by avoiding or keeping certain files and using browser cache from history.

  • Fix the WordPress.com Jetpack error: ‘Website needs to be publicly accessible to use Jetpack.’

    Your website needs to be publicly accessible to use Jetpack: site_inaccessible
    Error Details: The Jetpack server could not communicate with your site [HTTP 404]. Ask your web host if they allow connections from WordPress.com. If you need further assistance, contact Jetpack Support: http://jetpack.me/support/

  • How to outline the round corners effect in Adobe Illustrator.

    Adobe Illustrator is a full-featured, one-stop solution Vector Illustration program from Adobe, whose birth dates back to 1984.

    Adobe has various advanced and useful features, one of which is (Smart) Effects for vector objects, which are highly editable even after being applied to different objects.

    As stated in Adobe Help Documents, Adobe Illustrator Effects are described as follows:

    Illustrator includes a variety of effects that you can apply to an object, group, or layer to change its characteristics.

    Illustrator CS3 and earlier included effects and filters, but now Illustrator includes only effects (except SVG Filters). The primary difference between a filter and an effect is that a filter modifies an object or layer permanently. Still, an effect and its properties can be changed or removed anytime.

    Once you apply an effect to an object, the effect appears in the Appearance panel. From the Appearance panel, you can edit the effect, move it, duplicate it, delete it, or save it as part of a graphic style. When using an impact, you must expand the object before accessing the new points.

    One of those effects is the round corner. You can apply round corners to your current drawn rectangle and square shapes in your document and edit their value at any time.
