  • 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.

  • 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.

  • How to enable HTTP persistent or HTTP keep-alive connection feature for your WordPress website.

    As Wikipedia explains:

    HTTP persistent connection, also called HTTP keep-alive or HTTP connection reuse, involves using a single TCP connection to send and receive multiple HTTP requests/responses instead of opening a new connection for every request/response pair. The newer SPDY protocol uses the same idea and extends it to allow multiple concurrent requests/responses to be multiplexed over a single connection.

    Note: I assume you have adequate knowledge of handling your server and server settings and are well-versed in your field.

    You can put the following code in your .htaceess file, which is in the root of your server’s html folder.
