Creating a Bootable Kali USB Drive on OS X

OS X is based on UNIX, so creating a bootable Kali Linux USB drive in an OS X environment is similar to doing it on Linux. Once you’ve downloaded and verified your chosen Kali ISO file, you use dd to copy it over to your USB stick.

WARNING: Although the process of imaging Kali on a USB drive is very easy, you can just as easily overwrite a disk drive you didn’t intend to with dd if you do not understand what you are doing, or if you specify an incorrect output path. Double-check what you’re doing before you do it, it’ll be too late afterwards.

Consider yourself warned.

Without the USB drive plugged into the system, open a Terminal window, and type the command diskutil list at the command prompt.
You will get a list of the device paths (looking like /dev/disk0, /dev/disk1, etc.) of the disks mounted on your system, along with information on the partitions on each of the disks.
Plug in your USB device to your Apple computer’s USB port and run the command diskutil list a second time. Your USB drive’s path will most likely be the last one. In any case, it will be one which wasn’t present before. In this example, you can see that there is now a /dev/disk6 which wasn’t previously present.
Unmount the drive (assuming, for this example, the USB stick is /dev/disk6 — do not simply copy this, verify the correct path on your own system!):

diskutil unmount /dev/disk6

Proceed to (carefully!) image the Kali ISO file on the USB device. The following command assumes that your USB drive is on the path /dev/disk6, and you’re in the same directory with your Kali Linux ISO, which is named “kali-linux-1.0.9a-amd64.iso”:

sudo dd if=kali-linux-1.0.9a-amd64.iso of=/dev/disk6 bs=1m

Note: Increasing the blocksize (bs) will speed up the write progress, but will also increase the chances of creating a bad USB stick. Using the given value on OS X has produced reliable images consistently.

Imaging the USB drive can take a good amount of time, over half an hour is not unusual, as the sample output below shows. Be patient!

The dd command provides no feedback until it’s completed, but if your drive has an access indicator, you’ll probably see it flickering from time to time. The time to dd the image across will depend on the speed of the system used, USB drive itself, and USB port it’s inserted into. Once dd has finished imaging the drive, it will output something that looks like this:

2911+1 records in

2911+1 records out

3053371392 bytes transferred in 2151.132182 secs (1419425 bytes/sec)

And that’s it! You can now boot into a Kali Live / Installer environment using the USB device.

To boot from an alternate drive on an OS X system, bring up the boot menu by pressing the Option key immediately after powering on the device and select the drive you want to use.

You got a beautiful new iPhone and it was working great all the while. All of a sudden, it begins to shut off. Not once, not twice but number of times. That’s when it dawns on you that you’re in serious trouble. What’s the first thing you do?

Of course, head to the Apple Store and get the damn thing replaced.

A New iPhone keeps Restarting?

If you got a new iPhone recently and are eligible for replacement without burning a hole in your pocket, the first thing that you do when you are stuck with an iPhone that keeps rebooting, shutting off or freezing is to head to the store and see if you can get it replaced.

Older Models, Out of Replacement Period etc.

For the rest of the crowd that isn’t as lucky, continue reading the article.

My iPhone keeps restarting! What do I do?

We noted that this problem occurs predominantly in bit older iPhones i.e. iPhone 4s, 5, 5c, 5s models that upgrade to iOS 8 or later. Many readers also reported that iPhone 6 and 6 Plus reboot randomly after upgrading to iOS 9. My first reaction was – must be a hardware-software incompatibility issue. But wait. Apple isn’t Android. They know what they’re doing and iPhone 4s does run iOS 8 smoothly.

Well, that’s not the point anyway. We’re trying to fix an issue here so here are the ways, in which you can try to fix your iPhone that keeps shutting off, restarting or freezing.

Turn ON/OFF Cellular: As strange and absolutely impossible as it sounds, I’ve seen people get this issue sorted out by turning off their cellular data and then turning it on again. Arguably, this doesn’t work everywhere. But since this is the most simplest thing you can try, you should begin here. Don’t believe me? Take a look at this. To do so go to settings → Cellular/Mobile → Turn On/Off Mobile Data.

Reboot iPhone: To reboot your iPhone, hold the power button and home button simultaneously for a few seconds. The Apple logo will appear on the screen and your iPhone is rebooted.

Reset iPhone: To reset your iPhone, go to Settings → General → Reset → Reset All Settings.

Faulty App: No matter how strong and protected the App Store is said to be, there are apps that aren’t really good for the health of your iPhone. One of these, possibly, could be ruining your iPhone experience. Did you download any new app that triggered the issue? It doesn’t matter if it’s a popular app or an app that no one has ever heard of. Just try deleting it.

Delete the app → Reboot your iPhone → Sync with iTunes and see if this sorts the issue.

Restore From An Old Backup: No luck yet? Try this method (it’s tougher if you’ve got an iPhone that keeps restarting too often). Connect your iPhone to iTunes on the system and then restore from an old backup. In case you got lucky, things will be back to normal.

Recovery Mode + Restore: This could be the best possible solution you could ask for. Again, it’s tougher to implement if your iPhone keeps shutting off or rebooting every two-three minutes.

What you do is:

Hold down the power and home button till the screen goes blank.
Next, connect to iTunes. It will “detect” the iPhone in “recovery mode.”
You can only restore now so restore your iPhone.

If things went well, you’ll have an iPhone that’s ready to be setup. You’ll have to try setting it as new because you don’t want to get the old problem again.

Use ReiBoot

You can go for this option without losing your data on your iPhone; this option can bring your iPhone back to normalcy. All you need to do is to download this free ReiBoot on MacBook and follow some simple steps:

Download ReiBoot (Mac | Windows)

Connect your iPhone that is trapped in reboot loop problem to your computer via a USB cable. Run ReiBoot. In the Interface, click “Enter Recovery Mode” to put iPhone into recovery mode.

Once ReiBoot puts your iPhone into recovery mode, click “Exit Recovery Mode” and ReiBoot will force your iPhone to restart. Wait for a few seconds and you can see your iPhone reboot to normal.

Replace iPhone Battery: Battery, sometimes, could play a culprit. When every above option fails to give any result, you can go for the replacement of your iPhone battery.

Nothing worked! I can’t really discount this possibility. One usually tries a lot of things before coming to the sober realization that it could be a really serious issue. One that needs you to take the device to the Apple Store, after all.
