How to write a disk image file to an SD card using the command line on a Mac or Linux

How to write a disk image file to an SD card using the command line on a Mac or Linux
Do I need to write a disk image file to the SD card? This will help make the command "dd" for the command line. This handy command works not only on the Mac, but also on computers with Linux, and you do not need to download anything else.
This method is suitable for advanced users who are familiar with the command line. Otherwise, we recommend using a special program, like EtcherIf you have the necessary skills, use the command "dd".

How to write down. img file to SD card via command line

First, start the Terminal program, which is located in the Utilities folder. Then put the file where it will be easy to find.
Issue the following command:
diskutil list
Find the SD card in the diskutil list and write down the rdisk number of this card. Later it will need to be used in the command along with the name of the disk image file.
Then use the following command:
sudo dd if = StartFile.img of = / dev / rdiskOMER bs = 1m
Replace the text "Name of the File" with the name itself, and "rdisk" with the number obtained from the list.
Press return (enter) and enter the administrator password to start recording. This may take some time depending on the file size and the speed of the card.
For example, if the file name looks like "RaspberryPiCustom.img" and the disk number is "/ dev / rdisk4", the command will look like this:
sudo dd if = RaspberryPiCustom.img of = / dev / rdisk4 bs = 1m
Everything is simple enough, so you should not have any difficulties.

How to sort notes on iPhone and iPad by name or date

How to sort notes on iPhone and iPad by name or date

The standard Notes application in iOS is a popular way to record and save various information, leave sketches, merge images into collections, safely store passwords and much more.
By default, notes are sorted by the modification date, but you can change the sorting method. They can be sorted by date of the change, by creation date or by name.
You might have thought that the sorting is configured in the Notes application itself, but in fact, the option needs to be changed in the Settings application. Below we will describe how this is done.

How to sort notes

  1. Open Settings and go to the Notes section.
  2. Scroll down to the "Preview" section and press "Sort".
  3. Choose one of three options:
  • By date of change - the default setting, at the top will be recently updated notes.
  • By creation date - recently created notes will be displayed at the top.
  • By title - the notes will be displayed in alphabetical order.
4. Exit the Settings.
It is possible that in future versions of iOS the sorting setting will be transferred to the Notes application itself, but for now, you need to go to Settings or use the search by notes.

How to recover lost data on iPhone and iPad using iMyFone D-Back

How to recover lost data on iPhone and iPad using iMyFone D-Back
iMyFone D-Back is a program that allows you to easily and quickly recover lost or deleted data on iPhone, iPad and iPod touch.
The program has 4 data recovery modes: recovery from the iOS device itself, recovery from a copy of iTunes, recovery from a copy of iCloud and Smart Recovery mode. iMyFone D-Back can recover more than 20 types of data, including: WhatsApp, WeChat, Kik dialogs, photos, messages, contacts, notes, etc. Moreover, the program allows to solve various iOS errors without data loss.
iMyFone D-Back is fully compatible with iOS 11 and with older versions of the system, starting with iOS 7, as well as with the iPhone X and iPhone 8/8 Plus. Sounds like a program for Windows 10/8/7. You can purchase it by selecting the most suitable subscription, or download a trial version.
The recovery process is very easy. You just need to connect your device to the computer, select the appropriate mode and start the recovery. And the recovery time in iMyFone D-Back is much shorter than in similar programs. Below is a visual diagram with a time ratio.
Data can be recovered not only if you accidentally deleted it, but also when errors occur with the system, after virus attacks, when the device was stolen, etc. It is very easy to use the program. Below we will describe in detail how the most convenient mode works.

How to use the Smart Recovery mode

Step 1: Connect your device with iOS to your computer.
Step 2: Run the iMyFone D-Back program.
Step 3: Select the Smart Recovery mode from the menu on the left.
Step 4: Choose how exactly the data was lost. Among the options: accidental deletion, reset / jailbreak / iOS update, device locking due to a forgotten password, loss or damage to the device and system errors.
Step 5: Scan the device and restore the data.
Scanning will be automatic. iMyFone D-Back can recover data from the devices themselves, as well as from copies of iTunes and iCloud. If you know exactly where the data you want is, you can select the mode that corresponds to each of the repositories. The principle of recovery will be exactly the same.

How to recover deleted photos and videos from iOS

Now let's show on a concrete example. We will restore photos and videos that were stored on the device itself, and were accidentally deleted.
To do this, open the program, select "Recover from iOS Device" on the left, and then mark the type of data to be restored on the page. In our case, this is just a photo and video. Then click "Next".
After that, the program should detect your device. When the icon appears on the screen, press "Scan".
The scanning process will take some time. Be patient. When the scan finishes, you will see all available remote videos and photos. Check the boxes and click "Recover".
Everything is extremely simple. Now you can not worry about data loss and easily restore any content.

How to return "Save As" in the menu on the Mac

How to return "Save As" in the menu on the Mac
Several years ago, Apple decided to hide the "Save As" option in the "File" menu of all Mac programs. This was done in order to simplify the use of the device for ordinary users. While this does not bother most people, advanced users still prefer the Save As command.
In this article, we describe three ways to use the Save As command. Consider two different keyboard shortcuts, and also find out how to return an option in the "File" menu.

Temporary solution

If you do not need to regularly use the "Save As" option, it's easiest to temporarily turn it on only when you need it.
In any program on the Mac, click the File menu , and then hold down the Option key on the keyboard.
You will see that the option "Duplicate" has changed to "Save As". Now just click on the option and select the desired format and save location.

Keyboard shortcut

As you can see in the screenshot above, the Option key not only displayed the "Save As" option, but also the quick keyboard shortcut responsible for the command.
In any document, simply hold down the Option Shift Command S keys to instantly activate the command, opening the window with the choice of format and save location.
This solution is more convenient than the first, but remembering keyboard shortcuts is not easy for everyone.

Constant solution

The final and permanent solution is to create a special keyboard shortcut. This will return the "Save As" option in the "File" menu, so that the combination itself does not have to be memorized.
1)  Go to the Apple menu > System Preferences ...> Keyboard.
2)  Click the Keyboard Shortcuts tab  .
3)  On the left menu, click  Program Key Shortcuts .
4)  Click the + icon  .
5)  Make sure that All Programs is selected in the secondary menu  .
6)  Enter "Save As ..." in the text string. Do not forget about the ellipsis, because this is important. 
7)  In the combination section, hold down Shift + Option + Command + S at the same time. Or you can come up with another keyboard shortcut that you will be easier to remember. However, make sure that it does not coincide with any other standard combination. We recommend using the combination Shift + Option + Command + S.
8)  Click  Add .
Now the "Save As" option will be displayed again in the "File" menu of all programs.

How to take screenshots of any menu on a Mac


Sometimes you need to make a screenshot of only one menu on the Mac without the other elements of the interface.
Of course, you can just take a screenshot of the whole screen and cut out the menu from it. Or you can use a special keyboard shortcut that will make the process easier and faster. Today we will consider both options.
macOS supports the following key combinations for screenshots:
  • Command ( ⌘ ) -Shift ( ⇧ ) -3 : screenshot of the whole screen
  • Command ( ⌘ ) -Shift ( ⇧ ) -4 : screenshot of the screen part

How to make a screenshot of the menu with the title

This can be done in two ways:
  • Take a screenshot of the entire screen and cut out the right part.
  • Take a screenshot of the screen with the menu.

Screenshot full screen

1)  Click on the  menu of  any program to open it.
2)  Select the desired item, if necessary. 
3)  Hold  Command ⌘ ) - Shift ⇧ ) -3  on the keyboard.
The screenshot will be saved in PNG format on your desktop.
Double-click the file to open it in the Viewer.
You can also open the file in any editor by selecting Open with . To crop unwanted parts from the screenshot, drag the edges of the Preview program, and then press Command ⌘ ) - K .
To save changes, click Command S  or select Export from the File menu. The image can be saved in several formats (JPEG, PDF, PNG, TIFF or OpenEXR).
Now the screenshot consists of one menu and does not include other elements of the screen. In addition, by opening it in Preview, you can mark up the Markup by pressing Command Shift - A.
In addition, it is very convenient to make notes with the free program Lightshot.

Screenshot screenshot screenshot

1)  Click on the  menu  in any program.
2)  Hold down the keyboard  Command ⌘ ) - Shift ⇧ ) -4 .
3)  The cursor icon changes. Hold down the mouse button and drag the cursor to select only the menu.
4)  Release the mouse button to save the screenshot of the selected part of the screen. To cancel the action without saving the screenshot, press the Escape key ⎋ ).
Tip:  If you incorrectly selected the start point of the screenshot, without releasing the mouse button, hold down the Spacebar to move the selection area.

How to make a screenshot of the menu without title

1)  Click on the  menu  in the desired program.
2)  Select any menu item, if necessary. 
3)  Hold  Command ⌘ ) - Shift ⇧ ) -4  on the keyboard. The cursor icon changes.
4)  Now press  Spacebar . This will automatically highlight the entire menu behind the camera icon.
5)  Move the icon to the desired menu and click on the mouse button.
This method allows you to take a screenshot of any menu without its title.
Below is an example.
And this is an example of a screenshot made in the first way.
You can easily make screenshots and additional menus. To do this, you just need to open it before you take a screenshot.
If you hold the Spacebar during the screenshot, the selected menu item turns gray instead of blue.
Tip: The  color of the macOS selection can be changed to  System Settings → General .
