Flashback (Dr_Monkfish) Mac OS

OSX.FlashBack, also known as the Flashback Trojan, Fakeflash, or Trojan BackDoor.Flashback, is a Trojan horse affecting personal computer systems running Mac OS X. The first variant of Flashback was discovered by antivirus company Intego in September 2011. I am having an issue updating my flash player. I uninstalled the previous version of flash player and followed all instructions trying to reinstall. I keep getting a failure message at 55% install. Here is the link to all of the normally requested files: Shared Files - Acrobat.com.

  1. Flashback (dr_monkfish) Mac Os Download
  2. Flashback (dr_monkfish) Mac Os Catalina
  3. Flashback (dr_monkfish) Mac Os X

These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

What you need to create a bootable installer

  • A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB of available storage
  • A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

  • Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
    These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
  • Download: OS X El Capitan
    This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal

  1. Connect the USB flash drive or other volume that you're using for the bootable installer.
  2. Open Terminal, which is in the Utilities folder of your Applications folder.
  3. Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.

Big Sur:*

Catalina:*

Mojave:*

High Sierra:*

El Capitan:

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument and installer path, similar to the way this is done in the command for El Capitan.


After typing the command:

  1. Press Return to enter the command.
  2. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
  3. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased.
  4. After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
  5. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.

Use the bootable installer

Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Apple silicon

  1. Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
  2. Turn on your Mac and continue to hold the power button until you see the startup options window, which shows your bootable volumes.
  3. Select the volume containing the bootable installer, then click Continue.
  4. When the macOS installer opens, follow the onscreen instructions.

Intel processor

  1. Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
  2. Press and hold the Option (Alt) ⌥ key immediately after turning on or restarting your Mac.
  3. Release the Option key when you see a dark screen showing your bootable volumes.
  4. Select the volume containing the bootable installer. Then click the up arrow or press Return.
    If you can't start up from the bootable installer, make sure that the External Boot setting in Startup Security Utility is set to allow booting from external media.
  5. Choose your language, if prompted.
  6. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

A bootable installer doesn't download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model.

For information about the createinstallmedia command and the arguments you can use with it, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:

In today’s technology, if you buy a USB hard drive, you can just simply use it directly using your Mac. However, there are instances that not unless that your flash drive is build to use for your Mac, you will not be able to format it.

Why is this so? The answer to this is because most of the computers actually run on Windows and they actually use a different file format which is known to be the Fat32.

Those drives that are formatted in Fat32 can be used in your Mac for reading and writing but there might be an instance that you might experience some trouble once that you use your macOS native format.

So, in case that you have a flash drive that is formatted into Fat32 or any type of format rather than having a Mac OS Extended or AFPS, then we are going to show you in this article how you could possibly format your flash drive using your Mac.

Part 1: How To Format Flash Drive On Mac

Here are the steps that you need to follow. Do these steps and you will then be able to format your flash drive on your Mac.

Step 1: Go ahead and plug in your flash drive in the USB port on your Mac.

Step 2: After that, go ahead and launch the Finder and click on your flash drive detected by your Mac.

Step 3: See to it that there are no files saved on your flash drive that you no longer need. This is because formatting your flash drive will remove all the data that is stored in it. If there are some files that you want to remain, simply copy these files to your Mac.

Step 4: After getting all the files that you need from your flash drive, go ahead and click on “Applications” and then click “Utilities” and then choose “Disk Utility”.

Step 5: And then, go ahead and click on your flash drive from the sidebar.

Step 6: Once that you have chosen your flash drive, go ahead and click on the “Erase” button located at the toolbar at the top of the window.

Step 7: On the next window that will appear on your screen, go ahead and key in a name for the flash drive that you are formatting from the box next to the “Name” option.

Step 8: And then select a format that you want from the drop-down menu.

Step 9: No, if you have previously stored a data on your flash drive that is highly sensitive, just go ahead and click on the Security Tab.

Step 10: From the security tab, go ahead and choose the level of the security that you want. The more that you move to your right, then the more “passes” the deleted tool will be but it will securely delete your files. However, doing to so will take more of your time to format your flash drive.

Step 11: After that, go ahead and click on the “OK” button and then click on the “Erase” button.

Part 2: Choosing the Right Format

There are formats that you need to choose from depending on the Mac that you are using. If you are using the macOS Sierra or a later version, then you have to options to choose from. One is the AFPS and the other one is the Mac OS Extended. The question now here is that which one should you choose.

You have to keep in mind that once you have formatted your flash drive into AFPS, then those Macs that are running on macOS that is older than the High Sierra will not be able to recognize it.

So, if you would want to use your flash drive on Macs that are running on High Sierra, then you have to choose the Mac OS Extended format.

However, you also have to know that AFPS is actually optimized for SSD or “solid state drive” and it includes flash drives.

That is why if you are going to reformat a flash drive on your Mac, then you should definitely choose the AFPS format as it is known to be the most reliable and faster than the Mac OS Extended. But again, that is if you do not have any plans in using it on a pre-High Sierra course.

And lastly, if in case that you would want to use your flash drive as one of your backup options in Time Machine, then you should definitely have it formatted in Mac OS Extended.

This is because Time Machine does not have the ability yet to backup flash drives that are formatted in AFPS. So, if you are using an AFPS formatted flash drive on Time Machine, it will just ask you to format your flash drive into Mac OS Extended.

Part 3: How To Format Flash Drive To Fat32 On Your Mac

Once that you have a flash drive, then what you would need to do is to have it formatted into Fat32. Why? This is because once that you have formatted your flash drive into Fat32, then you will be able to use it on both Windows and Mac PC when you want to save or transfer files with either of the two.

The Fat32 format can be used – read or write – with both Mac and Windows PC and because of this, it makes the device more versatile.

However, there are some limitations that you should need to know such as an individual file should only have a maximum size of 4GB. But do not worry because there is still something you can do about it and that is by formatting it to exFAT.

The exFAT format will not give any limitations on the file size that you are going to store on your flash drive and you can still use it on both Windows and Macs that are running in Mac OS X Snow Leopard or later version. For you to be able to format your flash drive into Fat32, here is what you need to do.

Step 1: Go ahead and connect your flash drive to your Mac.

Step 2: And then, go to Application and then click on Utilities.

Step 3: After that, go ahead and launch Disk Utility.

Step 4: And then, go ahead and click on your flash drive located at the sidebar in Disk Utility.

Step 5: After that, click on 'Erase' in the Disk Utility window.

Step 6: After that, go ahead and enter the name for the flash drive that you formatted.

Step 7: And then, choose the Format menu and then select MS-DOS (FAT32) or the ExFAT.

Step 8: After that, go ahead and click on the 'Erase' button.

Once that you are done with the provided steps for you, your flash drive will then completely wipe out all the data stored and it is re-formatted into either an ExFAT or FAT32 depending on what you have chosen on the previous steps.

Part 4: Getting Your Mac System Run Fast
