On the Linux (Ubuntu.), open Terminal windows and CD to go to your Mac OS virtual machine directory. If you use the Windows operating system, open the CMD windows with Administrator privilege and CD to go to the Mac OS virtual machine directory. May 16, 2018 So you’re running Linux on your computer, maybe Ubuntu, and you have some files with the.dmg extension. In this guide, we’re going to talk about how to open, mount, extract, and otherwise get your files from these pesky DMG images. You could always just extract the files on a Mac, then transfer them back to your Linux machine. Jul 20, 2017 Mac App Store: Click a Button to Install an App. We’re all used to app stores on our phones, but on the desktop they remain an oddity. Still, the Mac App Store is a decent first place to check. Open the store, search for the app you want, and click “Get” then “Download.”. How do I install and set up Linux on a Mac? Linux is an interesting and slightly less well-known operating system - although Macworld's tech-savvy readers are likely to know at least a little.
This in depth guide will take you every step of the way through installing Ubuntu Linux on your Mac, by way of VirtualBox – a free and outstanding program. Using this method you’ll be able to run Ubuntu and macOS at the same time!
Please note: although this guide was initially authored in 2015, it has been updated (late 2019) to be current. The following guide uses Ubuntu 18.04.3 LTS “Bionic Beaver”, but the steps and screenshots are very similar for most versions of Ubuntu.
Using this method to install Ubuntu not only allows you to run it and macOS at the same time, you can really try out Ubuntu – and if you don’t like it – very easily get rid of it. Plus, it will not affect the files in macOS itself at all. None of the data on your Mac is at risk of being deleted or altered. The entire process is actually quite straightforward – and all of the software involved is free – so why not give it a shot :)
Mac Dmg File
- Before you get started, there are a few things that should be noted up front.
- Depending on the speed of your Internet connection, it might take a while to download Ubuntu. During the actual installation process, based on the version of Ubuntu you opt to install – you may have to spend some time downloading updates as well.
- The installation time is about 20 minutes, depending on the speed of your Mac, amount of memory etc. You may want to make yourself a cup of coffee or tea before you start.
- Running both Ubuntu and macOS at the same time will “slow down” your Mac. The more memory you have and the faster your CPU and/or hard drive is, the less you’ll notice it.
Let’s get started!- First up, head over to the Ubuntu download page and download Ubuntu.
- Now you’ll need to download and install VirtualBox. Visit their download page and click the link OS X hosts (which is the current stable version). Once the download has completed, open the .dmg file and run the installer – the installation is as easy as clicking ‘next’ a bunch of times. When installation is done, launch VirtualBox from your Applications folder.
- When VirtualBox opens, click the New button.
- Give your “virtual machine” a name (something descriptive is good, but it doesn’t matter). Make sure the Type: is set to Linux and the Version: is Ubuntu (64 bit). Then click the Continue button.
- Now you’re going to decide how much memory (RAM) you’re going to allocate to Ubuntu when it’s running, and how much to leave for macOS. As illustrated in the screenshot below, my total RAM is 4GB, so I allocated half of it to Ubuntu, and the other half to macOS. The more memory you give to Ubuntu, the faster it will run. The drawback is that macOS will have less to use while Ubuntu is running. At a minimum, give Ubuntu at 1GB (1024MB) of RAM. When you’ve decided how much memory (RAM) to give Ubuntu, click the Continue button.
- On the Hard drive screen, select Create a virtual hard drive now and then click Create.
- Now select VDI (VirtualBox Disk Image) and click Continue
- Select Dynamically allocated and yep – you guessed it – click Continue
- Use the “slider” to determine the size you want to make the “hard drive” for Ubuntu. At a minimum, you’ll want to select 6GB – and that will not allow for you to install many programs, let alone store files etc. Keep in mind that because you selected “Dynamically allocated” in the previous step, that does not mean that VirtualBox is going to take up that space right away. It means that as Ubuntu needs more space, it will allow the “hard drive” to increase up to whatever size you set at this step.As illustrated in the screenshot below, I opted to give Ubuntu 10GB. That’s enough for the installation and to install quite a few programs. Since I won’t be “storing” many files in Ubuntu (movies, pictures, music etc) – 10GB will suit my needs. Plus, I have a small hard drive on my MacBook Air. If you have a big hard drive, you might as well allocate more rather than less, again – the space won’t be used until it’s needed. After you’ve made your selection, click Create.
- Almost time to install Ubuntu! Click the Start button.
- If you’re using macOS 10.15 (Catalina) or later, you’re going to need to ‘allow’ Virtualbox to receive keystrokes from any application (which is completely safe). Click the Open System Preferences button.
- Click the ‘lock’ icon in the bottom left corner of the screen. After entering your password, place a check in the box next to the Virtualbox item in the list.
- Click Later when prompted.
- Back in Virtualbox you’ll be prompted to locate a file. Click the “folder” icon next to menu that says Empty (see screenshot below).
- Again, if you’re using macOS 10.15 or later, you’ll be prompted to grant permission for Virtualbox to access a folder. Click OK. You may be prompted to do this several more times – just click OK each time.
- Navigate to the Ubuntu .iso file that you downloaded all the way back in step #1. Select it, and click Open
- Now click Start
- Finally! Click Install Ubuntu
- Select your keyboard layout and preferred language then click Continue
- Make sure to place a check in both of the boxes – Download updates while installing Ubuntu and Install third-party software for graphics and Wi-Fi hardware and additional media formats – then click the Continue button.
- Select Erase disk and install Ubuntu. NOTE: this is not going to ‘wipe out’ or erase any data in macOS. None. It is safe to click Install Now, so do just that.
- Click Continue
- When prompted, select your Time Zone and then click Continue
- Fill in each field with the required information. When you’re done, Continue
- Now it’s time to sit back and relax with that cup of coffee or tea. This may take a bit.
- Yay! It’s done! Click Restart Now
- Hit Enter (the ‘return’ key on your keyboard) when prompted.
- And you’ll boot into Ubuntu! Enter your password when prompted.
- Welcome to the Ubuntu Desktop! At this point you should be connected to the Internet and completely ready to go – have fun!

UNetbootin for Mac OS X can be used to automate the process of extracting the Ubuntu ISO file to USB, and making the USB drive bootable. The resulting USB drive, however, can be booted on PCs only. If attempting to make a USB drive that can be booted from a Mac, follow the instructions below.

We would encourage Mac users to download Ubuntu Desktop Edition by burning a CD for the time being. But if you would prefer to use a USB, please follow the instructions below.
Note: this procedure requires an .img file that you will be required to create from the .iso file you download.
TIP: Drag and Drop a file from Finder to Terminal to 'paste' the full path without typing and risking type errors.
- Download the desired file
- Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight)
- Convert the .iso file to .img using the convert option of hdiutil
- Note: OS X tends to put the .dmg ending on the output file automatically.
- Run to get the current list of devices
- Insert your flash media
- Run again and determine the device node assigned to your flash media (e.g. /dev/disk2)
- Run(replace N with the disk number from the last command; in the previous example, N would be 2)
- If you see the error 'Unmount of diskN failed: at least one volume could not be unmounted', start Disk Utility.app and unmount the volume (don't eject).
- Execute (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg).
- Using /dev/rdisk instead of /dev/disk may be faster.
- If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.
- If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start Disk Utility.app and unmount the volume (don't eject).
- Run and remove your flash media when the command completes
- Restart your Mac and press alt while the Mac is restarting to choose the USB-Stick
Please notice: While all of the info and above commands are executed properly on a MacBook Air 3,2 (that is the 2010 version 13' version of the Air) the end result will not produce a bootable USB device, at least not with the image for Ubuntu 10.10 64-bit. When booting of the USB device the following message or something similar will appear: 'Missing operating system' and the process is auto-magically halted.
To get the USB device (e.g. a USB stick) to show up at all in the boot menu you also may have to reboot/turn on/off the computer a couple of times and also resync the partition tables using rEFIt. After doing this the USB should then appear as a bootable device while holding in the alt or c key when you are rebooting the computer. Notice that both the computers built in bootloader and rEFIt will identify the USB device as a Windows device, but that's not a problem and expected.
A workaround to the-usb-device-is-not-booting-problem is to:
Install Mac Dmg On Ubuntu Download
- Install rEFIt.
- Create a bootable start disk using Ubuntu and a USB stick.
- Create a separate partition on the Airs HD.
- dd the whole USB stick to that partition.
- Resync with rEFIt. Turn power off and on.
- Select Pingo/Windows logo: Install should start. (Here you might want to press F6 to change parameters, e.g. use nomodeset)

Alternatively, burning a CD and installing via an external CD-drive will work fine on the Macbook Air 3,2.
