The ohm (symbol: Ω) is the SI derived unit of electrical resistance, named after German physicist Georg Ohm.Various empirically derived standard units for electrical resistance were developed in connection with early telegraphy practice, and the British Association for the Advancement of Science proposed a unit derived from existing units of mass, length and time, and of a convenient scale. There are plenty of reasons for having Ubuntu run on a Mac, including the ability to broaden your technology chops, learn about a different OS, and run one or more OS-specific apps. You may be a Linux developer and realize that the Mac is the best platform to use, or you may simply want to try out Ubuntu.
On June 4 at the WWDC 2018 keynote, Apple® announced major updates to all of its software platforms. One of them is macOS® Mojave, the new version of the operating system for your Mac®.
macOS Mojave will be available to Mac users this fall. But what if you want to look at it earlier?
Immediately after the keynote, the Developer Beta of macOS Mojave became available to members of the Apple Developer program. We expect that by the end of June, it will also be available as a public beta. This will enable many more people to download and install it.
If you’d like to try macOS Mojave, there are several ways:
- You can upgrade the macOS on your Mac. However, Mojave is a beta of an operating system, so this is not a recommended approach.
- You can install it on a separate partition on your Mac. This is a rather geeky approach and requires lots of steps, including repartitioning your drive, booting from the recovery partition, and rebooting several times.
- You can install macOS Mojave on a spare Mac—but how many of us have a spare Mac lying around?
- You can use Parallels Desktop® for Mac and run macOS Mojave in a window alongside other Mac applications. This is a very safe way to try out a beta OS. I’ve done it for years, and I highly recommend it.
Thousands of people use Parallels Desktop to run some version of macOS: Lion, El Capitan, Sierra, or High Sierra. They do it for a number of reasons: to test applications on different macOS versions as developers; to tune it in a sandbox as system admins; to run legacy PowerPC applications using OS X® Snow Leopard; or just to try a new macOS version out of curiosity.
Here’s how you can try Mojave in Parallels Desktop for Mac:
1. Get Parallels Desktop, if you don’t already have it.
- Download Parallels Desktop. You’ll be given a free 14-day trial.
- Install Parallels Desktop—it’s a pretty straightforward process.
If you already have Parallels Desktop on your Mac, make sure it’s version 13.3.2. Earlier versions won’t work with macOS Mojave.
2. Skip the offer to download Windows and you’ll get to the Installation Assistant. (See Figure 1.)
Figure 1_The Installation Assistant window in Parallels Desktop
Scroll through the “Free System” row until you see the “Install macOS” item. (It will name the macOS version you currently have on your Mac. Don’t worry about that.) Select it and click Continue. Parallels Desktop will create a software version of a Mac computer (also called a virtual machine or VM) and automatically boot it from the recovery partition of your Mac.
3. Proceed through the macOS setup: select “Reinstall macOS.” (Don’t worry here either: this will not affect the macOS installed on your Mac.)
macOS will be installed on the virtual disk of the VM that was just created. This is just a file in the Parallels folder in your Documents folder.
4. Now you have a version of macOS running inside a window. Click the yellow triangle in the title bar and install Parallels Tools. Parallels Tools will enhance usability of your virtual computer. You’ll be able to drag and drop files, copy and paste text between systems, and resize windows to change resolution.
5. Now you can upgrade your virtual computer to macOS Mojave. In your new VM, go to the Beta Program page on the Apple site. Sign in and follow the instructions.
6. You will download and run the Beta Access Utility in the virtual computer. Your system will look like Figure 2.

The Install OS X Mojave application will download and launch. Note that this will be about a 5 GB download. Run this application, and soon you’ll have macOS Mojave running in your VM on your Mac.
(Note: As macOS Mojave is not available yet, I’m not 100% sure that steps 5 and 6 are completely accurate. But they are probably very, very close.)
When you have macOS Mojave, it’s time to try its new features: Dark Mode, Dynamic Desktop, new applications and the updated App Store, and more. (See Figure 3.)

Keep in mind that this is a beta version of an operating system, so it might have some issues.
You can help Apple by submitting feedback using Feedback Assistant application. (See Figure 4.)

One interesting thing about macOS Mojave is that it’s likely to be the last macOS to run 32bit applications. This might make it a popular macOS to run in a virtual machine, similar to how Snow Leopard is used to run PowerPC applications via Rosetta.
Parallels Desktop is famous for running Windows applications on Mac. It makes millions of people more productive by running Windows and macOS software side by side on Mac computers. You can also use Parallels Desktop to run many different versions of Linux.
Parallels is excited about the news from Apple and is working hard to get the most out of macOS Mojave in upcoming Parallels Desktop updates.
Important: Known Issues or Limitations
macOS Mojave is a beta release of an operating system. Here are the issues or limitations that we know about today:
- You must use Parallels Desktop 13.3.2 to be able to use macOS Mojave with Parallels Tools. This is a free update to Parallels Desktop 13 for all users.
- Parallels Desktop Lite 1.3.0 and previous versions of Parallels Desktop might experience black screen issues with Mojave guest after the Parallels Tools installation. The macOS Mojave virtual machine will be unusable.
- Known issues of running macOS Mojave in a virtual machine:
- 3D acceleration is not available, so some applications may not work correctly and some graphics artefacts may appear.
- The Parallels Shared Folders icon on the VM desktop may be missing.
- When macOS goes to sleep, the virtual machine gets paused. When you return from pause, there is no mouse cursor. To get the cursor back, just resize the VM window.
- The macOS VM can be switched to Coherence view mode. In Coherence, some application windows may not want to go on top at their selection.
Let us know in the comments about any other issues you experience with the macOS Mojave virtual machine, and let Apple know about your experience with macOS Mojave using its built-in Feedback Assistant (see Figure 4).
Start up from macOS Recovery
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Apple silicon
Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.
Intel processor
Make sure that your Mac has a connection to the internet. Then turn on your Mac and immediately press and hold Command (⌘)-R until you see an Apple logo or other image.
If you're asked to select a user you know the password for, select the user, click Next, then enter their administrator password.
Reinstall macOS
Select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the onscreen instructions.
Follow these guidelines during installation:
- If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
- If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
- If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
- Allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.

After installation is complete, your Mac might restart to a setup assistant. If you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.
Other macOS installation options
When you install macOS from Recovery, you get the current version of the most recently installed macOS, with some exceptions:
V I R A L Mac Os X
- On an Intel-based Mac: If you use Shift-Option-Command-R during startup, you're offered the macOS that came with your Mac, or the closest version still available. If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available.
- If the Mac logic board was just replaced, you may be offered only the latest macOS that is compatible with your Mac. If you just erased your entire startup disk, you may be offered only the macOS that came with your Mac, or the closest version still available.
You can also use these methods to install macOS, if the macOS is compatible with your Mac:
- Use the App Store to download and install the latest macOS.
- Use the App Store or a web browser to download and install an earlier macOS.
- Use a USB flash drive or other secondary volume to create a bootable installer.
