It is vitally important that you back up your Mac. Whether you do so locally using Time Machine, sending it to a cloud service, or installing a duplicate creation program (or all three). There is nothing more important than backing up your computer in case an unfortunate event happens so you don't lose your precious data.
One of the easiest methods is locally, using Time Machine. Another is by backing up your data via a cloud-based service, like Backblaze or CrashPlan. Here, we're going to explain how to clone your Mac using a program like SuperDuper! or Carbon Copy Cloner.
The difference between cloning and using Time Machine
Local backups through Time Machine, cloud-based backups, and clones all serve a great purpose to keep your data safe in case of an unfortunate even that renders your Mac useless (even temporarily). The thing that makes cloning different is that you can create a bootable copy of your entire hard drive, which means you can access everything on one Mac through another simply by exporting it to an external drive, connecting the drive to the other Mac, and then selecting it from the Startup menu.
Clones are great to have around if, for example, you have to take your Mac in for repairs, but still need to continue working while it's out. You can use the cloned copy while it's in the shop.
Most cloning programs have additional features that include the ability to make regularly scheduled backups. This is ideal since, if something happens to your computer, you aren't necessarily going to want to restore from a year-old backup. I highly recommend investing in these additional features if they are offered with the cloning program you are using (for example, SuperDuper! is free to clone, but costs a licensing fee of $28 for scheduling, smart updates, sandboxes, and scripting).
Before you start
Before you get started, make sure you have an external hard drive with enough storage to fit everything on your Mac. The smartest solution is to use a portable hard drive.
You'll also need to download and install your cloning program. I'm using SuperDuper! from Shirt Pocket for this process. Gfortran for mac os high sierra 10 13 1 download. Most cloning programs operate pretty much the same. They will always have a detailed how-to guide to walk you through the steps.

We are really sorry that M4VGear doen't support macOS High Sierra or above now. Our developers are working hard to fix this problem and it needs to take some time. We would post the latest news about our pragram on our Facebook once we find solutions to fix the issue. Currently, if you only have a Mac computer with macOS High Sierra or above and couldn't find a Windows computer to use our Windows version, you can still try to install and run Mac OS X 10.12 or 10.11 on an external hard drive to make M4VGear work under old version of Mac OSX.
In the following guide, we would show you how to install and run MacOS X 10.12 from an external hard drive as an example.
What You’ll Need:
It's worth noting that you should download the macOS Sierra installer in the App Store under “Previous buys“ or 'previous bought'. Make sure you click “Download” and let it save to your Mac’s hard drive.
Important Tips: If you download and install macOS Sierra through other sources, your Mac might pop out a message that 'Downloading macOS Sierra the way in your Link is Not possible when your have High Sierra installed (because the file System)'. Under “Previous buys“ or 'previous bought' is a working Link where the Download is working .. You can check and install it in parallels successfully.
Step 1: Format External Hard Disk
In order for your external device to function as a startup disk, it must be formatted as Mac OS Extended and employ a GUID partition map. To check what format your drive is using (and change it), you’ll need to launch your Mac’s Disk Utility. Disk Utility can be found in the Applications > Utilities folder or by searching for it using Spotlight.
Once Disk Utility is running, click on your external device in the left-hand pane and check the partition map. In our case, our drive is partitioned using Master Boot Record rather than GUID. So, we definitely need to format it.
WARNING: Before proceeding, understand that formatting will obviously erase everything on your device. If there is anything you want to save, make sure you back it up first!
First, unmount the device.
Once the drive is unmounted, select the full disk in the left sidebar (labeled “UFD 3.0 Silicon” here)—not the sub-disk(s) under it (labeled “Untitled” here)—and click “Erase” in the top row of buttons.

When the operation is complete, you will see the following message. Click “Done” to continue.
Step 2: Install macOS Sierra
When macOS Sierra is downloaded, it is saved in your Applications folder. Double-click the installer to begin.
Click “Continue” to proceed.
Set Up External Hard Drive
“Agree” to the software license agreement.
On the next screen, click “Show All Disks”.
Choose your newly formatted external device and click “Install”.
Enter your system password and hit Enter.
macOS Sierra will now begin installing on your external device. Feel free to grab a cup of coffee or take a shower, because it will take a few minutes.
Before macOS can complete installation, your computer will need to restart. Make sure you save any work and then click “Close Other Applications” to continue.
Once your Mac restarts, it will take about 15 more minutes to finish, and will then boot automatically from the new device.
You will then need to go through the usual macOS setup, including enabling Siri, setting up your time zone, and adding your user account.
Once you’re done with all that, you’ll have a brand new installation of macOS Sierra on your external device.
Make sure you don’t remove or eject your external device while you’re using it, since macOS will periodically need to access it.
