If you want to install macOS 10.14 Mojave on your Mac or MacBookIf you want to start from scratch – i.e. with a clean hard drive as if you had just bought a Mac, then this guide will definitely come in handy. We will show you step by step how to perform a clean installation of macOS 10.14 Mojave on your Mac. If you are wondering what a clean installation actually means, it is an installation in which you will lose all your data and settings, but on the other hand you will start with a brand new operating system as if you had just bought a new Mac. Since you will not be overwriting one system with another, this installation should not cause any errors in macOS that could otherwise occur.
I've decided to split this guide into two parts - the first works when you're still running macOS 10.13 High Sierra. The second part deals with the case where you have already updated to macOS 10.14 Mojave and want to perform a clean install.
This is what macOS 10.14 Mojave looks like:

Backup
Backup is the same for both cases – first of all, you need to back up your data that you don't want to lose. You can do this, for example, using a USB flash drive or an external hard drive. If you pay for some cloudelectronic storage (iCloud, Google Play, Dropbox, etc.), you can of course store your data there. It's up to you.
How to clean install macOS 10.14 Mojave from macOS 10.13 High Sierra
If you haven't updated to macOS 10.14 Mojave yet, follow these steps. In App Let the Store download the update to macOS Mojave. Once the update is downloaded, open it – but as soon as the installation wizard appears, exit it immediately. To exit, click on the option in the top menu Install macOS 10.14 and you choose the last option – Exit Install macOS.

Now it is necessary for you to open Finder and moved to the bookmark in the left menu Application. Then find the icon with the name here Install macOS 10.14, right-click on it and choose an option View package contents. Then redirect to Contents -> Resources and find the file named createinstallmedia (don't run it). Now let's open up Terminal (either through Spotlight or using Launchpadu in the Other folder). Type the command below into the terminal and do not press enter for now:
sudo
Then we grab the createinstallmedia file and drag it into Terminal . The command in the terminal will be rewritten to look something like this:
sudo /Applications/Install macOS 10.14.app/Contents/Resources/createinstallmedia
Then add the following text to the command:
-- volume
Then we switch to the active window Finderu and click on Open -> Open folder. Enter in the text field /Volumes and confirm with the key enter. Now you will see all connected drives - both external and internal. Now we will connect to the Mac flash drive, which has miniMinimum capacity 16 GB. As soon as you connect the flash drive, it will appear in the window. Then the flash drive icon we will move to the Terminal (similar to the file above) - the command will look something like this:
sudo /Applications/Install macOS 10.14.app/Contents/Resources/createinstallmedia --volume /Volumes/nameFlashDisk
Now we can confirm the command by enter. The terminal will ask for us password, which we enter and confirm again by enter (the password is written "blindly" in the terminal, so you won't see the asterisks). Then we write the letter "y” and confirm it with enter – using this step we will give the Terminal permission to erase the flash drive and to begin copying data to the flash drive. If you get a message during installation about Xcode, then click the button Not now. When the process is complete, you will see a message in Terminal that everything is done.
Erasing the disk
Restart your Mac (icon Apple logo in the upper left corner -> Restart). Once the screen turns off, press and hold the buttons Command + R until it appears on the Mac screen macOS Utilities – then you can release the keys.

In the left menu of disk utility si click on our disk, on which it is stored operating system. Then click on the icon in the top menu Delete. A new window will appear, in which we write the name of the new disk (the default name is Macintosh HD) and choose the format APFS, which is a new format used by macOS since macOS High Sierra. If for some reason you need the older HFS+ format, select the Extended Mac OS (Journal) option from the menu. Then confirm this choice by clicking on Delete.

You might be wondering why you might want to do a clean install of macOS – and there are a few reasons that I have experienced firsthand. If you are upgrading to Mojave from High Sierra, you are much more likely to encounter bugs during the update. In iOS This procedure is not so necessary, but I really recommend it for macOS, because you avoid unnecessary future problems with the operating system. A clean installation can also be useful if your Mac seems slow or you feel that it is infected - erasing the HDD deletes everything, including viruses, so you will work with a "clean slate". And last but not least, a clean installation is desirable mainly because there has been a change in the macOS file system.
If you thought you could follow the example iOS 12 "pull" back the old backup from Time Machine, then definitely don't do this, as you could bring all the system errors back to your Mac.
or type diskmakerX into Google and create an install USB disk
A USB disk of 8GB is enough.
And why I still don't see Mojave available for download on Air 2015?
Some have it earlier, some later. It appeared to me right after 19 p.m.
And installing on unsupported Macs???

have you tried Or the result? :)
macbook white unibody 2009 full functionality, imac i3 2010 full functionality, see the link people write what and what kind of problem can occur or see the user "dosdude1" on YouTube, he did it all and below the video is the answer to the questions
Just for info, maybe next time write to put a space after each command :-)
Well, the only problem is that I can't log in apphundred :(
Nonsense, everything works on Mac.
So I would probably skip the useless part with Command + R. I would select boot with the option key, select the bootable USB drive with the installer, run Disk Utility... It seems pointless to restart twice.
After turning on the mac, press Alt+command+R - installation of the latest OS
Yes, it is still possible, only yesterday it took a very long time via internet recovery alias Alt+command+R
Otherwise installed and sleeping on MBpro early2015 super. Otherwise Time machine it can backup to an external drive only if it is Mac OS Extended (Journaled)/does not know APFS.
I'm going to reinstall the system (to have a clean) MOJAVE (mini 2014) and then clone to a new SSD that I want to upgrade my Mac to avoid working with a flash drive. So I understand that if I choose APFS, I won't be able toTime Machine?
If I do a clean install and then log in to icloud – all my saved passwords will be loaded Safari? And can't some errors be transferred from icoud to the new system?
Hello, after the installation, the following appears to me - an error occurred during the installation. Can you advise? I would like to take the installation step back and go back to the original version. Thanks for the tips
