Apple has released the first public beta of macOS Mojave, the next major version of its Mac operating system due to launch in the fall. The availability of the public beta means Mac users don't need to be part of the Apple Developer Program to be able to download and test the software. This article shows you how it's done.
Before continuing, a word of warning: We don't recommend installing the macOS Mojave Public Beta on your main Mac. The stability of beta software cannot be guaranteed, as it often contains bugs and issues that have yet to be ironed out, so you're better off using a test machine to avoid any potential data loss.
macOS Mojave is a major update that introduces a range of new features like a Dark Mode, Desktop and Finder improvements, new apps, and a revamped Mac App Store, but not every Mac that can run macOS High Sierra will run macOS Mojave. The full list of compatible Mac models is as follows:
- MacBook (Early 2015 or newer)
- MacBook Air (Mid 2012 or newer)
- MacBook Pro (Mid 2012 or newer)
- Mac mini (Late 2012 or newer)
- iMac (Late 2012 or newer)
- iMac Pro (2017)
- Mac Pro (Late 2013, plus mid 2010 and mid 2012 models with recommended Metal-capable GPU)
Bear in mind that if you decide you want to revert back to your previous setup after testing the Mojave beta, you will need to erase the beta partition and perform a new macOS High Sierra installation.

To install the macOS Mojave public beta, you need to enroll your Mac in the free Apple Beta Software Program.

is incredible how can someone creates a guide on how to install Mac OS beta
and don't even include that basic piece of information
which is in most cases necessary
just to be fair I look at the main post and I didn't found that information
I double check and I still didn't find it
so if I missed I apologies
but I have the one you posted
thanks
there are a few ways to install Mac OS beta
a person can upgrade
a person can clean install on a separate drive
also some people likes to create a bootable pen drive
just in case
always keep that in mind
In my case it went well on my 2012 MBP but not on my MacMini of the same year, this though is not Apple's fault.
I have an SSD and a HD inside, I installed Windows on one but didn't use Bootcamp, instead I Partitioned the disks myself, it's not a corestorage partition and on top of that it had filevault on, I did a High Sierra Install last year and it got hosed, this time I forgot to switch off Filefvault on it and again it got hosed.
But, this was a very special case, I heard few people complaining about a hosed system after installing the beta so you are most likely not affected, and again, this wasn't Apple's fault.
I have the same machine, that is the 13", you might try this:
Go to /Library/Preferences/SystemConfiguration
Make a copy of that folder to the Desktop
Delete the /Library/Preferences/SystemConfiguration Folder
Restart
You will lose all network settings so you have to input them again.
If the above didn't work you can put the folder back and restart again to restore what you had before.
SIP needs to be off for this be able to change anything in the Library Folder.
If you don't know what that is you have to options, ask here again how to disable SIP or just wait for a fix.
I thought CCC wasn't completely compatible with Mojave or APFS just yet.
