With 10.13's release Apple introduced APFS, which is not readable by older operating systems. An extra step to make 10.13 or later readable from 10.12.6 or older systems would be to make sure the 10.12.6 or older system is to wipe and formatted HFS Extended Journaled before installing 10.12.6 or earlier. And an extra step to make 10.13 or later readable to the 10.12.6 booted system would be to clone backup the newer system, and wipe and reformat the newer system's drive as HFS Extended Journaled. If you are just going to flip booting back and forth, only the first step is needed, as the Option key booting will choose the operating system that is loaded regardless of the drive formatting. When I say wipe, backup your data first. Also note, if you upgrade your libraries to a newer system, such as an Apple Photos library, only the raw photos will be readable by the older system, and not the libraries, tags, albums and favorites. It is better if you downgrade, to have a clone backup of the older system to fall back to, that way avoiding incompatibilities of newer libraries.
Starting with 10.7, on July 20, 2011 downgrading took an entirely new approach:
Apple introduced a restore install utility for Mac OS X 10.7 or later that boots with a command-R. Some macs older than 10.7's releasecould get this utility through this firmware update. As indicated elsewhere on this forum, Macs that had a hardware refresh on or after July 20, 2011,can't boot into 10.6.8 or earlier, though 10.6 server can be installed through virtualization. With each new retail release, the availability in the App Store may vary once you install an older retail online release. You may have to contact App Store billingto get an older online releaes available, or get a refund for an already previously purchased operating system that you go back to download.

A backup is still better than having no backups, as you avoid the pitfalls of older operating systems not being able to handle newer software, or newer software not being able to run on older operating systems. 10.7 was also available for a limited time on an Apple released USB flash drive. You could custom make a USB Flash drive with the installer if you didn't install the operating system the moment the download was complete by copying it to your desktop, and then to the flash drive from the Applications folder. You could also just keep a copy of the installer outside the Applications folder and later clone backup your system to hold onto the installer. Either way the installer was tied to the AppleID that downloaded it and license limitations agreed upon there.10.8's release on July 25, 2012, and 10.9's release on October 22, 2013 likely limited the same hardware refreshes on or after to the same downgrading options. You may not be able to operate drivers or applications that weren't downgraded and removed with the operating system, unless they were compatible with the older operating system. Check with various vendors if uncertain before attempting a downgrade.
You have one more option once backed up, before attempting a full downgrade. Just repartition your hard drive. This option is available in Mac OS X 10.6 and higher as long as your machine supports the older operating system. To repartition your hard drive, read this link

Each partition works like a separate disk.Once you have a second partition that is large enough to install the older operating system, just install it there. Then you can use Apple menu -> System Preferences -> Startup Disk to change your active operating system. Keep in mind each partition can't get over 85% full and that each partition needs to be backed up separately.

Apple also for a limited time sold a USB Flashdrive version of 10.7, that will work on pre-10.7 (July 20, 2011) machines that meet the qualifications on the user tip for 10.7 installation.
For those with machines released after 10.8 (July 25, 2012), only the recovery assistant, may work and it may not be possible to use another 10.8 installer used on a 10.7 machine and transfered to a Flash drive. Of course all this requires any such installer follow the license agreement of the said installer for the number of installations.

Just like in the previous versions of macOS where there certain requirements before download and installation are successful, the new macOS 10.14 comes with requirements and guides to successfully installing running it. Installing and update things mac OS 10.14 is quite a simple task to carry out. But what things to do on a Macbook is quite important to make sure everything works fine before 10.14 installed. Here will list top 10 things you need to do before updating macOS 10.14.
10 Things to Do before Upgrading macOS 10.14
Before upgrading into macOS 10.14, you need to know how to prepare your Mac for macOS 10.14. Here is a list of comprehensive of macOS 10.14 requirements below.
1. Know More about macOS 10.14
This is unarguably the first thing to do before installing any software update. For macOS 10.14, you need to find out exactly what it has to offer and any known issues alongside.
Apple Company releases beta versions of the succeeding OS software version to Apple developers and the public within the months of June to September every year. Bird bait mac os. During this period, you can optimize the opportunity by checking out the features of the macOS 10.14 and get comfortable with having them running on your Mac.
2. Make Sure Your Mac Is in A Healthy Form
You need to confirm your Mac is in good health before trying to install macOS 10.14.

If the drive seems to have errors, you can log off and boot from a different volume, then try to perform repair using the Repair Disk Button.
3. Stay Connected to A Strong And Trusted Network
A strong and trusted network is one important requirement for a glitch-free download of macOS 10.14. A fluctuating network would end up either wasting tons of your time or serving you with incomplete downloads. In the same vein, an untrusted network is very dangerous while downloading the macOS 10.14 so try not to carry out download in a public place as you might not know what lies in there. Home, Office or School networks are the best to stay onto.
4. Check for Enough Disk Space
Apple recommends a disk space of 8GB before installing a macOS. But to be on a safer side, a disk space of 16-20GB should be available on your Mac to ensure safe delivery. Search for irrelevant (heavy or light) files eating up space on your disk drive and trash them.
5. Check to See If Your Mac Spec Suits macOS 10.14
Some Macs have poor specifications or are simply out-dated and therefore cannot carry software updates and Operating Systems. This limitation might be due to low RAM size or just age. Before downloading macOS 10.14, be sure your Mac is supported and can carry the latest OS.

8. Switch To The Latest Version Of macOS 10.13 (High Sierra)
To successfully install macOS 10.14, you may need to have performed the latest update of the macOS 10.13 version. (For instance, if macOS 10.13.5 is the latest update for macOS 10.13 and you are still running on just macOS 10.13. To install the macOS 10.14 version, you'd need to update your macOS 10.13 to macOS 10.13.5). This is a regular process with macOS installation because improvements on stability are included on software updates and there are chances of experiencing glitches while installing a new OS without updating the previous one. You can use the Mac App Store to update macOS 10.13 already installed.
9. Visit The Mac App Store And Download macOS 10.14
Think Before You Go Mac Os X
