Tip: Backup Mac data before downgrading macOS or Mac OS X

It's highly recommended for you to back up all important Mac data first before you start downgrading Mac OS to an older system.

You can either choose third-party Mac backup software to back up Mac data to an external hard drive at once or choose Time Machine to back up all wanted data with ease.

Automatically back up all your files with Time Machine, which is built in to your Mac, or choose another backup method. Create a backup. Store files in iCloud. You can also use iCloud and iCloud Drive to store files, such as your photos, documents, and music. Before proceeding, make sure your /.profile contains the lines described above (see 'Your complete /.profile should now look like this:'). Log out, then log back in, so your /.profile takes effect. Try running these commands from the command line: idraw nrngui neurondemo.

Please double-check your Mac's model ID before proceeding (press the Option key then choose Apple Menu System Information). Once you know the model ID, use the My Upgrades feature to find the right drive. If you're still not 100% sure, our sales representatives are happy to help. STEP #2 Make sure you have a way to transfer your data.

Considering data security, it's also highly recommended for you to backup all important data into an external hard drive.

If you prefer to use Time Machine, here are the details:

  • Click 'Finder' > 'Preference'> Check 'Hard disks box' underShow these items on the desktop.
  • Open the backup disk and create a file folder and name it, for example, 'My Backup'.
  • Open the Mac disk and click'Users' file folder > Select all files and data that you want to back up and drag to the My Backup file folder.

Wait for the process to finish. After backing up all data, then you can start to revert macOS with ease. Here, you'll find two methods for you to downgrade macOS without losing data and you can choose either one as a guide.

Bonus Tip: Restore Lost Data after Downgrading macOS/Mac OS X(without backups)

This method is for users who have forgotten to back up important data before downgrading Mac OS. And if you lost data after Mac OS reinstallation or downgrading, here is the solution - to restore lost data after Mac OS X downgrading or reinstallation with powerful Mac data recovery software.

EaseUS Mac data recovery software supports to restore whatever you lost in Mac and it's fully compatible with all Mac OS above 10.8

And if you happen to lost important data after Mac OS downgrading, let EaseUS Data Recovery Wizard for Mac help you out. Three steps will do all jobs.

The name of your macOS user account and the name of your home folder must both be the same. Changing these names does not change or reset the password of your user account.

Because doing this incorrectly could damage your account and prevent you from logging in, you should back up your important data before proceeding.

First rename the home folder

  1. Log out of the account you're renaming, then log in to a different administrator account. (If you don't have another administrator account, you can create one in Users & Groups preferences.)
  2. Open the Users folder on the startup disk. It contains the home folder for each user. To get there, you can choose Go > Go to Folder from the menu bar, then enter /Users.
  3. Rename the user's home folder without using any spaces in the new name. You'll be prompted to enter the administrator name and password that you used to log in. If you're using file sharing to share the home folder, you won't be able to rename it until you stop sharing the folder.

  6. If you want to change the full name associated with your account, update the 'Full name' field as well. It can be any name, and you can use either the full name or the account name to log in to your Mac or make changes that require your name and password.
  7. Click OK, then restart your Mac.
  8. Log in to the renamed account, then verify that your old files and folders are visible and the account is working as expected.
