Mojave is Not Suitable for You? Want to Downgrade?

That mac update deleted everything or missing files after mac update is the worst problem that's ever happened. It has been solved if you follow my steps-by-steps guide. Another formidable problem is the new macOS Mojave 10.14 doesn’t suit you at all. You prefer the previous system macOS High Sierra. In such case, we would recommend you to downgrade macOS Mojave.

Step 2. Click on the apple icon in the top left corner of the screen and choose Restart from the dropdown menu.

Step 3. Press and hold the Option. You would be directed to choose startup disk.

The Bottom Line

General speaking, Time Machine stores your backups on an external hard drive, or on a second internal drive. Even though you can use additional partitions on the main drive, lose the drive and you lost all the backups. So obviously, Time Machine is not the most ideal solution to recover lost files on macOS Mojave.
