- If the installer can't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
- If the installer asks to unlock your disk, enter the password you use to log in to your Mac.

To start the installation process, select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the onscreen instructions.įollow these guidelines during installation: It is only bootable partitions that need to follow the above sequence to avoid trouble.Reinstalling macOS won't remove data from your Mac. For non boot partitions, it is fine to format them as encrypted - e.g.The encryption process is disk intensive so it is best to just let if finish before doing other disk intensive things. You can see the progress of the disk encryption by going to System Preferences -> Security & Privacy -> FileVault. After you enable encryption, wait for the encryption process to finish before installing other software or making big changes.
Perhaps that bug has been fixed now, but I don't know so I would not risk it. I have had issues with disks formatted with multiple partitions when using encryption on one or more of the partitions. I would also recommend to format it the disk as a single partition.If you do it in this sequence then everything works. This can be done near the end of installing Sierra (it prompts you if you want encryption), or after the install is done. Finally, turn on disk encryption (called FileVault).Install macOS Sierra on the fresh, unencrypted disk.Format the target disk "Mac OS Extended (Journaled)" - but not encrypted.
I'm usually installing my Linux systems on fully encrypted disks, thus I am wondering whether this is also possible with macOS Sierra. Is this desired behaviour? How to install macOS on a encrypted, journaled file-system? I was not able to install macOS onto a fully encrypted disk. Now my only option is reboot and remove the encryption via disk utility. MacOS could not be installed on your computer. I entered the password and the process continued until at some point it aborted with the following message: This told me it will check eligibility of my device and due to my encrypted disk it will ask for the password during installation. I quit the disk utility and selected 'Install macOS'.I erased the macOS partition and formatted it with journaled and encrypted file-system.I restarted the system, pressed CMD+R to get into recovery mode and went into disk utility.I just wiped my 500GB disk on my Mac Mini (2011 model) to freshly reinstall macOS Sierra.
