Clean install High Sierra, what should I partition my drive as?

[pjanoo]

Hi all, searched high and low and can't find an answer to this

I'm going to be clean installing High Sierra on my SSD MacBook Pro next week and I'm unsure what partition format to select when I erase my main volume. Should I select APFS or APFS (Encrypted)? If I kept it as HFS+ and allowed the installer to convert it during setup, which one would the installer pick for me?

Currently my drive is not encrypted with FileVault if it has anything to do with that?

Also, if it does select the encrypted version, do I have to provide a password and if I do will it ask me for it before the operating system begins to load? That happened to me once when I tried FileVault and I hated it!

Thanks,

A very confused mac owner!

You want to format to APFS (not the encrypted option) then install the OS. Then AFTER the install if you want to enable FileVault you can, and it will reboot and encrypt the drive.

When you enable FV this way, it makes some changes to the boot process so it works with FV. If you format encrypted as part of the install, these changes will not get made and you will have problems.

Aah thank you very much, unsure whether to enable FileVault as I haven't got it enabled currently, think I'll just stick with APFS unencrypted. I'll also be installing on a third party SSD so might hold off on enabling TRIM until they iron out the boot issues people are having.

Thanks for your help!
