I'm getting ready to sell my MacBook and want to ensure my data is completely unrecoverable. My plan is to encrypt the entire disk first, then reinstall macOS to effectively destroy the encryption key. Since I'm currently using Linux on this laptop, I'm not sure about the easiest way to do this. If I were on Windows, I'd use BitLocker or similar software, but I'm still new to Linux and could use some guidance.

You won’t be able to encrypt the currently running system disk in Linux like you could in Windows. However, what you can do is boot your MacBook from a Linux Live USB and then use Veracrypt or LUKS to encrypt and wipe the disk from there.
Didn't think of livebooting! I’ll definitely try that, thanks!
