TWRP to Magisk

[metropical]

went to OTA Pie.
Bootloader is unlocked, but phone is S-On.
I'd like to TWRP then Magisk.
From Download mode (to install TWRP) I get "command not found" when I enter fastboot flash recovery twrp.img.
What am I doing wrong?

Put twrp.img into directory with adb and fastboot files for Win OS.
Command line must be run from directory where you have adb, fastboot and twrp.img.

In Bootloader or Download I get: command not found for either fastboot devices or fastboot flash recovery /Users/fritz/Downloads/•\ android/twrp-3.4.img.
But adb works fine.
Showing modified and S-On, both of which I don't think I had with Oreo.

I had the wrong fastboot version. TWRP and Magisk are in.
For anyone looking for the right adb & fastboot tools for Mac OS, the link on this page, even though old, is good.
