Remove SentinelOne agent from Mac. Because honestly, it doesn't seem to do anything at all. Run as root, best is to do this from a recovery mode, single user mode with writeable filesystem, ...

USE AT OWN RISK

This was only tested on a 'partial' SentinelOne installation on the High Sierra beta, where SentinelOne was never allowed to enable it's kernel extension. (Some things failed while I was messing around with OS betas.)

This script is most likely outdated.

A lot happens in 2+ years, at this point there's a good chance this script will do more harm than good. Read the comments before using!

Walkthrough of what I did to increase performance on my Synology NAS box during an expansion, and afterwards.

Performance on Synology RAIDs

(especially while expanding)

Warning: The exact commands may not match for your particular linux OS / Synology(NAS) device. I had to customize the commands after exploring my particular system's setup.

If you're new to linux, or this is a new piece of hardware / a new synology device, jump down to the section called "Inspecting a setup"

Export TOTP tokens from Authy

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.
