Deleting a Profile from iOS

I have seen a few “infected” iOS devices in the past couple of weeks. Yes, for real. After so many years of being nearly bulletproof to normal malware, the iPhones I’ve worked on were compromised by configuration profiles. To remove the proxy or other malicious settings, the profile has to be deleted.

This Apple KB article details how to remove an app that has installed a profile on your iOS device. Since macOS now uses configuration profiles to ease large deployments, so it’s likely this will become a common threat vector on Apple’s desktop and notebook computers.

TL;DR Instructions

  • Go to Settings > General > Device Management, Profile Management, or Profile & Device Management, then tap on the app’s configuration profile.
  • Tap Delete Profile. If asked, enter your device passcode, then tap Delete.

Running PowerShell on macOS

At work, I have to manage several Office 365 tenants. While many tasks can be completed via the GUI, there are times PowerShell commands are required. That is fine on a Windows 10 computer, since PowerShell is part of the operating system.

However, I prefer to use the company’s iMac. While I was working on an issue with one of our clients, I found an article from Microsoft about using homebrew to install a PowerShell module on macOS!

When I started in IT, I don’t think that would have ever happened.

Automating FTP on the Mac with High Sierra

At work, I was scripting the connection to an FTP server and downloading a website backup.

From articles at Low-End Mac and Mac OS X Hints, this seemed pretty straightforward.

However, the command-line FTP app was removed from recent versions of macOS. A conversation on Stack Exchange explained how to download and install the command-line FTP application.

Now the pieces are in place and that task is automated!
