how to remove “Plugins Button” from Chrome

Update: DetectX v2.75+ now deals correctly with the Plugins Button adware and the instructions below are now redundant.  Just ‘Search’ and ‘Trash All…’ should be sufficient.


If you’re having trouble trying to remove the “Plugins Button” from Chrome because its ‘managed and cannot be removed or disabled’, then follow this procedure.

1. Launch DetectX and do a search. You should see at least 5 items. Do NOT click the Trash button yet.

2. Quit Chrome

3. In Terminal, execute this command* (you’ll need admin privileges)

sudo /usr/bin/profiles -P; sudo -K

If you see a single configuration profile installed with the profileIdentifier ‘org.superduper.extension’, then execute

sudo /usr/bin/profiles -D; sudo -K

to remove it.

Type ‘y’ when prompted.

4. Read the caveats below, and then if appropriate, in DetectX, now click the ‘Trash All…’ button.

5. Relaunch Chrome and check that all is well.

* If you or the machine’s administrator are using ‘Managed Preferences’ and have profiles other than the one mentioned above installed, then do NOT use the ‘-D’ switch in step 3. You’ll need to identify the correct profiles. Use the -P switch to list the installed profiles and only delete the one with ‘org.superduper.extension’ identifier. Likewise, do NOT use the Trash All… feature in DetectX, which will remove the Managed Preferences folder***. Instead, double-click the items in DetectX’s window to open them in Finder and remove them manually that way.

** You’ll need to authorise the deletions when macOS asks you as DetectX doesn’t have the permissions to do that (a safety feature).

*** Note that the ‘Managed Preferences’ folder is a perfectly legitimate folder for server admins that have knowingly installed managed preferences for their users, or for those using Parental Controls. An application update for DetectX will be released shortly to more accurately target this issue rather than flagging the entire Managed Preferences folder.

how to create a bootable macOS installer

If you are preparing to install macOS on multiple computers, one of the things that can make your life simpler (and the waiting shorter) is a bootable USB installer.

The idea of the installer is that you only need to download the macOS from the App Store once. Usually, when you run the installer after downloading it, it’ll delete itself and you have to go through the whole download process again on each machine or disk that you want to install macOS onto. By making a bootable USB drive, you simply plug the drive in to your mac, launch the installer app and tell it where to install the OS. You can repeat this as many times as you like as the installer will remain safe on your USB.

There are various ways to make a bootable USB installer, but they all involve the same process:

1. Download the macOS Installer from the App Store.
2. Run the createinstallmedia command from the Terminal, an AppleScript or a helper app.
3. Reboot your mac, choosing the newly created USB as the startup disk.
4. Run the from the USB.

Step 2 is where the fun is. The createinstallmedia command can be tricky to get right, particularly if you’re not familiar with working on the command line. For those of you that are, follow Apple’s instructions here.

For a little more convenience, I wrapped all that inside an AppleScript which will first ask you for the location of the installer, then ask you to choose the USB target.

For maximum convenience, I also wrote a free little Swift app I’ve dubbed ‘Boot Buddy‘ (cos “Create bootable macOS Installer” just didn’t quite have the right ring to it..!) that will present the whole thing in a neat little user interface. Three clicks, more or less, and you’re done.

Boot Buddy doesn’t require an admin password to install, but you do need to provide an admin password to actually create the bootable installer as the createinstallmedia process has to be run as root. Boot Buddy doesn’t see or use this in any way whatsoever other than to start the createinstallmedia process or to cancel it (if you choose to do so); authorisation is handed off to macOS to take care of.

Boot Buddy requires macOS 10.11 or higher and can create bootable USBs from Mavericks, Yosemite, El Capitan, Sierra and High Sierra installer apps.

Share and enjoy! 🙂
