Sudo Command Not Found Mac Catalina

. Install Homebrew on your Mac. Keep pressing on the Command and Space keys together. Go to the Spotlight option. Enter Terminal in the search bar. Click on the Enter option. Firstly, you have to start installing the Xcode command-line tool by going through the below-mentioned command. Hold Command+R while your Mac powers on to boot into Recovery Mode. From the macOS Utilities window, open Disk Utility. Select your Macintosh HD from the sidebar and click Erase. Fill in a new name for your drive and confirm you want to Erase it. Quit Disk Utility and click Reinstall macOS from the Utilities window. With macOS Catalina, perhaps more significantly, Gatekeeper will also check non-quarantined apps and files for problems. Not just once or twice, but every time you run it. When your Mac detects a problem, it blocks the file, then sends you an alert. If all this sounds fantastic to you, terrific. That's undoubtedly Apple's intent.

Sudo Command Not Found Mac Catalina

Troubleshooting


Problem

To install Rational Performance Tester (RPT) via IBM Installation Manager (IM), the RPT_SETUP archive file is downloaded and extracted first in order to install IM.
Running Install.app in Finder from the RPT_SETUP/InstallerImage_macosx_cocoa_x86_64 folder, as showing in the following screen capture:
An error message is displayed:
This problem is not limited to RPT only, but also applies to other products that use IM for installation.

Cause

The macOS Catalina security restrictions prevent applications not notarized with Apple from installing; the IM files are not notarized and are thus not trusted by Catalina.

Resolving The Problem

Since the problem was found during IM installation for RPT, RPT folder names are used here. But this solution works for IM in general.
Command
To resolve this problem:
  1. If you have the IM installer files in a macOS folder like Downloads or Documents, move them to a folder that you created manually in a non-special location, like the root of your home directory (for example: ~/installers).
  2. Open the Terminal application.
  3. cd to the RPT_SETUP directory.
  4. Run the command: sudo xattr -rcs .
    This command removes the extended attributes for all the files under the current directory. Some of these attributes are preventing the installation. Since these attributes are not required for the installation, it is safe to remove all of them.
  5. Enter your sudo password.
    This screen capture shows the previous steps:
  6. Verify that all metadata was stripped by using this command:
    sudo xattr -lr .
    This command returns no output if the metadata was successfully stripped. If there is output, that means all metadata was not stripped. Do not proceed to the next step until all metadata is stripped.
  7. Go back to Finder and run Install.app.
  8. IM now starts and you can proceed with the installation.

Mounting volumes on macOS can be done using Disk Utility.app. For some reason, Apple decided not to show EFI partitions (among others such as Preboot, Recovery, etc) in Disk Utility.app. In this article, I will show you how to mount these volumes using command line (Terminal).

Listing all volumes

To list all volumes (partitions), use diskutil list.

As you can see, there are 2 physical drives, both containing EFI partition.

If you compare it to Disk utility.app, it is rather brief.

Mounting a volume

To mount a volume, use sudo diskutil mount DiskIdentifier|DeviceNode|VolumeName.

This will mount the volume to /Volumes/<VolumeName>. If this mount point is already in use, a number will be added at the end (e.g: /Volumes/EFI 1).

Update

The sudo command in the beginning is very import, omitting it causes error message like

Mounting a volume to specified mount point

You can mount a volume to a different mount point (directory) using -mountPoint option. Beware, target mount point must exist.

Sudo Command Not Found Mac Catalina Update

Unmounting a volume is as easy as mounting a volume, use diskutil umount DiskIdentifier|DeviceNode|VolumeName.
