MacOS Catalina was released on October 7, 2019, and has been causing quite a stir for Anaconda users. Apple has decided that Anaconda's default install location in the root folder is not allowed. It moves that folder into a folder on your desktop called 'Relocated Items,' in the Security folder. If you've used the .pkg installer for Anaconda, this probably broke your Anaconda installation. Many users discuss the breakage at https://github.com/ContinuumIO/anaconda-issues/issues/10998.

I'm also adding some other books as supplements notably Unix in a Nutshell and A Practical Guide to UNIX for Mac OS X Users. Terminal is Mac OS X way into the command line world. It is designed for you to typing in specific commands that you would not be able to do otherwise. This is great for customizing your Mac and unveiling hidden features. It is also a good way to destroy you system because you screwed something up. ITerm2 is a replacement for Terminal and the successor to iTerm. It works on Macs with macOS 10.12 or newer. ITerm2 brings the terminal into the modern age with features you never knew you always wanted. Why Do I Want It? Check out the impressive features and screenshots. If you spend a lot of time in a terminal, then you'll appreciate all the.

There is unfortunately no simple fix for your current installation. Some people have recommended moving the Anaconda folder from the 'Relocated Items' folder back to your home folder, followed by modifying PATH to point at the new location. This is a partial fix, and may restore some core functionality for you. Unfortunately, many files in a given conda environment contain hard-coded paths to their install path (AKA prefix). When you copy or move folders around, these hard-coded paths are not accurate, and programs in your environment might look for other things in the wrong place and break.

So, where to go from here? You have several options.

Reinstallation

Choose one:

    Start fresh with a new Anaconda installation. Pay attention during installation to make sure that your install path is a subfolder of your home folder, such as /Users/me/anaconda3Start fresh using the .sh installer instead of the .pkg installer. This installer makes it simpler to choose the destination path, and gives you more choice on how you want your shell to behave.

We have tested the currently available shell installers, and found them to work fine with Catalina. If you rely on the GUI installer instead, you'll need to wait for the soon-to-be-released Anaconda 2019.10 installer, which will be signed and notarized in accordance with Apple's more stringent policies.

Repair

This is experimental, but will allow you to fix your old installation and keep all of your old environments. To do this, you'll use our self-contained prefix replacement tool at https://repo.anaconda.com/pkgs/misc/cpr-exec/cpr-0.1.1-osx-64.exe Note that although these files have a '.exe' file suffix, they are not Windows executables. We use the .exe suffix to indicate a standalone executable.

The experimental tool uses pyinstaller to make a standalone execution from code at https://github.com/conda/conda-prefix-replacement, which is a consolidated collection of the prefix detection and replacement code that is spread between conda and conda-build. We've added a novel feature to CPR for 'rehoming' environments, which is the functionality needed to address the moved environment problem. Specifically, given the current (new) prefix, rehoming attempts to detect the old prefix from files within, and then adjust the detected files to have the new prefix value.

In steps:

1. At a terminal, download the file and make it executable:

2. Run the CPR tool to fix embedded paths:

Let's say you started with an install to /Anaconda3, which Apple helpfully moved to 'Relocated Items.' You have moved that folder to ~/anaconda3. Example commands for using CPR to fix this are:

Again, that finds your old prefix by looking in some files that are known to record the prefix in a readily parseable way. If that fails, you can still fix things as long as you know what the original path was:

The CPR command is recursive. Because environments default to the envs folder within your Anaconda[2|3] folder, CPR will fix all of your environments within your base prefix as well.

3. Re-run conda init to fix your conda shell command:

NOTE: if you use a shell other than bash, specify it in the conda init command:

4. Fix your ~/.conda/environments.txt file:

Open the ~/.conda/environments.txt file, and find/replace all instances of the old install location (e.g. /Anaconda3) with the new one (e.g. ~/anaconda3).

5. Find any remaining references to the old environment in other configuration files:

Many packages in Anaconda manage their own configuration files, typically in some subfolder of your home directory. You can use a tool like grep or ripgrep to find these files. You'll then need to edit them and fix the paths as you did with the environments.txt file. An example grep command might be:

We hope this helps you get back on track.

Apple's macOS platform includes Terminal, which is equivalent to Command Prompt in Windows OS. Since the macOS is based on UNIX, Terminal might give you a vibe of a dangerous tool where one wrong command can wreck your system. Sure, it is valid only to an extent. There are a bunch of harmless commands that are usable in customizing the interface and other settings of macOS.

The Terminal on macOS can be extremely useful in tweaking the performance of your Mac. Now it entirely depends on what you want to achieve. In case you have been dreading to use it, you can always get comfortable by using simpler tricks. Here are the top 11 terminal command tricks to try on your Mac.

Also on Guiding Tech How To Speed Up a Slow Mac Read MoreNote: While selecting/copying a command, make sure you scroll all the way towards right to select the complete command in the gray box. Otherwise partial commands will not work as intended.

1. Open Folders

One of the coolest ways to get familiar with the Terminal is to use it to open files and folders. I know that clicking on Finder will do the same. However, using Terminal, you can open a specific folder or a file without exposing your file structure to anyone.

Let's say you want to open your Documents folder. Then you can type the following command and then hit Enter.


And that opens my Documents folder. There's a DOCX file in there. I can use Terminal to open that too. For that, you need to type out the command with some requirements — the path of the respective file:

Open -a 'Application Name' /Path/to/File

So for opening the DOCX file in the Documents folder of my Mac, I typed in the command below and then hit Enter:


That opens up the specific file using the predefined program. You can also use the wildcard character (*.extension) instead of the full filename. However, if you have more than one file in carrying the same extension, then it might freeze your Mac for a bit.

2. Change Default Save Screenshot Location

By default, the macOS Mojave stores the screenshots on the Mac's desktop. Now if you have iCloud sync enabled, which I am sure you do, then it keeps uploading to your account. Thankfully, you can change the save location for the screenshots instead of crowding your desktop.

Here's the command you need to type before hitting Enter:


In the above command, you can provide any specific file location instead of ~/Downloads as shown.


After hitting Enter, I need to reset the SystemUIServer for the changes to take effect immediately. So feed in the following command.


Though it is not required, I would recommend restarting your Mac.

3. Change Screenshot Image Type

The macOS saves the screenshots in JPG format by default. You can change that to save them in PNG or PDF formats too. Here's how to do that quickly with this specific command:


After that, you need to kill the SystemUIServer again.
Most commands which require some system changes shall mandate shutting down the SystemUIServer. So do that quickly.


Now, your new screenshots will save in the PNG format. Do note that PNG files are generally larger than JPG files. So keep an eye on how much storage space they consume.

4. Show Hidden Files

Have you tried looking for the option to let the Finder show hidden files? Well, it is tougher than picking the show hidden files on Windows. I always forget how to enable that. Thankfully there is a helpful command that makes it happen in a few seconds.


After that, you need to force shut the Finder.


Now you should see a lot of hidden files in the Finder. They would be greyed out but still visible. If you roll back this change, then you need to change TRUE to FALSE in the command.

5. Switch Off the Dashboard

Apple promoted the Dashboard view to access calculator and sticky notes quickly. I bet you rarely use that one for you can launch the Calculator app or Sticky Notes app using Mission Control of Spotlight. So you can switch it off and don't have to worry about opening it by mistake.

Here's the command to turn off the Dashboard.


Next, you must kill the Dock so that the changes are correctly applied.


Now I don't have to worry about accidentally opening the Dashboard. If you want to switch it on again, then change TRUE to FALSE in the command.

6. Download Files

Did you know that you can download files using the Terminal? Yes, you don't need to keep the browser running just for that file. The only requirement here is that you must have the file's download link. So the command syntax is:

curl -0 downloadlink

First, navigate to the folder where you want to download the file. For that, you need to switch to the Downloads directory.


After that, you can feed the command to download the VLC for macOS from the official site. It would appear something like this:

Note: There is a letter O in the command and not the 0 (zero).

7. Ditto for Backups

Copying files and taking backups on macOS is quite swift — thanks to the SSDs and the flash storage. However, it does take a while to copy a large amount of data. Thankfully, Terminal offers a useful command to copy files. Here's how you can do it while watching the name of files that the command copies.

ditto -V /currentpath/ /new/path/

So I want to copy the DMG downloaded in the previous section to the desktop.

That should do the needful. If you want to copy the files to an external drive, then you need to provide the destination path correctly.

8. Always Show File Path in the Finder

If you have switched from Windows recently, you would have noticed that the Finder on macOS doesn't show file path like the Explorer in Windows. However, you can force Finder to show you the file path with this command:

After hitting enter, you need to stop the Finder.

After you hit Enter, the Finder will relaunch. Then you should see the file paths at the top of the Finder window.

9. Power Chime on Connecting the Charger

Has it ever happened that you've connected the MagSafe charger to your Mac but forgot to flip on the power switch? I have lost the count. Thankfully, I stumbled upon this useful command that provides an audio feedback chime whenever I connect the MagSafe charger.

Feed this command in the Terminal and hit Enter.

10. Stop Your Mac from Sleeping

Often you are downloading a massive file, and you don't want your Mac go to sleep. If it is a temporary requirement, then a simple command can make it happen. Just type the following command, hit Enter and walk away from your Mac.

In this command, the number 600 signifies seconds. So with this command, the Mac won't sleep until 10 minutes (600 seconds). You can enter a relevant number of seconds or just the word 'caffeinate' to prevent your Mac from sleeping.

However, if you close that Terminal window, then the command will stop executing and the Mac will go to sleep on a predefined time.

11. Check Your Mac's Uptime

Wondering how long it has been since you've restarted your Mac? A simple restart can sort a lot of things in order and boost your Mac's performance. Here's a command to check your how long your Mac has been running without a Restart or a Shutdown

That should give you all the details with a timestamp.
