1. Download the PyColormap4Matlab library from the following link: https://www.mathworks.com/matlabcentral/fileexchange/68239-pycolormap4matlab
2. Rename the package to PyColormap4Matlab,
3. Copy & paste the new folder in your Documents as /Documents/MATLAB/PyColormap4Matlab,
4. Open the MATLAB application and link the new folder PyColormap4Matlab to it using the "Home > Set Path" tab in the top menu. Next, click "Add Folder" and select /Documents/MATLAB/PyColormap4Matlab, then click on Open, Save, and Close.
5. Install the “Matplotlib" library. To do so, enter the command "pip3 install matplotlib" in the terminal. For other options, check https://www.geeksforgeeks.org/how-to-install-matplotlib-on-macos/
6. Now, you can import the colormaps from Matplotlib to MATLAB. The following MATLAB script imports the colormap Greys from Matplotlib to MATLAB. The name of the new colormap in MATLAB is cl_Greys:

• # set the Python path
• path_python = '/usr/bin/python3';
• # importing Greys colormap from Matplotlib
• cl_Greys = getPyPlot_cMap('Greys', [], [], path_python);

• Hint: to find the Python path (for variable "path_python") enter the "which python3" command in the terminal.

• For a list of Matplotlib colormaps, check the following link: https://matplotlib.org/stable/tutorials/colors/colormaps.html
• In the following pictures, prepared by Kamyar Mohseni, different classes of Matplotlib colormaps are compared together and also with MATLAB colormaps.

Problem:
How one can clean the ‘dot underbar‘ files or ‘Apple double‘ files?
Solution:
1) Open up the terminal application and enter the following command to merge & delete the files:
$ dot_clean -m DIRECTORY_ADDRESS

DIRECTORY_ADDRESS is the address of the folder or the directory that you want to clean the  ._ files.
If you want to delete all ._ files in your MAC just replace it with ‘./’.
2) or you can delete the files by entering the following command in the terminal:
$ find DIRECTORY_ADDRESS -name ._\* -delete

Problem:
How one can make free the allocated RAM to the file cache?
Solution:
Open up the terminal application and activity monitor. In terminal enter the command:
$ sudo purge

If one checks the activity monitor it should show the reduction in RAM usage on the Mac and the file cache should be cleared.

To solve the problem of running gedit on Mac OS X Mavericks, we need to update the version of libxml2 packaged with gedit as follow:
3) use the command
$ brew install libxml2
4) and then
$ cp /usr/local/Cellar/libxml2/2.9.0/lib/libxml2.2.dylib /Applications/gedit.app/Contents/Resources/lib/
point: If in the last step, you get the error message
“cp: /usr/local/Cellar/libxml2/2.9.0/lib/libxml2.2.dylib: No such file or directory”
you need to check the version of installed libxml2 on your system (here it is supposed to be 2.9.0) and change the version in cp command.

If there are problems with information in your mailboxes, you might see an alert message saying that Mail needs to repair your mailboxes by reindexing your messages for you.
At other times, you may want to reindex messages yourself—for example, when searching mailboxes using Subject, To, or From doesn’t return the correct results.

1) Quit Mail if it is open.
2) In ~/Library/Mail/V2/MailData, delete any file that begins with “Envelope Index,” such as Envelope Index, Envelope Index-shm or Envelope Index-wal.
3) Your home Library folder is hidden by default. To display it, choose Finder > “Go to Folder” and then enter “~/Library”.
4) Then open Mail. Mail creates new Envelope Index files. This process may take a few minutes, depending on how many messages Mail is reindexing.

The Dropbox daemon works fine on all 32-bit and 64-bit Linux servers. To install, run the following command in your Linux terminal.
32-bit:
$ cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86" | tar xzf -
64-bit:
$ cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -
Next, run the Dropbox daemon from the newly created .dropbox-dist folder.
$ ~/.dropbox-dist/dropboxd
Tip:
If you're running Dropbox on your server for the first time, you'll be asked to copy and paste a link in a working browser to create a new account or add your server to an existing account. Once you do, your Dropbox folder will be created in your home directory. Download this CLI script to control Dropbox from the command line. For easy access, put a symlink to the script anywhere in your PATH.

After taking the Java update via the App store, Matlab will launch and open the last file, however, it will freeze and don't open any file. This is a Java issue and reinstalling Matlab or a new user profile will not resolve.
Context - Affects MATLAB 2012b and earlier, with the Java for OS X 2013-004 update - The original update gives build 1.6.0_51-b11-456-10M4508 - This can be verified by running the command below in terminal and comparing the build
$ java -version
Good:
Java(TM) SE Runtime Environment (build 1.6.0_45-b06-451-11M4406)
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-457-11M4509)
Bad:
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-456-10M4508)

SOLUTION - Apple's update has been fixed, however, it is not being pushed via updates to clients already affected. It is now safe to update via the Appstore, Java for OS X 2013-004 is the package. - If you are stuck on version 10M4508, you can manually update:
* for 10.7/10.8: http://support.apple.com/kb/DL1572
* for 10.6: http://support.apple.com/kb/DL1573

METHOD 1:
1) Install Xcode:
$ xcode-select --install
2) Install open motif
$ sudo port install openmotif
3) Install Xmgrace
$ sudo port install grace
4) Open Xmgrace and enjoy!
$ xmgrace

METHOD 2:
1) Install motif libraries. You can download binary from here:
http://www.ist.co.uk/downloads/motif_download.html
2) Grace download and install:
$ cd Desktop
$ wget ftp://ftp.fu-berlin.de/unix/graphics/grace/src/grace5/grace-5.1.23.tar.gz
$ tar xzvf grace-5.1.23.tar.gz
$ cd grace-5.1.23
$ ./configure --x-includes=/usr/X11/include --x-libraries=/usr/X11/lib --with-motif-library=-lXm --with-extra-incpath=/usr/OpenMotif/include:/usr/local/fftw-3.3.4/include --with-extra-ldpath=/usr/OpenMotif/lib:/usr/local/fftw-3.3.4/lib
$ make
$ sudo make install
$ echo "export PATH=$PATH:/usr/local/grace/bin" >> ~/.bashrc
$ source ~/.bashrc
$ xmgrace
Tips:
- on Mac OS X Lion, wget doesn't work. Use curl -O instead of wget.
- if in the last step, when you try to run xmgrace, you get the following error:
$ xmgrace
Can't open display
Failed initializing GUI, exiting
you can try:
$ DISPLAY=:0.0 xmgrace
if it doesn’t solve the problem, you need to open XQuartz and then enter the following command:
$ DISPLAY=:0.0 xmgrace
