The following files (.tar.gz) contain the mac 32 bit or 64bit executable
and GNU GENERAL PUBLIC LICENSE

(64 bit  executable)
ddlabz10_MacPB32.tar.gz (32 bit for Mac PowerBook Mac OS X 10.4.11, a bit antique)

(64 bit  executables)
ddlabz10_MacOSX_Monterey.tar.gz (MacOS Monterey Version 12.6.3, thanks to Jose Manuel Gomez Soto)
ddlabz10macMini_Monterey.tar.gz (macMini, macOS Monterey 12.6.4, thanks to Genaro J Martinez)
... these two above may be compatible??

ddlabz10macPro_Mojave.tar.gz (MacBook Pro, macOS Mojave 10.14.6, an oldie thanks to Genaro)

Genaro adds...
to compile correctly,  update the "Xcode" application and install
the "XQuartz" application (this software handles X11 files).

Run DDLab from a terminal in X11, which must be installed.
From the directory with the DDLab files, enter the name of the
executable (renamed ddlabz10) preceded by ./ and followed by &, for example ...
 
./ddlabz10 &

Alternatively, first change directory to "ddfiles"
then enter the name of the executable preceded by ../ and followed by &

../ddlabz10 &

This will keep files generated by DDLab in the ddfiles subdirectory.

----------------------------------------------------------------------
Note on missing hash "#" from some mac keyboards:
"#" is used for some on-the-fly options, for example, to toggle scrolling
space-time patterns. If "#" is missing as in "MacBook Retina 2016",
it can be made with alt(option)3, the alt or option key and key 3.
----------------------------------------------------------------------
You can recompile DDLab yourself from the source code using
various mac Makefiles provided, available at
http://www.ddlab.org/download/ddlab_code_2023/
or previous releases and mirror sites.
DDLab would appreciate news of alternative compiles.
