Mac OS X insists that there must be a TAR archive inside XZ files or it will choke on it. Only XZ files containing a TAR archive are supported. Single-file XZ file streams like those created by XZ Utils, 7zip, and other popular compression utilities are entirely unsupported. It turns out the XZ support in Mac OS X 10.10 is kind of broken. Without installing anything, a TAR archive can be created with XZ compression using the tar program with the undocumented -xz argument. XZ Utils can, however, be installed using homebrew for anyone wanting to distribute software or other files in XZ files. Neither is XZ Utils included for use in the command-line. There’s no way to create XZ files from the graphical user interface. XZ only supports a single file so another format, like TAR, must be used to create an archive to contain multiple files in one compressed file. tar.xz for TAR archives compressed in an XZ file. On most files, it will produce files that are much smaller than those of the venerable ZIP format.Īrchive Utility has added support for the file extensions. XZ is a file format that uses the highly efficient LZMA compression algorithm. XZ files can now be opened effortlessly by double-clicking on downloaded XZ files. Its interface is seen as a small window showing the overall progress of the operation. The built-in Archive Utility on Mac OS X 10.10 “Yosemite” now supports decompressing/extracting from the highly efficient XZ compression format.Īrchive Utility is a small program that opens when users compress or decompress files in Mac OS X. I’ve stumbled upon a pleasant new feature for those who like their downloads compact and fast.
