How to Extract TAR.LZMA Files on Mac

UnFox extracts TAR.LZMA archives on Mac by decompressing the LZMA layer and extracting the TAR contents in a single operation. LZMA (Lempel Ziv Markov chain Algorithm) provides high compression ratios and is the predecessor to the XZ format. macOS does not include native LZMA decompression for archive files.

What Is a TAR.LZMA File?

TAR.LZMA files use the older standalone LZMA compression format applied to a TAR archive. LZMA was developed by Igor Pavlov for the 7-Zip project and offers compression ratios significantly better than gzip. The .tar.lzma extension predates the newer .tar.xz format, which uses LZMA2 in the XZ container. TAR.LZMA files still appear in older software releases and some Linux distribution archives.

How Do You Extract a TAR.LZMA Archive on Mac?

Drag the .tar.lzma file onto UnFox. The app detects the LZMA stream header, decompresses the data using liblzma, and extracts the TAR contents. Both steps complete in a single operation with progress tracking. UnFox handles TAR.LZMA identically to TAR.XZ from a user perspective, abstracting the format differences entirely.

TAR.LZMA is one of nine TAR variants UnFox supports, alongside TAR.GZ, TAR.XZ, TAR.ZSTD, and more. all supported TAR variants and compression formats for Mac.

UnFox detects legacy LZMA compression automatically and handles the full extraction pipeline in one step. archive extraction features for Mac, iPhone, and iPad.

Frequently Asked Questions

TAR.LZMA uses the older standalone LZMA format, while TAR.XZ uses the newer LZMA2 algorithm in the XZ container. Both achieve similar compression ratios. UnFox supports both.
UnFox provides a graphical interface for TAR.LZMA extraction. Drag the file onto the app and click Extract. No command line tools are required.
