Ext4Kit

Read and write Linux ext4 drives on your Mac. Plug in a USB drive, SSD, or SD card formatted on Linux, a Raspberry Pi, or a gaming handheld, and it appears in Finder like any other disk.

Download free on the Mac App Store

Reading is free. Writing is a one-time in-app purchase, with 14 days included.

Reading is free

Every ext4 drive mounts read-only at no cost, for as long as you like. Browse, search, preview, and copy files to your Mac.

Write Access

A one-time purchase unlocks writing: copy files onto the drive, create folders, rename, delete, and edit in place. Fourteen days of writing are included so you can try it first. Purchases follow your Apple ID.

Built on FSKit, built for safety

Ext4Kit uses Apple's modern file-system framework: no kernel extension, nothing to disable in Recovery. Every change is journaled the same way Linux does it, so an unplugged cable leaves the drive consistent and the next mount, on a Mac or on Linux, replays the journal cleanly.
