Unmarked system requirements
Last updated
Unmarked runs on any Mac with macOS 15 (Sequoia) or later, on both Apple silicon and Intel. It's a universal build, so it runs natively either way, no Rosetta. The app is free.
What you need
- macOS 15 (Sequoia) or later. Earlier versions won't run it.
- A Mac with Apple silicon or Intel. Both run natively.
- Unmarked itself, free from the Mac App Store or as a 7.4 MB direct download from untitledapps.dev/unmarked. Installed, it takes about 15 MB.
That's the whole list. No account, no internet connection, nothing extra to install alongside it.
Check your macOS version
- Click the Apple menu () in the top-left corner.
- Choose About This Mac.
- Read the macOS name and number. If it says Sequoia (15) or higher, you're set.
If you're on an older version, update through Apple menu ▸ System Settings ▸ General ▸ Software Update, then install Unmarked. If your Mac can't update to macOS 15, it can't run Unmarked.
Apple silicon or Intel
Both work, and you never pick a version. You get full speed on an M-series Mac and on an Intel Mac alike, because the build carries native code for each.
