Which ESET download do you need for your Mac?
NOD32 itself is a Windows app. On macOS, ESET provides ESET Cyber Security on the same download page. Click the Apple menu > About This Mac to check your macOS version.
ESET Cyber Security 10 runs on macOS Ventura (13) through macOS 27, needs 350 MB of memory and 1600 MB of free disk space.
| Your Mac | What to do | Note |
|---|---|---|
| macOS 13 or later, Intel or Apple silicon | Download ESET Cyber Security | Use the Download for macOS section |
| macOS 12 or earlier | Update macOS first | ESET Cyber Security 10 starts at macOS 13 |
| Running ESET Cyber Security Pro | Move to ESET Cyber Security | ESET lists Cyber Security Pro as end of life |
To install, open the downloaded file and double-click Install ESET Cyber Security. Close other programs and remove other antivirus apps before you start.
Is ESET NOD32 Antivirus free?
No. ESET NOD32 Antivirus is a paid subscription. ESET offers a free 30-day trial, and the trial needs no credit card.
The prices eset.com shows apply to the first term only. ESET emails you about any renewal price change.
Start the free 30-day trial from the official download page, then buy a subscription only if you plan to keep it. The trial needs no payment details, so nothing is charged when it ends. Sites offering a free full version, a license key generator or a cracked build are not from ESET.
Should you install ESET NOD32 Antivirus 19 or keep 18.2?
The current release is 19.2.10.0. Version 19.0.14.0 removed support for 32-bit operating systems, so 18.2 is the final version for 32-bit Windows.
Windows 10 32-bit itself reached end of support on October 14, 2025.
Install version 19 on any 64-bit or ARM64 PC. Keep 18.2 only on a 32-bit Windows 10 machine you cannot replace. Version 19 is the line ESET keeps developing, with 19.2 splitting settings import and export and turning on SHA256 by default. A 32-bit PC receives no new versions.
