Will it run on your Mac?

Chip: Apple Silicon (M1 or later)
No Intel Mac build. Check your chip under Apple menu › About This Mac.
Operating system: macOS 14.2 or later
Memory: 8 GB minimum, 16 GB recommended
Under 8 GB, the app explains why and will not download a model.
Installer: A .dmg file of about 9 MB
Disk space for models: 1.3 GB (Lite pack) or 2.5 GB (Standard pack)
Plus 1 GB free while downloading.
Internet: Needed to download the model and register the Free trial
After that, translation runs offline.

We have not measured performance on a base-model M1 Mac, so we cannot promise latency there. On an 8 GB Mac, the Lite pack is the sensible choice.

Verify the installer (SHA-256)

Only download the installer from an official source.

The genuine .dmg is the one we send from support@aitranslator.io.vn or link to on aitranslator.io.vn. A file from anywhere else could be fake or tampered with. Do not open it, even if it is named AI Translator.

Every installer comes with a SHA-256 checksum that we send you. Compare it before installing:

Open Terminal (Applications › Utilities).
Type shasum -a 256 followed by a space, drag the .dmg file from Finder into the Terminal window to fill in its path (spaces in the file name included), then press Enter. Or type the command below; if the file name contains spaces, keep it in double quotes as in the example.

shasum -a 256 ~/Downloads/"<file-name>.dmg"

Compare the 64-character string it prints with the one we sent. They must be identical.
If they differ, do not open the file. Download it again; if it still differs, contact support.

Drag AI Translator to Applications

Double-click the .dmg file to open it.
Drag AI Translator into the Applications folder in the window that appears.

First launch: why macOS blocks it and how to allow it

macOS uses Gatekeeper to check apps downloaded from the internet. The current AI Translator build is ad-hoc signed and not yet notarized by Apple, because we do not have an Apple Developer ID yet. So macOS blocks the first launch and says it cannot verify the developer. If the file came from us and the SHA-256 matches, this is the normal path for this build.

Open AI Translator from Applications. When macOS says it cannot verify the developer, click Done (the button that closes the dialog; its label may differ slightly between macOS versions).
Open System Settings › Privacy & Security.
Scroll to the bottom of the page and click Open Anyway next to AI Translator.
Confirm with your login password or Touch ID.
The app opens and shows the first-time setup. Continue with the quick start guide.

From macOS 15, the right-click › Open trick no longer works.

Go through Privacy & Security as above. The Open Anyway button usually appears only after macOS has blocked an attempt to open the app; if you do not see it, open the app once more and come back.

This step applies to a downloaded .dmg: you need it the first time you open any build. If you install a newly downloaded .dmg, macOS may block it again. Once we have a Developer ID and notarize the app, this step will go away.

Every update, macOS asks a few things again

This is a consequence of ad-hoc signing. After each update to a new build you will usually see, once:

About 5 Keychain dialogs asking for your Mac login password (we measured 5 on one Mac running macOS 26): enter it and choose Always Allow. Do not choose Deny: the app will not be able to read your license and quota. If you chose it by mistake, quit the app completely, reopen it and choose Always Allow.
1 system audio recording permission dialog (also what we measured): allow it.

After that, later launches do not ask again. You do not lose data, your plan or your quota. On a fresh install we measured no Keychain dialogs (only Open Anyway and the recording permission); if macOS asks anyway, choose Always Allow. The app warns you in the update prompt: “After updating, macOS will ask for your login password a few times and for audio-recording permission once…”. This goes away once we have a Developer ID. A .dmg we send by hand during the beta may not update itself; in that case you download the new .dmg.

Uninstall properly

macOS gives the app no chance to clean up when you delete it, so remove the models and data first, then trash the app:

Open AI Translator and go to Settings › Privacy.
Click Delete models and data, then confirm with Delete everything. The app removes every downloaded model (1.3 or 2.5 GB), your history and your glossary.
Choose Quit from the AI Translator icon in the menu bar.
Drag AI Translator from Applications to the Trash.

Your license and remaining quota are kept, so reinstalling should not lose a plan you bought. The Free trial is tied to your Mac, so reinstalling does not reopen the 10 days. If you already deleted the app without deleting the models, they live in ~/Library/Application Support/com.aitranslator.desktop/models.

Common installation problems

No Open Anyway button. Open the app once more so macOS records the block, then return to Privacy & Security.
It will not install on an Intel Mac. AI Translator is built for Apple Silicon only.
The app says “This computer has less than 8 GB of RAM, which AI Translator does not support yet.” Macs under 8 GB cannot download a model.
The app says “This copy of AI Translator is not genuine, so only Free works.” The installation was altered or came from the wrong source. Download it again from an official source.
macOS asks about the Keychain many times after an update. Normal for an ad-hoc signed build: enter your password and choose Always Allow.

If subtitles do not appear after installing, see how to grant system audio recording permission.
