How to update WhatsApp on Mac
WhatsApp recommends keeping the app updated on linked devices, because updates carry fixes for bugs. The route depends on where you got the app.
- Open the App Store on your iMac if you installed WhatsApp from there.
- Click Updates in the sidebar.
- Click Update next to WhatsApp.
- If you installed WhatsApp from its website, go to the WhatsApp Download page in your browser and download the Mac version again.
- Open the downloaded file and follow the prompts.
- Reopen WhatsApp and click the chat contact.
Your phone app needs updates too, so update WhatsApp manually there as well.
Does WhatsApp work on Mac? Supported macOS versions
Apple's advice for a misbehaving app includes checking that it is compatible with your version of macOS. WhatsApp's help pages differ here: the download page says macOS 11 or later, while two others say macOS 12.1. Treat macOS 12.1 as the minimum.
| How you use WhatsApp | What it needs | If you fall short |
|---|---|---|
| WhatsApp for Mac app | macOS 12.1 or newer | Update macOS, then download the app |
| WhatsApp Web in Safari | Safari 15 or later | Update macOS, because Safari updates with it |
| WhatsApp Web in Chrome or Edge | Version 100 or later | Update the browser |
| WhatsApp Web in Firefox | Version 115 or later | Update the browser |
| WhatsApp Web in Opera | Version 86 or later | Update the browser |
To update macOS, go to System Settings > General > Software Update. On an older iMac that cannot update, WhatsApp Desktop will not install on macOS Catalina, so use WhatsApp Web.
How to log out of WhatsApp on Mac and link it again
Linking again makes your phone send a fresh encrypted copy of your recent message history to the iMac, so it is the fix to try after an update. Your chats stay on your primary phone.
- In WhatsApp on your iMac, go to Settings > Log out > Log out.
- Open WhatsApp on your primary phone and go to Linked devices.
- Check that the iMac is gone from the list. If it is still there, tap it and tap Log out.
- Tap Link a device and verify your identity if prompted.
- Point the phone at your iMac screen and scan the QR code.
- Leave both devices online for a few minutes while your message history appears.
Your primary phone can link up to four devices. Open WhatsApp on that phone at least every 14 days to keep them connected. WhatsApp also disconnects a linked device after 30 days of inactivity.
If linking stops with an error message, you can fix the WhatsApp Desktop unexpected error on Mac before trying again.
How to reinstall WhatsApp on iMac
- Quit WhatsApp, or force quit it if it will not close.
- Click the Finder icon in the Dock, then click Applications in the sidebar.
- Drag WhatsApp to the Trash at the end of the Dock.
- Download WhatsApp for Mac again from the App Store or the WhatsApp Download page.
- Open the app and follow the prompts to finish the installation.
- Link the app to your phone again by scanning the QR code.
If your Mac says the app is in use, make sure WhatsApp is closed, or restart your iMac and try again. Use only the App Store or whatsapp.com, because linking through an unofficial app can get your account banned.
How to use WhatsApp Web for Mac while the app is blank
WhatsApp Web runs in your browser and needs no download, so it keeps you messaging while you repair the app.
- Go to web.whatsapp.com in Safari or another supported browser on your iMac.
- Open WhatsApp on your primary phone and go to Linked devices > Link a device.
- Scan the QR code shown in the browser.
- Click the same chat contact to see whether the problem follows you.
If the contact opens normally in the browser, the problem sits with the Mac app rather than your account or that chat.
Is WhatsApp linked to my Mac? How to see linked devices
- Open WhatsApp on your primary phone.
- Go to Linked devices to see every computer tied to your account.
- Look for your iMac in the list.
- Tap any device you do not recognise, then tap Log out.
A working fix looks like this: your iMac is listed, the chat contact opens, and a test message you send there also appears on your phone.
WhatsApp messages on Mac not showing in a chat
The chat opens but its older messages are missing
Not all messages and chats sync from your phone, and WhatsApp reports a known issue with some linked devices not showing up to one year of history.
- Open the chat on your primary phone, which keeps your full history.
- Update WhatsApp on the iMac.
- Give the linked device a few minutes to load the history.
WhatsApp stopped working after your phone sat unused
Linked devices log out if the primary phone is unused for over 14 days.
- Open WhatsApp on your primary phone.
- Go to Linked devices > Link a device.
- Scan the QR code on your iMac.
A yellow icon appears next to Computer not connected
Your iMac may not have an active internet connection.
- Check your connection, and contact your internet provider if you are offline.
- Turn your iMac off, wait 30 seconds, and turn it back on.
- Try a different Wi-Fi network or a hotspot, because office and campus networks can block WhatsApp.
- On a managed network, ask the administrator to bypass traffic to
web.whatsapp.comand.whatsapp.net.
WhatsApp stays frozen after a force quit and restart
A recently connected device or an add-on can stop a Mac app from working.
- Disconnect any peripheral you just connected, such as a printer.
- Uninstall plug-ins or enhancements from other manufacturers.
- Choose System Settings > General > Software Update to install macOS updates.
WhatsApp Web for Mac blank page in Safari
The WhatsApp Web page is blank or will not load in Safari
Saved browser data or an old browser can stop the page from working.
- Refresh the WhatsApp Web page.
- In Safari, choose Safari > Settings, then click Privacy.
- Click Manage Website Data, select the WhatsApp entries, then click Remove. This can sign you out of the site.
- Log back in to WhatsApp Web with the QR code.
- Make sure you have Safari 15 or later, or try the page in Chrome, Edge, Firefox or Opera.
If the page still fails, try the other ways to fix WhatsApp Web when it doesn't load.
