Skype Not Working on Mac? Fixes That Work

If Skype is not working on your Mac, the fix is usually a combination of checking your internet connection, updating the app, and resetting its preferences. This guide walks you through the most common causes and step-by-step solutions to get Skype running again.

Why Skype Fails on macOS

Skype on a Mac can fail for several reasons. The most frequent culprits are an outdated app version, corrupted cache files, or a conflict with macOS permissions. Less common but equally disruptive are network issues, such as a strict firewall or a VPN that blocks Skype’s servers. Understanding the root cause helps you apply the right fix the first time.

Quick Checks Before You Troubleshoot

Before diving into deeper fixes, verify the basics. These take less than a minute and solve a surprising number of problems.

• Check your internet: Open a browser and load any website. If it fails, restart your router or switch from Wi-Fi to Ethernet.
• Check Skype’s status: Visit the official Skype status page (status.skype.com) to see if there is an ongoing outage. If there is, you only need to wait.
• Check the date and time: Go to System Settings > General > Date & Time. Ensure “Set time and date automatically” is on. An incorrect clock breaks Skype’s encryption handshake.
• Restart the app: Quit Skype completely (Cmd+Q), then reopen it. This clears temporary glitches.

Fix 1: Update Skype to the Latest Version

Microsoft releases frequent updates for Skype. An outdated version often stops working after a macOS update. Here is how to update:

1. Open Skype.
2. Click Skype in the menu bar (top-left of your screen).
3. Select Check for Updates.
4. If an update is available, follow the prompts to install it. You may need to restart your Mac.

If you downloaded Skype from the Mac App Store, updates come through the App Store instead. Open the App Store, click your name at the bottom-left, and look for pending updates.

Fix 2: Reset Skype’s Preferences and Cache

Corrupted preference files or a bloated cache can cause Skype to crash, freeze, or fail to sign in. Resetting them forces Skype to rebuild fresh data. Your chat history and contacts are stored on Microsoft’s servers, so you will not lose them.

1. Quit Skype completely (Cmd+Q).
2. Open Finder.
3. In the menu bar, click Go > Go to Folder.
4. Type ~/Library/Application Support/Skype and press Return.
5. Inside this folder, find the subfolder named after your Skype username (e.g., john.doe). Move that folder to your Desktop as a backup.
6. Also go to ~/Library/Preferences and look for files starting with com.skype.skype or com.skype.Skype. Move them to the Desktop too.
7. Relaunch Skype and sign in again. If everything works, you can delete the backup folders.

If Skype still misbehaves, also clear the cache in ~/Library/Caches/com.skype.skype by moving that folder to the Desktop.

Fix 3: Check Microphone and Camera Permissions

Skype may open but your microphone or camera is grayed out. This is almost always a macOS permission issue. macOS blocks apps from using the mic or camera until you explicitly allow them.

1. Open System Settings (Apple menu > System Settings).
2. Scroll to Privacy & Security.
3. Click Microphone in the left sidebar.
4. Ensure the toggle next to Skype is enabled. If it is off, turn it on.
5. Repeat the same for Camera.
6. Quit and reopen Skype.

If you still see no video or audio, test the hardware with another app like FaceTime or QuickTime Player. If the hardware works there, the issue is Skype-specific.

Fix 4: Network and Firewall Settings

Skype needs certain ports and protocols to connect. A strict firewall or VPN can block them. Here is what to try:

• Disable your VPN temporarily. Some VPNs route traffic through servers that Skype cannot reach.
• Check macOS Firewall: Go to System Settings > Network > Firewall. If it is on, click Options and make sure “Block all incoming connections” is unchecked. You can also add Skype to the allowed apps list.
• Reset the network: Turn off Wi-Fi, wait 10 seconds, turn it back on. If you are on a corporate or school network, ask the administrator if Skype is blocked.
• Change DNS: In System Settings > Network > Wi-Fi > Details > DNS, add 8.8.8.8 and 8.8.4.4 (Google DNS). This sometimes resolves connection timeouts.

Fix 5: Reinstall Skype Completely

If none of the above works, a clean reinstall removes any deeply corrupted files. Follow these steps:

1. Quit Skype.
2. Open Finder > Applications.
3. Drag Skype to the Trash.
4. Empty the Trash.
5. Go to the official Skype download page (skype.com) and download the macOS version.
6. Open the downloaded .dmg file and drag Skype to Applications.
7. Launch Skype and sign in.

This removes the app but keeps your login credentials on Microsoft’s servers, so you can sign back in without losing contacts or history.

Frequently Asked Questions

Why does Skype keep crashing on my Mac?

Crashing usually points to corrupted cache or preference files. Follow Fix 2 to reset them. If it still crashes, try reinstalling (Fix 5). Also ensure your Mac has enough free storage space—Skype needs room for temporary files.

Can I use Skype on an older macOS version?

Skype requires macOS 10.13 (High Sierra) or later. If you have an older version, the app may not install or may stop working. Microsoft no longer supports older macOS versions, so your only option is to use Skype in a web browser instead.

Why is Skype not signing in on my Mac?

Sign-in failures are often due to an incorrect date/time, network issues, or a blocked account. Check your clock, disable VPN, and try again. If you get a specific error code, search it on Microsoft’s support site—most have a known fix.

How do I fix Skype audio not working on Mac?

First, check the input/output devices in Skype: go to Skype > Preferences > Audio & Video. Select the correct microphone and speaker. Then check macOS permissions (Fix 3). If audio still fails, test with QuickTime Player to rule out a hardware issue.

Will I lose my chat history if I reinstall Skype?

No. Your chat history and contacts are stored on Microsoft’s servers. After reinstalling and signing in, your history will sync automatically. However, if you had local files (like received files) that were not uploaded, they may be lost.

Is there a way to use Skype without installing it?

Yes. Microsoft offers Skype for Web at web.skype.com. You can sign in with your Microsoft account and use most features, including calls and chats, directly in your browser. This is a good fallback if the desktop app fails.
