Your Mac App Store might open to a blank white window, spin on “Loading” forever, refuse your password, or leave an update stuck at 0%. If you’ve been staring at that spinner for 10 minutes, don’t panic. The cause is usually small. First, check whether Apple’s servers are down. Then quit the App Store and restart your Mac. If that doesn’t help, match your symptom below:
- Blank or stuck loading: this usually points to an Apple service outage, your network, VPN, or DNS — always check the status page and try a restart first (Fixes 1–2).
- Sign-in errors: this usually points to your Apple Account session or the date and time setting (Fixes 3–4).
- Stuck downloads: this usually points to low storage or a jammed queue (Fixes 5–6).
- Still broken after all that: move on to the system-level tests (Fixes 7–9).
Before you begin:
- You need a Mac running a currently supported version of macOS. These steps follow the System Settings layout used in macOS Ventura 13 and later, including Sonoma, Sequoia, and Tahoe. Older Macs use System Preferences instead.
- You need an Apple Account and a working internet connection.
- This guide covers the Mac App Store only. The iPhone and iPad App Store steps are different.
Quick Diagnosis: Is It Apple or Your Mac?
Step 0: Check Apple’s System Status Page (30 seconds)
Open Apple’s System Status page in Safari. Look for rows related to the App Store, Mac App Store, and macOS Software Update — note that Apple’s exact service labels and row count can vary by region and change over time, so look for the closest match rather than an exact name.
- Green dot: The service is working normally. The problem is on your end, so keep reading.
- Yellow or red icon: Apple is having an outage. Nothing you change on your Mac will fix it. Wait and check again later.

The 9 Fixes, Quickest First
Fix 1: Quit the App Store and Restart Your Mac
Symptoms:
- The window is blank, white, or frozen.
- Buttons do nothing when you click them.
Why it happens: The App Store’s connection to Apple can get stuck. Quitting the app clears that session. Restarting the Mac also clears the background processes that handle downloads.
Fix:
- With the App Store open, press
Cmd + Qto quit it. If it won’t quit, open the Apple menu > Force Quit, select App Store, and click Force Quit. - Reopen the App Store from your Applications folder, or press
Cmd + Spaceand type “App Store”. - If it’s still blank, go to the Apple menu > Restart.
Verify: The Discover page loads artwork and app listings within a few seconds.
Fix 2: Check Your Network, VPN, and DNS or Content Filters
Symptoms:
- The App Store shows “Cannot connect to App Store.”
- The App Store loads slowly or only partly.
- Downloads never start.
Why it happens: The App Store needs to reach several Apple servers. A VPN, a custom DNS server, an ad blocker, or a firewall can block some of those servers. Other websites may still load fine while the App Store fails.
Fix:
- Open Safari and visit any website to confirm you’re online. If you’re not, check our Wi-Fi troubleshooting guide first.
- Turn off your VPN completely, including any “always on” mode, and test the App Store again.
- Pause any content filter, network-level ad blocker (such as Pi-hole), or third-party firewall app.
- If you set a custom DNS server (the service that turns website names into addresses), go to System Settings > Network > your connection > Details > DNS. Remove the custom entries so your Mac uses your router’s default.
- Check Screen Time limits. Go to System Settings > Screen Time > Content & Privacy and review Store Restrictions.
- Try a different network, such as your iPhone’s Personal Hotspot.
Tip: If the App Store works on a hotspot but not at home, the problem is your router or network. A wired connection through a USB-C to Ethernet adapter can help you rule out flaky Wi-Fi.
Verify: The store loads and a small free app downloads without errors.
Fix 3: Sign Out and Back In, Then Check Payment and Region
Symptoms:
- You see repeated “Could not sign in” messages.
- The App Store shows “Verification Required.”
- Purchases fail even though the store loads.
Why it happens: Your sign-in session can expire or get corrupted. Account problems can also block every download, even free ones. Common ones include an unpaid earlier purchase, an expired card, or an account region that doesn’t match your payment method (Apple Support: sign-in troubleshooting, retrieved Oct 8, 2026).
Fix:
- In the App Store, click Store in the menu bar > Sign Out.
- Restart your Mac.
- Open the App Store, then click Store > Sign In and enter your Apple Account details.
- Click your name in the lower-left corner, then click Account Settings. Look for a payment alert, an unpaid order, or the wrong Country/Region.
- If you see a payment alert or an unpaid order, click it, then click Edit next to your payment method to update an expired card or billing address. If the order still won’t clear, go to reportaproblem.apple.com to view and resolve it directly. If the region is wrong, use the Change Country or Region link in the Apple Account Summary section — note this requires a zero Apple Account balance and no pending subscription cancellations first.
Verify: Your name appears in the lower-left corner, and a free app downloads without a verification prompt.
Fix 4: Set the Date and Time Automatically
Symptoms:
- Sign-in fails with no clear reason.
- You see “Cannot connect” or security certificate errors.
Why it happens: The App Store uses encrypted connections that rely on security certificates. Those certificates are only valid for certain dates. If your Mac’s clock is off by even a few hours, the certificate check can fail. So yes, the date really does matter.
Fix:
- Go to System Settings > General > Date & Time.
- Turn on Set time and date automatically.
- Make sure Set time zone automatically using your current location is on, or pick the correct time zone yourself.
Verify: The clock in your menu bar matches your iPhone. Then try signing in again.
Fix 5: Free Up Storage Space
Symptoms:
- Downloads stall or fail.
- You see a “not enough space” message.
- Updates start and then quietly disappear.
Why it happens: Your Mac needs room for the downloaded file and room to unpack and install it. Apple doesn’t publish an official minimum for this, so treat any number here as a cautious personal guideline, not an Apple-stated requirement: aim for noticeably more free space than the app’s listed size — roughly double it where possible — plus a general cushion of a few GB for macOS itself. If space is tight, prioritize freeing space over hitting an exact figure.
Fix:
- Go to System Settings > General > Storage.
- Check the free space shown at the top.
- Use the recommendations, such as Store in iCloud or Empty Trash Automatically. You can also click the ⓘ next to a category to delete large files.
Tip: If you’re always short on space, move large media libraries to an external SSD. That’s often easier and cheaper than deleting things you want to keep.
Verify: You have plenty of free space, and the download now finishes.
Fix 6: Pause, Resume, or Cancel Stuck Downloads
Symptoms:
- An app sits at 0% or partway through for a long time.
- A dimmed app icon appears in your Applications folder.
Why it happens: A network hiccup during a download can leave the item stuck in the download queue.
Fix:
- In the App Store, click Updates in the sidebar. For a new app, find it on its listing page instead.
- Click the progress circle to pause or stop the download. Wait a few seconds, then click again to resume.
- If it still won’t move, quit the App Store. In Finder, open Applications and drag any dimmed, half-downloaded copy of the app to the Trash.
- Reopen the App Store. Click your name in the lower-left corner to see your purchases, then click the download button (cloud icon) to download the app again.
Verify: The progress circle moves steadily, and the app opens when it finishes.
Fix 7: Install Pending macOS Updates
Symptoms:
- The App Store works some of the time.
- Specific apps refuse to update.
- An app says it “requires a newer version of macOS.”
Why it happens: The App Store is built into macOS, so its bugs get fixed through macOS updates. Many newer apps also require a recent version of macOS.
Fix:
- Go to System Settings > General > Software Update.
- Click Update Now if an update is waiting. If you only see Upgrade Now for a major new version, you can choose to wait on that.
- Let your Mac restart and finish installing.
Verify: The Software Update panel says your Mac is up to date. Then retry the App Store.
Fix 8: Test in Safe Mode
Symptoms:
- The App Store fails even after Fixes 1–7.
Why it happens: Third-party software can interfere with the App Store. This includes system extensions, security tools, and apps that open when you log in. Safe Mode starts your Mac with only Apple’s essential software and clears some system caches. The steps differ between Apple silicon and Intel Macs.
Fix on Apple silicon (M-series) Macs:
- Shut down your Mac.
- Press and hold the power button until you see “Loading startup options.”
- Select your startup disk.
- Hold
Shiftand click Continue in Safe Mode.
Fix on Intel Macs:
- Restart your Mac.
- Immediately press and hold
Shiftuntil the login window appears. - Log in. You may be asked to log in twice.
Either way, “Safe Boot” appears in the menu bar. Open the App Store and test it. Restart normally to leave Safe Mode.
Verify: If the App Store works in Safe Mode, a login item or third-party extension is the likely cause. Go to System Settings > General > Login Items & Extensions. Turn off recent additions one at a time, and test after each change. If the App Store still fails in Safe Mode, move on to Fix 9.
Fix 9: Test With a New User Account
Symptoms:
- The App Store fails for you but works for another person on the same Mac.
- The App Store fails in Safe Mode too.
Why it happens: Damaged files in your user folder can break the App Store for your account only. The rest of the system still works fine. These files can include caches, keychain entries (the stored passwords and certificates on your Mac), or preference files.
Fix:
- Go to System Settings > Users & Groups.
- Click Add User. In some versions this button is called Add Account. Enter your admin password when prompted.
- Create a standard user called something like “Test.”
- Log out of your account, log in as Test, and open the App Store. Sign in with your Apple Account.
Verify:
- The App Store works in the Test account: The problem is in your original user account. Apple Support can help you repair it without wiping your Mac.
- The App Store fails in both accounts: The problem is system-wide. It’s time to contact Apple.
When you’re done testing, delete the Test user from the same Users & Groups panel.

Settings to Check
These are the settings most often behind App Store problems:
- Date & Time: Go to System Settings > General > Date & Time. Make sure automatic time is turned on.
- Software Update: Go to System Settings > General > Software Update. Turning on automatic updates keeps App Store fixes coming.
- Network DNS: Go to System Settings > Network > your connection > Details > DNS. Leave it on your router’s default unless you have a reason to change it.
- Screen Time: Go to System Settings > Screen Time > Content & Privacy. Make sure store restrictions aren’t blocking downloads.
- Store account: In the App Store, click your name > Account Settings. Check that your payment method and region are correct.
When to Contact Apple Support
Stop troubleshooting and reach out when:
- You see an “account disabled” or security-related message.
- Fix 9 shows the App Store is broken for every user on your Mac.
- A charge or unpaid order won’t clear.
- Apple’s System Status page has shown green for a day, but nothing above has worked.
How to reach Apple Support: Use the Apple Support website, the Apple Support app on your iPhone, or book a Genius Bar appointment. Apple’s own Mac App Store download guide is also worth checking.
Before you contact Apple, note your macOS version (Apple menu > About This Mac), the exact error wording, and which fixes you’ve already tried. If an advisor asks for logs, open the Console app from Applications > Utilities. Search for “appstore” while you reproduce the error.
Prevention Tips
- Keep macOS updated: Many App Store bugs are fixed in point updates — for example, Apple shipped macOS 27.0.1 shortly after the initial macOS 27 release to address early issues.
- Leave the date and time on automatic: This one setting prevents a surprising number of sign-in errors.
- Keep extra storage free: Extra headroom beyond what you currently need gives downloads and macOS updates room to install.
- Use VPN split-tunneling: If your VPN supports it, exclude the App Store so it doesn’t route through the VPN.
- Keep your payment method current: An expired card can block even free downloads.
Frequently Asked Questions
Is the App Store down for everyone or just me?
Check Apple’s System Status page. If the App Store rows are green, the problem is on your Mac or your network.
Does a VPN really block App Store downloads?
It can. Some VPN servers and content filters block or slow down Apple’s download servers. Turn the VPN off as a quick test.
Why does the date and time affect sign-in?
The App Store uses encrypted connections that check security certificates against your Mac’s clock. If the clock is wrong, those checks fail.
How do I tell if the problem is my account or my whole Mac?
Use the new-user test in Fix 9. If the App Store works in the new account, the problem is your user account. If it fails in both, the problem is the whole Mac.
Wrapping Up
Most App Store problems on a Mac go away with the first four fixes: checking Apple’s status page, restarting, checking your network, and signing out and back in. Safe Mode and the new-user test take longer. But they tell you exactly where the problem lives before you call Apple. If you skip everything else, at least check the date and time and your VPN, because those two cause a lot of trouble.
