App Store Blank in macOS Sierra? Fix It

If your Mac running macOS Sierra shows a blank or white App Store window, the fix usually involves resetting the App Store’s cache, checking your network settings, or updating to a newer macOS version. This article walks you through the most effective solutions, from quick terminal commands to full system updates, so you can get the App Store working again.

Why the App Store Goes Blank in macOS Sierra

The App Store in macOS Sierra (10.12) relies on a web-based interface that can fail to load for several reasons. Common culprits include corrupted cache files, an outdated system certificate, network proxy issues, or simply that Apple has stopped fully supporting this older macOS version. Since Sierra is no longer the latest operating system, some App Store features may not work as expected, but a blank window is usually fixable.

Quick Fixes to Try First

Before diving into more complex steps, try these simple actions—they resolve many blank App Store issues:

• Force quit and reopen: Press Command + Option + Esc, select “App Store,â€� and click “Force Quit.â€� Then reopen it from the Applications folder.
• Restart your Mac: A fresh start clears temporary glitches.
• Check your internet connection: Open a web page in Safari to confirm you have network access.
• Sign out and back into the App Store: In the App Store menu, go to Store > Sign Out, then sign in again.

If these don’t work, proceed to the more targeted fixes below.

Reset the App Store Cache

Corrupted cache files are a leading cause of a blank App Store. Resetting them forces the app to rebuild its data. Here’s how:

1. Quit the App Store completely.
2. Open Finder and press Command + Shift + G to open the “Go to Folderâ€� window.
3. Type ~/Library/Caches/com.apple.appstore/ and press Enter.
4. Select all files in that folder (press Command + A) and move them to the Trash.
5. Also clear the cache for the Apple Store software update service: go to ~/Library/Caches/com.apple.storeagent/ and delete its contents.
6. Empty the Trash and restart your Mac.

After restarting, open the App Store. It will rebuild its cache and should display content normally.

Check Date, Time, and Certificates

An incorrect date or time can break the secure connection (SSL/TLS) that the App Store uses. This is especially common after a Mac has been off for a long time or if the CMOS battery is failing.

1. Open System Preferences > Date & Time.
2. Ensure “Set date and time automatically� is checked, and your time zone is correct.
3. If the date is wildly wrong, uncheck the box, set the correct date manually, then re-check it.

If that doesn’t help, the issue might be an expired intermediate certificate on older macOS versions. Apple issued a “root certificate� update for Sierra in 2019; if you haven’t installed it, the App Store may fail to load. You can download the “Apple Root Certificate Update� from Apple’s support site (requires a web browser). Install it and restart.

Reset the App Store’s Preferences

The App Store stores its settings in a property list file. If that file is corrupt, you may see a blank window. Resetting it is safe—you’ll just need to sign in again.

1. Quit the App Store.
2. Open Finder and go to ~/Library/Preferences/.
3. Find the file named com.apple.appstore.plist and move it to the Trash.
4. Also look for com.apple.storeagent.plist and trash that too.
5. Restart your Mac and open the App Store.

This forces the app to create fresh preference files, often resolving display issues.

Update macOS to the Latest Version

If you’re still on macOS Sierra, the most reliable fix is to update to a newer macOS version. Apple has released several major updates since Sierra, and the App Store is fully supported on them. Updating also brings security patches and bug fixes.

1. Back up your Mac using Time Machine or your preferred backup method.
2. Open the App Store (if it works at all) and go to the Updates tab.
3. If you see a macOS update, click “Update.� If the App Store is blank, you can download the installer from Apple’s website (search “macOS High Sierra� or later on Apple’s support page).

Note: If your Mac is too old to run a newer macOS, you may be stuck with Sierra. In that case, the cache reset and certificate fix are your best options.

Network and DNS Troubleshooting

A blank App Store can also be caused by network issues, especially if you use a VPN or a custom DNS server. Try these steps:

• Disable any VPN: Turn off VPN software and try the App Store again.
• Change DNS servers: Go to System Preferences > Network > Advanced > DNS, and add 8.8.8.8 and 8.8.4.4 (Google’s public DNS).
• Reset the network cache: Open Terminal and run sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder, then restart.

These steps clear DNS-related blocks that might prevent the App Store from loading its content.

Frequently Asked Questions

Why is my App Store blank after updating to macOS Sierra?

This often happens because the update process didn’t fully migrate the App Store’s cache or preferences. Resetting the cache as described above usually fixes it. If not, check your date/time settings and ensure you’ve installed the latest Apple root certificate.

Can I still use the App Store on macOS Sierra in 2025?

Yes, but with limitations. Apple continues to support older macOS versions for security updates for a while, but the App Store may not show all content. Some newer apps require a newer macOS, so you might not see them. The blank window issue is often due to certificate problems, which the root certificate update solves.

Will resetting the App Store cache delete my downloaded apps?

No. The cache only contains temporary data like icons and previews. Your purchased apps and downloads remain intact. You may need to sign in again, but your app library is safe.

How do I update macOS if the App Store is blank?

You can download the macOS installer directly from Apple’s website using Safari. For example, search “macOS High Sierra� on Apple’s support page and download the installer. Then run it to upgrade your system. This bypasses the App Store entirely.

Is there a terminal command to fix a blank App Store?

Yes, you can reset the App Store’s cache and preferences via Terminal. Run rm -rf ~/Library/Caches/com.apple.appstore/* and rm -rf ~/Library/Preferences/com.apple.appstore.plist, then restart. This is a quicker way to do the same steps as above, but be careful—deleting the wrong files can cause issues, so stick to these exact paths.
