macOS App Store Error 500 — Cannot Connect Fix

What Does This Error Mean?

App Store error 500 on macOS means the App Store received an unexpected response from Apple's servers — essentially a server-side error. This could be on Apple's end (a temporary outage), or it could be caused by network issues on your Mac such as DNS problems, a proxy, or incorrect date and time settings.

Affected Models

MacBook Air
MacBook Pro
iMac
Mac Mini
Mac Pro
Mac Studio

Common Causes

Apple's App Store servers are temporarily down or experiencing high load
Your Mac's date and time settings are incorrect, causing server communication errors
A VPN or proxy server is interfering with App Store connections
DNS settings are resolving Apple's servers to incorrect addresses
The App Store cache on your Mac is corrupted and causing bad requests to the server

How to Fix It

Check Apple's system status first. Visit apple.com/support/systemstatus in your browser. Look for any yellow or red indicators next to App Store.

If Apple's servers are having issues, there is nothing to fix on your end — just wait 30–60 minutes and try again.
Verify your Mac's date and time. Go to System Settings > General > Date and Time. Turn on 'Set time and date automatically' and ensure the time zone is correct.

Incorrect time causes SSL certificate verification failures that look like server errors.
Disable any VPN or proxy. If you are using a VPN, disconnect it and try the App Store again. Go to System Settings > Network and ensure no proxy is configured under Proxies.

VPNs and proxies can route App Store traffic through servers Apple's infrastructure rejects.
Clear the App Store cache. Open Terminal (Applications > Utilities > Terminal) and type: rm -rf ~/Library/Caches/com.apple.appstore — press Enter, then restart the App Store.

This deletes the App Store's cached data. It rebuilds automatically when the App Store reopens.
Change your DNS to Google's public DNS. Go to System Settings > Network, select your connection, click Details, go to DNS, and add 8.8.8.8 and 8.8.4.4. Remove any existing DNS servers.

If your ISP's DNS is returning bad results for Apple servers, using a public DNS like Google's often resolves App Store errors.

When to Call a Professional

App Store error 500 is almost always fixable without professional help. If the App Store consistently fails while all other internet services work fine, Apple Support can investigate your account for any flags or restrictions.

Frequently Asked Questions

Is error 500 always Apple's fault?

Not always. While a 500 error typically means a server-side problem, the App Store also returns 500 errors when your Mac sends a malformed request — which can happen due to corrupted cache, wrong time settings, or network interference. Check Apple's system status page first, then try the cache and DNS fixes.

Why does the wrong date and time affect the App Store?

The App Store communicates over HTTPS — a secure, encrypted connection. HTTPS certificates have valid date ranges, and if your Mac's clock is significantly off, the certificate appears expired or not yet valid. The connection is rejected as a security measure, which shows up as a server error on your end.

I can browse the web fine but the App Store still fails. Why?

The App Store uses its own API connections that are separate from regular web browsing. A VPN, DNS issue, or cached session data can block App Store connections while leaving regular websites unaffected. Clearing the App Store cache and checking DNS settings specifically targets these App Store API issues.
