Top 6 Ways To Fix App Store Sign In Problem On Mac

The App Store used to be an easy to use app on my Mac. Until the day I needed to download a task manager app, but the App Store wouldn’t allow it. There was an “Unable to connect to the App Store” message in the application window. I finally downloaded the app, but not after trying some of the troubleshooting methods below.

The problem is mainly related to the network. Other times, your Mac’s date and time settings can also affect the performance of the App Store. We have listed six different solutions to this error below. Check them.

1. Check the internet connection

First of all: is your internet connection working properly? As mentioned earlier, you will most likely come across this error due to poor internet connection. To be safe, we recommend that you run the following troubleshooting tests. First, launch Safari or your favorite Mac browser and check if you can access any website without issue. If you can access multiple web pages on the browser, your internet connection is good. Otherwise, turn off your Mac’s Wi-Fi and turn it back on.

You can also restart the Wi-Fi router or implement some of the Wi-Fi signal troubleshooting tips to increase your router’s network signal. For wired Internet connectivity, unplug the Ethernet cable from your Mac (or USB hub) and plug it back in to reestablish the Internet connection. Finally, you can also try to connect your Mac to another wired / wireless network and check if you can now use the App Store.

If your Macbook fails to connect to the App Store, forcing the app to close and relaunch may restore its normal functionality. There are several ways to force quit an app on your Mac. Check them out below.

Is the App Store online

The error may have nothing to do with your network, device configurations, or software bugs. Sometimes it’s just Apple. If the App Store servers are down, you cannot access the store. Although this rarely happens, it is a reasonable possibility. If the error persists, we recommend that you visit Apple’s System Status page to check if the App Store server is online and accessible. You can also restart the device and try to access the App Store again.
