Hello there! Try the steps below to reset your connection. Then attempt to connect to the app store again.
This did not correct the situation. It still says "Connection Failed" when I attempt to purchase something from the App Store.
Ok try the steps below to reset the apps store prefrences.
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type this exactly as you see it here:
Move these files from the Preferences folder to the Trash.
Now do the same for: ~/Library/Caches/com.apple.appstore/Cache.db
Move the Cache.db to the Trash.
Try the App Store.
If that still doesnt work try the below steps.
It still has the same response. I did each of those (actually, the key chain was an answer I had previously found when researching this issue). I have reset the computer also following those changes. I can access the app store, but whenever communication is required that goes through username and password, it does not work.
Yes, those both work.
Want to try this one instead: I get this error all of the time:
The system extension “/System/Library/Extensions/CDSDAudioCaptureSupport.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.
Okay. I did that. Is there anything more I need to do?
