Then Click “Download” button to download the certificate (.cer file) you’ve created just now. – Double click the downloaded file to install the certificate into Keychain Access on your Mac.

Step 7: On your Mac, go to “Keychain”, look for the certificate you have just installed. If unsure which certificate is the correct one, it should start with “Apple Production IOS Push Services:” followed by your app’s bundle ID.

Step 8: Expand the certificate, you should see the private key with either your name or your company name. Select both items by using the “Select” key on your keyboard, right click (or cmd-click if you use a single button mouse), choose “Export 2 items”, like Below:

Then save the p12 file with name “pushcert.p12” to your Desktop – now you will be prompted to enter a password to protect it, you can either click Enter to skip the password or enter a password you desire.

Step 9: Now the most difficult part – open “Terminal” on your Mac, and run the following commands:

cd
cd Desktop
openssl pkcs12 -in pushcert.p12 -out pushcert.pem -nodes -clcerts

Step 10: Remove pushcert.p12 from Desktop to avoid mis-uploading it to Build Your Own area. Open “Terminal” on your Mac, and run the following commands:

cd
cd Desktop
rm pushcert.p12

Now you have successfully created an Apple Push Notification Certificate (.pem file)! You will need to upload this file to our Build Your Own area later on. 🙂
