Troubleshooting push notification communications between OS X Server and Apple’s Push Notification can be a challenge. Especially with Profile Manager. One great tip I’ve learned over the years is that the APNS daemon, apsd, has a debug mode. To enable APNS debug logging, run these commands: defaults write /Library/Preferences/com.apple.apsd APSLogLevel -int 7 defaults write /Library/Preferences/com.apple.apsd APSWriteLogs -bool TRUE killall apsd Then use tail -f to watch the apsd.log file at /Library/Logs/apsd.log. Be wary, as this can fill up your system. So to disable, use these commands: defaults write /Library/Preferences/com.apple.apsd APSWriteLogs -bool FALSE defaults delete /Library/Preferences/com.apple.apsd APSLogLevel killall apsd
