# Your maximum App ID limit has been reached. You may create up to 10 App IDs every 7 days.

> Apple lets a free account make 10 App IDs a week. Wait a few days, or build Mobster's helper with a paid developer team.

You see this: `xcodebuild` prints this as `Communication with Apple failed` while it signs Mobster's helper. Mobster shows `Your free Apple Account can make 10 app IDs a week.`

## Why it happens

Signing the helper needs an App ID, and a free Apple Account may create up to 10 in 7 days.

## Fix

1. Wait a few days for the limit to reset.
2. Or choose a paid developer team in Mobster's setup so the helper builds under that team.
3. Build again from Mobster for Mac.

## Check it worked

The build finishes and `mobster doctor` prints no `✗` line for the runner.
