Not able to create Amazon EC2 Mac instance

Question

I am not able create Amazon EC2 Mac instance, followed the below documentation.

https://aws.amazon.com/getting-started/hands-on/launch-connect-to-amazon-ec2-mac-instance/

I see the below error, could any one suggest what could be the cause.

The number of Dedicated hosts you've requested (1) would bring your total up to 1 for the specified group of instance types (mac1). This exceeds your current limit of 0. If you've recently released Dedicated hosts, it may take some time for them to stop counting towards your limit. Try allocating your hosts again after a few minutes. Please visit http://aws.amazon.com/contact-us/ec2-request to request an adjustment to this limit.

Answer

A similar case is reported on GitHub below, and the cause seems to be the quota for Maximum number of running dedicated mac1 hosts. [1].

The number of Dedicated hosts you've requested (1) would bring your total up to 2 for the specified group of instance types (mac1). This exceeds your current limit of 1. - Issue #4 - DanielRDias/terraform-aws-dedicated-host

Perhaps the following quota is 0 in your account.

・`Maximum number of running dedicated mac1 hosts.`

In my account, the above quota is 0.  
If you would like to increase your quota, please visit the following support URL or request it from the service quota console.
