Travelling to Macau from Mainland. visa information

Hi. I will be traveling to Hangzhou next month. I also need to go to Macau in August to attend a conference there. Could you please tell me if I can go to Macau from mainland using the visa, or do I need a separate one for Macau? Is there anyway I can apply for it from mainland? My nationality is Pakistani and currently living in the UK. Thanks in advance for your help!
