visit Macau for Pakistani but live in Malaysia

Ahsan, yes, you can apply for it from Malaysia. You need to provide those documents: copy of your passport, a fully completed application form attached with a passport-style photo, proof of your financial support, transportation and accommodation arrangement, your residence permit in Malaysia, as well as your travel plan.

Ok got your point one more thing will you tell me that when I get visa I can visit to HK or not on Macau visa.

No, you cannot. You need to apply for a HK visa in advance if you want to visit HK.
