Hello I downloaded the Serato Sample plug in earlier to try the trial and see if I like it. I have an iMac running Sierra 10.12.4 with 8GB RAM. I have download the Serato Sample 1.1 .dmg file several different times. Each different time when I try to open and install it will stall out while verifying "Serato Sample 1.1.dmg" usually about about 55 to 60% in. To my knowledge my iMac meets the required specs. Please help! Thanks :)
