Mac memory didn’t free after deleting 12GB Mac Big Sur installation package
Originally, I downloaded the Big Sur package and tried to update my Mac. However after downloading the package, the system showed there is no enough space for installing Big Sur. Then I delete that 12GB BIG SUR package in order to free the space. However after I delete it, my space is still 13GB, it remains no change! Why is that? Where is my 12GB ?
