Pink Waters Posted March 11, 2018 Share Posted March 11, 2018 Hello guys, I have high sierra set up and ready, but I notice that it is very laggy, and apps and games takes significant time to load. I did a black magic disk speed test and it gives me average read/write speed around 30mb isn't that low ? any help will be appreciated. my info in the signature.
