I'm using early 2011 i5 MacBook Pro. I upgraded to Sierra but the speakers and USB are not working and the system is very slow. Then iI restarted my Mac with (Commandcmd+Optionalt/opt+R) in the utilitiesto Recovery Mode. I cleaned my hard drive now I tried to reinstall Sierra but in the logs I saw it is downloading from the Internet. I gave quit tostopped the installation then Iand restarted my Mac after. After the Apple logo it shows nothing like(0)but the 🚫.
Then I boot my USB drive to El Capitan but it is installing Sierra from the Internet... it takes days to download with my internet speed.
Please help me to solve this problem.
