Q: Macbook Air won't boot after installing El Capitan
Hello all,
This weekend i have updated my Macbook Air(2011) to El Capitan. Somehow after the update the macbook is super slow. I was able to start up in safe mode. I have tried to reinstall El Capitan. Worked, although the Macbook still was super slow. I've checked the activity monitor and the task kernel_task was using 300+% of the CPU.
Next step was to reboot in recovery mode, erase the HDD and instal from an external USB drive. Using terminal, on another old macbook(2008), i have created a Yosemite install USB Drive.
Now the problem is that the Macbook does not have a OSX installed and i can't reach the alternative USB instal drive. During start up i press the option key, select the USB drive to start up, BUT it takes longer then an hour to get past the Apple sign and progress bar... At the moment i have not been able to start the installation process...
Who can help?? I'm getting frustrated right at the moment, since it already took me 2 days trying to fix the issue. Please help!! Any suggestions?
Thanks in advance!!
MacBook Air, OS X Yosemite (10.10.5)
