Well El capitan has surely held up to my expectations of performance. I am not a pro user maybe that is the case why. However El capitan seems so much more stable than Yosemite which to me until 10.10.4 was a complete disaster. I used to get somewhere around 5-6 and a half hours with web browsing with my MBA 11" 2014 version and now that has increased to its actual potential of about 8-9 hours of web browsing. Performance has increased massively too. I used to get around 180-250 write speeds at best with Yosemite. Now with el capitan this is the result. I used to get this kind of write speeds when I freshly bought my mac installed with Yosemite. This is a huge bump and very welcome performance improvement for me really. However I have been facing some issues lately which I hope you guys here can help me solve. 1. Maybe I am doing something wrong but I am unable to use the checklist in notes app. The checklist button is just dimmed out and not pressable. i am unable to bring the checklist option with the shortcut either. Maybe there is something I need to do which I may have missed out for this? Please help on this. 2. This is actually a big issue for me because it hinders my normal browsing experience. Whenever I take my mouse pointer towards the leftwards edge, the favourites bar pops on everytime. And I frequently experience this due to my browsing habits probably. Please help me solve this issue.
