Apple added a few nifty features in Yosemite. Below are ones I have found and used.
1. QuickType anywhere by pressing the ESC key while writing in any Apple app. This will bring up next word suggestions.
2. I quite like this one. If you want to move the dock from the bottom to the side then shift-click the divider bar on the dock to move it to one of the other sides of your screen.
3. Messages app has a mute options just like on iOS 8. Select details and then do not disturb.
4. It’s possible to remotely close tabs using Safari for your other devices like an iPad. From Safari on the Mac select new tab page, and click the X next to any tabs you want to close. You will see other tabs open on your other devices.
5. Spotlight does many more new things. It also does currency conversion. Just type what you need to do.
6. Sign your signature using the trackpad. Just open your document in Preview, click the signature button, and choose the trackpad option. Neat.
7. Need to help your friend with tech advise. Screen sharing is made easy via messages. So long as you both have messages running, hit details and then the screen sharing icon.
8. If you are a night owl, then Yosemite has a dark mode. System Preferences, General, Dark Menu on.
So have you any more that you would like to share?

Lack of control with public WiFi. Will explain more later.

My colleagues who don’t use Norton 360 on their MBAs have noticed when using public Wi-Fi their files seem available for sharing. We are trying to see how firewall and file sharing preferences interact.
