1/ Pasting text into emails faster — If you have some text on your Mac and paste it into a new email, most people select the text, choose Copy from the File menu or, faster, press the keyboard shortcut for Copy (Command-C), go to Mail, open a new message, move their cursor to the body, and then press the shortcut for Paste (Command-V).
But you can do this so much faster that I love it to bits, and I think you’ll like it too: select some text you’d like to email (or send through Messages, or tweet about, or add to Notes, etc.) and then right- or Control-click on it. When you do so, a contextual menu appears (above), and one of the available options is Share.
Pick Mail and the text you selected is inserted right into the body of an email, ready for you to send.
If you select Messages or a few of the other options, you get a little box overlay for you to compose and edit as you see fit.
This works in quite a few places around the operating system, including in Safari and Mail, so if you need to forward only a bit of a message to someone else, for example, you can do so.
2/ Sending your whole Contacts list as a file — Unfortunately, there’s no obvious or easy way to do this, but it is possible. Open the Contacts app, and select the All Contacts option from the left-hand list. (If you don’t see the list this item crowns on the left of Contacts, choose View>Show Groups or press Command-1.)
Now click on any member to select a single card, and then press Command-A to select them all. Once they’re all highlighted, go up to the File menu and choose Export.
You have to be sure to choose Export vCard, and not Contacts Archive. If you pick the latter, whomever you send the file to will have their own contacts list replaced when they attempt to import your stuff!
3/ Send specific contacts in a file — You can also pick a different subset of your contacts (a Group) and follow the same process, above.
4/ Solving Bluetooth issues — A combination of saturation of wifi frequencies and Bluetooth’s functional limits can make it work less well than you’d hope. You can try to reduce competing use of the spectrum — if you have a baby monitor, remote-door bell, older cordless phone, or other wireless stuff that uses 2.4 GHz, you might move or replace it. (Check the labels and manuals for frequencies used.)
A Wi-Fi base station too close to your Bluetooth equipment and computer can also be a problem. Most consumer Wi-Fi access points uses the 2.4GHz band, and many also use 5GHz. They use a swath of 2.4 GHz that can deny about one-quarter to one-third of the band to nearby Bluetooth devices. If you’re in a highly congested area, like an apartment building or office block, you may have many Wi-Fi base stations and devices active: you simply can’t avoid it.
The Bluetooth controller on a Mac may not be able to keep up. The official Bluetooth specifications say seven is the maximum number of Bluetooth devices that can be connected to any Mac at once, but three or four devices is a practical limit, depending on the types of devices since some require more Bluetooth data – they’re more demanding than other devices. Data-intensive devices might reduce the total number of devices that can be active at the same time.
If you can’t make the Bluetooth work reliably and there’s an audio input, you might switch to running an audio cable for more reliability.
5/ The Dock and Spaces — If you’ve set an app to run in a specific Space, it’s easy to double-click that app in the Dock and be taken quickly to the space that contains that app. (To define which Space an app will run in, right- click the app in the Dock and select Options.)
You can avoid having to double-click the running app in the dock to jump to the desired Space. Go to System Preferences>Mission Control. Check the box ‘When switching to an application, switch to a Space with open windows for the application.’
This has the side effect of allowing a single-click on the running app in the Dock to switch to the Space that contains that app. If you have a fast GPU, that jump happens quickly, and it’s virtually transparent to your work flow.
