1/ Insert media directly into documents — In various Apple software, in the desktop user interface, and in some third-party apps, there’s a labeled option to browse your main and alternate media library, including offering options for both iPhoto and Photos if you’ve retained libraries in both formats. This lets you directly insert, say, an image into your Pages document without hunting separately through your iPhoto or Photos collection.
In your Open, Place or Insert dialogue box, just scroll down in the sidebar on the right and you should find a Media section that lists Music, Photos, and Movies. Click Photos, and you’re further offered supported apps. I have one older app, my email client, that only shows iPhoto and Photo Booth. However, Firefox and Safari both also list Photos as an option. Select the app type, and you’ll be able to drill down to years, moments, albums, collections, and other divisions depending on the library type.
2/ Sort files in the Mac OS Finder — You can sort items in a Finder window alphabetically by clicking the Name field at the top of folders when you are in the list view. An upward-pointing arrow following Name indicates sorting alphabetically with numbers first, then A to Z; click again to swap to downwards, and it’s sorted Z to A, then reverse numeric order. You can also select the menu item View >Arrange By>Name.
Click the Arrange By/Sort By icon in the Finder window toolbar (if that icon is displayed) and choose Name.
3/ Arrange By — You can also experiment with Arrange By, which groups items into larger categories, coupled with Sort By. In a downloads folder, for instance, you can have Sort By set to descending chronology (oldest files first) using Date Added, and then Arrange By Set to Name. This groups items into Today, Yesterday, Previous 7 Days, Previous 30 Days, and months and years after that (as long as any items fit into each date group). Within each group, the items are alphabetised to make them easier to read through. This even works across the desktop, if you have files strewn all over the place (which you shouldn’t have).
4/ Start Dictation with a spoken word — If you use Dictation (System Preferences>Dictation & Speech) to talk while your Mac types out like your own personal typist, you can get the Dictation feature to tell your Mac to bold a paragraph, delete a sentence, or replace a word. With El Capitan, you can now set your Mac so it will begin accepting dictation upon a spoken command. Open System Preferences and go to Accessibility.
Choose Dictation from the sidebar. Enable the Dictation & Speech feature.
Click the ‘Enable the dictation keyword phrase’ and come up with a phrase or word you wouldn’t say by mistake in front of your Mac. (More info here.)
5/ Turn off inline email attachments — When you insert an image or a single-page PDF into an email you’re about to send, the item plops itself right in the body of your email. Luckily, the command that disables this feature is working again in El Capitan. To do so, open the Terminal program (it’s within Applications > Utilities) and copy and paste the following text into its window:
defaults write com.apple.mail DisableInlineAttachmentViewing -bool YES
Press your Return key on your keyboard, and from then your attachments will be icons.
If you decide you don’t like this setup, you can reverse the command by changing the last word:
defaults write com.apple.mail DisableInlineAttachmentViewing -bool NO
And that’s all there is to it. But be aware that if you change this on your own machine, it won’t necessarily affect how your recipients see things. This command is solely for your own email-attachment happiness
