MacMost: Yosemite

Using Spotlight Search
10/29/14

Spotlight Search has been completely redesigned in Yosemite from the old Spotlight Menu function. You can still search for files, but in addition you'll get information from the Internet such as movie times, Wikipedia, maps and recommended web pages. You can also do unit and currency conversions and math. File searches can be filtered by kind and date. You can also use logical functions like OR and - (not) to get better results. Find out all you can do with Spotlight Search in Yosemite.

Using Mail Markup
10/27/14
With OS X Yosemite you can mark up images and PDF files right inside of the Mail composition window. This can make it easy to send notes and revisions back and forth between people working on projects. You can also add signatures to PDFs easily in a reply. The same tools are available in the Preview app outside of Mail. In the future, Apple and third-parties can add more extensions like Markup.
RSS Subscriptions In Safari
10/22/14
With Yosemite and iOS 8 you can once again use RSS feeds. The left sidebar allows you to add the feed for a web site you are viewing. You can add many feeds and see an aggregated list of items from those feeds, as well as from social media like Twitter, Facebook and LinkedIn. This works both in Yosemite on the Mac and iOS 8 on the iPad.
Using iCloud Drive
10/20/14
With OS X Yosemite you can use iCloud Drive as a place to store your files. iCloud Drive syncs between Macs and the files can also be accessed by the appropriate apps in iOS 8 on the iPhone and iPad. You can also create your own folders in iCloud Drive on Yosemite and access files on iOS 8 from outside of the normal app folder for that type of document. iCloud Drive can also be used to store other types of files, even if the app does not support iCloud Drive. On iOS 8, you can import media from iCloud Drive and export files to it as well.

There are hundreds of keyboard shortcuts for Mac users. There are Mission Control shortcuts, Finder shortcuts, system shortcuts, application shortcuts and more. Many you can find by just looking through the menu bar for that application. You can find system ones by looking in the System Preferences under Keyboard.

But some keyboard shortcuts are more useful than others. And some are harder to remember than others.
So MacMost has compiled a list of our top “power user” keyboard shortcuts for Mac OS X 10.10 (Yosemite). Here they all are on a single PDF page, downloadable and printable: The MacMost Yosemite Power User Keyboard Shortcuts. Download it and pass it along!
