Getting tired of Spotlight in Yosemite being useless in comparison to Mavericks? Edit its shortcut to pop the Finder search bar instead. Bit of a poor cousin to Spotlight in earlier versions of OSX which were much better: didn't block the screen, allowed you to open the enclosing folder, and more.
Apple Menu > System Preferences > Spotlight. Change the keyboard shortcut you are familiar with to open the Finder Search window instead.
Now it'll open like below instead, and the results are easier to deal with...
Also consider replacing Spotlight functionality with Alfred. The freeware version is okay, I haven't yet been keen on splashing oout £17 for the PowerPack...
You can use Apple's scripting language for some very useful tasks. Here I am gathering all of the mess in my Downloads folder into one folder and labelling the folder with today's date. Select the following text:
setfoldernameto ("Downloads " & short date stringof (current date))
movefolder (docsfolder & foldername) to (path todownloads folder)
Open the Script Editor from your Utilities folder and paste the text into the 'untitled' window. Click "Compile" and then click Run if you would like to test it directly. You can save the script as an application, placing that somewhere convenient to run when your downloads folder clogs up again. Choose File Menu... Save, and from the File Format menu choose Application. The script works by first creating a folder in the Documents folder, then moves all the contents of the Downloads folder there, then moves that folder back into Downloads.
Like many others I've been frustrated that the DropBox contextual menu has disappeared in OSX Yosemite 10.10 and doesn't seem to be getting updated in a hurry. Here we can duplicate the DropBox contextual menu's action and even improve on it at the same time, by using the Automator application to create an OSX service, which will have the function of moving a file or folder to your DropBox and then reveal the item for further action.
Open Automator from the Applications folder
Choose to create a new Service
Choose the options Service receives selected:Files or Folders in Finder
Drag the Move Finder Items action from the middle column into your workflow window at right
Select your DropBox folder for the Move Finder Items To: option
Drag the Reveal Finder Items action from the middle column into your workflow window at right
Save the workflow from the File Menu, naming it Move to DropBox. The file when saved ends up in your user's Library/Services folder. You can edit it if you want to change the way it works, or duplicate it and target specific project folders.
Then test it out: right-click a file or folder in the Finder, and choose Move to DropBox from the Services sub-menu. Note that if a file with the same name already exists at the destnation no action will occur.
