Just purchased a new Macbook and have installed LR CC on it so that I can use it as a companion device to my iMac to work on my photos. How do I make it so that the actions, presets, watermarks, and publish services mirror my main computer? Thanks in advance for the help.
On each computer, go into Preferences and the Presets tab. Click the button to go to the Presets folder.
On the first computer, copy the subfolders and save them on Dropbox or a USB stick or whatever, and paste them into the folder on the other computer.
There is also a fancier way using aliases. Essentially you move that Presets folder to Dropbox or some other cloud drive that both computers access, then put aliases in the regular location on each computer. This effectively mirrors your presets etc each time you open LR.
