Even though you probably use services such as icloud, dropbox, googledrive… which help you to access your stored data via the internet you still might have specific files only stored to your Mac that you might need to access when you can’t get your Mac. This can be done remotely several ways.
Apple’s back to my mac service is one option to access data remotely but you must have it setup on your Mac. First you have to open up your Mac’s system preferences and click iCloud. Make sure you are logged into your iCloud account. Enable the “back to my Mac” service. This now means that your Mac is configured with your iCloud. When you want to use this you need to make sure that your Mac is connected to the Internet as well as the computer to be active. You can ensure this by choose the energy saver preference and enable the wake for network access option. Make sure your router is up to date and allows you to have access remotely.
Back to my Mac offers several options for connecting to your remote Mac. You can access and manage your remote Mac by screen sharing, which streams the desktop view from your remote Mac to the Mac you are currently using. To enable this option you need to go to sharing system preferences, ensure that your user account is allowed access. By default administrators are give access but you can add specific users to the list. To start up your remote Mac’s screen select the Mac in your finder of another Mac configured with the same iCloud account and then click the option that allows you to share the remote Mac’s screen and open applications and documents on it.
