If your mac Startup disk isn't overloaded with Dropbox Sync files then your Mac's system will probably need a good clean-up. The Easy Way to Clear Space on Mac Startup Disk - CleanMyMac In my case, I managed to save over 160GB on my Mac Book Pro with this simple tweak. Once Dropbox has reindexed/synced your folders you will find that you have potentially saved loads of space on your Mac Hard Drive and the “Your startup disk is almost full” prompt on your Mac will disappear. Any folders you de-selected will be removed from your hard drive, but will still be available through the website and on any computers linked to your Dropbox account. Uncheck any folders that you don't need to sync to your computer's hard drive. The folders with a check next to them will be synced to your computer. A window will appear with a list of all the top-level folders in your Dropbox folder.

Here's how to free up space on your Mac hard drive by selectively choosing which folders (the ones you access regularly) to include in your local storage. If you are using Dropbox as a file archive/repository then the potential usage of Dropbox local storage could be enormous. Dropbox does this to speed up file access and syncing, but actually what it's also potentially doing is overloading your limited Hard Drive space. So if like me you initially thought that all your files were 100% 'In the Cloud' then you were wrong. This is because Dropbox stores files locally as well as remotely on Dropbox itself. If you have Dropbox and are getting the prompt ' Your startup disk is almost full' on a Mac then it's quite likely that Dropbox is the culprit.
