Why could Dropbox suddenly be so slow at launch? Do I have to check the LAN-sync option or not. What does it do anyways? I never had any troubles with Dropbox until a few weeks ago when iOS 9 got released - Dropbox also updated the iOS app to make them compatible to iOS 9. I know one probably has nothing to do with the other ( Mac app ) version but still. It's crazy that around that date those problems started to show out of the blue. Every time when I restart my Mac and log in with my Admin account it takes Dropbox about 7 minutes to 10 minutes to startup and get ready. In Finder I can get my Dropbox files, no problem there but still I hear my Mac loading and loading and loading. When I press the menu bar app I notice the Sync symbol says starting and keeps spinning around. This takes up about 7 tot 10 minutes before it's ready. I keep my Mac very lean and clean, never install software just for fun or without knowing the developer is rocking solid! Also, it's not like some other apps are starting at the same time what could prevent Dropbox from running. I only have three apps ( 1Password, Dropbox and Annotate ) those start at launch. Anyone else notice this problem as of late or am I the only one here. This is kinda annoying because me loves Dropbox so much..
