I am a long time PC guy but my surface pro took a fall to an untimely death so I decided to try MacBook. Still learning curve. My biggest issue is easily accessing my work drop box, personal Dropbox, and one drive in Microsoft Office and when trying to attach to emails. I cannot seem to seamlessly get them to show up, or it's only certain folders that I have saved to computer. I always like that on PC from email I could attach files from the cloud based storage.

Any advice appreciated.

Been on Macs for years and never had a Dropbox issue. Not sure if needing access to multiple accounts might be the issue.

I'm assuming you've installed the app and have a local Dropbox folder on your desktop or somewhere else?

Yeah I think it's the multiple accounts issue. It wasnt a problem on PC but cannot seem to easily get between the two on the Mac...I did download the app

Gotcha, I've always just had one account so haven't encountered that issue.

Quick search turned up this, don't know if it helps:
