So I have a new M1 Mac. With a 2TB SSD and I pay for 2TB of dropbox storage.
According to the app settings on my computer and also when on dropbox.com, I am using 1.57TB of my 2TB plan.
I have an existing intel mac also with a 2TB ****** drive and when everything is synced (No smart or selective sync and everything local), that machine says the dropbox folder is taking up 1.73TB of space. A little bit more than the 1.57TB but nothing that is worth worrying about. (Well that's actually a huge difference but my other computer has much bigger files) That intel mac machine is running Dropbox 111.4.472 on Catalina.
But this is where it gets interesting. On my new M1 Macbook Air, also running 111.4.472, on ****** Sur, That dropbox folder takes over 2TB (or at least it tries to before it stops syncing becasue it runs out of space). I had to turn a 300GB folder to 'online only' to drop the dropbox folder size down to still over 1.7TB. So basically my dropbox files are taking up roughly 400GB more on my M1 mac than they actually are on dropbox.com. Which is a HUGE difference. I need help?
