Cloud accounts · Using your accounts
Can I stop one cloud account from showing in Finder?
Short answer: Yes. In Cloud Accounts, open the Cloud Drive tab and switch off that account. Each source has its own switch. The account keeps working everywhere else; it just doesn't appear in Finder.
Yes. Open Cloud Accounts, go to the Cloud Drive tab, and switch off the account in the list of sources. Each account and device has its own on/off switch, and changing one rebuilds the drive without disturbing the others.
Hiding an account from Finder doesn't remove it — it still works in Data Transfers, Data Parking and backups. To turn the Finder location off entirely, use the main switch on the same tab.
