Before you start
10 min
Plug in the Mac and keep it on Wi‑Fi until the end.
Check where your OneDrive app came from: if it was installed from the Mac App Store, delete it and install the one from microsoft.com/onedrive/download. Backup (step 4) only works with that version.
Open onedrive.live.com with your personal account. Note how much space it uses (shown at the bottom left).
Make sure your Mac has at least that much free space: Apple menu → About This Mac → More Info → Storage.
Not enough free space on the Mac?Do step 1 one folder at a time instead of everything at once.

Copy personal files into MHMG
5 min + waiting
Open Finder. In the left sidebar you see two OneDrive folders: OneDrive – Personal and OneDrive – (your company name).
Inside the MHMG one, create a new folder: ⇧⌘N. Name it From Personal OneDrive.
Open OneDrive – Personal. Select everything: ⌘A. Copy: ⌘C.
Open the new From Personal OneDrive folder. Paste: ⌘V.
Wait. Click the cloud icon in the top menu bar. When it says the files are up to date, the copy is done. Large libraries can take hours; leave the Mac on.
Copy and paste. Do not drag.Dragging can move files instead of copying them. Copy keeps the originals safe in the personal account until the end.
Copy from Personal, paste into the new folder inside MHMG.
Two special casesIf you use Personal Vault, unlock it at onedrive.live.com and copy those files too. Anything you shared from the personal account: share it again from MHMG.

Check that everything arrived
5 min
In Finder, click OneDrive – Personal once and press ⌘I. Write down the number of items.
Do the same on the From Personal OneDrive folder.
The two numbers must match. Open 3 or 4 files at random from the new folder to be sure they open.
Same number of items on both sides = copy complete.
Numbers don't match?Stop here and send Igor a screenshot of both windows. Do not go to step 3.

Remove the personal account from the Mac
2 min

Click Help & Settings (or the ⋯ button) → Preferences.
Open the Account tab. Next to your personal account, click Unlink this Mac.

Nothing is deleted.The personal files stay online at onedrive.live.com. Keep that account as it is for 30 days as a safety net.

5 min

Open the Backup tab → Manage backup.
Select Desktop and Documents → Start backup.
When it finishes, each folder shows “Files backed up”.
What is backed up: Desktop and Documents only.Not Downloads, not the Photos app library, not apps. From now on, save your work on the Desktop, in Documents, or directly in OneDrive – MHMG. Move anything important from Downloads into Documents.
Backup option is grey or blocked?It is a company setting. Send Igor a screenshot.

After 30 days
5 min
On your iPhone and iPad, open the OneDrive app and sign out of the personal account, so nothing new goes there.
If nothing was missing in these 30 days, you can stop paying for the personal Microsoft 365 plan (if you have one).
