OneDrive on MacOS Eating Up Huge Amounts of Storage
Hardware: M3 Max MacBook Pro 14" (14 Core CPU/30 Core GPU, 36GB, 1TB) Software: MacOS 26.4 OneDrive Version: 26.002.0105 (Mac App Store version) I use OneDrive to sync files between my PC (primarily used for gaming) and my MacBook Pro (pretty much everything else) mostly because I'm paying for Office 365. I've noticed in the MacOS storage storage section of settings, there's something taking up ~170 GB of storage. Digging around, I found the culprit: Library>Cloud Storage>OneDrive is currently sucking up ~143GB of storage. It seems like OneDrive is keeping large numbers of files stores locally. Legitimately have no idea why this is the way it is, or how to solve the issue (or if there is even a resolution). Like, why bother with files on demand when the application is going to store half the files locally, anyway?
Enabling OneDrive Health Sync
Hello, once again being victimized by Microsoft 😒 Have a series of users reporting constant sync errors. We've reached out to Microsoft technical support and they just successively told us it was garbage and not to use it. Anyway, trying to get the Sync Health Dashboard to work, based off this document: https://learn.microsoft.com/en-us/sharepoint/sync-health?tabs=windows It's one of those Microsoft documents that the community CAN'T edit, so of course - it's out of date and incorrect. From what I can figure, based on research from other sources, most of this process is now arbitrary, and you have to create a 'EnableSyncAdminReport' in some policy location in the registry. Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OneDrive < already exists, but not referenced by documentation Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\OneDrive < key doesn't exist, but is referenced by documentation. but this sorta 'try it and see' methodology really upsets me. Anyone have any insight to this, and why the documentation team fails to update the documentation, or whether this process will work or not?
anyone else keeping files on two clouds just in case onedrive goes down?
hey everyone seen a few posts here about files going missing or sync just stopping randomly and it got me thinking about how much we all just trust one cloud completely my situation is i have onedrive for work, google drive for stuff i share with clients, and dropbox still has old project files from years ago that i never got around to moving. so im constantly opening three different tabs just to find one file. pretty annoying honestly couple months back onedrive just didnt sync a folder for a few days. i only found out when i needed something on another laptop. nothing was actually lost but it made me a bit nervous about having everything in one place with no backup plan so i started looking for something that just shows all three drives together. found a tool called All Cloud Hub (allcloudhub.com) and been using it since. it puts all your connected drives into one dashboard so you can search across all of them at once instead of checking each one separately. you can also move files directly from onedrive to google drive without downloading anything to your computer first which saves a lot of time it connects through oauth so your login details never go to them and your files stay in your own accounts. nothing gets copied to their servers. free plan covers up to 3 cloud accounts which was enough for me wont fix microsofts sync issues obviously but at least if something breaks on one side your files are still somewhere else does anyone else do something like this or is it just me being paranoid lol
Critical Sync Failure on macOS: Local data ignores Sync Engine unless manually opened
Environment: OS: macOS 15.7.4 (Sequoia) OneDrive Version: v.25.224.1116 File Provider: Apple File Provider (CloudStorage) framework The Problem: I am experiencing a persistent failure where OneDrive for Mac refuses to index or upload files moved into the local directory. The sync only triggers if I manually open each file or subdirectory, making bulk data management impossible. Files copied into ~/Library/CloudStorage/OneDrive-Personal remain in a "Pending" or "Online-only" state indefinitely. Standard "User Intent" triggers (opening the file) work, but the background daemon (fileproviderd) does not acknowledge local filesystem changes (FSEvents). Troubleshooting Already Attempted: 1) Standard Resets: Ran ResetOneDriveApp.command and OneDrive.app/Contents/MacOS/OneDrive /reset. 2) CLI Overrides: Attempted open /Applications/OneDrive.app --args -Settings (only opens Finder). 3) Metadata Clearing: Used xattr -rc to strip extended attributes and find . -exec touch {} to force timestamps; neither triggered the sync engine. 4) FileProvider Utility: fileproviderctl materialize is unresponsive or deprecated in this build. 5) Re-mounting: Attempted /unmount and manual cache clearing in Group Containers, but the UI remains "headless"—the Menu bar icon opens a Finder window instead of the Settings menu. Current State: OneDrive is functionally a "Pull-only" service. It downloads changes made on other devices, but will not "Push" local changes unless I recursively open every directory manually. Question: Is there a known method to force a full re-index of the File Provider local database when the standard reset flags fail to re-register the FSEvents observer?URGENT: OneDrive Restore Completed but Files Missing – No Engineer Assigned Since Dec 27
Hello, I am posting here as a last resort after more than 6 weeks of unresolved support. On December 26, 2025, I accidentally deleted a large number of files and emptied the Recycle Bin. On December 27, 2025, I immediately initiated a full OneDrive restore to a snapshot from December 19, 2025. The restore job shows: • Restore status: Completed • Thousands of restore events processed • However, hundreds of events failed (Save Conflict, Item Not Found in Recycle Bin) My storage usage dropped significantly (from 10+ GB to ~2.7 GB), and thousands of photos never reappeared. Restore logs show: • Multiple “Save Conflict” errors • Multiple “Item Not Found in Recycle Bin” errors • Backend SharePoint references (SPException) I opened an official support case on December 27, 2025. The current status still says: “A support agent is being assigned to your request.” No OneDrive engineer has contacted me in over a month. I am a paying Microsoft 365 subscriber. My questions: 1. Is there a way to confirm whether backend snapshot data still exists? 2. Does “Restore Completed” guarantee that the backend restore fully executed? 3. Can Save Conflict errors prevent large portions of data from being re-materialized? 4. Is escalation to the OneDrive backend team still possible beyond front-line support? This is not a basic user error case. The restore logs clearly show backend-level operations. If anyone from the OneDrive engineering team is monitoring this forum, I am urgently requesting technical escalation. Thank you.OneDrive stuck on "signing in"
Hi, I'm trying to use Onedrive and Onenote, but it seems to be really terrible 50% of the time. Sometimes when I log on my pc, it says I have to log in, and in doing so, is stuck on a "signing in" loop, until it says some error code about me not having an internet connection. Here's what I've tried: 1. Close and open Onedrive 2. Removing auth from the pc and adding it again 3. Reinstalling Onedrive 4. Change Wi-Fi 5. Do a /reset in Windows run AND cmd 6. Update drivers 7. Install the newest Onedrive from the website 8. Try the app-version found in Windows Store What am I supposed to do? I don't want to restart my pc every time it doesn't work, that's a terrible fix.Sharepoint Shortcut to OneDrive
Hi, We’ve been using “Add shortcut to OneDrive” from SharePoint instead of the “Sync” option. Recently, however, some users have reported missing files. After investigating, I noticed that the shortcut appears to have been converted into a local copy in the user’s OneDrive. I realized this because the folder no longer shows the shared (people) icon, and I’m able to re-add the shortcut without any errors. Normally, if a shortcut already exists, SharePoint would display an error indicating that the shortcut is already present in OneDrive. Has anyone else experienced this issue? Thanks, Sur
Files-On-Demand status on OneDrive for Mac is confusing
Setting the scene: I'm on an M1 MacBook Pro, MacOS Sequoia 15.5, OneDrive for Mac v.26.017.0126.0002 (standalone) Mystery #1: Okay, so I've got a folder chock full of large files (all neatly placed in nested subfolders, of course). This one folder totals about 400 GB, in fact. For obvious reasons I had set that folder to be cloud-only by electing it and choosing 'Free Up Space' from the contextual menu. It took a while to unload all that data but eventually my finder window showed '900 GB available' instead of '500 GB available', which is what it has said previously. Great. Except that when I looked at the actual folder in ~/Library/CloudStorage and used Cmd-i to 'Get info' on that folder, the info window said that the folder size was… 400GB. The third party disk analysis tool Daisy Disk also reported that folder as being 400 GB in size. Surely if the files have been released back to the cloud and only placeholder 'stubs' remain on the local file system, that folder should have a much smaller size. So what's up? Mystery #2: I want to make a cloned copy of my Mac for backup purposes and I want to include my OneDrive content in that backup (in case the Microsoft OneDrive servers explode, or get overrun by fire ants, or something). I know that there's no point backing up the placeholder stubs — they've got no real data in them (or do they? See Mystery #1) so I select that big old 400GB folder and select 'Always keep on this device'. The menubar icon shows activity, and I can see the individual files downloading if I click that menubar icon. About 20 hours later (because 400 GB) OneDrive finally reports 'Your files are synced'. And the Finder, sure enough, tells me that I now only have 500GB available, not 900 GB. HOWEVER, that folder, and each folder and file inside that folder, has both a 'downloaded locally' checkmark icon (dark grey) AND a 'in the cloud' icon (cloud with a downward arrow in it). Cmd-i (Get info) on one of the subfolders reports a theoretical size for that subfolder of ~230 GB but with only 11.4 MB on disk. If I click on the cloud-with arrow icon then OneDrive seems to redownload the file or folder-and-contents. At least I assume that that's what it's doing; this time the OneDrive menubar icon does NOT show activity, nor do any files show as being processed/downloaded if I open up that menubar window. But whatever the process is, it seems to take about as long as I would expect the download to take and the cloud-with-arrow icon turns into one of those 'time-remaining' icons that looks like a pie chart being filled up. So far I've only done this with small folders as an experiment, because if I'm right about what's going on then that 230 GB folder is going to be showing that pie chart icon for a LOOOONG time. So WTF is going on? If 'Always keep on this device' hasn't actually downloaded the full-fat versions of my files then what the heck was OneDrive doing all through the night and the whole of today? Pretending to download it just to mess with me? Do I actually have to download it twice? Can somebody either explain how and why this is the way that OneDrive is supposed to work (I can't believe that it is), or tell me what I'm doing wrong, or suggest a solution? Or even just confirm to me that I've not gone crazy?OneDrive Files On-Demand Didn't Start
Recently moved from an Intel iMac to a M2 Mac mini running Sonoma. Trying to use Onedrive on an external drive with the above error message keep coming up. Initially it work ok for a few days but then this error occurred. Now I cannot get it to go pass this page and only gives me an option to close. Tried everything without successBuilt an Android app for OneDrive duplicate detection (something I wish Microsoft offered natively)
After years of dealing with duplicate photos and videos in OneDrive, I built a solution and wanted to share it with the community. **The problem:** - Samsung Gallery sync creates duplicates in both "Camera Roll" and "Samsung Gallery" folders - WhatsApp media gets backed up twice (original + shared copy) - App resets/reinstalls trigger re-uploads with "(1)" suffixes - No native duplicate detection in OneDrive **What I built:** OneDrive MediaOps - an Android app that scans for duplicates directly in the cloud. No need to download files to a desktop first. Key features: - Cloud-based scanning (no downloads required) - Algorithm visually identical photos even with different filenames - Preview before deleting - Batch deletion **Why cloud-based matters:** With 50GB+ of photos, downloading everything to run a desktop duplicate finder wasn't practical. This scans media directly via the Graph API. Available on Google Play: https://play.google.com/store/apps/details?id=com.onedrive.mediaops&pcampaignid=web_share Would love feedback from the community - especially if you've been dealing with the Samsung/OneDrive sync duplicate issue.
