Start with these three steps
Disconnect power safely
If liquid entered the case or the iMac was physically damaged, stop using it. Disconnect at the wall when safe; do not touch wet plugs or damaged electrical parts.
Record what happened
Note the time, impact or liquid involved, any unusual sound and every power attempt since. Photograph exterior damage without opening the enclosure.
Protect original components
Keep the iMac, previously removed parts and backup disks available. Ask anyone assessing it to preserve the original storage and logic board until the data decision is made.
A damaged desktop needs a different first response
Apple advises disconnecting an iMac after a spill, case damage or suspected need for repair, and warns against using a cracked display. For a 24-inch iMac, unplugging at the wall fully disconnects power. Do not keep switching it on to see whether it has dried.
Leave enclosure opening to an appropriate technician. A display removal that goes wrong can add damage before the storage has even been assessed. Record the symptoms already observed; recreating the failure is unnecessary when you can explain it clearly.

Describe the event and the data separately
Distinguish a broken screen from an impact followed by storage noise, a spill into ventilation openings or a failure after a power event. These histories help an assessor decide which parts require attention first. A normal-looking display does not establish that the disk is healthy.
Make a priority list such as the family Photos library, current accounts folder and a specific client project. Include the usual external drives. The needed files may be on an intact archive disk even when the iMac itself requires substantial repair.
The generation changes what must be preserved
Older configurations can involve a hard drive, SSD or Fusion Drive. A Fusion arrangement combines two devices, so keep both members after any previous drive replacement. Do not discard the smaller device because it looks like a cache.
Apple specifically warns that catastrophic failure of an iMac Pro’s hardware-encrypted storage can prevent recovery. That makes preserving original components particularly important. Replacing a failed assembly may restore the computer’s usefulness without restoring the files that remained on it.

Make the recovery objective part of the handover
Before agreeing to repair, ask what will happen to the original storage, whether any erase is proposed and how recovered files would be returned. Request a review point before work that would remove the remaining recovery options.
Data Recovery Lab NZ is an external recovery provider whose published scope includes Macs, hard drives and SSDs. Ask it to confirm the route for your exact iMac model and damage. Provide symptoms and credential availability initially; share a password or recovery key only through an agreed private process if required later.
A realistic view of recovery
- Physical repair cannot guarantee readable data or restore encryption material that has been destroyed.
- A successful temporary startup is a chance to copy priority files, not proof that a damaged iMac is reliable again.
Your questions, answered
Can a broken display mean the files are still intact?
Should I remove the drive before sending it?
Can a replacement logic board recover my old files?
