Compare the Two Objects Before Reinstalling
If Ledger Live opens from Downloads but not Applications on your Mac, confirm that you are launching the same release and kind of object. One may be an installed application while the other is a disk image, an app inside a mounted volume or an alias. The product’s current name is Ledger Wallet.
The difference in location is useful evidence, but it does not by itself identify the cause. An incomplete copy, stale shortcut, incompatible version or security refusal can produce different outcomes that need different responses.
Inspect Each Location in Finder
Find the object you open successfully and the one that fails. Use Finder’s Get Info and location information to record their names, versions where shown and kind. If one is an alias, identify its target. If one belongs to a mounted disk image, distinguish that volume from your Mac’s Applications folder.
Do not compare icons alone. A file ending in DMG is an image containing installation material, not proof that the app has already been copied to the intended destination. Two visually identical app icons can also represent different releases.
Record the Applications Launch Result
A Security Warning Appears
Preserve the entire message. A harmful-software finding, damage warning and unidentified-developer message are different assessments. Apple’s Mac app security guidance explains those distinctions. Do not remove quarantine attributes or turn off Gatekeeper just because another copy launches.
Another Copy Opens Instead
Quit the existing instance normally when no hardware update is progressing, then launch the intended Applications item directly. A running copy can make a click on another icon seem inconclusive. Check the actual version and path before deciding the second app cannot open.
Nothing Visible Happens
Look for an existing process or hidden window before repeating the installation. A client running without a visible window is a different symptom from macOS rejecting the application bundle before launch.
Complete One Supported Copy Procedure
Obtain the appropriate package through the official Ledger download page. Follow its installation instructions rather than copying a desktop alias or a partially downloaded file. Apple’s internet app installation guide describes the general Mac workflow.
If replacement prompts appear, read which existing item will be replaced and why. Use the permissions expected for your account and destination. An organization-managed Applications folder may require administrator help; changing broad folder permissions is not a substitute for understanding that restriction.
Once copying finishes, quit any app still running from the image during an ordinary idle session. Open the Applications copy directly and confirm the intended version. Only then repair its Dock or other shortcut so future launches use the same destination.
A Practical Example
Suppose a recent app runs inside a mounted download image, but an older Applications copy immediately fails. Comparing versions reveals that the apparently successful installation never replaced the old bundle. Completing the documented copy process addresses a different problem from a case where both identical copies trigger the same security warning.
Keep local application data separate from bundle replacement. Account names and preferences can live outside the app itself. Avoid a broad profile purge when the evidence concerns only which program was copied and launched.
Downloads Versus Applications FAQ
Should I keep using the copy in the disk image?
Follow the publisher’s installation route and use the intended installed destination. A temporary download location can make updating, ejecting and maintaining shortcuts unnecessarily confusing.
Does moving the app require a new wallet?
Application location does not define the hardware wallet’s keys. Do not initialize the Ledger again or provide a recovery phrase to a computer prompt to repair a copy operation.
What should I report if the new copy still fails?
Include both locations, the selected release, Mac model, macOS version and exact warning or visible behavior. Those details let support distinguish copying, compatibility and launch-state issues.
