Troubleshoot Mnemosyne.
Can't find an item, a document won't import, an assignment isn't showing up, or your license won't activate? Here are the key steps to check before contacting support.
First, identify the type of problem.
If you're having a problem with your files or with some information, start by using the global search and the inspector.
If you're having a configuration issue, check the Settings. If the problem involves a license, first determine which version you're using: Mac App Store or a direct purchase through Lemon Squeezy.
Identify your situation.
I can't find an item
Use the global search, then check the context of the result in the inspector.

I can't find an item
Use the global search with the customer's name, the subject you're looking for, or a keyword from the document.
Next, open the result and use the inspector to check its context and relationships.
I can't import a document
Verify that a customer record exists so that you can link the document to the correct customer file.
Also make sure that a document category is available before resuming the import.
A mission does not appear
A job is linked to a client file. So first, make sure the correct client record is selected.
Next, review the tasks in the client file or use the inspector to verify the relationships.

The financial module is optional.
If you want to use it but it doesn't appear, open Settings and make sure it's turned on.
The screen doesn't seem to make sense
Close and then reopen Mnémosyne.

Understanding your Mnémosyne license.
How it works depends on the purchase channel. The Mac App Store edition does not require a license key. The edition purchased directly from KharonBridge via Lemon Squeezy uses an activation license.
A direct purchase provides a Mnémosyne license.
This license can be activated on two Macs.
A Mac can be deactivated in order to free up its activation for another computer.
No password required
If you purchased Mnémosyne from the Mac App Store, the app is ready to use right after installation. You don't need to enter a license key in the app.
Purchases and downloads are managed through your Apple account.
1 license · 2 Macs
If you purchased Mnémosyne directly from KharonBridge, your license key allows you to activate the application on two Macs.
Activations are managed directly from Mnémosyne under Settings → License and Activation.
Everything is done from Settings.
In the Mnémosyne direct editor, open Settings, then «License and Activation.».
This section displays the license status and the instance of the Mac currently in use. It allows you to activate or deactivate this computer.
So you don't need to contact support just because you're replacing a Mac as part of normal use: you can release the activation yourself before activating the new machine.
Transfer an activation to a new Mac.
If you replace one of your Macs, you can release its activation directly from Mnémosyne and then use the same license on your new machine.
Go to Settings → License and Activation.
The activation used by this computer has been released and can be used on another Mac.
Be sure to use the edition that corresponds to your direct purchase of KharonBridge through Lemon Squeezy.
Enter the same license key in Settings → License and Activation, confirm it, and then activate the new Mac.
If your license is currently being used on only one Mac, you can activate a second Mac directly. Deactivation becomes necessary when you want to replace a machine but both available activations are already in use.
The files on this computer remain readable, but changes are blocked until Mnémosyne is reactivated on this Mac.
Activation Doesn't work?
I can't find my key
Search for the email and information associated with your Lemon Squeezy order.
If you can no longer find this information, please contact KharonBridge using the email address you provided at the time of purchase. Please include your name and the approximate date of the order.
My key isn't accepted
First, make sure you are using the direct download version of Mnémosyne and not the Mac App Store version.
Copy the key associated with your order again, then open Settings → License and Activation to validate it.
I already have two activated Macs
A Mnémosyne direct license allows you to use the application on two Macs.
If you want to use the license on a third computer to replace an older Mac, open Mnémosyne on the Mac you no longer want to use and click «Deactivate this Mac.».
I got a new Mac
You don't need to purchase a new license. Your purchase already allows for activation on two Macs, and each activation can be released from within the app.
If your old machine is still accessible, shut it down before installing and activating Mnémosyne on the new one.
I no longer have access to my old Mac
If you can no longer open Mnémosyne on the old computer to deactivate it and both of your slots are already in use, contact KharonBridge support.
Please use the email address associated with your purchase so that your order can be identified.
I bought it from the Mac App Store
The Mac App Store version does not require a license key.
If you see a key activation process even though your purchase was made through Apple, make sure you’re using the version downloaded from the Mac App Store.
To locate an order, KharonBridge may need your email address used for the purchase, your name, and the approximate date of the transaction. Never send your full credit card number, security code, or Apple login credentials.
Check more carefully Mnemosyne.
You have completed The checks?
If the suggested solutions do not resolve the problem, contact KharonBridge support.
If you're having trouble with a direct license, please provide the address you used during the purchase and specify whether the issue involves activation, deactivation, or switching to a different Mac.
