Hi there! Sorry to confront you with some big red text like this but you should know that on June 1st 2023, we discontinued support for older versions of the Mac app.
This means that you will need to install the latest version which can be found in the App Store here.
Please know you will require macOS 12.4 or higher in order to install the app.
The size limits for your transfers apply the same as on our web and mobile services.
With a WeTransfer subscription, you can send as many transfers as you'd like with the Mac app.
However, if you have a Basic account and wish to use the WeTransfer Mac app, please know that a maximum of 3 transfers per day can be sent.
Our web and mobile services do not have this limitation, so If you'd like to send more transfers, please visit www.wetransfer.com and send as many transfers as you'd like!
