Mac OS Lion

Mac OS 10.7.5 won't run Teamviewer 11 at all. It allows the install but crashes on start up. Tearing my hair out with this. Trying to control a clients machine and he was originally on version 9. My iMac was originally with version 14 on High Sierra but I've loaded version 12.

Any ideas appreciated. Thanks.

    Hello @rasg01

    Thank you for your message.

    We are sorry to hear that you encounter difficulties with our software.

    As Mac OS X Lion 10.7 is compatible from version 6 to 11, I recommend you to try with another version (6, 7, 8, 9 or 10). You can download them here: Previous TeamViewer versions

    If you own a license, feel free to open a ticket here.

    I hope this could help. If not, do not hesitate to ask your questions here.
