I have an account and password at the website, but on two different Macs I get the “jammr quit unexpectedly” dialog box the moment I click to open the software. (2 different OS versions: 10.10.5 and 10.8.5)

Help! I'd love to use the product!

Hi,
The latest version of jammr is tested on macOS Sierra (10.12). This could explain why it won't run.

Please open Applications | Utilities | Console. More details on how to open the Console application here:
http://apple.stackexchange.com/questions/26480/where-can-i-find-my-crash-logs

In the Console application you can find the jammr crash reports under “User Reports”.

Please copy-paste the crash report onto the forum here. Or you can email it to info@jammr.net.

Thanks,
Stefan

Thanks Stefan, the Crash report is very long, I'll email to info@ as you've suggested.

Thank you!
