How to update my helix lt with my old Mountain lion OS

[buzzguitar]

Hello everyones, I'm new here .

just bought the LT , I always used real amps and pedals but I have to ammit this thing really really sounds great.

Now ,I need to upgrade the LT but in my studio I have a Mac with the trusty old Mountain lion OS.

I don't like to change it cause my studio is rock solid now, works perfectly with my sound cards and with my daw and all the plugins.

The line 6 updater for the helix lt doesn't work with it.

the edit works fine ,the mac recognize the helix but not the updater

Do you guys know how to do it ??

thanks

cheers from Italy
