Thanks for your report, Andre. This is likely due to Catalyst scaling the UI down 77% of its normal size in combination with a non-retina screen. We're planning to compensate for the scaled UI elements in a future update which should improve how it looks and reduce blurriness.

ver. 4.16.0 (8741) : noticed am improvement but still far away from readabilty of TDA Mac OS with my hw at least even in full screen

We haven't touched this topic just yet. Where did you notice an improvement?

in this latest release only if going in FULL screen

Alright, thanks for letting me know. You'll read it in the release notes when we start making changes that should improve readability.

Awesome, no complain, really good job!

BTW checked with the Smartbike and there are a few bugs with italian traslation on the bike setting/options

That's great to hear. Thanks!

I think the translations are a known issue and should be resolved as soon as possible.
