That isn't a problem per-se, in that it would be expected that updated drivers might be needed for some or all hardware devices when upgrading an operating system version. RME are very good at providing driver updates (even for their older products).
Thank you Martin for the very quick respons.
You are right, it is not a strange thing RME UCX needs an update when the OS changes.

One person did report to us that High Sierra needed slightly more memory for itself on his 4 GB Mac (which isn't wholly surprising, since new versions of operating systems tend to be larger than older ones), so he needed to load slightly less data in Hauptwerk otherwise he had performance problems. However, doing so solved his issue.
My MacPro 2010 system has plenty of RAM with 96GB. So that is not an issue I think.

Okay, I understand. I will give it some time and we will see.

Yes, I tried different samplesets. Normally I am playing rather big samplesets like Zwolle or Rotterdam. But this CPU behaviour appears also with smaller sets loaded.
I am currently loading the St. Anne's also to check wether the CPU spike appaers.

I will look into that and let you know.

mdyde wrote:Do you mean that you used the option in the macOS installer to restore your settings/apps/files/etc. from a Time Machine backup? If so, that wouldn't be the same thing as doing a truly clean install. On any new operating system version my advice would always to install it absolutely clean, then install all of the necessary software and drivers (all at their latest versions, checking on their makers' websites) from scratch. That way you don't risk carrying over any old components from your previous operating system installation.
Yesterday I did a clean install of the OS High Sierra itself with a bootable USB stick. Before that I did format the original boot disk (pci ssd).
After the installing of the OS complete, yes, I did a restore of settings/apps and all kind of personal files from a Time Machine Backup.
So I guess there is probably something wrong within these restore?
It would be very time consuming to collect and reinstall al kind of apps I fear.
Dear Martin, thank you so far. I first will look into the behaviour of St. Anne's and also the Mac built in audio output.
