CC 2017 makes computer very very very slow

Hi,

After installing CC 2017, my iMac is very very very slow. Even the smallest actions like typing an email takes minutes.

Everything I do takes double the time at least. I constantly see the colourfull rotating cursor.....

Are there more people who have the same problem?

And is there a quick solution, because now I'm not able to work on such a slow Mac....

Kind regards,

Jeska
