Mac does not support trados now, unless it is equipped with a dual system, but it will also cause fever, which is not particularly recommended.
So I suggest choosing online CAT tools, such as YiCAT and smartcat I just mentioned.
It will save time if you bring tens of millions of corpora when you link to the YiCAT web page. Smartcat is a foreign country, so I personally feel that the loading will be a bit slow.
The landlord can experience it himself before choosing.
