I have many problems since I had installed osx hight Sierra and I don't understand the reason why ...
First I had the security app problem hight Sierra but I fixed it and Logic Pro x start virus ti plugin perfect
But Today I had added all my soundbanks collection ,,, about 100 sound banks and I never had problems to start in Logic Pro x because I inserted the virus ti plugin and it was opened 5 seconds after I insert it .... my surprise is that it takes longer to open depending on the number of banks that i want copy in document / virus ti / patches
it is crazy ... I have timed the time:
virus ti plugin opens after 5 seconds of inserting it if I have not any soundbank copy in the folder
virus ti plugin opens after 1 min of inserting it if I copy a part of my sound banks in the directory
virus ti plugin opens after 5 min of inserting it if I copy all my collection sound banks
