Upgrade to 5.03 and now its skipping and not usable.

I have a super fast new and very capable Macbook pro and I do not have any issues with rekordbox 4 but as soon as I upgraded to 5.03 I now can not use my software because it skips the tracks so bad I can not even keep stuff playing. I am super upset about this since its been plenty of time to have had this fixed. This is not like a just released beta version this is something that I have paid good money for and it has Pioneers name and price attached to it. I went back to try and use my version 4 software and now its doing the same thing which can only mean one thing and that it has something to do with the drivers that it changed when I updated to 5.03. I have been in the dark with this issue for while and would love an answer and fix to this problem so I can get back to my artistic release and on weekends my job. Please fix this with an update. I am using Seirra high 10.13.2 

This really needs to be fixed. Please please make this a priority soon. I do not want to have to buy different software and switch to something else after spending over $500 Thanks
