Media Bay Glitch

I am having issues with Media Bay ever since version 7.

I am using Cubase 8.5 on a Apple MacBook pro running EL Capitan with a 1TB Lacie Thunderbolt Disk. Whenever I click on a folder media bay is taking too long to scan the contents and show the results, im talking minutes and there may only be 100 samples in the folder. It seems to be a recurring issue which is having an impact on my workflow as I am resorting to using Apple Spotlight to search for samples.

Can anyone shed some light on this please?
