UR44 w/Macbook Pro 2017 (Pro Tools)

hey guys, im having issues with digital clicks when recording audio and was wondering if anyone could help me out.

ive got the latest version of pro tools running on a macbook pro 2017 model, with the ur44 as my interface. does anyone have any experience using these with the new USB-C ports/adapters? ive got mine plugged into an apple USB to USB-C adapater and i think this is causing me issues.

ive done all the recommended optimisations and increased my buffer size but still get at least one click on every track i record. they occur at different times and always differ in volume.

any help would be greatly appreciated!
