Engine Prime not seeing my internal hard drive

Hi guys, got an odd one here. I have a Samsung EVO exFat formatted HD in my P4, when transferring crates via EnginePrime on my iMac, all is good, my internal drive comes up within 5 secs. When trying to do the exact same on my Macbook, the internal drive does not appear in EnginePrime. Ive tried everything, updates, firmware, software…the funny thing is that I also have an external SSD connected through the USB port on my P4, and Engine Prime sees that drive when in computermode/standalone and connected to my MacbookPro. Any ideas please? :slight_smile:
