Hello everyone, new member here!
I just had a brand-new iMac (specs in my signature) delivered over the weekend, and I intend for this machine to do most of my producing work. I have been using Logic Pro for some years now on my old MacBook Pro ever since I started taking up producing jobs, so I am fairly familiar with how the entire LPX workflow works.
I had a rude awakening after installing LPX and sorting out my third-party samples (which are housed on my external 1TB thunderbolt-SSD), as Logic seems to have constant beach balls and even hanging after some simple commands, such as playing out my tracks (I am only using at most 2 third-party samples so far), or even as simple as changing I/O buffer size on my Preferences. CPU and RAM usage seemed to be running just fine. My old MacBook Pro, which has inferior specs to my current iMac, performs all of them with generally no problems. In fact, I constantly have projects in my old MacBook Pro carrying in excess of 30-40 tracks with third-party plugins before it starts to overload or even just perform slowly, so this has been very frustrating given the fact that this iMac just came into my possession a few days ago.
Currently my SSD houses the samples for my plugins and my project files, while everything else, including the apps, are in the internal SSD of the chassis. I have prepped as much as possible to make the workflow as smooth as possible. My external SSD is exFAT-formatted though so I don't know if that can be an issue. Could the new LPX and/or macOS versions be the cause of the issues as well?
