LOGIC PRO X ISSUES AFTER HIGH SIERRA INSTALL

Hi Guys

I recently upgraded my iMac 5k (late 2015) to High Sierra from Sierra. Before the upgrade, my Mac and Logic were running smoothly without any lag or issues. Since the upgrade I have been experiencing issues in Logic Pro X such as System Overload errors, lag when analyzing the EQ spectrum within EQ and higher CPU usage.

I started a project on Sierra, then continued working on it after the upgrade to High Sierra.

I always save current projects to the desktop for better performance on the SSD.

Before I upgraded to High Sierra, I made sure I checked for any updates for my apps and software, performed a clean in CleanMYMac and emptied any trash.

I then created a bootable USB drive from the high sierra installation file. I performed a clean install by formatting my SSD and installing a fresh copy.

I spoke to Apple Support about the issue and they suggested that I perform a reset of the System Management Controller and the NVRAM, which I done.

This made no difference to the performance.

Has anyone else experienced similar issues this or can provide me with a solution to my problem?

Any help would be greatly appreciated.
