Mac mini 2012 slow after Sonoma fresh install

Hello,

I have a 2012 i7 Mac mini 16GB, 500GB SSD, 1TB HDD for data/backup.

Up until yesterday, I was running MacOS Ventura where performance was super snappy.

Yesterday, I performed a clean install of Sonoma, once complete, I then ran the root patches and rebooted. The OS appears to be rather sluggish, apps and windows are very slow to open, whereas before things opened instantly.

I used the latest version of OCLP (1.5.0) where I was installing MacOS 14.5

Would be interested to know whether anyone else have seen such issues?

Thanks!
