Anyone who's now gone to 14.6, and 14.6.1 specifically, found performance issues occurring that severely degrade their x86 computers? I updated two otherwise fine iMac's, that are dated, but high end configs for the time (3.6ghz 8-core 64gb) and the past few days have been horrid. Everything gives me the rainbow spinning disc from time to time, and software that I'm used to how it should behave, Adobe Lightroom editing images for example, is dramatically slower than it used to be even if not producing obvious rainbow wheel GUI pauses; things like merging HDR images, exports, etc. Disk performance seems impacted too; VM's I run in Fusion are incredibly sluggish now.
I'm at the point of wanting to back up and fresh install a pre-14.6, which will be a massive time waste, but my computer is wasting my time by the minute now.
