2023 Mac Pro M2 Ultra: Sleep/Wakeup Causes Drastic Loss of Performance for both CPU and GPU — FIXED in macOS Ventura 13.5

re: 2023 Mac Pro M2 Ultra: Sleep/Wakeup Causes Drastic Loss of Performance for both CPU and GPU

macOS Ventura appears to have fixed the performance problem discussed in that link.

I say “appears to” because it only takes 1 failure in 100 to prove it wrong. But because it was happening 100% of the time prior to 13.5, it really does look like it is fixed.

macOS Ventura: wildly differing CPU performance, degraded vs rebooted

Below, the same issue afflicts GPU-intensive tasks in Photoshop.

macOS Ventura: degraded Photoshop performance

The world’s most profitable company cannot test properly?

In MPG’s opinion, Apple rushed the Mac Pro out the door with poorly tested software. How can a bug of this magnitude ever see the light of day for end users?!!!

It’s not just this issue, but the guaranteed kernel panic with NVMe blades.

By definition, if an end user can find such severe problems within 24 hours with no special tools or software, the software quality assurance was sloppy, at best.
