A must read for anyone using an APFS format boot Hard Disk Drive.ĭisk Benchmarks with NVMe SSD Upgrade vs SATA III SSDīill sent Disk Benchmark scores of an NVMe Samsung 970 PRO 500GB SSD Upgrade vs previous Crucial M500 SSD in his mini-ITX Hackintosh. Hibernate was originally designed as a safety feature for Laptops on battery power.)Īnalysis of APFS Performance on Rotational Hard DrivesĪ Carbon Copy Cloner article with a detailed analysis of APFS enumeration performance on rotational hard drives (vs SSDs) that explains the much slower performance of APFS formatted HDDs vs SSDs, and how that performance degrades quickly. (There's a post/note below from 2013 on "Why Mac Powers Off after Hours of Sleep - Hibernates/Turns Off", where even later desktop Mac models go into Hibernate after hours of sleep. (Some Macs after sleeping for 3 hours or more go into Hibernate mode, where the macOS system state is written to the drive.) The workaround noted is to enter this command in the Terminal App: Linked OWC support article has a workaround for Kernel Panics seen when waking from deep sleep "Standby Mode". Reports on some Macs with NVMe SSDs Crash on Wake from Sleep/Standby Mode in macOS Catalina.

The teams also found other cards, which, when installed, result in a kernel panic. If OWC Accelsior 4M2 is in any other slot, or if it is configured to use pool A, no kernel panics occur. More importantly, we figured out that the problem only occurs when the OWC Accelsior 4M2 is installed in slots 4 or 5, and only if those slots are configured to use pool B of the PCIe lanes. (See link for OWC info and tip.) "We determined that the kernel panic occurs when the 2019 Mac Pro sleeps.
