There is the assertion that the cooling is poor due to high idle temperatures on the northbridge – this is totally by design! Apple likes quiet machines… so they keep the fans low and allow chips to reach temperatures that, while safe, are markedly higher than cheap PC designs. It is amazing that “armchair engineers” think the cMP has poor thermal engineering – it is an extremely well designed unit.

Q: Will an NVMe device cause my Classic Mac Pro to overheat our wear out sooner?Ī: I will break my own rule about answering only coherent, intelligent questions.
Q: Who/what is MinnowStor? What do they make and why did they create this?Ī: MinnowStor is a startup that has not come out of “Stealth mode”. This utility lets you define multiple namespaces on your NVMe device, as well as letting you query log pages and SMART data.

Look under the PCI devices and you will see your NVMe device and it will indicate that the driver has been installed.Ī: This is a command line utility to issue NVMe management commands – if you don’t know what that means you can safely ignore this utility. Q: Why does my system report still say: “This computer doesn't contain any NVMExpress devices”?Ī: Because system report uses Apple’s non-compliant NVMe kext infrastructure.

Could there be bugs in the software that cause data loss or crashes? Absolutely – but I have not encountered them. Also, OS X caches heavily and does not provide a true DIRECT_IO equivalent the combination of these factors makes many OS X benchmarks very bad at characterizing device performance – particularly so with small I/O and very fast devices.Ī: Define safe… NVMe devices are just PCIe cards, and are fully electrically compatible with any system with PCIe slots. In particular OS X does not support MSI-X and forces CPU0 to handle all interrupts – although the workloop can distribute some of the load. It depends on your configuration and usage.Ī: Device characteristics, hardware configuration, operating system design, and driver architecture. If you unplug a ThunderBolt connected NVMe device crashes may occur. Q: Does this driver support hot-plug for ThunderBolt configurations?Ī: yes, however it does not support hot “un-plug”. Q: Can I use this to support an NVMe device in an external ThunderBolt enclosure like the Akitio? Why they use the NVMe name for a non-compliant device and driver is a mystery. Q: Doesn’t Apple supply NVMe drivers and EFI boot ROMs for their new machines?Ī: Apple chose to make their NVMe devices and drivers non-compliant with the NVMe standard.
Q: What devices have you tested this with?Ī: Intel P3700 series, Samsung SM1715 and SM951 seriesĪ: No, not until someone writes a standards compliant EFI driver for the Macintosh. Q: What version of OS X does this driver support?Ī: /Library/Extensions – Note that the owner and group for the entire kext MUST be set to root:wheel Just downloaded and tested the brilliant new driver for NVME m.2 x 4 PCIe from Checkit it out!
