Apple Mac Mini on VMware HCL!

by // 15 Comments

For the past 6 years, the Apple Mac Mini has been one of the most popular hardware platforms for Virtualizing MacOS running on VMware vSphere enabling our customers to develop and build iOS and MacOS applications. With that said, VMware has historically only supported two Apple hardware platforms: Xserve (now EOL'd) and the Mac Pro (6,1) which is officially listed on VMware's Hardware Compatibility list and this has been officially supported by VMware since 2012 when we first introduced support for MacOS Virtualization with the vSphere 5.0 release.

As many of you know, I have been a huge advocate of this platform for a number of years now and I have been working with various Engineers over the years to ensure that we have the exact same user experience when working with ESXi on the Mac Mini as you do with the Mac Pro. I still recall in the early days where it took several "hacks" to get ESXi to successfully boot and install.

Today, ESXi installs on the Mac Mini just like any other x86 platform. It runs amazing well for our customers, especially for a consumer device, who have deployed them in their datacenters ranging from a couple hundred to several thousands for some of our larger Enterprise customers, one such example is MacStadium, the largest Apple Infrastructure-as-a-service provider which many of the Fortune 100/500 companies are leveraging to provide them with a platform to build and develop for the Apple eco-system.

UPDATE (08/27/20) - Apple 2018 Mac Mini 8,1 has been added to VMware HCL which supports both ESXi 6.7 Update 3 (Patch 03) & ESXi 7.0b

Quick Tip - Crucial NVMe SSD not recognized by ESXi 6.7 & 7.0

by // 85 Comments

If you own or have recently purchased Crucial NVMe SSD such as CT1000P1SSD8 (1TB M.2 NVMe SSD) or CT500P1SSD8 (500GB M.2 NVMe SSD), please be aware that these devices may no be recognized by ESXi after upgrading to the latest release. Thanks to Pete Lindley, (OCTO for End-User Computing), who reached out last week regarding the observation as well as a workaround for the problem. This was also quite timely as I recently purchased a Crucial M.2 NVMe SSD and would have also ran into this problem.

It turns out these Crucial devices were working fine while running on ESXi 6.5 Update 2 but was no longer recognized in latest release of ESXi 6.7 Update 2. It is unclear whether support for these SSDs were removed intentionally or unintentionally, but in either case, these devices are not officially on VMware's Hardware Compatibility List (HCL).

UPDATE (07/29/20) - Over the past few months, I have had a number of folks share feedback that using the trick mentioned below for ESXi 7.0, they have had success of ESXi detecting their NVMe SSD. I wanted to share some of the model and/or vendors that folks have reported success with. I will keep this list updated, so feel free to leave a comment below.

UPDATE (06/13/20) - Thanks to reader Dave, it looks like this trick also works with ESXi 7.0 but the filename has changed. Simply copy nvme.v00 VIB from the ESXi 6.5 Update 2 and replace it on ESXi 7.0 system (either live under /bootbank or part of the installer) but rename the file to nvme_pci.v00 which is the new filename for NVMe driver.

UPDATE (05/23/19) - After speaking with a few folks who took a closer look, the issue is due to the fact that we added support for NVMe 1.3 spec in latest ESXi 6.7 Update 2 release, but because these are "consumer" devices, they did not conform to the latest specification and hence the driver is unable to claim the device. This is another good reminder when using components not on VMware HCL, this is always a risk from a home lab perspective. In general, I know Samsung and Intel NVMe SSD usually works quite well without issues but always good to do some research. I think Engineering is looking to see if there are other workarounds for the future, but for now, you can use the workaround below.

The easy workaround that Pete found was to simply replace the NVMe driver from ESXi 6.7 Update 2 (1.2.2.27-1vmw.670.2.48.13006603) with one found in ESXi 6.5 Update 2 (1.2.1.34-1vmw.650.2.50.8294253). To so do, simply copy nvme.v00 to /bootbank from either an existing ESXi 6.5 Update 2 system or directly from the ISO. Please note, any future updates or patches to the ESXi host will most likely override the updated driver.

vSphere 6.7 Update 2 add support back for Apple Mac Pro 6,1

by // Leave a Comment

Last fall, support for vSphere 6.7 Update 1 on the Apple Mac Pro 6,1 was removed by VMware after finding out an updated version of the Apple Firmware prevented ESXi from booting up properly after upgrading. After some investigation and troubleshooting with several customers, VMware Engineering found a solution to workaround the problem and that fix is included in the latest vSphere 6.7 Update 2 release. As mentioned in the original blog post, this could also impact Apple Mac Mini's, which are not officially supported by VMware, but the fix should also apply to the Mac Mini.

In addition, the VMware HCL will also be updated shortly to reflect support for both vSphere 6.7 Update 2 along with the existing vSphere 6.7 support. For customers that have been waiting for features in vSphere 6.7 Update 1, you can finally upgrade to the latest release to get all the new features and benefits of vSphere.
