I'm using the same Noctua NH-D15S that I'd been using since my first hackintosh build from around 2016 and it continues to perform well. Really, any CPU compatible with the motherboard will work. Both work as expected and have no issues with macOS. I am using an i9-9900K but I've also had an i5-9400F on this motherboard. Also, SATA0 is disabled if an NVMe SSD is installed in the M2P connector. So, if you want Wi-Fi/Bluetooth in macOS, you will have to go with a PCI-e solution. The other negative about this motherboard is that Gigabyte decided to block the CNVi port from working with anything but Intel CNVi Wi-Fi/Bluetooth cards.

My much cheaper Oloy DDR4 3200MHz RAM runs at 3600MHz more reliably on this motherboard than my far more expensive G.Skill DDR4 3400MHz RAM. When shopping for RAM, I highly suggest consulting the QVL and also looking around the forums to see which RAM work reliably for other Gigabyte Z390 users. This motherboard is quite finicky with RAM. Please note that my i9-9900K was delidded. I was afraid my cooling solution may not be sufficient for the amount of voltage I anticipate it would require to stay stable. I booted in to 5.2GHz but didn't stay on it for long. I am able to clock to 5GHz with considerably less voltage (1.290v, Turbo LLC) and can even run 5.1GHz reliably at somewhat reasonable voltages (1.320v, Turbo LLC). My theories of better overclocking ability on this motherboard were confirmed. I always like the mATX form factor and have always felt that 3-4 PCI-e slots are enough for my needs. On paper, it appeared to offer everything I would want in a motherboard. While I was able to overclock my i9-9900K fine on my old Z370 motherboard, I wanted to see what the 10+2 phase VRM of this motherboard can do and the option to go to 128GB RAM if/when I ever needed to is cool. I chose this motherboard primarily for the VRM. I will be making lots of references and comparisons with another motherboard that I own, the Asus Z370-G Gaming (Wi-Fi AC) which I feel intimately familiar with. Although I never personally tested any other Thunderbolt devices, I have no reason to believe Thunderbolt devices that work on other hackintoshes won't work here. My EFI will include the SSDT to enable the GC-Titan Ridge. However, I pulled the GC-Titan Ridge card and stuck in my Syba AQC107 10GBase-T card instead to clean up some cable mess in the case and to keep things a little neater on my desk. I do have a GC-Titan Ridge Thunderbolt 3 PCI-e card and it worked fine with the only Thunderbolt device I own, an OWC 10GbE Thunderbolt 3 adaptor.
UEFITOOL GIGABYTE HOW TO
It wasn't until the awesome guys at Acidanthera figured out how to get NVRAM working and Gigabyte finally releasing a reliable BIOS (F9g) that I am comfortable in recommending this motherboard. I've had this motherboard for approximately 9 months now and did not do a build thread for it until now because I struggled so much with getting it to run at a level that met my personal standards for reliability and stability.
