Check if you can see the external hard drive in Disk Utility again. Select an ISO file or a distribution to download, select a target drive (USB Drive or Hard Disk), then reboot once done. Move your mouse and put it on the 'External' option. I got an Asrock B560m Pro 4 and now my SATA drives are showing, so I believe the problem was with the SATA controller on the h61. Open Disk Utility after you connect the external hard drive to your Mac. Restart your Mac and press Command + R and keep them both pressed until you see the Utility menu (Recovery Menu) appearing. But that drive died.ĮDIT: So sadly this motherboard died (my fault) but this allowed me to build a new pc as this one was very old. Catalog files contain the record files of partitioned volumes. The file system is responsible for how data is organized and stored in a drive. What's annoying me is that I made a hackintosh last year (High Sierra, as I had a nvidia 10xx card) and I encountered the same problem with my drives not showing, but I somehow fixed it (Don't remember how :( ). Why does Macintosh HD not mounted/showing in Disk Utility 1. Here are the steps For reference Im running Mac OS Monterey (v12.0.1). I am also using HfsPlus.efi and do not have any kexts related to intel wifi or bluetooth. The easiest thing to do is just to reformat your drive to ExFat using Disk Utility. The Drive is GPT and I have enabled AHCI in the BIOS.

I am trying to install MacOS Monterey using OpenCore (following the Dortania Guide) but when I open disk utility in the installer it is neither showing my SATA SSD nor my SATA HDD and is only showing my USB drive.
