My macOS vdisk.img is still being reported as 100GiB in the domains folder though Great, sata0-0-2 worked! i enabled the XML edit, enabled trim and below is what system report shows. In both cases, if you have issues attach diagnostics. Probably your alias is sata0-0-2, unraid gui masks it, I don't know why, so add this before Īnd make sure you have discard='unmap' in your disk block.

If trim support is "No", run a terminal in mac os and type Support type should be solid state drive. Select the controller and you will see "support type" and "TRIM support":
After it restarts, to verify trim support is now enabled, go back to About This Mac>System Report>SATA/SATA EXPRESS.īoot mac os, go to About this mac -> System report. The OS will then sit for a short bit, after which time it will reboot itself. It will then give you some text that makes it seem like your computer will eat itself. To fix this, you must force trim on all drives. Recognized as an SSD but no trim support. If you did this correctly, the vm will boot normally. If you only have one, then you can leave it as is, assuming you didn't change the address. If you have any other drives, add an additional copy of the argument (both lines) and modify the "." accordingly to match your address type listed at the top with the disk image(s). I do not know if order matters, but mine is at the end of the arguments list.
Next scroll to the bottom of the xml and add the following in the QEMU argumentsĪny other arguments you have will also still need to be included. Make this change for any disk images you have that the vm uses. (note: it may be possible to leave cache on write back and not use the io native setting, but I didn't experiment much, just followed working directions on the link) With the changes only happening on the second line. With the VM shutdown, edit xml settings, changing the disk image info from (if you're worried about potential loss of data, borking a working vm, or other world ending scenarios, make a backup before doing this, and proceed at your own risk.) The result is the OS slows over time and disk images bloat. Issue: QEMU disks in osx are presented to the OS in a manner which interprets them as a rotational disk, as shown under About This Mac>System Report>SATA/SATA EXPRESS.Įven after forcing trim on all disks via terminal, trim does not work, or even show it as an option. Had a few more minutes today and found it on the Internet ( )

I see a second occurrence of a very similar pattern a bit further in the file: "APPLE SSD TS".I've been looking off and on about how to enable trim support on a disk image in osx.

Run these commands in succession to clear the system caches to enable OS X to pick up the modified driver: sudo kextcache -system-prelinked-kernelĮxactly where am I supposed to see the trim enabled indicator on OS X 10.9.5?

Modify the driver (choose only one of the following lines, based on the version): # 10.9.4 & 10.9.5 YMMV.īackup the original driver: sudo cp /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage-backup
