Using these sources, this dissertation assesses 1) the impact grain agriculture had on enslaved people and the economic impact of enslaved farmers, 2) the food rations issued to enslaved Shenandoahans and the ways they grew, gathered, raised, and hunted at night and on Sundays to ensure their families had enough to eat, 3) how restrictions on enslaved people’s consumption practices limited their ability to travel to, and buy goods from, cities, towns, and country stores, 4) the ways enslaved people used imported tea and tablewares and locally-made utilitarian ceramics to make lives for themselves, and the larger economic implications of these actions, and 5) the struggles between enslaved Shenandoahans and their enslavers that took place through local landscapes. Data for this project comes from archaeological excavations at the main enslaved quartering site at Belle Grove Plantation and 19th-century written sources from Frederick and Shenandoah Counties, Virginia, and Jefferson County, West Virginia. Specifically, this project answers two questions: what was life like for enslaved people in the Shenandoah Valley, and how did they shape the region's political economies. Scholars did not widely acknowledge the presence of slavery in the Valley before the 1990s, and this is the first work to provide an in-depth view of the lives of enslaved Shenandoahans before 1860. For example, if at step 3 your downloaded disk image mounted as AHTCThree, then at Step 5 you would use AHTCThree instead of AHTCOne within the Terminal command.This dissertation is a study of the lives of some of the people enslaved on rural plantations and farmsteads in the northern Shenandoah Valley region of Virginia. However, assuming you have downloaded the AHT version for your Mac, then this answer can be adapted for your use by replacing the AHTCOne with whatever name your downloaded disk image mounted as at Step 3.Likewise, the Terminal commands used in this answer are for this specific question.Note: Macs introduced after June 2013 use Apple Diagnostics instead. So this answer will not apply to you unless your Mac also requires AHT 3A238. Different Macs require different versions of Apple's diagnostic software.Now test to see if your Mac can run Apple Hardware Test or not. Select the AHT option from the list and boot up Leave the USB flash drive plugged in and restart your Mac Sudo bless -folder /Volumes/AHT/ -file /Volumes/AHT/System/Library/CoreServices/.diagnostics/diags.efi -label AHT Now we need to make the USB flash drive bootable, so enter the following line in Terminal: In the Terminal window, enter the following:Ĭp -r /Volumes/AHTCOne/System /Volumes/AHT/ To start, Launch the Terminal app (usually found within the Utilities folder) Now you will need to copy the AHT to your USB flash drive.Mount the downloaded image (it should mount as AHTCOne).Now download the AHT for your particular Mac (i.e. For the purposes of these steps, also give your USB the name AHT when you're erasing it. Make sure you choose OS X Extended for the format and the GUID Partition Map for the scheme. Create a bootable USB flash drive by using Disk Utility's Erase function.Let's see if we can get Apple Hardware Test working from a bootable USB drive. I was able to capture the screen by taking a video of the process and then selecting the still frame. I did the same thing on another machine - an Air, and it loaded the AHT, but said "Machine not supported", when I tried to run it, (which makes sense since the AHT is for a different model). I select EFI Boot, and a very quick black screen with a bunch of text appears and then the apple logo and loading bar appears. On holding option at startup, I'm presented with a screen with three options: Macintosh HD, Windows, and EFI Boot. I created a bootable USB with the relevant AHT as per the answer below. How do I get apple diagnostics running again? The same errors as above occured with option+D on startup as well. After I copied the files, I restarted with D pressed, but I was met with the same errors. To copy these files to the correct location I turned off SIP by going into recovery mode. There was no folder at /System/Library/CoreServices/ called. I researched online and a suggestion was that somehow the diagnostics tool is missing. I select the appropriate network and then it errors saying: On pressing R, the error continues further saying: I tried restarting with the D key pressed, with the intention of running Apple Hardware Test. For a related question, I was trying to run apple Hardware Test (Apple diagnostics) on my Macbook Pro Retina.
