|Version|Date|Notes|
|---|---|---|
| |2021-03-17|Add RAM=max and RAM=half to dynamically select ram at runtime (DEFAULT).|
| |2021-03-06|Change envs to require --envs. Automatically enable --envs if --output-env is used. Same for plists, bootdisks. Fix help ugliness and sanity of generate serial scripts. Fix bootdisk not getting written to persistent file when using NOPICKER=true. NOPICKER=true is overridden by a custom plist now anyway. Remove useless case statements. Allow -e HEADLESS=true as human readable alternative to -e DISPLAY=:99.|
|4.1|2021-03-04|Add `-e MASTER_PLIST_URL` to all images to allow using your own remote plist.|
| |2021-03-03|Add `WIDTH` and `HEIGHT` to set the x and y resolutions, use in conjuction with serial numbers.|

This is my favourite container. You can supply an existing disk image as a docker command line argument.
Pull images out using `sudo find /var/lib/docker -size +10G | grep mac_hdd_ng.img`
Supply your own local image with `-v "${PWD}/mac_hdd_ng.img:/image"` and use `sickcodes/docker-osx:naked`
- Naked image is for booting any existing .img file.
- Naked image is for booting any existing .img file, e.g in the current working directory (`$PWD`)
- By default, this image has a variable called `NOPICKER` which is `"true"`. This skips the disk selection menu. Use `-e NOPICKER=false` or any other string than the word `true` to enter the boot menu. This lets you use other disks instead of skipping the boot menu, e.g. recovery disk or disk utility.
