[[!meta title="NetBSD/evbarm on Apple Silicon"]]
Initial support was added to NetBSD -current for Apple M1 systems on Aug 30, 2021.
Please note that installation on an Apple M1 requires macOS 11.2 or later to be installed first.
- Uncompress <http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/evbarm-aarch64/binary/gzimg/arm64.img.gz> and write it to a USB drive. *Make sure this file was built after Aug 30, 2021!*
- Build and install `sysutils/u-boot-apple-m1` from pkgsrc.
- The bootloader will be installed to `/usr/pkg/share/u-boot/apple-m1/u-boot.macho`.
- Boot the M1 system into 1TR mode by holding the power button at startup. Until the "Loading startup options..." message is displayed, then select Options.
- In the Utilities menu, select Terminal to bring up a root shell.
- Downgrade security and disable SIP. (If you get any errors while doing this, first run `csrutil clear`, reboot, and try again)
- `# bputil -nkcas`
- `# csrutil disable`
- Copy the u-boot.macho from pkgsrc to the mini over the network (curl, sftp, etc).
- Install the new bootloader:
- `# kmutil configure-boot -c u-boot.macho -C -v /Volumes/Macintosh\ HD/`
- Reboot with a USB drive plugged in.
# Supported hardware
