## Disks and Volumes
2015-09-22 17:23:45 -04:00
2015-09-24 12:11:34 -04:00
#### Disable Sudden Motion Sensor
Leaving this turned on is useless when you're using SSDs.
```bash
sudo pmset -a sms 0
```
#### Eject All Mountable Volumes
The only reliable way to do this is by sending an AppleScript command to Finder.
```bash
osascript -e 'tell application "Finder" to eject (every disk whose ejectable is true)'
```
#### Repair File Permissions
You don't have to use the Disk Utility GUI for this.
2015-10-13 14:02:56 -04:00
```bash
sudo diskutil repairPermissions /
2015-10-13 14:02:56 -04:00
```
> Beginning with OS X El Capitan, system file permissions are automatically protected. It's no longer necessary to verify or repair permissions with Disk Utility. ([Source](https://support.apple.com/en-us/HT201560))
2015-10-13 14:02:56 -04:00
#### Set Boot Volume
2015-09-25 10:40:55 -04:00
```bash
bless --mount "/path/to/mounted/volume" --setBoot
2015-09-25 10:40:55 -04:00
```
#### Show All Attached Disks and Partitions
2015-09-25 10:43:15 -04:00
```bash
diskutil list
2015-09-25 10:43:15 -04:00
```

```bash
sudo fs_usage
```
### Disk Images
2015-11-05 14:26:08 -05:00
#### Create Disk Image From Folder Contents
```bash
hdiutil create -volname "Volume Name" -srcfolder /path/to/folder -ov diskimage.dmg
```
If you'd like to encrypt the disk image:
```bash
hdiutil create -encryption -stdinpass -volname "Volume Name" -srcfolder /path/to/folder -ov encrypted.dmg
```
By default, you'll be prompted for a password. You can automate that by piping in a password:
```bash
echo -n YourPassword | hdiutil create -encryption -stdinpass -volname "Volume Name" -srcfolder /path/to/folder -ov encrypted.dmg
```
2015-11-02 01:16:55 -05:00
#### Burn Disk Images to DVD
This command applies to .iso, .img and .dmg images.
```bash
hdiutil burn /path/to/image_file
```
#### Disable Disk Image Verification
2015-09-22 17:23:45 -04:00
```bash
defaults write com.apple.frameworks.diskimages skip-verify -bool true && \
defaults write com.apple.frameworks.diskimages skip-verify-locked -bool true && \
defaults write com.apple.frameworks.diskimages skip-verify-remote -bool true
2015-09-22 17:23:45 -04:00
```
#### Make Volume OS X Bootable
2015-10-13 14:02:56 -04:00
```bash
bless --folder "/path/to/mounted/volume/System/Library/CoreServices" --bootinfo --bootefi
2015-10-13 14:02:56 -04:00
```
#### Mount Disk Image
2015-09-25 10:38:10 -04:00
```bash
hdiutil attach /path/to/diskimage.dmg
```
#### Unmount Disk Image
```bash
hdiutil detach /dev/disk2s1
2015-09-25 10:38:10 -04:00
```
2015-10-19 19:16:31 -04:00
#### Write Disk Image to Volume
Like the Disk Utility "Restore" function.
```bash
sudo asr -restore -noverify -source /path/to/diskimage.dmg -target /Volumes/VolumeToRestoreTo
```

#### Set Software Update Server
This should only be done for testing purposes or unmanaged clients. To use network-wide, either correctly set up DNS along with [Apple SUS service](http://krypted.com/mac-security/using-the-software-update-service-on-mountain-lion-server/) and bind your clients via OpenDirectory. Alternatively, use [Reposado](https://github.com/wdas/reposado) together with correct network DNS settings to make resolution transparent. [Margarita](https://github.com/jessepeterson/margarita) looks nice to have as well.
```bash
2015-12-03 17:56:06 -05:00
# Use own SUS
sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate CatalogURL http://su.example.com:8088/index.sucatalog
