The image should be a dmg or iso made directly from the original disc and burned to a fitting DVD-R or DVD+R medium (not DVD+/-RW). You can't boot directly from the image, though. When you create a disk image using Disk Utility, it saves the file as a CDR. The CDR file extension is the Mac OS X version of an ISO file, which uses the same ISO 9660 format. The only difference in these file extensions is the name. Download a macOS installer, such as macOS Mojave or macOS High Sierra. To download macOS Mojave or High Sierra for this purpose, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6.

Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.

These installers contain a.dmg disk image, which you can restore to a USB key the same way as explained in the Ars Technica article above. Basically, you'll need to open Disk Utility, then select your 8 GB USB key, partition it fully with Mac OS Extended (Journaled). Then from the Restore tab, restore your.dmg to the newly created partition: You can now use your USB key like an installation disc.

You can use a USB flash drive, external hard drive, or DVD-R disc, but the USB drive is quicker. If you're using a USB drive, it has to be formatted as 'Mac OS Extended (Journaled)' and set to partition type 'GUID Partition Table' in order to work.

[Editor's note: This article is part of our. We also have a.] Unlike previous versions of Mac OS X, Lion (OS X 10.7) doesn’t ship on a bootable disc—it’s available only as an installer app downloadable from the Mac App Store, and that installer doesn’t require a bootable installation disc. Indeed, this lack of physical media is perhaps the biggest complaint about Lion’s App Store-only distribution, as there are a good number of reasons you might want a bootable Lion installer, whether it be a DVD, a thumb drive, or an external hard drive. For example, if you want to on multiple Macs, a bootable installer drive can be more convenient than downloading or copying the entire Lion installer to each computer. Also, if your Mac is experiencing problems, a bootable installer drive makes a handy emergency disk.

From here you can either burn the disk image to DVD, or restore it to a hard drive or flash drive. To do this, ensure your medium has at least 4GB of capacity and then follow these steps: Using Disk Utility you can either restore the image to a healthy disk partition (steps 1, 2, and 3), or you can burn it to DVD (step 4) to have it on an optical disc (click for larger view).

I've had Mac OS X Lion installed on a mid-2011 iMac. I've erased the main partition and when I try to repair OS installation it connects to the Internet and says that it can't continue and I should contact Apple Support. I don't have original CD which should've come with an iMac. How can I install at least some version of OS X? Update: I've downloaded what looks like an installation app for Mac OS X Lion with a 4.6Gb InstallESD.dmg file but can't open it on Windows. I've tried PowerISO and MagicISO to no effect.

• In Disk Utility, find this destination drive in the sidebar and then drag it into the Destination field on the right; if the destination drive has multiple partitions, just drag the partition you want to use as your bootable installer volume. Warning: The next step will erase the destination drive or partition, so make sure it doesn’t contain any valuable data. • Click Restore and, if prompted, enter an admin-level username and password. The restore procedure will take anywhere from five to 15 minutes, depending on your Mac and the speed of your drive. Note: In versions of the Lion installer prior to 10.7.4, you didn’t need to first mount the InstallESD.dmg image—you could simply drag the image itself into the Source field.

Diskutil unmountDisk /dev/disk4 • Copy the data to your SD card: sudo dd bs=1m if=image.img of=/dev/rdisk conv=sync where disk is your BSD name e.g. Sudo dd bs=1m if=2018-11-13-raspbian-stretch.img of=/dev/rdisk4 conv=sync • This may result in a dd: invalid number '1m' error if you have GNU coreutils installed. In that case, you need to use a block size of 1M in the bs= section, as follows: sudo dd bs=1M if=image.img of=/dev/rdisk conv=sync This will take a few minutes, depending on the image file size. You can check the progress by sending a SIGINFO signal (press Ctrl+T). • If this command still fails, try using disk instead of rdisk, for example: sudo dd bs=1m if=2018-11-13-raspbian-stretch.img of=/dev/disk4 conv=sync or sudo dd bs=1M if=2018-11-13-raspbian-stretch.img of=/dev/disk4 conv=sync After the dd command finishes, eject the card: sudo diskutil eject /dev/rdisk Alternative method Note: Some users have reported issues with using this method to create SD cards, possibly because earlier versions of these instructions didn't note that it may be necessary to unmount multiple partitions on the SD card. These commands and actions must be performed from an account that has administrator privileges. • From the terminal run df -h.

Most often, a custom background is used and you're presented with an option to drag/copy - and thus install - the application in OSX.

Any computer without a disc drive can read them and use them as a virtual disc.

So if you plan to use that installer on other Macs, or to create a bootable disc or drive as explained here, be sure to copy the installer to another drive—or at least move it out of the Applications folder—before you install. If you don't, you'll have to re-download the entire thing from the Mac App Store. If you've already installed Lion—so it's too late to move the installer—you've may find that the Mac App Store claims that Lion is already installed and prevents you from downloading it again. As I explained in our main Lion-installation article, you should be able to force a re-download using one of the following three tricks: First, Option+click the Buy App button in the Mac App Store. If that doesn't work, switch to the Mac App Store's main page and then Option+click the Purchases button in the toolbar. If that doesn't work, quit the Mac App Store app and then hold down the Option key while launching the Mac App Store again.

If you like, you can rename the drive from its default name of OS X Base System to something more descriptive, such as Yosemite Installer. You can perform the Disk Utility procedure entirely in Terminal. Booting from the installer drive Whichever of the above processes you've used, you can now boot any Yosemite-compatible Mac from the resulting drive: Just connect the drive to your Mac and either (if your Mac is already booted into OS X) choose the install drive in the Startup Disk pane of System Preferences or (if your Mac is currently shut down) hold down the Option key at startup and choose the install drive when OS X’s Startup Manager appears.

If you only have access to a Windows PC: • You will need the OS X install disk image (see above for various methods on how to obtain one), then use the 15-day free trial of to copy the disk image to your USB drive. Be aware that other Windows tools might not be able to read the Apple-native DMG files. The right-side panel of TransMac allows you to right click your USB drive, the format the disk with the disk image. Point it to your.dmg file and click Open., which offers a 5-day trial, probably does the same, but I haven't been able to verify this yet.
