For this reason, older versions of Windows (like Windows 98) can run better than more modern versions like Windows 7 or 10. It’s also quite draining in terms of processing power and available memory to run two operating systems at once, as you’ll need to provide the VM with a portion of your available power. There have been big leaps forward in terms of virtualized 3D graphics performance over the past few years, but you may still encounter compatibility problems like glitches, poor performance and some games refusing to run. Virtualization does come with a few drawbacks, however. Using specially designed software you can scale your “virtual machines” based on your requirements. You’re essentially emulating the hardware and running Windows on top of it. What better way to run classic Windows than using a native environment? Virtualization allows you to install and run Windows on your Mac, inide macOS. This is best for: Windows 95, 98 and XP titles or games that use software or hardware rendering. Once Terminal is open, input the following command but replace home/username/disk.cdr with the path to the file you created with Disk Utility, and home/username/disk.iso with the destination path and name for the ISO file you want to create: hdiutil convert /home/username/disk.cdr -format UDTO -o /home/username/disk.iso.You’ll find Terminal in Applications > Utilities, or just search for it using Spotlight (or a Spotlight alternative). You can convert a CDR file to ISO using a quick Terminal command. The file needs to be in ISO format though to use most of the methods to play it below.

You’ll be left with a CDR file that will mount on your Mac like a hard drive or DMG file.Click Save, disabled, and begin the process. Make sure you select 'DVD/CD master' in the Format dropdown, and ensure Encryption is set to none. Name your file and select where you want to save it.Head to File > New Image > Image From 'Device' and choose your optical drive.Insert your CD or DVD into your optical drive, and launch Disk Utility.If you do have a SuperDrive, or you’re using a Mac that is blessed (cursed?) with an optical drive, here’s how to extract a disk image and convert it to an ISO disk image file: For quickness, you might want to just use disk images though, which contain all the data found on a CD or DVD as a file stored on your computer. But old CDs and DVDs of games can still help you out here.Īpple sells an external optical USB SuperDrive that will allow you to use your original CDs and DVDs to play games. There’s a good chance you’ve moved on from optical media, particularly if you’re using a modern MacBook without a CD/DVD drive.

Before you can play old games on your Mac, you need to get them on there first.
