.Not original media. Mac OS X Tiger Install Disc (2005)I don't have a Mac to test this with, but the files appear to be intact. Install Mac OS X 10.4 Tiger on VirtualBox Prerequisites. This guide assumes that you have: a Mac OS X host environment, running VirtualBox on an Intel Mac; a universal or i386 install image or disk for Mac OS X 10.4 Tiger; The environment of the example installation procedure was: MacBook Pro (Retina, 15-inch, Mid 2014) OS X El Capitan (10.11.6).

Mac OS X 10.4 Tiger uses less memory than Leopard, supports Classic Mode on PowerPC Macs, and, unlike Leopard, is supported on G3 Macs, so there are good reasons to install or reinstall it on your old Macs.

Why Tiger Instead of Leopard?

As Apple refines Mac OS X 10.5 Leopard and moves closer to the release of 10.6 Snow Leopard, the 10.4 Tiger version of OS X seems destined to fade into computing history. However there are many compelling and unique features in Tiger that make it an ideal or necessary OS on some Macs.

On PowerPC machines, Tiger is the last version of OS X that supports Classic mode, the built-in virtualizer for Mac OS 9 applications. Using Classic mode on a Power Mac G3 or better, it is still possible to run many applications compiled for the original 680×0-based Macs as far back as the 1980s. Some older software or peripherals will only run under OS 9, and Classic mode extends their lifetime. Often a Tiger-based Mac will be a secondary machine repurposed just for this task.

On Intel-based Macs, there are people who stick with Tiger for several reasons. This may be a budgetary decision, since upgrading to Leopard requires obtaining an installer, possibly some application updates, and often adding more RAM. Leopard’s minimum RAM footprint is about twice what Tiger requires. I recommend 1 GB minimum for Leopard on PowerPC Macs and 2 GB minimum on Intel systems – these are twice Apple’s minimum recommendations.

Also (not infrequently), some people just dislike the newer OS in favor of the older version.

On an original Intel-based Mac with a 2 GB RAM limit or a PowerPC G4-based Mac with a limit below 2 GB, the system will perform better under Tiger than with Leopard if you’re running RAM-hungry apps like Final Cut Pro or the Adobe CS suite, because 10.4 leaves more RAM available to applications.

Obtaining an Installer

Download Mac Tiger Install Disc Player

The ability to install, reinstall, or upgrade to Tiger remains important, but it is increasingly difficult. Mac OS X 10.4 install discs have been discontinued by Apple and are no longer sold at retail. Finding an installer requires buying a new or used copy from a reseller – or borrowing a copy from a friend, consultant, or other Mac user.*

To increase the challenge, there are different versions of the Tiger installer for PowerPC and Intel Macs. Apple never released a Universal Binary of the full installer, instead releasing separate PowerPC and Intel versions. Some later updates were available as Universal Binaries, but not the full OS installers.

Every Mac sold during the Tiger era came bundled with a grey Mac OS X installer DVD. These discs will reinstall the OS on that model of Macintosh, but they may not work with other Macs using the same processor. There is (I’m sure) an underlying consistency to what discs will work with what models based on system architecture, but these relations are often not user discernible. On practical level, it’s usually a trial-and-error process if you don’t have the right disc.

On the PowerPC side, the situation is easier. Apple sold several versions of Tiger at retail, culminating with a 10.4.6 full install DVD. These discs will work on all supported models of PowerPC Macs and are the best ones to have or try to find via resellers. The bundled install discs that came with G4 and G5 Macs do not work across the board on all models – again trial-and-error.

Upgrade Discs

Some PowerPC systems sold during the Mac OS X 10.3 Panther to Tiger transition included a Tiger Upgrade Installer for Macs with Panther already installed on the hard drive. These upgrade discs work with a wider range of Power Macs, but they require an existing Panther install to be present on the system before use. They also usually don’t offer the Full Install or Archive & Install options, just the Upgrade option.

In many cases upgrading (versus replacing) isn’t the ideal method to use, particularly if the older system is cranky and not performing correctly. For more info on this process, see Maintaining Your Macintosh: The Benefits and Possible Pitfalls of Software Updates.

Intel Macs

All Intel Macs came with their own (grey colored) Tiger install DVDs. Apple never sold a Full Installer for Tiger that was Intel-compatible. No need – if you were buying an Intel Mac, you automatically got Tiger, and if you had a PowerPC Mac, you wouldn’t need an Intel-compatible installer (nor could you use it).

This makes sense – until you need to reinstall Tiger on an Intel-based Mac. The original Intel iMac, MacBook, MacBook Pro, Mac Pro, and Mac mini models, which came with Tiger from the factory, all use different custom install DVDs. Most systems require their own discs, again hit-or-miss will apply.

I have had luck using the 10.4.10 installer that came with my Mac Pro to reinstall Tiger onto an early MacBook, but a MacBook Pro installer from the same era didn’t work. You do need the original discs – just at the moment (of course) when you can’t find those little envelopes that came bundled with the snazzy Apple cleaning cloth and window stickers you safely saved for future use.

Yes, you know they’re around somewhere….

DVD Copies and CD-Only Macs

Once you find (or borrow) the right installer disc(s), it’s a good idea to make a safety copy for future needs. Note that Apple does not use single-layer DVDs for these discs but rather dual-layer replicated discs, which require a dual-layer DVD-R or DVD+R recorder. Fortunately these drives and media are now commonplace (this was not true in Tiger’s early days). I’ve had good luck duplicating Tiger install DVDs using Apple dual-layer-compatible SuperDrives onto DVD+R DL media via the Copy mode in Roxio Toast software.

Another challenge: Many older G4 and G3 systems are Tiger compatible but only have internal CD-ROM or CD-RW drives. Apple did make CD copies of the Tiger installer available on a trade-in basis for a short time, but these are now very hard to find. The easiest method of (re)installing Tiger on a DVD-less Mac is to boot a DVD-equipped Mac into FireWire Target Disk Mode, connect the two systems via a FireWire cable, then insert the DVD into the newer Mac. The DVD will show up on the older Mac’s desktop, and you can proceed with the install.

As a consultant, I’ve used my laptop in the field many times in this fashion to help upgrade older systems. It’s a fantastically useful feature.

Update: A reader suggested an alternate solution to the DVD-less Mac install dilemma: Using Disk Utility on a DVD equipped Mac, he created a .dmg file of the Tiger install disk. He then restored this image across the network onto a small hard disk partition on the target Mac, selected this Installer Partition as the startup disk, and rebooted. In his own words: “Boom! It worked, and I had a functioning emergency boot partition acting as an OS X Tiger Install DVD. The speed differences were so noticeable, it was astounding!”

This is a clever solution. Restoring to an external FireWire drive would also work, from which you could boot up and install.

Install and Update

Once you have acquired the correct install disc for your model of Macintosh, go ahead and do a Full Install or (if you want to keep your old data) an Archive & Install. Once Tiger is installed onto the Mac, boot off the hard drive and then use Software Update under the Apple Menu or the Apple Software Downloads page to grab the remaining updates to get your system as current as possible. The last release is 10.4.11; you will want this update along with any QuickTime and Security updates and all or most Java and application updates. Typically I just get everything available. Several passes and interim reboots will be required to get all patches – keep checking Software Update until there’s nothing left to grab.

Eventually you will arrive at your Big Cat Destination. At the end of the process (and during), a glass or two of beer or wine may be helpful!

* If you are borrowing the install disc, we are assuming you are legally entitled to have Mac OS X 10.4 on your hardware but don’t have or can’t locate your original installer. Low End Mac does not condone software piracy.

[Editor’s note: This article is part of our series of articles on installing and upgrading to Lion (OS X 10.7). We also have a complete guide to installing and upgrading to Mountain Lion (OS X 10.8).]

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 install Lion 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. (Lion features a new recovery mode (also called Lion Recovery), but not all installations of Lion get it—and if your Mac’s drive is itself having trouble, recovery mode may not even be available. Also, if you need to reinstall Lion, recovery mode requires you to download the entire 4GB Lion installer again.) Finally, a bootable installer drive makes it easier to install Lion over Leopard (assuming you have the license to do so).

Thankfully, it’s easy to create a bootable Lion-install volume from the Lion installer that you download from the Mac App Store; just follow the steps below.

Update: When this article was originally published, the Mac App Store version of Lion would not boot any Macs released in mid-2011 or later, as those models shipped with a newer version of Lion preinstalled. However, unlike with the CD- and DVD-based Mac OS X installers of old, Apple can—and does—update the Mac App Store version of the Lion installer. So if you create a bootable Lion-installer drive using the current version of the Lion installer—which, as of 2/10/2012, installs OS X 10.7.3—that drive will work with all current Lion-capable Macs. If your only Mac was released after Lion, so you can’t download the Lion installer from the Mac App Store, I’ve also provided instructions for creating a bootable Lion-install drive for newer Macs.

Download Mac Tiger Install Disc Free

Part 1: For all types of media

1. Once you’ve purchased Lion, find the Lion installer on your Mac. It’s called Install Mac OS X Lion.app and it should have been downloaded to /Applications.
2. Right-click (or Control+click) the installer, and choose Show Package Contents from the resulting contextual menu.
3. In the folder that appears, open Contents, then open Shared Support; you’ll see a disk-image file called InstallESD.dmg.
4. Launch Disk Utility (in /Applications/Utilities).
5. Drag the InstallESD.dmg disk image into Disk Utility’s left-hand sidebar.

The next steps depend on whether you want to create a bootable hard drive or flash drive, or a bootable DVD. I recommend a hard drive or flash drive—a DVD will work, but it takes a long time to boot and install.

To create a bootable hard drive or flash drive

1. In Disk Utility, select InstallESD.dmg in the sidebar, and then click the Open button in the toolbar. This mounts the disk image’s volume in the Finder. The mounted volume is called Mac OS X Install ESD.
2. Click Mac OS X Install ESD in Disk Utility’s sidebar, then click the Restore button in the main part of the window.
3. Drag the Mac OS X Install ESD icon into the Source field on the right (if it isn’t already there).
4. Connect to your Mac the hard drive or flash drive you want to use for your bootable Lion installer. This drive must be at least 5GB in size (an 8GB flash drive works well), and it must be formatted with a GUID Partition Table. Follow Steps 1 through 4 in this slideshow to properly format the drive.
5. 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.
6. 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. However, with the 10.7.4 installer, you must use the mounted Mac OS X Install ESD volume or you will get an error at the end of the restore procedure and the newly created bootable drive may not function properly.

Part 2b: To create a bootable DVD

1. In Disk Utility, select InstallESD.dmg in the sidebar

2. Click the Burn button in the toolbar.

3. When prompted, insert a blank DVD (a single-layer disc should work, although you can use a dual-layer disc instead), choose your burn options, and click Burn.

You can now boot any Lion-compatible Mac from this drive or DVD and install Lion. You can also use any of the Lion installer’s special recovery and restore features—in fact, when you boot from this drive or DVD, you’ll see the same Mac OS X Utilities screen you get when you boot into restore mode.

Note: As explained in our main Lion-installation article, if you leave the Lion installer in its default location (in /Applications) and use it to install Lion on your Mac’s startup drive, the installer will be automatically deleted after the installation finishes. 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. One of these three procedures should get rid of the “Installed” status for Lion and let you download it. Update: Apple appears to have recently made this process easier: If you previously purchased Lion from the Mac App Store, the button next to Lion in the Store should simply say Download—click it to re-download the installer.

Updated 7/20/2011, 10am, to add note about moving the Lion installer package to prevent it from being deleted.

Updated 7/22/2011, 11:10am, to add instructions for forcing a re-download of the Lion installer, if necessary.

Updated 8/8/2011, 9:19am, with additional information about thumb-drive capacity and drive format.

Updated 8/19/2011, 2pm, to clarify compatibility.

Updated 2/10/2012, 12pm, with information about compatibility when using the latest Lion installer, and to note easier re-downloading of Lion installer.

Updated 6/27/2012, 9pm, to add note about Disk Utility error message introduced with the 10.7.4 installer, and 6/29/2012, 8:20am, to update instructions so they work when creating a drive using the 10.7.4 installer.
