MAC RESTART CHOOSE STARTUP DISK HOW TO
Here's how to make it appear the way you want it to.A Troubleshooting Protocol to Identify Problems or Fix macOS El Capitan or Later Once you've chosen a startup volume/system, the computer begins booting into that OS and the boot panel appears. I'll talk more about partitioning in Appendix B.
MAC RESTART CHOOSE STARTUP DISK INSTALL
This situation is one where partitioning your hard drive comes in handy, as each partition is considered a different volume, allowing you to install a different OS on each. But if you need to boot into X in these particular circumstances, it's a handy tool.Īs you read the different options for choosing a startup system, you may have noticed that if you only have a single volume, and have both OS X and OS 9 installed on it (or two copies of OS X or OS 9), it's a bit tricky to switch between the two without starting up your Mac, and then using System Preferences to switch.
MAC RESTART CHOOSE STARTUP DISK MAC OS
If you last booted into OS 9 and you want to instead boot into OS X, you can hold the X key down at startup this boots you into OS X and changes the Startup Disk preferences to Mac OS X, making the change "permanent." You can't press the 9 key to do the opposite, and it doesn't let you change boot volumes it doesn't do anything else at all.
MAC RESTART CHOOSE STARTUP DISK MAC OS X
If you have a single volume with both Mac OS X and Mac OS 9 (the default installation on new Macs), and your Mac is one that can boot into OS 9, there's one other trick you can use, but it's a very specific trick that only works in one specific circumstance. In other words, Startup Disk settings in System Preferences remain until you change them selections made in Startup Manager only affect the current startup.

The next time you restart/start up, the volume/system chosen in Startup Disk preferences will be used. One other difference between using Startup Manager and System Preferences is that the volume you choose in Startup Manager is only used as the boot volume for that particular startup.

On earlier Macs, the option key does not invoke Startup Manager. Macs that can take advantage of the Startup Manager include all iBooks PowerMac G4 models with AGP graphics slots (including the G4 Cube) PowerBooks with FireWire ports iMacs with slot-loading CD drives and any Macs produced after these models.

(See Appendix B for more info on volumes and partitions.) Note that the term volume means any hard drive, removable disk, or partition. The volume JuniorX has two bootable systems, Mac OS X and Mac OS 9, but whereas both are selectable in Figure 3.1, only OS X is an option in Figure 3.2. You can see this difference by comparing Figure 3.2 (Startup Manager) with Figure 3.1 (Startup Disk in System Preferences) the same computer was used in both examples. In other words, if you have a volume that contains Mac OS X and Mac OS 9, and you most recently used that volume to boot into OS X, that volume will only show up once on the Startup Manager screen, and will only be selectable as a Mac OS X boot volume. I emphasize the term volume in the previous paragraph because unlike the Startup Disk pane of System Preferences, which allows you to select from multiple bootable operating systems on each volume, the Startup Manager utility only shows a single OS per volume-the one most recently used to boot up your Mac. (period) if you then insert a CD with a bootable OS that you want to select as your boot OS, be sure to click the rescan button to cause it to show up as an option. If you need to eject the CD/DVD drive from Startup Manager, press command+. You can stop this search by holding down the mouse button until you see the spinning cursor stop. This is because your Mac is searching for any connected network volumes that could be used to boot your Mac. If you use the Startup Manager utility to choose a boot volume, you'll notice that it often takes a long time before you can actually select a volume and click the continue button.
