A “startup disk” is a volume or partition of a drive that contains a bootable operating system.
You can set your Mac to automatically use a specific startup volume, or you can temporarily override this choice at startup.
- I'd say it's probable that the files on my memory stick are from 6.1 given their date stamp. (BTW I'm on a mid 2014 13' macbook pro). Running Apple Software Update doesn't do anything BTW. At this point I'd like to blame the BCA procedure, but it looks like the Boot Camp Installer isn't programmed to check if the existing installation is old.
- Mac Boot Disk free download - Disk Drill, Auslogics Disk Defrag, Wise Disk Cleaner, and many more programs.
- From the Apple menu choose System Preferences.
- Click the Startup Disk icon in System Preferences, or choose View > Startup Disk.
- Select your startup disk from the list of available volumes.
The next time you start up or restart your computer, your Mac starts up using the operating system on the selected volume.
Temporarily change your startup disk with Startup Manager
Startup Manager allows you to pick a volume to start from while the computer is starting up.
Use these steps to choose a startup disk with Startup Manager:
- Turn on or restart your Mac.
- Immediately press and hold the Option key. After a few seconds, the Startup Manager appears. If you don’t see the volume you want to use, wait a few moments for Startup Manager to finish scanning connected drives.
- Use your mouse or trackpad, or left and right arrow keys to select the volume you want to use.
- Double-click or press the Return key to start up your Mac from the volume you selected.
If you have an optical drive connected to your computer, you can insert an installation disc to see it in Startup Manager. You can also attach FireWire or USB external hard drives that contain an operating system to add to the list of startup volumes.
Startup Manager automatically adds bootable volumes as you connect them.

Restart in OS X from Boot Camp
If you have started up your Mac in Windows using Boot Camp, you can use the Boot Camp system tray to switch your startup disk default back to OS X.
- In Windows, click the Boot Camp icon in the system tray.
- From the menu that appears, choose Restart in OS X.
Start from OS X Recovery
You can also start your Mac from OS X Recovery or Internet Recovery if your Mac was manufactured after 2011.
To start your Mac from the Recovery System, use these steps:
- Start up or restart your computer.
- Hold down the Command and R keys on your keyboard until you see the Apple logo appear onscreen.
If you don’t see a volume listed
If you don’t see the volume you want to start your computer from, check the following:
- If you’re using an external drive, make sure it’s connected and turned on.
- Make sure you’ve installed an operating system, like OS X or Windows on the drive you’re trying to start from. Volumes that don’t contain a valid operating system aren’t listed in Startup Disk or Startup Manager.
- If you’ve installed an operating system on a drive but it isn’t listed, the volume you’re trying to start from might need repair. If the volume contains OS X, start your computer from OS X Recovery and use Disk Utility to repair the volume, or reinstall OS X on the volume using the Recovery System.
- Depending on the Mac you are using and the version of OS X that is installed, the Recovery System volume (Recovery HD) might not show up in Startup Manager. Press Command-R during startup to start your Mac from the Recovery System.

I have looked for a while now. I have found a download page here:
The latest date on anything I can find here is from 2015.
Another page directs me to use the boot camp assistant, but it requires that I have a thumb drive (ready to be reformatted), and I must reboot into MacOS I'm not going to do that. In anticipation to some responses, we can argue about it if you want but it'll be a waste of energy.
Many other situations would involve going to a web page and downloading an installer so I'm asking here for what I'm missing.
Thank you for responses that stick to the point and answer the question.
I felt like showing a bit more of the process:
1) 'install Windows on a Mac with Boot Camp Assistant' https://support.apple.com/en-us/HT201468
Ok this looks useful but the process is written for a fresh format and install of Windows.
Here's a link for:
2) 'If the Boot Camp Installer Doesn't Open...' https://support.apple.com/en-us/HT208495
Ok that's cool now I know I'm looking for some 'Boot Camp Installer' that needs to run on my Windows side
3) But of course there's no link to a 'Boot Camp Installer' I needed to use the Assistant from the MacOS side and the thumb drive.
4) Wait wait, here's a section called 'If you can't download or save the Windows support software:'
Oh, but this section just troubleshoots problems you have with formatting your USB drive and with USB drive recommendations.
I don't know why it's like this. Any other system would just have an installer and even an update agent for download. Is apple protecting IP and software licenses. Possible. Are they keeping users from downloading the wrong versions of stuff? Possible but there are other ways to do that.
They made a choice to handhold users through disk formatting instead of just having a download.
