I have a 2TB USB 3.0 drive connected to my iMac. It is presently divided into two 1 TB partitions. One I am using for storage of stuff. The other partition I could blow away to install Mavericks on if it is possible to do this and boot from that partition at will.

Can I do that? If so, how do I go about it without screwing up my current install on the local hard disk. I own Mavericks and I think it is available as a download in my purchase history on the Mac App Store. I'll have to check but I think that is where you go to retrieve past versions you are licensed for isn't it?

I just want to be careful that if I tell the App Store to download and install that that it does not install itself to my present startup disk which would cause me terrible pain and suffering, etc.

Yes, it will be exceptionally easy if you have a spare 8 gig flash drive.

Download the Mavericks installer from the App Store.

Download http://diskmakerx.com

Make a 10.9 flash drive.

Boot to flash drive, run through installer selecting your desired drive.

Profit.

Thank you very much sir. You are a gentleman and a scholar!

I just checked and my local Walmart has a nice USB 3.0 16 gig one for under 10 bucks in stock at the store so I will pick that up tomorrow when I go out shopping with my sister. It's going to be nice to see Mavericks again. :D

When Mavericks finished downloading from the App Store it tried to open it and I got an error message informing me that "This Copy of the OS X Installer Application is Too Old To Be Opened On This System."

Hopefully that doesn't matter when DiskMaker X does its thing to create the bootable installation on the flash drive?

As long as the system originally came with 10.9 or earlier you'll be fine. All disk maker X is is a wrapper for the following.

i.e. it's easier to use disk maker X.

Thanks. I know I upgraded to Yosemite on this late-2013 iMac so I think it must have arrived with Mavericks when I got it. I think I had upgraded the mid-2011 iMac to Mavericks not too long before it bit the dust entirely and was replaced with this one. So I should be good there.

I did download and install Disk Maker X so I'm good to go there. I just need to grab the USB flash drive and I'll get it done.

In the interim since it was already installed I fired up Company of Heroes and played a skirmish game. Amazingly I won it on normal without having done the tutorial and knowing what i was doing. Pretty funny. I had to scramble at the end but at least I had the sense to capture resources that saved the day early on. That was my salvation. I felt pretty good about that. :D

It ran fine but I was not playing a real long time. The problem it has I guess is slowdown after some period of time playing. I'm still going to just set it up where it is known to work right and skip the hassle. It will be good to have Mavericks around for times when I encounter something that doesn't work in El Capitan, etc. with so much to catch up on.
