Q: How can I uninstall OS X Yosemite and return to OS X Mavericks?

I don't agree with your statement.  There was a time pre-snow leopard at least when I took my old 2005 mac and was able to clone it operating system and all to my 2009 mac.  It didn't update the OS, it just cloned from one machine to the other.  Simple.  Straightforward.

Unfortunately, I guess I was correct. And, like MadMacs, I do not know how you could have accomplished it with a 2005 Mac. Their builds prevent them from booting from a build earlier/older than what they came with. FYI, here is a list of Macs and their builds which shows if one Mac might be booted with more than one OS:

So, exactly where are you at and what do you want to try next?

Glad you think that upgrading two applications is all I have to do as well.  You've been really helpful

Don't think you quite understood the situation.  When I turned on my new 2009 mac it asked (via text on the screen, and paraphrasing because it was 2009) "Is this your first Mac?  Do you have an older Mac?  Would you like to clone your old Mac to this one? Make sure your old Mac is turned off.  Connect a firewire cable.  Cable detected.  Now turn on your old mac while holding down the 'I' key (not sure, it might have been the "T" key).  Transferring your information, this will take about 3 hours"

That was it.  How perfect!  So here I am in 2014 with a Mac I can't clone onto new hardware.  That's not progress.  Next steps are to put in a call to Tech Support to see if they can think out of the lead-shielded, titanium lined box they've placed their paradigm in.  If they can give me a solution, great.  If not, I'll return the Mac on my way to buy some external drives that will get me by in the meantime.

Funny, Parallels says it won't http://forum.parallels.com/threads/parallels-desktop-8-and-yosemite-update.31229 8/

So now that I have a vague idea of exactly what it is you set out to do, there might be something out there that will do the job. You say you need more RAM than you can install in your 2009 MBP, so looking all that up I'm guessing that is more than 8.0 GB. It would appear that you can accomplish that by finding an Early 2011 MBP (which Apple only certified to 8.0 GB, but MacTracker says you can actually use 16.0). The Apple Store is down for maintenance at the present time, but that's the first place I would look for a refurb which will come with a like new warrantee that can be extended with AppleCare.

LOL those are exactly the steps I took to get to the circle with a slash through it.  hahaha

That was a migration not a clone, which is exactly what you could have done with your new one using either your old MBP or TimeMachine (which is a more recent way to do things).

You're close.  I have a 500GB hard drive that has 5GB free space.  It's not DRAM that's the problem it's storage.  The MBP I purchased has 1TB of storage, that would have bought me a lot of time.  So external drives will be the next step

Well the 'migration' downgraded the OS then.  Not many migrations I've seen have ever done that.

LOL, Have you read apples information about time machine?  They don't even guarantee it will work on the same operating system running on different hardware.    http://support.apple.com/en-us/HT201686.

Well it's clear from that discussion that Parallels isn't supporting it's use with Yosemite, but several users claimed that they were able to use it with whatever Windows version they were using at the time, so I guess it isn't really clear. RoaringApps has been wrong before, but they rely totally on user input so it's only as good as what is reported to them.

Well on that note, I'm signing off.  It's been interesting

Agree. You can also install a larger internal at some point and if you can spring for a large enough SSD drive, you'll enjoy an unbelievable speed boost.

Of course I've read that, but as I said it worked for me with for a three generation jump and from PPC to Intel, so it does work.

Note that Internet Recovery is different from the Recovery HD. It's <Command>-<OPTION>-R. It's supposed to kick in automatically on all modern Macs when no valid startup disk is available. OS X: About OS X Recovery.
