  1. You must have a fully bootable Mavericks system from which to boot the computer. You can then erase the volume with Yosemite, then clone the Mavericks system to the empty volume you just erased.
  2. You can erase the drive and reinstall Mavericks if you have a USB Mavericks installer flash drive.
  3. You can boot the computer via Internet Recovery and reinstall the original version of OS X that came with the computer. This is only feasible on models from 2011 to the present.

Hi Allan. I just wanted to include my reasoning on why I'd like to return to my old OS over the Yosemite version. My email isn't working well.

I've tried everything to get my email to work but each time I check email I get an unable to connect warning. I then have to click take all connections online to try to get my personal email to work. I've gone over the settings to ensure they are correct. But since the upgrade this one particular account will not go online.


Regards,



Kelly

I've read about problem upon problem upon problem wt Yosemite. The really strange thing about the problems I've seen in this forum, is everyone seems to have different ones. No true speculation in this post, just a question to ponder. Did apple release more then one version of Yosemite to it's unsuspecting users for free, just to see what versions worked,and which ones did not? If anyone else has a similar question, please reply soon, because I am quite sure that Apple, who supposably doesn't read these posts, will have this question removed for speculating.

My biggest problem after upgrading to Yosemite is that my Yahoo doesn't work anymore. I cannot make conferences using Yahoo Conference ... it's what we usually use for our communications ... They continue to do so and right now, I need to get another laptop or computer to get in touch with them because I cannot force the majority to disregard yahoo just because I upgraded to Yosemite and that's my biggest frustration about Yosemite right now

Posting your question here at the bottom of this old thread is certain a good way not to get it noticed. I would suggest that you start your own thread for your questions. When you do include as much information as you can such as; the browser you are using, any error messages you are getting and how you are connected to the internet.


The stuff about your conference calls not wanting to switch from Yahoo is not help and can be skipped.

Hey Allan, I'm in the same situation, I have an old MacBook 2009 and since I installed the new OS X Yosemite, the battery just empties very fast...incredibly fast, I can't work without the energy power... it takes a lot to charge the battery but nothing to empty it....

So I think for MACs older versions the new system simply ruins your computer..so I want to come back to the prior operating system....
