Hello, I am using OS 10.9.5 which came pre-installed on my MacBook Pro Retina 15". Is it worth to upgrade to Yosemite? What are the advantages and disadvantages? I think the 3D dock will disappear in Yosemite. Shall I wait a bit longer before some bugs/compatibility issues have been fixed?

Having gone straight from Snow Leopard (10.6.8) to Yosemite (10.10.2) I must say the iPad integration with Mac is awesome! However, I had to go back to SL because some of my most often used and crucial apps would not run on Yos.

I am also waiting before downloading to Yosemite. Snow Leopard is just fine for me too.

For some strange reasons, my Mac is not very stable these days. For example, it happened twice that it did not respond to input from the internal keyboard. Few minutes ago, it even rebooted itself when I was working on an Excel document. Wonder if it is time to upgrade...

In case I decide to update, what do I need to do besides using TimeMachine to backup the Mac OS partition and WinClone to backup the Bootcamp Windows partition?

I would suggest a cautious approach to installing Yosemite:
  1. Clean install, don't upgrade on top of 10.9.5.
  2. Do a SMC reset and PRAM reset after installing Yosemite.
  3. Don't use migration assistant.
  4. Don't copy over system and library files from 10.9.5.
  5. Don't reinstall everything all at once. This will give you a chance to find any apps which could cause an issue with Yosemite.
  6. Only manually copy over user data that is needed. Leave the rest behind.

In fact I would suggest creating a second partition on your boot hard drive and clean install Yosemite on it. Play with the basic Yosemite and see if it performs well for you. This way you can always delete the partition when you are done.

Wow! That sounds serious!

I have already run into 2 third party apps that have caused an issue with Yosemite. And it was easy for me to isolate which apps were causing the issue and uninstall them. Not that you will run into any issues but just in case those steps I outlined should help increase the chances of finding an issue easier and earlier. It sounds like a lot but when you find a problem it will be easier in the long run. My $.02.

Thanks for those explanations. I had to look up what PRAM is and what a SMC reset is, so I've learned something I didn't know before. Still not entirely sure what a clean install is but I am staying with Mountain Lion anyway.

Once again, thanks to Taz Mangus for those explanations.

A clean install is:
  • Boot to the OS X I installer.
  • Enter the Disk Utility app within the installer and erase the hard drive where OS X is getting installed.
  • Have the installer install OS X.

A clean install puts a fresh copy of OS X on the hard drive instead on installing OS X on top of a previous install of OS X (e.g. Install 10.10.2 on top of 10.9.5).

A clean install can also be the following no...?

  • Run the installer from an existing OS X partition.
  • Direct the installer to install on an existing empty partition
  • No installer bootup required

Yes that is true.

Thanks for that, its a bit clearer. But I anyway will stick with Mountain Lion as Apple do not give the alternative of upgrading to Mavericks. It aint broke, so I don't fix it!
