Q: What is best practice for installing Yosemite

I am currently on OS X Mavericks version 10.9.5 Macbook pro 13.  2.6 ghz intel for i5, 8gb 1600 mhz ddr3.

 

I am now downloading yosemite 10.10.1 but since i've been reading all these negative feedback so far, i am having second thoughts if i should continue to install the upgrade or not.

 

Any suggestion What is best practice for installing Yosemite?  Or is it not yet time to upgrade since the platform is premature yet?

 

Thanks in advance.

Mac Pro, OS X Mavericks (10.9.5)

    Regardless of whether we like Yosemite or not, the BEST practice is to have a complete Time Machine backup or other full bootable backup copy of Mavericks Before you try installing Yosemite. Even from Apple Store geniuses I've gotten conflicting recommendations about whether to upgrade or clean install Yosemite.

    If you have  a cloned back up, you can always go back and clone it back.

     

    Once Yosemite is installed, you cannot go  to App store and reinstall Mavericks.

     

    You can download Yosemite. Don't install if you don't want to.

     

    Once installation starts, please don't interrupt it.

     

    Sure, there are few minor problems and those will be ironed out in due course.

     

     

    Best.

    • Check your apps are compatible with 10.10 - roaringapps.com
    • http://www.etresoft.com/etrecheck can show what is running & installed - look for updates on the developer own sites.
    • If you have many kernel extensions or startup items look for updates to them too
    • Take a full bootable backup to another disk via Carbon Copy Cloner, Super Duper! or Disk Utility
    • Disconnect the backup before you begin any install (ideally set it aside & leave it untouched incase you need to go back to 10.9)

     

    Personally I prefer a clean install when there are signs of multiple migrations (if you have upgraded several OS for a period of years). Setup Assistant/ Migration Assistant can import user data from a backup, but consider that Apps & 'other data' should be manually reinstalled from the latest versions.

     

    If you clean install (erase the HD before installation) then make sure you deauthorise iTunes & any other apps that are associated online (like find my Mac).

    Basically the steps you would take before selling a Mac…

    Oh one more thing…

     

    Make a copy of your recovery partition NOW…

    OS X: About Recovery Disk Assistant - Apple Support

     

    That should allow you to reboot to recovery, download and install a clean copy of 10.9 if you ever hope to go back. Restoring an OS from Time Machine is not a 'clean install'.

     

    Life is easier if you have 10.9 in your App Store account purchase history - purchase every OS 'just in case' & back them up externally.

    One option is to create a new partition (~30- 50 GB), install the new OS, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won’t have to go though the revert process.
