However, if you are still not confident that you'll be comfortable with the new version or you fear any of your must-have software won't work properly on it, you can install Yosemite either on a separate partition or on an external USB drive and hard drive to check it first.
In this tutorial we will explain how you can keep both Mavericks and Yosemite on the same drive but in two different partitions or install Yosemite on a external USB stick.
How to Make Partition and Prepare Your Internal Drive for Yosemite:
By partitioning the drive, Yosemite will be isolated from already installed OS. If anything bad happens to the operating system, you can safely delete the partition whereas the actual OS will remain intact. Always back up your drive with Time Machine or with any other suitable option so that your data remains saved in case something unusual happens to the drive.
- First of all open 'Applications' -> 'Utilities' Folder and then double click on Disk Utility.
- Select your hard drive (HD) from the left bar.
- Click on 'Partition.
- Now click on small (+) sign.
- At this point you can give a specific name to the new partition and even resize it according to your need.

- Launch Disk Utility application as we mentioned above.
- Insert the USB storage in your PC's USB port and select it from the left bar of Disk Utility.
- Now click on Erase option so that you get rid of already installed stuff. You should use USB Disk having minimum 16GB free space for Yosemite installation.
- Under 'Erase', select 'Mac OS X Extended (Journaled)' and give the drive a suitable name. After that click on 'Erase…' button. This option will remove all the data from your drive. Make it sure you selected the correct drive to erase because there is no return point after that.
