No, Parallels doesn’t messup the Mac OS system at all, it keeps the Windows side self contained. It will roughly take up 5-8GB plus whatever Windows software you are looking to install like Outlook, Powerpoint, etc. Parallels is a worldwide leader in automation and virtualization software that optimizes computing for consumers, businesses, and service providers. It allows you to run Mac virtual machines and virtual PC. Parallels Client, when connected to Parallels Remote Application Server (RAS), provides secure access to business applications, virtual desktops, and data from your device. Using virtualized applications and desktops on Parallels Client is intuitive, fast, and reliable.
I use Parallels on my iMac and Macbook Pro. It seems to run fine on my iMac but kind of causes my MBP to become a little sluggish and fans to get pegged. I was speaking with someone that runs several VMWare VMs on their Macbook without any problems at all. They mentioned my MBP should have more than enough resources to handle several VMs.
Does VMWare generally perform outstandingly better than Parallels on Macs?
Here are my machine specs (both running OS X 10.10.3):

Parallels on Mac has a better performance. It integrates with OS X in a way which is not possible with VMware. I am using parallels with multiple VMs without any problems or sluggishness. I have allocated 3 GB RAM to each VM. Check how many CPU cores you have allocated to your VM.

I have run both VMWare & Parallels on 11' MacBook Airs - and on my current 12' MacBook.
(with 2, 4, then 8gb). Then only performance problem I have had - which is ongoing - is when I switch to retina mode in the VM (on my 12').
This is substantially slower - especially on Parallels - often locking up for 5-10 seconds. I don't know if this is a driver thing - or if retina displays just require a lot more horsepower which lower end macs (and even higher end laptops) just don't have.
I may try a new high-end MacBook Pro to see if this fixes it.
