All of us here at Software Voucher primarily work on Mac’s so without Parallels (or VMware Fusion, some of us use it instead) we would have to switch to our PC’s when writing most of our software reviews and testing the new releases. But with that said, there are a few things that really bug us with program. Here are the top things that we would love to see changed in version 11:

Stop forcing the upgrades – When you buy Parallels be aware that it’s not a program that you buy once and that’s it; Parallels provides operating system support only for two versions back of the software. So in essence, if you’re upgrading your Mac OS at every annual release, your version of Parallels will require you to pay for an upgrade every 12 to 24 months (depending on when you bought software) for $50.00 per computer. If you happen to upgrade your OS but not your copy of Parallels, and you’re running a version that’s not supported anymore by the new operating system, then you won’t be able to run Windows at all anymore, holding all your stuff hostage. The folks at Parallels argue that they need to have this policy to help pay for development costs… but in all reality, the two-version back expiration policy is way too short. And when you think about it, when was the last time you bought a mac software program that just stopped working when a new OSX was released? It’s never happened to us aside from Parallels.

Remove the in-product ads – Parallels takes advantage of the intimacy that their software has with your Mac and uses it to serve third-party ads to you (kinda like an adware). And it really doesn’t matter what you’re doing, like watching a movie, editing some photos, or answering emails, it’ll pop up here and there randomly trying to sell you something (for us, it’s often some Kaspersky antivirus software or telling us to upgrade our copy of Parallels). Now you can select “don’t show me this again” when the ads pops up but you can never turn it off completely in the settings. Customers have been asking for this shady advertising practice to be removed for the last few versions but it seems to only be getting worse.
Too many icons – If you’ve upgraded from version 9 to 10, then one noticeable difference you’ve probably seen is the extra icons in your dock – You now have the Parallels icon and the Virtual Machine icon. That means that you now a few extra clicks to close the program down when you need to shut down. We find no practical use of have more of “Parallels” in our face in the dock.

Slow performance in coherence mode – Coherence mode is pretty cool and we were supper excited when we first learned of it (this is the new feature that makes your PC programs look like native Mac apps in the dock). But the problem for us is that it just seems to slow everything down when it’s on. Granted that most of us are on rather lower-ended

MacBooks but still, performance really suffers.
Better battery life – Parallels focused on performance in this last release and overall they were able to beat VMware in most tests. But this can at the price of batter life and overall stability. We hope that at the very least that they can get battery life more in par with

Fusion.
Offer more licenses for users - If you have just one Mac at home, the upgrade cost can be swallowed. But if you have several machines in your household, maybe even multiple per head, then these costs rack up fast as EACH upgrade or full version of Parallels will only let you install the software on one machine. We would love for Parallels to let users to install the program on all of the purchasers personal computers at home just like VMware lets you do.
