From BurningThumb Software:
Virtual CD RW Mac is an easy to use virtual CD drive for Mac OS X 10.6 or later. It uses a disk image, but appears to Mac OS X as if you have inserted a CD, so you can read from it and burn to it even if you don't have a CD drive, but 10 times faster. Easy to use, it appears in the menu bar and then you can mount and read any Virtual CD or use the Virtual CD burner from the drop-down menu. Use it with music converter software instead of using a physical CD because a Virtual CD burner is 10x faster. Make virtual copies of music CDs or other CDs for faster access and to protect the original CDs. Erases Virtual CDs, too.
Your Mac may not have a CD drive, which is a problem if you're trying to use an app that burns to a CD or CD RW. You can't use a disk image (.dmg) file created by the Mac OS X Disk Utility instead, because a .dmg does not appear to be inserted in a real optical drive to your Mac. You could use an external CD drive, but they are much slower than an internal CD drive. Or, you could use a virtual CD drive app, like Virtual CD RW Mac. Because Virtual CD RW Mac is a kernel extension (driver), it looks exactly like a physical drive to all applications running on the Mac OS. And because it stores the virtual CD data in a file on your hard disk, it is much faster than any actual CD drive, whether it is an internal CD drive or an external CD drive.
Does what it claims. Works very quickly (MacBook Pro with SSD) - *much* faster than mucking around with actual CDs. Very simple interface via a new icon in the menu bar. Free trial works well. Works fine in OS X Mavericks.
Virtual discs are limited in size to standard CDs. I would have liked if larger discs (e.g. DVD or bigger) were possible, but this was not critical for me.
One click on 'New Media' inserts a (virtual) blank CD for burning. The disc can then be re-ripped before ejecting, if desired. Ejecting the discs prompts where to save the image. The disc image can be re-opened later.
Clicked on New Media and...nothing happened. Unable to create a new disk image. The "Open Existing Media" seemed to work in that it popped up a dialog box, but of course without being able to create new media I couldn't really test existing media...
Seems like a great idea, and I'm glad it helped for somebody, but version 1.2 did not work for me under OS X 10.7.4
There are only two reasons why I leave reviews: either I love the product and want to preach its virtues or I hate the product and want to warn others.
I can honestly say that this is the first time I have felt ripped off by an OS X developer. In short, this software does not work for long. I downloaded the demo and that proved stable and functional. However, when I purchased the license, the app stopped working after about a week and reverted to the nag of "Buy Now" or "Quit" in the drop down menu. I contacted the developer who advised that I must have downloaded an "old" version (I had previously downloaded directly from their website). Reinstalled the app and that resolved the problem for about two days this time. Several re-installations later and the app just doesn't work. Very disappointing! I've given up and written it off completely.
