Create RAM Disk in OS X:
diskutil erasevolume HFS+ "ram disk" `hdiutil attach -nomount ram://4629672`
This makes 2.2GB. Alter the bits if you need more or less space. Use with Photoshop and the like as scratch. Super fast. If you need more than that, buy this I guess. But Mac OS still allows you to do it for free.

Version 1.2.9

No, not exactly the same: Der~bot~haus' procedure makes the ram disk here:
/Volumes/ram disk
...to which a symlink must be made to substitute for Photoshop's scratch disk, or at least make sure RAM disk is mounted before launching Photoshop if directly designated in Photoshop's prefs.
RAM Disk Utility Pro, on the other hand, does something more sophisticated: it changes a folder of your choosing into a mount point for the RAM disk, and you can make any number of them for various apps' temp files.

The interface is so complex. I don’t think this utility is necessary for me. If I need to choose a Ram monitor, I would rather choose istat menus and many other apps than this one.

This app seems to be just for creating, managing en monitoring Ram DISKS, I don't think it's an ordinary Ram monitor like iStat or meant to be used like a Ram monitor. But indeed the crowd that needs Ram disks under OS X these days seems very limited.

English is an options, but a suggestion to the developer before I properly evaluate it: default to English on the first language selection menu rather than Chinese.

Three updates and the only thing I have gotten so far is a strange looking window with all Chinese symbols.

The same error message was at least in English. nilobjectexception. Whatever that is supposed to mean.

Seriously? The author wants me to pay $15 for this lousy excuse of a one-trick pony.

This is what I see every time I have tried this useless software - http://i53.tinypic.com/upu89.jpg

If you have this problem, try deleted ~/Ram-Disk/Ram Disk Utility.conf , and run again. In normal, language will change after into program. http://i.imgur.com/ZLi4t.png


I had a look at http://i53.tinypic.com/upu89.jpg and one can read "NilObjectException", therefore it probably is a RealBasic application...

delete ~/Ram-Disk/Ram Disk Utility.conf

Let me go a little farther. Okay, I launch the program and it gives me the option of selecting English. So I do. But all the menu items are still in Chinese. For all I know to the contrary, this may be a great program. But I have no idea how the hell to use it or what I'm supposed to be doing, and so I close the program and trash it. You can your fifteen bucks goodby, developers (and I wonder how many lost potential customers this statement has to be multiplied by).

Im not sure what the purpose of this program is...?

I remember back in the day like OS8/9, we would make RAM discs and have the web browser store its cache there, so the pages would load WAY faster. I see in the screenshot that you have Safari and Firefox on the ram disks. Can you do something similar with this?

Creat RAM Disk is really easy on OS 8/9 because it's a build-in function. But it's NOT build-in on OS X.

It's not easy to make and manage multi RAM Disk, even on OS 8/9. And it may something wrong when RAM Disks full but programs still try to write into it.(Such as Safari, if its cache has no free space, Safari will use almost 100% CPU, and system become hang.)

RAM-Disk Utility is my answer for RAM Disk Usage.
Configure many RAM Disk's setting, and create,remove,automate with those setting.
