Very nice, the only thing I don't like about it is that it hijacks the Finder while active. This is especially annoying when you are creating very big dmg's, since you can't use the Finder while it is working...

You are absolutely right about the Finder interaction and I know why...

I am working quite a lot time now and I hope to fix it soon...

Thanks for using the iDMG...

Let me know if I am correct!


Thanks Patrick, it seems to be fixed. Very welcome change!

Is the use of chalkboard font on some parts normal ?

Cause I don't see it in the screenshots and I don't like this font so much.

Better compression is HFS with UDZO with the slider to the right...! Not UDBZ

Version 2.1


HFS+ and UDBZ (slider all the way right) gave me better compression than UDZO.

After trying UDZO and setting the slider, the slider was kept to the right when I tried UDBZ.

I wish I could keep that setting (like a preference) every time iDMG is launched, since high-compression read-only dmg is what is most often needed.

All the best in your studies.


With v2.30 iDMG now retains the settings last used before quitting.

In iDMG Help, will you also explain the File System selections and their effects/consequences ? Thanks Patrick.

Hello i think the above explanation is good.

HFS+ is not case sensitive
HFSX is an extension to HFS+
HFS+J volume is journal
UFS is case sensitive

HFS+ supports both creation and modification
UFS supports modification dates but not creation dates.
HFSX allows volumes to have case-sensitive file and directory names.

HFS+J volume is the default file system for macs. The journal makes it quick and easy to restore the volume structures to a consistent state, without having to scan all of the structures.

HFS+J will keep the parent folder.
The other filesystems will get only the contents.

HFS+J is taking longer than the other filesystems.

let me know if you looking something else...
I'll add it to the next update


Thank you for the new Help information.
