I was able to install 12.21 no problem, but when i try to install 13, it doesn't work. I double click on the .dmg, and then it looks like something is going to open, but nothing does. nothing mounts either. I've tried restarting my computer. I was on an older OS, just updated to the latest and restarted my machine and still will not install.

I'm on 16" 2023 MacBook Pro M2, currently on sequoia 15.3.2.

Hi Alex,

That's strange. So you don't see 'PTGui install disk' in the Finder
under 'Locations' in the left side bar?

Could you try the following:

Open macos Terminal

Type the following, followed by Enter. This lists the currently mounted
disks:
ls -al /Volumes

Then, assuming PTGui_13.0.dmg is in your Downloads folder:
hdiutil attach ~/Downloads/PTGui_13.0.dmg

This has the same effect as double clicking on the dmg file. Then once more:
ls -al /Volumes

If you could copy/paste the output I might be able to tell more.

Kind regards,

Joost, thanks for the response.

before and after using the hdiutil attach ~/Downloads/PTGui_13.0.dmg command, this is the result:

alex@Alexs-MBP ~ % ls -al /Volumes
total 0
drwxr-xr-x 6 root wheel 192 Mar 14 15:49 .
drwxr-xr-x 22 root wheel 704 Mar 6 02:06 ..

drwxr-xr-x 4 root wheel 128 Nov 23 2023 Recovery
drwxr-xr-x 3 root wheel 96 Feb 3 09:07 com.apple.TimeMachine.localsnapshots

I've also tried installing "Ptgui_Pro_13.0.dmg" and doing this same method with the same results.

Hi Alex,

But what is the output of the hdiutil command itself?

On my computer it gives:

joostn@macmini:~/ > hdiutil attach ~/Downloads/PTGui_13.0.dmg
expected CRC32 $2D92D57F
/dev/disk5 /Volumes/PTGui install disk

And could you also check the file size using:
ls -al ~/Downloads/PTGui_13.0.dmg

This is what you should see:

joostn@macmini:~/ > ls -al ~/Downloads/PTGui_13.0.dmg
-rw-r--r--@ 1 joostn staff 78693366 Mar 14 09:20
/Users/joostn/Downloads/PTGui_13.0.dmg

Also PTGui 13.1 is out, perhaps this works for you? Even if that works I
still would like to get to the bottom of this, so the output of the
above commands would be helpful.

Kind regards,

13.1 won't install either.

I don't get anything in terminal (probably because it doesn't mount).
After i type it and press enter, seemingly nothing happens.

With 13.1, when i do it, i do get something:
alex@Alexs-MBP ~ % hdiutil attach ~/Downloads/PTGui_13.1.dmg
Checksumming whole disk (unknown partition : 0)…
...............................................................................
whole disk (unknown partition : 0): verified CRC32 $CC9C2604
verified CRC32 $2D65880B

after some time it gives this message:
hdiutil: attach failed - Operation timed out

If i check the volumes nothing shows up for PT Gui.

Hi Alex,

Could you run this:

hdiutil attach -verbose ~/Downloads/PTGui_13.1.dmg

and post the complete output here? The -verbose flag will cause it to
add some debugging information.

Kind regards,

Hi Alex,

I'm sorry, I have no idea what might be wrong, other than a corrupted
download. Which would be weird if it happened for both 13.0 and 13.1.

What's the size of the downloaded PTGui_13.1.dmg? It should be exactly
79,083,460 bytes

Kind regards,

A simple test before giving up would at least tell if the DMG file is corrupted on download or not.

I downloaded PTGui_13.1.dmg to my Apple Silicon Mac Studio (M1 Max chip) and computed a checksum on the file:

(base) Mac-Studio:Downloads jsimons$ hdiutil checksum -type CRC32 ~/Downloads/PTGui_13.1.dmg

...................................................................................................................................................................................

calculated CRC32 $CC9C2604

(base) Mac-Studio:Downloads jsimons$

Alex, if you run this command, it should generate the same value: $CC9C2604

I also verified that mounting onto my system Sonoma 14.6 system works:

(base) Mac-Studio:Downloads jsimons$ hdiutil attach ~/Downloads/PTGui_13.1.dmg

Checksumming whole disk (unknown partition : 0)…

...................................................................................................................................................................................

whole disk (unknown partition : 0): verified CRC32 $CC9C2604

verified CRC32 $2D65880B

/dev/disk9 /Volumes/PTGui install disk

Hi Alex,

It’s good news that the DMG is compatible with your kernel, which eliminates some issues.

I had a typo in that last command —sorry.

It should be:

hdiutil attach -shadow ~/Downloads/PTshadow ~/Downloads/PTGui_13.1.dmg

Joost I am getting the exact same behavior as Alex. I am running a Mac Studio M1 Ultra with macOS 15.3.2. I currently have PTGUI 12.27 installed. When I tried installing 13.1 the DMG won't mount. I then tried 13 and that won't mount. it appears your dmg have some sort of error. I have no trouble mounting a dmg from other software. Thought a reboot would help but. it did not. Previously I never had an issue mounting your dmg.

I see now that your output does not include the final line indicating what file system was actually mounted.

Since you and Michael are both running 15.3.2, I'm going to take one for the team and upgrade from 14.6 to see if I then also see the problem.

My system is a Mac Studio M1 Max.

I'll report back.

I upgraded to 15.3.2 and am now running the same build as Alex (24D81).

On my system both the generic and shadow versions of the hdiutil command correctly mount the disk image.

Well this has me scratching my head too. The dmg opens succesfully on
many computers running 15.3.2 on Apple Silicon, but not on some
apparently. Unfortunately I can't reproduce the problem on any of my
macs, which makes it difficult to diagnose.

@Michael and Alex:

If you go to macos Settings, Privacy&Security, do you have this selected?
"Allow applications from: App Store & Known Developers"

And I have created a .dmg file for testing, you can download it here:
https://we.tl/t-VqqOgckMJd

It is a volume named 'PTGui test install' containing just a single text
file. Are you able to open it, or does it exhibit the same behavior?

Kind regards,

I just tried installing on my MBP M3 Max running macOS 15.1.1 and PTGui 13 Beta 6. Same behavior. "App Store and Known Developers" is enabled. Test file will not open either. I was able to open 4 of the 5 other dmgs in my downloads folder. The one I couldn't I used last week no issues.

I ran the same command on my (working) system and compared with Michael's debug output below.

Probably no one else cares about this level of detail, but I'm sharing to document it.

The problem starts here when our systems are probed to see where this DMG was previously mounted on our systems.

Josh:

2025-03-29 15:46:33.132 diskimages-helper[61001:1634531] DIHelperAttach: performOperation: image previously attached as

2025-03-29 15:46:33.133 diskimages-helper[61001:1634531] {

"system-entities" = (

{

"content-hint" = "";

"dev-entry" = "/dev/disk8";

"mount-point" = "/Volumes/PTGui install disk";

}

);

}

And Michael's:

2025-03-28 12:43:10.946 diskimages-helper[82757:1521237] DIHelperAttach: performOperation: image previously attached as

2025-03-28 12:43:10.946 diskimages-helper[82757:1521237] {

"system-entities" = (

{

"content-hint" = "";

"dev-entry" = "/dev/disk15";

}

);

}

Notice that on my system it knows the previous mount point. On Michael's that information is missing.

Attributes for the disk device include:

Josh:

DAMediaWhole = 1;

DAMediaWritable = 0;

DAVolumeKind = cd9660;

DAVolumeMountable = 1;

DAVolumeName = "PTGui install disk";

DAVolumeNetwork = 0;

DAVolumePath = "file:///Volumes/PTGui%20install%20disk/";

Michael:

DAMediaWhole = 1;

DAMediaWritable = 0;

DAVolumeNetwork = 0;

Note that on Michael's system there is no volume information available.

This then turns into the fatal difference:

Josh:

2025-03-29 15:46:33.134 diskimages-helper[61001:1634531] _validateExistingMountPoint:/Volumes/PTGui install disk

2025-03-29 15:46:33.134 diskimages-helper[61001:1634531] _validateExistingMountPoint: _mountPoint=/Volumes/

2025-03-29 15:46:33.134 diskimages-helper[61001:1634531] -remountReturningDictionary: _remountDevEntries returned 0

2025-03-29 15:46:33.134 diskimages-helper[61001:1634531] _buildReturnDictionary:

2025-03-29 15:46:33.134 diskimages-helper[61001:1634531] _dictionaryFromDisk: adding (disk8): {

"dev-entry" = "/dev/disk8";

"mount-point" = "/Volumes/PTGui install disk";

"potentially-mountable" = 1;

"volume-kind" = cd9660;

}

Michael:

2025-03-28 12:43:10.948 diskimages-helper[82757:1521237] _mountDevEntries: skipping disk15 because it doesn't look mountable

2025-03-28 12:43:10.948 diskimages-helper[82757:1521237] -remountReturningDictionary: _remountDevEntries returned 112

2025-03-28 12:43:10.948 diskimages-helper[82757:1521237] _buildReturnDictionary:

2025-03-28 12:43:10.948 diskimages-helper[82757:1521237] _dictionaryFromDisk: adding (disk15): {

"dev-entry" = "/dev/disk15";

}

On my system, since it knows the mount point, all proceeds correctly and the DMG is eventually mounted. On Michael's, it gives up because it doesn't have the mount point information.

I should have added this looks like an Apple issue. And there are reports of similar issues from other users unrelated to PTGui.

I suspect if we could find a way to force the disk helper app to not reuse the last mount point, it would work correctly.

I’ve written to Apple, FWIW.

Hi Josh,

Thanks very much for investigating! But couldn't it be that the previous mount point is missing simply because it was never mounted successfully?

The DMG for PTGui 13 was built differently (genisoimage) than PTGui 12 (hdiutil). They have a different structure. Although both mount successfully (except for these 2 computers), I would need to find out if this is a factor.

On the other hand I also found a similar issue reported in the forums. It could be that Apple does some kind of virus scanning while opening the dmg file, which is failing.

Michael or Alex, if you could try mounting this dmg:
https://we.tl/t-VqqOgckMJd

If it is still problematic, I would like to open a support request with Apple, using this dmg as a sample. Could you do
hdiutil attach -debug ~/Downloads/ptguitest.dmg
and copy the entire output here?

Another thing to try: could you temporarily disconnect your wifi and then try opening the dmg again? If Apple is phoning home for a virus check, this might reveal it.

Kind regards,

Joost Nieuwenhuijse

Hi Joost,

I don't think that's the case. If you look again at this from Michael's trace:

2025-03-28 12:43:10.946 diskimages-helper[82757:1521237] DIHelperAttach: performOperation: image previously attached as
2025-03-28 12:43:10.946 diskimages-helper[82757:1521237] {
"system-entities" = (
{
"content-hint" = "";
"dev-entry" = "/dev/disk15";
}
);
}

You can see it states that the image was previously attached to disk15. It's the same in my trace, except a different disk and my results include the mount-point info.

On an unrelated and possibly irrelevant point, since Alex was initially reporting he was getting "no mountable filesystems" errors, I want to make sure you are aware of this information in the hdiutil man page:

No mountable filesystems

The "No mountable filesystems" error from hdiutil attach means that no filesystems could be recognized or mounted after the disk image was attached. The

default behavior in this case is to detach the disk image. See attach for options modifying this behavior. This error can occur if the disk image or

contained filesystem is corrupt. It can also occur if an image was created from a block device containing a mounted, journaled filesystem (in which case

the image contains a dirty journal that can't be replayed without making the image read/write, such as with attach -shadow).

I haven't used PTGui in a while and did not know V13 was out. I upgraded it, and it was installed without issues on my Apple M2 Max MBP/2TB SSD/64 GB memory with macOS Sequoia V 15.3.2.
