Hi peeps!

Before I lose the plot completely - hoping you may be able to help. For the first time, I have produced a disc to a client who has a Mac and is unable to open the Jpeg images on her computer! I use windows/photoshop CS6/Lightroom.
Saved images on disc as I normally would but cannot find how to "convert" so she is able to pick them up on her mac??? I have emailed her digital images, but she is requesting a disc also!
Hope someone can shed some light as to how I can do this? OR is there something she can do her end?

I heard there can be a problem in the suffix, .jpg or .jpeg, reformatting usually works but I have no personal experience of this.

hope this helps


That's all about going the other way: opening files on a PC that came from a Mac.

Unless the Mac is rapidly approaching 20 years old, there should really be few problems opening a JPEG file.

You need to establish, in order

1) whether the disc mounts on the desktop

2) whether the files are visible on the disc

3) what she is doing next to open the files (e. g. Simply double clicking on them) and what happens when she does (what application attempts to open them and is there any error message shown)


If steps 1) and 2) are OK, your client might try opening Preview.app (in /Applications/) then go to Open from the File menu and navigate to the JPEGs on the disc.

Also, does anything change if she copies the files from the CD/DVD to her Mac's hard disk?
 
True, but it is very rare for a Windows app to save a file without an extension.

It's also a lot rarer on Macs these days compared to, say, ten years ago.
 
It's never happened to me , I've always used macs, I mean I've had things not open because I don' t have a right copy of the prog it originated in
but I'd always assumed part of the point of jpegs were they were cross platform. So I have now asked my partner , she designs magazines, and she said it has happened to her before and it was something to do with the suffix being different but happens so rarely that she could not remember the details of correcting it, not much help to the OP I know but interesting as I had not come across it before. Just checked and all my cameras label them in upper case JPG and photoshop in lower case, jpg hmmmm. and then I saved a pic using preview both jpeg and jpeg2000 and neither has the suffix on the file name. I am rambling now, I really want to know the answer now :)
 
You can force an application (such as Preview) to open a file by holding down the Option key while dropping the file on the application's icon in the Finder or Dock.

This should work if it's a valid JPEG, regardless of whether the file extension is correct, or even missing.

Mac OS X file extensions are not case sensitive, so both .JPG and .jpg are valid.

Similar for three letter (DOS) vs four letter (UNIX) extensions - .jpg/.jpeg are both valid (though three letters is the default).

Whether you see them or not on any particular file depends on the settings for that file (File > Get Info > Hide extension) unless you have your Finder prefs set to always show them (Finder > Preferences… > Advanced > Show all filename extensions).

When saving from Preview you probably have the 'Hide extension' checkbox checked at the bottom of the Save dialog, which is why you're not seeing it.

So.. can she see the disk on her desktop or not? She may say "I can't open the images" but that may well be not what she means. I find it very unlikely she can't open JPEGs, but depending on how you burned the disk, I can imagine it won't mount on her desktop.

How did you burn the disk?

Excellent ! I never knew that, Thank you,

all files are now with extensions, looks much more professional :)

sorry to the OP for hijacking the thread
 
Many POSIX systems (unix, linux, osx...) don't use the file extension, they use the file type identifier in the file header.

Indeed, though four letter extensions tend to derive from UNIX family OSes rather than Microsoft ones. Windows NT was technically POSIX compliant IIRC :)

'Classic' Mac OS prior to OS X stored file type/creator along with other metadata in a separate Resource Fork within the file (with no file extension), though this usage is now deprecated it is still available for use on HFS and HFS+ formatted volumes.

How did you burn the disk?

Hi - I burnt the disc as I do with all my work. The disc was entered, formatted, and then I sent images to that disc. It formatted before ejecting etc. I may try a USB Stick? Its very frustrating for want of just going to her home and doing it for her?!
 
For compatibility with other OSes and older machines, I never just use Windows t burn a disc, but use a dedicated disc authoring programme. I use Nero. You can set the actual disc formatting parameters, and burning a disc in ISO9960, or UDF flle systems helps with older Macs.
 
We still haven't established whether the disc mounts on the client's Mac, and whether the files are visible on that disc in the Finder.

Dare I say, as someone who does it every day, troubleshooting is largely a question of obtaining an accurate description of the problem and then eliminating each of the possible causes until one remains. Once that is identified, then it may be possible to suggest a remedy.
 
Many years ago, I had cause to resolve a similar problem - a CD full of files, but none would open.

The well-meaning sender had carefully named, categorised, and organised a load of files, then diligently burnt a CD containing nothing but shortcuts to the files.

Looked great at their end, not so much at the recipient's.

Not being aware of your client's computer ability, this may not be feasible, but rather than travelling to her home, have you considered using remote access software to understand what is happening?
If it were all windows, I would recommend ammyy (http://www.ammyy.com/en/) which is very easy to configure, but it's not, so something like VNC (http://www.realvnc.com/products/vnc/) perhaps?
At least that way you could acurately see what is going on, rather than simply being told she cannot open them.
 
If you have a Hotmail account you could upload them to One Drive (used to be Skydrive) then simply share them with her using her e-mail address.
That way she could see the images and save them to her Mac while you try and sort it out.

She is uploading the disc and seeing that the images are available but when clicking it is simply saying unable to open file. I have Nero and will try and burn through that instead.
