Modification Date changes when updating Open With?!?!

Forgive me if this is mentioned elsewhere. I have been searching these forums and not seen this problem.
If I do a 'Get Info' on a file in the Finder and change the application it opens with, the Modification Date changes to 'now'. Why in the world would this happen? This is not how 10.3.x worked, and certainly doesn't make any sense since I am not actually modifying the file. I am simply changing the OS's metadata about which app to use. This info isn't even stored in the file itself, as evidenced by burning such an document to a CD or moving it through a network server then opening it on a machine with different default apps for certain extensions.
Is this just another wacky step backwards in the world of the Apple OS X Finder, or am I missing a way to avoid this?

This is not how 10.3.x worked, and certainly doesn't make any sense since I am not actually modifying the file.
Actually, I am using "Panther" now, and can confirm that changing the application to be used to open an individual file through "Get Info" does in fact change the modification date.
When the "Change all" button is used, the modification date of other files of that type won't be affected by this change since that modification is presumably made somewhere in the "Launch Services" database to set the "default" application to be used for that file type. Perhaps this is what you were thinking of.
However, for that first file (or any file changed individually), the file is in fact modified, and the "Open with" information is stored with the file, in its "resource fork". Usually, a 'usro' resource (specifying the application) and an 'icns' resource (for the app's custom icon for that file type) are added. You can try this yourself - drag any image from Safari.app to the "Desktop" and open the info window for that image - such images usually don't have a "resource fork". Make note of the file's size, then change the "Open with" application. You should immediately see an increase in the file's size (to account for the addition of the "resource fork") accompanied by an update of the file's modification date to reflect this modification.

Modification dates change when moving/copying between hard-drive and flash

I use a flash drive to store most of my work-related documents on. That way, I have them when I'm at school (on a Windows XP computer) and at home on my Mac OS 10.3.9. I
try to occasionally back-up my flash drive by dragging it's contents to my Mac. Copying in this direction USUALLY retains the appropriate modification date.
However, if I move things from the Mac to the USB drive (I occasionally make changes to a file on the Mac when my flashdrive isn't handy), the modification date changes to the copy/move date. Is there a way around this? It alters the information about the file and sometimes makes a version look newer than another version of a document. When in reality, it’s older--it’s just been moved/copied and the date changed.
I often move things back and forth for backup purposes, but if it keeps changing the dates on it’s own, it’s impossible to tell which is REALLY the
most current copy/version.
Is there a fix so that copying and moving files between volumes does NOT change the modification date of the file?

Hi, teacher. When my Lexar JumpDrive Secure is formatted as a MS-DOS volume so a PC can read it, the last-mod dates of files that I copy to it are changed to the date and time of copying. When it's formatted as a Mac OS Extended volume, the original last-mod dates are copied to it unchanged. Looks like you can thank Bill Gates for the inconvenience: apparently it's a DOS file system "feature". Don't you wish you could use Windoze all the time?
On second thought, the files really are changed when you write them to a DOS volume, because the DOS file system has no place to store the metadata about your files that a Mac pays attention to and a Windoze box doesn't. So when you write Mac files to a DOS volume, that metadata — which is part of each Mac file — is simply discarded, causing the last-mod date to change.

Modified date changes when just opening PM file

We use modified dates frequently at my business. We have lots of things that reoccur only once a year, and we'd like to keep the file dates listed as such in the folder views.
All the sudden, however, Pagemaker files have started updating the modified date to the moment you touch the file, even if you make no changes. If you open it, it now becomes today's date & current time. It's really messing up our method of doing things.
It's not happening with any of our CS4 files, or any Microsoft Office files. Also, it's only happening on files stored on the server. It doesn't happen when we do a test of saving a Pagemaker file locally. The problem is, we don't store anything locally. Everything is stored on the server so everyone can access the file and so it's backed up.
We have a Windows based computer environment but an Apple server with OS 10.3.8 (Tiger--- yeah, I know, old, but it's as far as we can update that server at this time and are looking at getting a new one sometime, but it might be a year or so.)
The "modified date" problem has taken place only in the past 2 weeks. We have not done anything significant for changes or updates for quite a while on either the local computer or server ends. We restarted the server recently just to refresh things, and also added another user to the server and set some permissions for that user in the past 2 weeks.
What could be causing this all of the sudden, and how can it be fixed?

Acrobat 9 makes PDF versions 4.0 and higher. You need a PDF version 5.0 to handle transparencies well. PDF version 4.0 doesn't handle transparency effects well at all.
Pagemaker needs Acrobat 5 to be able to directly export PDF's with custom job settings. It only generates a PDF version 4.0, but works for our needs in Pagemaker.
I choose to keep both Distiller versions to make our work easier. When you have 20 ads open in Pagemaker, and you send the first one as a postscript through the print window, it sets up the "File, Export" in Pagemaker to use the correct PDF job setting, and then you can just do "File, Export to PDF" for the next 19 ads and it makes perfect PDF's. Works slick instead of having to make postscripts of all 20 ads first and then run them through Distiller. If you only have Distiller 9 installed, it doesn't let you select any custom job settings from your Distiller. Crazy, I know, but that's what I've figured out we have to do to get it to work. Have to have Distiller 5.0 to control PDF settings in Pagemaker and still be able to export from the file menu directly to PDF.
Distiller 9 is used for all other more advanced design pieces created in InDesign or Photoshop that are saved as a postscript first and PDF's are made the long way in those cases (running postscript through Distiller 9 at the end).

Documents "Modifed Date" changes just by opening?

We're seeing that Word, Excel & various other doc's change their "Date Modified" to today's date where they are ONLY opened...not modified.
All we're doing is opening and closing, no changes....
Is this a Micro$oft issue or can I change a preference somewhere??
many thanks

After seeing that the date-change problem seems to happen when you look at a document to which you have group access, but you aren't the owner of it, I just tried marking a similar document "read-only" using the Workgroup manager, then I went back to my desktop machine, opened it in Word, closed it again, responded 'no' to the dialog question about saving, and this time the date didn't change - and there was no MS Word error message..
I'm haven't tested what happens if you try to do the same in finder from a client machine -- of course, usng Work Group manager that way is not really a practical solution.
Also I'm going to see if the problem happens with a non MS Office application.

Modification date changes although nothing changed

Hi all,
any time I open a document with pages the modification date changes although nothing was changed.
This is not very logical and I don't like that behavior.
I wonder if it is possible to avoid this.
Any clues?
Greetings, Ronald Hofmann

Yes, of course, what else. Thank you.
There is only one date shown at all.
It shows when last opened and when last changed.
But in my opinion it's not very important when it was last opened.
Much more important is the information when the document was changed.

After editing file in ACR 8.6 (Mac) , the file (NEF and XMP) modification dates are not updated

With both my Mac's, reset Photoshop C (2014) to previous version 2014.0. Now find that after editing file in ACR 8.6 (Mac) , the file (NEF and XMP) modification dates are not updated. Reloaded camera raw, etc., but still find modification dates are not updated, either using Finder or using Bridge to view dates. Editing other files, PSD, DNG, TIFF, etc., are updated and the information is correctly displayed.

Ok, not entirely sure what I did but it's now working (Bizarre!). The only thing I did was 'eject' the ACR 8.6 .dmg file from the finder side bar and restart PS CC, so that may have been where I was going wrong all along!
However, I now have another issue in that there is no preview of the shot in Finder on my iMac when I highlight the NEF file. I assume this is simply because Apple haven't yet released an update for the new D810 NEF files and so the computer doesn't know what it's looking at?!?
If anyone has any other ideas though, then I'm more than willing to listen.
Thanks again.

I have a mac air and an iMac and both have Pages. I use Pages on my air and save all documents to iCloud. I can see them on my iMac but it won't open with Pages. It becomes visible if I change it to open with preview but I can't interact with it.

I have an mac air and an iMac 5k - pages runs on both. I use pages on my air and save all my documents to iCloud drive. I can see the documents on my iMac but some won't open in pages which is bizarre? They will open if I change it to open with preview but then all I can do is read it - I can't add to the document - All I want is to be able to see all my documents on all my devices and to be able to have them sync so I can add to the documents from any of my devices. I also have an iPhone 6 and an iPadair2 but I would be happy just to have the iMac and macair sync for starters. I have folders within folders in my documents,. The folders which contain pdf's and individual files open OK . The one I am having difficulty with is the file which I use for ongoing correspondence - in other words it is quite long - I keep adding to it ( by copying letters in and letters out so I can see a sequential history of what has been going on by scrolling down ) in date order so that it could be 1 - 100 pages long - but I don't think the size is a problem. I don't understand why some folders can open and others not . Has anyone any suggestions please. I have been trying to get this to work for months since iCloud drive came in. It has got much better but it is still not good enough - or maybe it's me?

All I can suggest is that you open that file on the MBA and save it as a new file, then see if you can open the new one on the iMac.

Is there a setting to prevent modification date change after adding label or changing orientation?

is there a setting to prevent modification date change after adding label or changing orientation? I don't want to change the modification date when I haven't edited the image, but only rotated the view or rated/labeled it. Is there a setting to change to not have this happen?

You have modified it, but why worry? The date shot does not change.

Setting always change when i open ms word on my pc..

why every time I make a setting with ms word for mac always change when I open it with ms word program on your pc?

Why would you expect a setting in one program on one operating system to affect the setting in another program on another operating system? I likely did not understand your issue from your description. Or do you mean for example if you create a document using red for the type color that the color changes to another color when you open the document in another installation of Word?
I suggest you ask in the Office for Mac forums. http://answers.microsoft.com/en-us/mac?auth=1

How to stop automatic date changes when opening an old document?

I use Pages to create my invoices. The problem I'm having is this: when there is a question about an invoice and I need to reopen it the date changes from the original date (which I need) to today's date. I understand why it does this, and I want it to do this when I create the thing, but is there a way to keep it from happening from saved documents?
As a follow up question: it must be very simple to find the date the document was created. Could someone please tell me where to find this?
Thanks in advance

You likely put a date stamp on your invoice via the menu hiearchy, Insert > Date & Time. Highlight the date string, then from a right-mouse button menu, choose Edit Date & Time... You will see another pop-up that gives you some control over your newly inserted Date & Time.

Quirky date changes when resizing columns

I have a new eMac, when I make the date modified and date created columns small, the date goes to 7/31/05 for all files.
When I expand the columns then the dates change to this format Nov 7, 2005 9:00pm. This happens on both the "date modified" and "date created" columns. But the some dates don't reflect the actual date of creation or modification.
I also noticed that when I download files, the modified and created dates don't reflect the actual date I downloaded them. Some items I have downloaded recently, have 2003, 2002, 2000 dates associated with them.
On my G3, all downloads would reflect the actual date download for the modified and created date. Is this not the case with the eMac?
Could it need a battery this soon?
Thank you in advance,
Deb
Update:
I just ran System Profiler and up in the top right hand corner the date says 7/31/05.

Hi JMVP, thanks for replying.
I'm running the org 8.5 on the G3 but have 9.0, 9.2 and 9.22 on my external hd's.
Yes set date automatically is checked. I tried unchecking it and nothing changed.
Timeserver is Apple America/US (time.apple.com)
My biggest concern is why are all the dates changing to 7/31/05 (style, format and using the actual date of 7/31/05) when I squeeze the column width down. But once I start expanding the columns the dates change to, what I'm assuming is the date of their creation and modification, and not the downloaded date.
This may be a stupid question, but what is a relative date, compared to, what a normal date? Every time I check or uncheck this box the dates don't change format, style or anything.
Thanks again for your help.
Deb

I have a problem when update tables with a database link (APEX)

Hi, I search answers for my problem and I not found a solution. My problem start when I open page with database link statement in APEX. I drop tables and execute this for update the tables in APEX.
EXECUTE IMMEDIATE 'CREATE TABLE XXXXXXX
AS
SELECT A1,A2,A3
FROM AAA@BBB';
I use Mozilla Firefox and isn't always updated the tables because it shows dialog for downloading file "f". I rename the file to txt and I see the text "IBMPC/WIN_NT-8.1.0"...
In the explorer always show a window only the text "IBMPC/WIN_NT-8.1.0"...
What is the solution for my problem? I need update this tables.
Thanks. John.

It's easy. It doesn't work a database link, on apex, with a pl/sql code or store procedure.
I saw that many people had the same problem but I don't see a solution.
As I put up, I want to remove my tables on APEX and copy the table of my Oracle database with the update dates.
The posts are from the same problem as my English is very bad, it got to help explain the problem.
I have a page with a pl/sql code. This code in Oracle is correctly.
For example, with this code I update the table PRUEBAS with the data of TABLEX.
BEGIN
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE "PRUEBAS"';
EXCEPTION WHEN OTHERS THEN NULL;
END;
EXECUTE IMMEDIATE 'CREATE TABLE "PRUEBAS"
AS
SELECT AAA,
BBB,
CCC
FROM TABLEX';
END;
But, in this code, I have the problem.
BEGIN
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE "PRUEBAS"';
EXCEPTION WHEN OTHERS THEN NULL;
END;
EXECUTE IMMEDIATE 'CREATE TABLE "PRUEBAS"
AS
SELECT AAA,
BBB,
CCC
FROM TABLEX@DB_LINK';
END;
I sometimes get an error. Sometimes it works fine, but half of the tries Apex returns "IBMPC/WIN_NT-8.1.0" in the browser and I am not using an IBM PC or Win NT...
And i read that In the alert_xe.log file there are a error of core dump... ... :S or that the application return corrupt headers.... Is a problem of versions?
I used a synonym and I have the same problem.
Even if I run the code on SQL COMMANDS (SQL WORKSHOP) it shows dialog for downloading file "f". I rename the file to txt and I see the text "IBMPC/WIN_NT-8.1.0"...
The problem is in Mozilla Firefox and in IE.
I have the OracleXE 10g (Application Express 3.0.1.00.08).
And the question is.. ... ... ... ... What is the solution? :)
Thanks.
John.

Numbers entered data dissapears when spreadsheet opened at a latter date

data entries entered into the spread sheet dissapear.
We have a spreadsheet setup with formulas to manage our cash flow. When we update it. Close it and come back the next day yesterday's entries have dissapeared
any thoughts as to why

Update. We feel the source of the problem is from the iCloud Windows App on my computer. We do not use the computer on a daily bases. When we shut it down it holds the current spreadsheet update. When we reboot the computer it updates iCloud with the spreadsheet and eliminates any changes made to it From our iPads.
Interesting. So maybe iCloud for Windows is overwriting other changes. That sounds plausible. If it turns out that was indeed the problem, hope you will have time to stop by and leave a brief note.

Date changing when dragging/copying photos

Help! I am trying to organize my iPhoto library. I am essentially dragging my photos from my library to a folder or dragging them to an externa hard drive so I can then organize them into a new library. The dates and times are correct in iPhoto. Then, when I drag them into a new folder the dates will completely change. I had an event with 4 photos in it and the correct date for all photos was 4/19/05. When I drag this event to a folder in my pictures file or when I drag the event into dropbox, the date on 2 photos changed to 3/17/11 and the date on the other 2 photos changed to 9/30/09. Does anyone know why this is happening or how I can stop it????

Suggested by a friend, I realize may be controversial... but, I have run out of room on my hard drive and need to dump my photos onto an external hard drive. So, here is what I am doing:
1) I create a folder in my pictures folder in Finder (Home --> Pictures --> New folder) for photos from a particular year (let's say 2008, let's say the folder is named Photos 08)
2) I drag an event/events of pictures taken in 2008 from my main iPhoto library into the folder Photos 08. This is the step in which I see the date change.
3) I switch to a different iPhoto Library (let's say Photos_2008). I have so many photos that my friend and I thought it would be easier to break them down into smaller libraries.
4) I import the photos from the folder Photos 08 into the iPhoto library Photos_2008. When I import the photos into the new library they all come through but they are lumped into one event called Photos 08 and the dates are still wrong. At this step, I have been manually correcting the dates.
5) then, I move the Photos_2008 library onto the external hard drive (actually 2 different external hard drives to be safe)
6) I make sure the photos are there by opening iPhoto from the external hard drive, and then delete (all the while cringing) the events from 2008 that are in my main iPhoto library
Does that make sense? Do you have any better ideas on how to get these onto the external hard drive? I'd like to keep some of the photos and my more recent photos on my computer but need to get the other ones off.
Also, a little background info... in early Sept '12 my system crashed. I also back everything up with Time Machine so they ended up reformatting my hard drive and then I used Time Machine to get everything back on my computer. Since then, my computer has been a mess. Multiple users with the same photos, songs, documents, etc. duplicates, triplicates of photos, documents, songs, etc. on my computer. A real mess.
Thanks for any advice you can offer,
StephPH
