Maybe you need to keep an untouched RAW image in a separate folder that’s only use is to be copied somewhere else for editing/retouching? That way it’ll never be saved over intentionally by yourself. If it was security/permissions related, you wouldn’t be able to access/view/read/save the file etc… Apple does do weird things with metadata, and it could be an app like Adobe Bridge that tags files as it caches them for display. I don’t think this has anything to do with permissions and security, this is all metadata based changes. Nothing is working it is still being overwritten by apple.” “The file has ALL permissions and the disk has “ignore ownership” I have done multiple permission updates and repair disk. So, you may be seeing one of the new files if it’s not a mixup between modified and created. If you’re using Apple’s own tools like Photos, Apple does create multiple versions of the files if you modify the image in any way. This also sounds like your finder window us showing the modified date while spotlight is showing the created date.
The drive is overwritten by Apple to reflect an incorrect “date created” Spotlight shows the same file with the correct date.” “I can confirm this by searching for the file in Spotlight and comparing it to the file data on the drive. Sometimes folders view stuff differently to what’s specc’d by the parent. Check your finder window view preferences and see what’s showing. Most apps will add metadata to the file, so the file is updated and the newer date is shown. This sounds to me like you’re confusing the ‘created date’ stamp with a ‘last modified date’ stamp. “It changes the date of the RAW media to reflect the date of the application that last used the media or the user that duplicated the media.” Hey Russ, I think I have an idea on the trouble you’re having. To get help, you need to supply info like: what machine you are using and the OS what the drive is that you’re trying to copy to the filesystem that the drive is formatted with and what the actual problem is that you’re having! You really have not explained what your problem even IS exactly. Perhaps what you are looking at is a different date attribute. If it helps, there are four different dates that Apple keeps with a file’s metadata: file created, file modified, file added, and file last opened. I imagine you have probably messed around with permissions and gotten yourself in over your head. They use a simple, tried-and-true system for establishing ownership of a file.
Apple does not “control” your files nor do they link the files to a specific app, etc. Russ…you seem to be one of those people who just hate Apple for nonsensical reasons, or for doing things you don’t understand.

But, for those instances where it isn’t, now you know how to fix it. Most of the time, this will be set correctly. You only need to do this once for each of your data drives. Then, check “Ignore Ownership on this volume” and close the window.

However, if this is NOT checked, we need to change the setting.Ĭlick the lock and enter an administrator’s password to allow changes to this setting.
If “Ignore ownership on this volume” is checked, everything is fine. If it is closed, twirl open the Sharing and Permissions triangle and look toward the bottom. (My favorite is “Available,” which is always seems to disappear almost immediately.) This displays a wide variety of statistics about that hard disk. Type Command+I (or choose File > Get Info). This SHOULD be done for all direct-connected drives that only store data. Here’s how to turn off permissions on a hard drive or RAID.īIG NOTE: This should NOT be done for the boot disk or server volumes. However, especially for new drives, permissions get turned on by accident for a data drive, which then prevents it from working properly. NOTE: File servers, also, require permissions to keep track of which user has access to which file.ĭrives that store data don’t use permissions and ownership. (A permission allows one application to “talk” with another application.) This is what we are repairing when we use Disk Utility to “Repair Permissions.”

NOTE: This technique applies to, and works the same on, all versions of the Mac OS from 10.6 through 10.9.Īpplications, and the boot disk, require permissions and ownership to be accurate and enabled to function properly. If this setting is incorrect on a new hard drive you just installed, you’ll have problems accessing files on that drive. Fixing his problem was simple – but not obvious.
This article was suggested by Robert Bagley, who was having problems storing files on a newly-acquired hard drive.
