MacBool Air / Leopard keep forgetting file preferences.

Hi,
My MacBook Air keeps forgetting file preferences. I'm an audio engineer, and so I want my audio files to open in the programs I prefer over iTunes. Also, quicktime can't play most AVIs, yet it tries to open them.
I know how to set the preferred programs in the info dialog. But as soon as I restart (which I do about once a week) all these settings are gone. This is particularly annoying with iTunes, as it conflicts heavily with my other software, but I can't trash it until I found a good batch convertor.
I first noticed this forgetfulness after switching on FileVault.
The question is: How can I make my macbook remember these settings?

This information is stored/controlled by Launch Services. I would try resetting the LS database and see if that helps.
Run these commands in Terminal:
cd /System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServi ces.framework/Support/
./lsregister -kill -r -domain local -domain system -domain user
Hope that helps...

Restore snow leopard without removing files/preferences

I installed Lion when it first came out but i want to go back to snow leopard to be able to use Pro tools 9 software. However, i dont want to lose some files and settings. How can i do this? i do have a time machine disk which was used atleast once with Snow leopard. Thanks

Backup first. Then,
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

Leopard keeps losing my shared printer

I have a 500 MHz TiBook running 10.4.11 that I have been using a print server and file server. My printer is connected to the TiBook by USB, and shared through the Sharing Preference Panel.
My main work computer is a MacBook Pro. When I had 10.4 installed on my MBP, it remembered the existence of the shared printer. However, since upgrading to Leopard, my MBP keeps forgetting about the shared printer. I frequently have to "Add new printer". This process takes a long time, because it insists on searching for new drivers, etc.
Does anyone know if there is something I can change in my configuration to make Leopard remember that this shared printer exists, and that it is my default printer?
Upgrading the TiBook to Leopard is not an option, because it is a 500 MHz machine.

This was fixed by the OS 10.5.2 update.

Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Safari Keeps Forgetting Settings

Safari keeps forgetting the setting after I close it down and open it up.It goes back around to the Safari Apple Welcome Page.Reinstall safari but with no joy at all.
Anyone Help

Okay ... it's likely to be trouble with settings/preferences files and so forth. So I'd be inclined to rebuild all of those. Try the instructions from the following post:

MacOS X Mountain Lion keeps forgetting wallpaper

Hi,
on my iMac (Model 2012) Mountain Lion keeps forgetting my wallpaper setting. I set it to show a random image from the default background desktop images coming with Mac OSX.
After a restart but also randomly when waking the iMac up, the desktop background is blue again. If I then check the wallpaper setting, I can see that "Random order" is still ticked. But the checkmark at "Change image daily" is gone.
Does anybody know this problem and has an idea for a fix?
Best,
René

I suspect that there's a problem with the Desktop settings file, so you must delete it. First, open Finder, select Go menu (on the menu bar) > Go to Folder, and type ~/Library/Preferences.
Then, delete "com.apple.desktop.plist" and "com.apple.systempreferences.plist", and restart. Finally, that problem shouldn't appear anymore

How to restore my intel iMac running Tiger 10.4.11 to factory default - keeping my files, must I Format HDD ?

First, I need to know how to confidently Back-up all my files to a External HDD, since Tiger does not have Time Machine.
Next, Keeping my files, I wish to restore the mac to it's original factory (out of the box) settings. The 'Home' Directory got "renamed" and messed up where everyone's files/playlists etc. were.
Was considering upgrading to a newer O/S but most say that is not recommended. ?? Any suggestions
iMac spring 2007 vintage, intel duo core 2.16 ghz? (I think?)
thanks,
JP

1. You won't lose any data, you may lose updates but these are very easily restored by simply running Software Update and following the on-screen instructions.
2. Again if you don't restore setttings their settings may be lost. In short you can't have your cake and eat it too. You originally said you want to restore the system to it's factory out of the box settings so you need to decide what to do. Frankly if it were my system I'd do a fresh install and restore everything including the settings and your system will run better and retain the settings you have tweaked over the years.
3. If the kids want to update their iPods then yes you have to get to a more current version of OS X. You're several generations behind now. Assuming you have a system that will support Lion 10.7.2 which would be:
General requirements
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Some features require an Apple ID; terms apply.
Then for $60 total which is $29 for Snow Leopard 10.6.8 and $29.99 for Lion 10.7.2. You can skip Leopard (10.5.8) which is nice. And no you cannot skip directly from Tiger to Lion. Plan on spending an evening or morning updating. Total time depending on the amount of data you have would be about 2-3 hours.
4. You can determine the IOS version on each iPod Touch by clicking Preferences - General - About and look for the version.

Saving attachments on Snow leopard mail loses file extension when saving over an existing document

Saving attachments on Snow leopard mail loses the file extension when clicking on an existing file to copy the name. Is there something I can switch on in the preferences to fix this?

I work for a publishing company where our clients send their copy to us in Word documents. We might have several versions sent to us before the final version comes in.
It is instances like this where we want to overwrite a document on the server with the most up-to-date version (which is usually named differently to the original file). We really don't want to clutter the folder with lots of different revisions. The quick way to do this is to click on the document we are replacing (this copies the document name). Previous versions of OSX Mail used to keep the file extension but Snow Leopard seems to remove it.
It's annoying as there is no particular logic to this. We just have to manually type ".doc" at the end of the document.
Incidentally, this happens with any attachment file type.

ITunes keeps forgetting location of music on external drive

iTunes keeps forgetting the location of the music i have which are stored on an external drive. it remembers a handful of them but forgets the rest so i keep getting an exclamation when i want to play them. how can i make iTunes permanently remember these files????

ah sure that's what i have been doing. the drive is always on before iTunes but iTunes can never find my music without me actually finding them for it. the location in iTunes preferences is also pointing towards the drive so not sure why it can't find them!?

How do I keep a file open and am able to look at all the pictures in the file?

I want to oepn a file with 24 picturees for example. I want to keep that file open so that I can see all 24. Then I can work on 1 picture or another. Now each time i finish with a picture and save it if I then open another pciture it overlays the other. I was able to do the above in my earlier version of photoshop.

Editor preferences>general, and turn on Allow Floating Documents. Then Window>Images>float all in windows.

How can I keep the file/ album names when copying music from the Finder to iTunes?

Hi,
Is there a possibility to keep the file names one uses in the Finder when adding music to iTunes?
[e.g. that a Beethoven symphony still ends up under 'Beethoven/ symphony No./' and not under the name of the orchestra/ dirigent]
Thanks in advance
Kath

Yes. Go into Preferences and make sure that "Keep..." and '"Copy..." are both not checked. Then put the file(s) where you want them (preferably somewhere in your iTunes Media folder) and use the command File > Add File (or Folder) to Library.
Try this first with a file or two so you can see that it keeps the same file name as it adds to your library.

In snow leopard, how make files "invisible"?

in snow leopard, how make files "invisible"?

You can make files or folders invisible from the Terminal. Enter the following command:
chflags hidden
Don't press enter yet. Put a space after the the word hidden and then drag and drop the item you want to hide into the Terminal window. Now press enter. The item will disappear from view.
You'd better copy that path down though, because if you want to unhide it, you need to know the full path and file or folder name.
As a test, I did one as:
chflags hidden /Users/myaccount/Desktop/test.tif
This of course is a file named test.tif sitting on the desktop of my user account. Upon hitting enter, it disappeared. To get it back, you unhide it:
chflags nohidden /Users/myaccount/Desktop/test.tif
The item will reappear. You can see where it would be very important to have that entire path written down. If you forget the name or where it is, you'll be lucky to find it by guessing. It's either that, or you'll have to use the trick to show hidden and system files. Then you'll be able to see the hidden item you're dragging and dropping item into Terminal to unhide it.

"Keep Both Files" is NO Substitute for "Do Not Replace"

Can someone please post a Terminal command sequence to disable the "Keep Both Files" option in the Finder copy dialog? It's useless to me and I've already wasted several hours trying to manually work around this bug and shut it off on my own. Anyone with a digicam hobby will quickly run into the huge drawbacks of the loss of this feature.
I routinely deal with thousands of individual files on a daily basis; the file names repeat very frequently and the files arrive from multiple sources, therefore these files do NOT all have unique identifiers and each batch can be hundreds of GB. They all need to be moved and backed up weekly or more frequently. On a daily basis I move between 250-500GB of files between directories and from devices to the computer, et cetera. Without this function there is literally not enough time in the day to carefully manage a production system, which equates to a waste of time, electricity, and brain power on mundane tasks. Who keeps their entire file tree on paper so they can refer during copying between directories?
Windows 7's mostly useless "Keep Both Files" feature has no place in a system as useful as Apple's. It really doesn't help with anything other than to offer a rubber bumper to protect inattentive people from overwriting files, which was elegantly in place up until Lion. Come on, you can't GUI someone's inattention out of the equation. If you could, would I be typing this?....
Listen, by removing the "Do Not Replace" option from the finder copy dialog, I am forced to either increase storage space--I can't believe I need to explain this, but I will say "unnecessarily" just to be redundant--or alternatively I must copy EVERY FILE???!!!! So, if only 50 files out of 1,800 need to be copied I still have to move all 1800 or sort through them one by one.
You have got to be joking. Give me a Terminal rip to kill this behavior please. This is an amazingly full-fleshed waste of time. It seems obvious enough that this is a programming SNAFU. "Do Not Replace" has been removed from the Finder copy dialogue because Lion actually cannot do both that and "Keep Both Files."
So, who knows the code for Terminal to revert this behavior to the pre-Lion days? Post that sucka!!!! A lot of people are looking for it.
I swear I will regress to Slow Leopard just for this one single feature-- and sorry ya'll, I doubt I will be the only person who can't spend all day waiting for drives to back up.

Okay, what we are griping about is called "recursive copying." There is a Terminal command for it.
A-and, the Terminal command is in bold if you already know how to do this. Otherwise, here's a primer for command-line interfacing. If you want to learn more about the cp command, type [ man cp ].
1. Open the Terminal application (in Utilities).
2. Type this code, which is a basic command for recursive copying ("do not replace" for us non-tech linguists):
cp -Rpn /originating file path/ /destination file path/
3. Hit return. If you're moving a large amount of data, say a few gigs or more, at this point the cursor will disappear and the file transfer will take place. The cursor reappears when the operation is done. You can do other things like normal on your computer at this point, but don't move or alter any of the files during the transfer (just like normal). While that cursor is gone there's a transfer going on. If you're curious if it's working (or distrustful like me), you can open a finder window at the destination to watch the files show up.
If you're wondering if you have to do all that typing, the answer is no. Type in the [ cp -Rpn ] exactly like that and then drag and drop folder 1 into the Terminal window. It'll give you a file path automatically. Then you only need to put a slash after it and then drop the folder you want to copy into onto the the Terminal window. You might have to type another slash. Hit enter.
Apologies to the person who posted this information on another site or here in the forums. I haven't found your post, but when I do I'll attribute. Many thanks!
