Returning to Last Playlist After Restart?

Whenever I start my Touch, I'd like to return back to the last Playlist I was playing when I last played tunes from the Touch. For instance, whenever I start the Touch and choose Music, the first item that pops up is Podcasts. I rarely choose Podcasts and the last time I did, I was just showing a friend which Podcasts I had. I think I turned off the Touch without playing any Podcast but now, when I start it up and choose Music, up pops Podcasts.
What is the method used to return to my last played Playlist?
(My usual method was I'd be playing a tune, and go through the Shutdown process. And then when I would restart/start the Touch, I would choose Music, I'd see the Playlist that contained the last song I was playing)

Instead of shutting down your Touch while it's playing a song from a particular playlist, exit out to the Home Screen, then shut down. When you restart, and click on the Music icon from the Home Screen, you will be returned to your last played playlist.

Return to last position after record?

I have a key command ("return") set to return to last position. The problem is, when I record a take, this function returns me to the beginning of the recorded clip instead of where I actually started from. If i don't record anything, this works fine. How do I get around this? Thanks,

I think the last position is the punch in point. It's a separate locator event from where the place you manually started. So..therefore it takes priority.
best,

To all Mac,
Just wondering if everybody having the same issue as me?

It happend to me under Keyboard and Language & Text Preference Only
Is getting quite irritating now.

On my other MacBook with FileVault Turn Off it does not have the above issues.
Currently Running on Mac OS X Montain Lion 10.8.4

I was logged in with a temporary profile on my pc, after restarting everything seemed to be fine. But my iTunes music is all in the cloud now, and my playlists are gone. What do I do?

I was logged in with a temporary profile on my pc, after restarting everything seemed to be fine. But my iTunes music is all in the cloud now, and my playlists are gone. What do I do?
My iTunes media folder shows ALL of my music still there (including all from imported CD's), but on my iTunes, it says most of it is in the cloud? As well as my playlists that I have had for YEARS, are all gone. I just recently got a new laptop and had my iTunes transferred over, when I re-downloaded iTunes onto it, everything popped up perfectly from this same file. Now after this "Temporary Profile" mishap, nothing is working properly with iTunes.
Help! Please.

Do this. If all the synced media like apps and music are alread in the the iTnunes library just backup the iPod and restore from that backup

When ever I customize the toolbar the open new tab sign that is the + sign near the lastly opened tab in the tab bar disappears and it remains so even after restarting Firefox.

When ever I customize the toolbar, the open new tab sign that is the + sign near the lastly opened tab in the tab bar disappears and it remains so even after restarting Firefox. This happens only after updating to the new version 4.0.1 it never happened in the older versions 3.x.xx- checked it thrice. Thought it could be a bug and i didn't know where to report also don't have time and patience to search for the appropriate page so i'm reporting here for improving my favorite browser.

You can find the New Tab button showing as a '+' on the Tab bar. 
You can open the Customize window and drag the New Tab button from the Tab bar on another toolbar and it will become a regular toolbar button like the New Tab button that you have in Firefox 3 versions. 
If you want the New Tab button at the far right end of the Tab bar then place a flexible to the left of it.

How do I stop safari from reopening previous sessions even after restart?

Finally made the leap to Lion.
WHY does safari insist on starting up and restoring the previous session, all tabs and everything even after a restart. I've looked in preferences and for the life of me cannot find how/where to turn this off. I just want Safari to start with a blank page, not reloading the previous page/tabs I had open the last time I used it!

Thanks QuickTimeKirk for the solution to this - have hated this feature as the default. It is useful if you want to return to something specific, but I reckon the majority of users would rather have the defaults the other way around - homepage as default for new Safari sessions and using the shift key when opening to return to last viewed pages/tabs.

My Finder / User preferences never saved after Restart. Help!

After a "successful" back-up from Time Machine (thanks, Time Machine), my files seem to all be here, but my Finder and basic Application preferences have never been the same since.
My MacBook Pro 17" hard drive crashed. I had an authorized Apple repair replace it with a new drive. I restored my set-up via Time Machine as instructed and was happy to see I was (mostly) back in good shape.
What HASN'T been the same since - when I RESTART:
- Whenever I shut down/restart, my desktop will always revert back to the last "mode" pre-crash. For example, one same folder is always open, as it happened to be the folder opened during the crash. Now, no matter what I seem to have opened on my desktop before I shut down, that other "old" folder always greets me after a restart.
- Many applications I notice do not "remember" the last settings changed/used, always reverting to the "pre-crash" setting. Notable examples:
- iChat settings (buddy icon, status, etc.) must ALWAYS be manually adjusted when I open iChat now.
- iTunes and iPhoto are a big drag to open, because I must always "find" my libraries. They have long been moved to an external drive, but these iApps always ask me to locate them or create new ones. Even if I attempt to change my preferences.
- Dock: the settings/icons revert back to the "pre-crash" version, and since I have updated many Apps, several icons show the Question Mark symbol, as some old Apps are long gone.
I tried Disk Utility, repairing permissions. It recognized many inconsistencies and problems,
but the repairs never seem to "stick."
Again, this happens each time I restart/reboot.
So if I only put my MacBook to sleep mode, it does fine when it wakes up,
and remembers desktop settings, iChat settings, etc.
Therefore, I only rarely shut down now, to avoid my Groundhog's Day syndrome.
This is annoying. Help Me. Someone. Please.

Apparently the previous preferences were copied over by TM.
First it would probably be a good idea to start up from the install disk and run Disk Utilities’ Repair Disk. If you don’t know how to do that, reply back for specific directions.

Now, no matter what I seem to have opened on my desktop before I shut down, that other "old" folder always greets me after a restart.
Because it appears to be preference files that cause the problem, you can begin removing them from the Preferences folder. These .plist files can be moved to the Desktop and the system will recreate new ones in the Preferences folder. If removing the .plist file doesn’t help, the one on the desktop can be moved back into the Preferences folder to replace the newly created one.
Locate the Preference folder by this path:
Macintosh HD/Users/yourusername/Library/Preferences
(where “yourusername” is the short name of your computer, like hawaii - the folder looks like a house/home)
Often users confuse the above path with Macintosh HD/Library/Preferences. That is not the one needed. The correct one is the Preference folder in the Users home folder.
The same folder appearing after restarting is related to the Finder, so move the file named com.apple.finder.plist to the Desktop and restart. If that helps preventing the same folder appearing, you will need to reset all your Finder preferences. If not, you can return the old .plist file from the Desktop back to the Preferences folder and will need to look for another solution.
- Many applications I notice do not "remember" the last settings changed/used, always reverting to the "pre-crash" setting. Notable examples:

- Dock: the settings/icons revert back to the "pre-crash" version, and since I have updated many Apps, several icons show the Question Mark symbol, as some old Apps are long gone.
Each of the above has its own .plist file(s) in the above named Preferences folder.
It’s probably best to quit the applications before removing the preferences. Try moving the main .plist files, i.e., com.apple.iChat.plist to the desktop and restart iChat. If it doesn’t help, remove the other .plist files related to iChat. They will be replaced by the system. Some newly created .plist files don’t function until after a restart (like the Finder one described above). I don’t think iChat, iTunes, etc., require a restart, but it couldn’t hurt. If this helped with iChat, do the same procedure for iTunes, Dock, and any others giving you problems.
If these do not help, you may need to consider an Archive & Install.
I tried Disk Utility, repairing permissions. It recognized many inconsistencies and problems,
but the repairs never seem to "stick."
As long as the permissions inconsistencies include “Permissions differ,” SUID or ACL warnings, you can probably safely ignore them. But there is a .plist file for DiskUtility as well, which you may want to replace by moving it to the Desktop and restarting. If at the end of Repair Permissions it says “Permission Repair Complete,” it’s probably okay.
Again, this happens each time I restart/reboot.

How to keep the select arrow on the same button when returning to the menue after finished feature?

Hello,
just after my primary question is answered and I corrected my buttons there's another one which I cannot answer myself:
I'm putting together a DVD with menues which contain a lot of options/buttons. People who watched the DVD wanted that the select/highlight arrow stays/returns to the button they selected prior. That's because there are so many buttons/options that some people might not remember which feature they just watched. So this means if people select the "Vacation 2008" button/feature the select/highlight arrow should be on the same button after the feature is finished and it returns to the menue.
Since I haven't seen any functions/options for this: Is it possible to do or isn't it or does it happen just naturally?
Hope this isn't too confusing :-)
Help is appreciated!
Thank you,
Chris...

Where would I select "Last Menu" for this to happen? In the properties for the button or for the timeline? And where exactly: "overwrite" or "remote menu" selection?
Not in any override. Don't set any overrides unless you understand exactly how they work, or they will royally mess up your disc navigation.
Normally, you select "Return to Last Menu" for an end action of the object (timeline, slideshow, playlist, etc.) that is playing. You can also set the Menu Remote property for the timeline/slideshow to "Return to Last Menu".

IChat windows loose data after restart

Hello,
If one keeps a series of ichats open and shuts down ichat and restarts the computer, after restarting ichat the windows are still open but know have a question bubble with the name of the person previously ichated with.
using 10.6
under a previous version (10.5?), after a restart the windows reopened but with the ichats still showing. How do we get back this behavior?

Hi,
In iChat 4 you had "Remember Open Chats across Launch" which displayed the last chats you had.
In IChat 5 you have a different setting linked to Save Transcripts.
Save Transcripts has to be On.
You can then set to Display a certain number of Chats.
This does not replicate the Remember Open Chats.
Last Chat when a Buddy is also clicked in the Buddy List will display the last chat you had with them.
The Last 25 Chats option (as with other of the numbers) will display the last chosen number of IMs from that chat (Or the last chat of another selected Buddy)
(Returning to Last Chat then only displays the Last IM).
Now as iChat 5 is a new version the .plist is rewritten the first time.
This has a direct effect on the Last Chat options.
The .plist is now missing some info about the Last Chats although it can search and display the Last Chat with a Buddy if a Buddy is clicked.
It seems to get better as time goes on about displaying Open chats on Quit like the previous version if left at Show Last Chat rather than one of the numbered choices.
Another way to explain it.
In the File Menu of iChat you have Recent Items.
This lists the last Text Chats and Video or Audio chats you had and Saved Chats
(The Number of items displayed here is set in System Preferences > Appearance > Number of Documents)
It seems that there is a correlation between th Recent Items and the Saved Chats and the Last Chat has to be in both to replicate the "Remember Open Chats across Launch"
It is not a perfect match for the previous setting.
It does seem to improve.
Having said that I played and tweaked mine running though all the option I could think off and then left it for a while.
Now mine seems to remember the Last Open Chat properly. (I may have beaten it in to submission)

Desktop Icons Change Positions After Restart

Hi,
After I inadvertently synced my computer with another Mac computer my icons change position after restart. I was trying to sync another computer to mine.
I have tried the usual suggestions of taking out com.apple.finder.plist and com.apple.desktop.plist and letting the system create these new files but the problem still persists. I also checked the Finder > View > Show View Options and arrange by none is still selected.
Does anyone have a suggestion how I can fix this problem? Will I have to go back in time with Time Machine and restore my entire system to solve this?
I can't operate with the desktop icons changing positions like this.
Thanks,
Pacecom

Delete the hidden .DS_Store file associated with your Desktop folder. Launch the Terminal.app (in /Applications/Utilities/), copy & paste the following command into the window that pops up, hit the return key, quit the Terminal.app, OPTION-click and hold the Dock's Finder icon, and select Relaunch:
*rm ~/Desktop/".DS_Store"*
Now, set the Desktop as desired, log out and back in, and the Desktop should be as it was as you last set it.

Startup issues after restart

Hello,
Since updating to 10.6.7 (probably) I am having strange issues with my Mac Pro 2008 Nehalem.
The issue is that after a restart (from menu) the system always freezes on a login screen. Sometimes the screen is totally blue, sometimes it freezes in the middle of login screen appearing, sometimes right after it appeared, but freezes always.
This happens ALWAYS after restart
This happens NEVER after i kill the computer holding power down for a few secs.
Any guides for troubleshooting?
Thanks

You might try this:
You will need to type some Unix commands. If you are not comfortable with this, I don't know of anything other than a re-install. But if you are careful, you should be OK. I recommend you print this out in a largish mono-spaced font so you don't miss any spaces (or add extra ones). Note that case is important.
Be careful. Some of these commands are dangerous, since you are going to be root.
Start up in Single-User mode by restarting the computer. After the chime press and hold down the COMMAND-S keys until you see white text on a black background. When this has finished you will see a prompt ending in '#', although there may be other messages. Enter the following commands after the prompt:
/sbin/fsck -fy
Press RETURN. Wait a few seconds for 8-10 lines of output. If the last line says repairs were carried out, repeat this command until you get a message 'The volume <yourdiskname> appears to be OK'. Then continue with:
/sbin/mount -uw /
cd /Library/Preferences
rm com.apple.loginwindow.plist
rm com.apple.windowserver.plist
cd /Library/Caches
rm -r *
cd /System/Library
rm Extensions.kextcache
cd /System/Library/Caches
rm -r *
reboot
Press RETURN after each command.
This should now take you to a proper login screen after the normal boot sequence. You should then Repair Permissions by using Disk Utility (in your /Applications/Utilities folder). If you don't find all of the listed items then ignore them. They don't exist in all OS versions.

Time Machine backups only work after restart

Backup completed successfully.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
The test works on OS X 10.7 ("Lion") and later. I don't recommend running it on older versions of OS X. It will do no harm, but it won't do much good either.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message. See, for example, this discussion.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
You may have started up in "safe" mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. If you don't know the password, or if you prefer not to enter it, just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, a series of lines will appear in the Terminal window like this:
[Process started]
 Part 1 of 8 done at … sec
 Part 8 of 8 done at … sec
 The test results are on the Clipboard.
 Please close this window.
[Process completed]
The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it and go to the next step. You'll have incomplete results, but still something.
12. When the test is complete, or if you stopped it because it was taking too long, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak for themselves, not for me. The test itself is harmless, but whatever else you're told to do may not be. For others who choose to run it, I don't recommend that you post the test results on this website unless I asked you to.

My 2009 iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple log

My late 2009 27" iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple logo again. This could possibly be an HD failure, but then why does Safe Mode still work and the USB install not work? Any ideas?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
