D drive. Is that true and do you need to install third party apps like AppCleaner?

I read in a popular tech blog that when you uninstall an app in OS X it can leave behind files that eventually can bog down your hard drive. Therefore you might opt for a third party cleaner. Is this true and if not how do you completely uninstall an app in Mountain Lion?

The uninstaller is the best thing to use. However, there are only a few locations where the app can install something that can continue to affect your Mac. Those will only be installed with an App that is installed with an installer. Apps you drag and drop to the Applications folder or those from the App Store will not install these things.
Drag and Drop or App Store apps can be dragged to the Trash or uninstalled in the App Store.
The locations are in either your own user Library or in the main "all users" Library.
The folders are LaunchAgents, LaunchDaemons, and StartupItems. Additionally, there may be something in your Login Items in your account in the Users & Groups system preference.
Very rarely, apps can install kernel extensions which are low-level modifications that will often cause problems, especially when updating your OS.
The uninstallers should get rid of anything they put in those places.
Always know how to uninstall an app before you install it.
I'm not a fan of things like AppZapper, AppCleaner, or any other uninstaller program as they merely look for things the might be related to the program and attempts to delete it. I would hope that they are designed well enough to avoid deleting system files in its hunt and destroy methodology, but I wouldn't trust them.
You don't need anything that purports to tune up, clean up, optimize, protect, perform periodic maintenance, or any other similar claim.

  • Upgraded to iTunes 9.2 and iPhone 4 -- all of my third-party apps missing

    I'm not exactly sure where the issue came from, but I somehow lost all of my apps as I upgraded to iTunes 9.2 and the iPhone 4 today. But I figured out what happened and *I have the solution*, which I'd like to share...
    This occurred on June 24, 2010 (iPhone 4 launch day). The steps I took to upgrade to iTunes 9.2 and iPhone 4 were as such:
    1) I did a full sync and backup of my iPhone 3GS with iTunes 9.1.
    2) I upgraded iTunes 9.1.x.xx to iTunes 9.2.0.61 (the first version compatible with iPhone 4).
    3) I activated my new iPhone 4 and set it up based on my 3GS's back up data.
    4) When it was done setting up the iPhone 4, I noticed that all of the native apps and their app data were intact, but I was missing all of my third-party app store apps. Note that all the apps on my 3GS were obviously still intact.
    5) I noticed that I had zero apps in the iTunes library (at the top left under "Library"). Thus, with my 3GS plugged in, I right clicked on the iPhone in iTunes under "Devices" and selected "Transfer Purchases". This transferred all of the apps on my 3GS to the iTunes library.
    6) I plugged in my iPhone 4, and noticed that on the "Apps" tab under "Devices / iPhone name", the "Sync Apps" box was unchecked. So I checked it, and it gives you a scary message saying that all of the apps in the iTunes Library (which I had just populated in step 5) will overwrite the app data on your iPhone. I didn't have any app data on my iPhone 4, so I clicked "OK". All of the apps transferred from the iTunes Library to my iPhone 4 with all of the app data (game saves, etc) intact.
    So that's my solution. I'm sure this must be happening to other people. My main piece of advice is: after upgrading to iTunes 9.2 and syncing your old phone for the last time, make sure you have apps in your App Library and "Sync Apps" is checked. If not, follow the steps above.
    This same issue also happened to my friend, but he doesn't have his old iPhone 3GS to restore the app data from. If anyone has any suggestions as to how he can save his app data, please let me know. Thanks.

    Well this won't work for me...
    I had all of my apps and music stored in iTunes, I updated to the newest 9.2 iTunes and did a 4.0 update to my iPhone 3G all the while not noticing that EVERYTHING IN iTUNES was GONE. When I got done updating my iPhone it was late so i went to bed... Next day came back to sync everything and thats when I saw it was all gone...
    http://support.apple.com/kb/HT1451
    did what the link said and NOW I have all my 6K+ MUSIC back but not ONE APP. The App's are completely gone from when you nav. to the location the link says... There isn't a mobile sync folder there...
    NOT SURE WHAT TO DO NEXT... Very Frustrated and MAD. I don't want to redownload all my apps manually. TO many to do it that way.

  • Okay, so my computer was having some problems.  I recently did a restore (the one where you set back time to an earlier date) itunes didnt work after that... i tried uninstalling it but that didnt work.  I then downloaded a third party app to...

    completely remove itunes...  i re downloaded after that and itunes is up and running (currently listening to music)  however i now have no way to sync my iphone to the pc...  i first tried using wifi sync, but the phone said the "pc was unavailble" and the sync button was greyed out.  i then plugged the iphone directly into the computer via a apple usb 30 pin connector.  Nothing.  The computer recognizes the iphone in "my computer" and i can access my photos that way.  but itunes doesnt recognize it at all.  there is currently no way for me to sync my iphone.  I have already "reset" my iphone... (holding down home button and lock button until it shuts off... and still until it shows a apple icon and then releasing after the apple icon goes away).  i then turn it back on and plug it into the computer.  itunes still doesnt find it.  what do i do?  i really dont want to unistall it again.. its a huge hassle and take forever.

    Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
    This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

  • I purchased my iMac using the same (and only) Apple ID I use to purchase apps. Third-party apps update fine, but the apps that came with my iMac (iPhoto, iMovie, etc) bring up a message saying I have to log in with the account I used to purchase them.

    I used my only Apple ID to purchase my iMac (Intel-based one).  I've never been able to update core apps that came with it.  I can update third party apps I've bought (like Coda), but when I try to update Garage Band, iPhoto, iMovie and so on, a popup message appears saying "You have updates available for other accounts" and "Log in with the account you used to purchase this app in order to update it", or similar (see screenshot above).
    The OS seems to get its updates fine - it's just the core apps from the App Store.
    I've only ever had one Apple ID, so I have no idea what to do.  I went to ask the Genius bar at my local Apple store, and they couldn't help, and insisted that I must have purchased the iMac using a different account, but I definitely didn't.  There are a few posts on non-Apple forums of this happening to other people, so it must be a rare bug.
    I'm a little concerned it may affect my ability to update from Lion to Mountian Lion.  Can anyone help?

    Have you done a Disk Repair and a Disk Permissions Repair?
    If that doesn't resolve the problem I would suggest calling customer support about this issue as it is most likely on their (Apple's) end that the problem exists.

    Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    * Don't make any changes on the Safe mode start window.
    See:
    * [[Troubleshooting extensions and themes]]
    * [[Troubleshooting plugins]]
    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    * Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

  • I have a macbook pro and aphotosmartD110 wireless printer.  I was told that if I install the printer software on my computer, it will no longer print wirelessly.  Is that true and how do I scan wirelessly without loading in the software?

    I have a macbook pro and a photosmart D110 printer.  I was told that if I load the software for the printer onto my mac that it will no longer print wierlessly.  Is that true and how can I scan wirelessly without loading the software? Also, can I just connect my mac to the printer with a cable and scan or do I need that software loaded onto the mac?  Thanks for all help!

    If you are running Lion then all drivers are distributed through Software Update. You do not need to install anything, other than to install the printer in System Preferences > Print & Scan. If you already added the printer while it was connected using USB, you might want to delete it and set it up again wirelessly to avoid confusion. Or, give them two distinct names e.g. "Photosmart D110 (USB)" and "Photosmart D110 (wireless)".
    All scanning functions are now performed using Preview, but you can also access the scanner through the same Print & Scan preference pane, or with Image Capture.
    This HP document may help explain how driver software is distributed now:

    I have a newer MacBook Pro with an AMD processor.  It is my understanding that Parallels can only be used on Mac's with Intel Processors.  Is that true and if so does anyone have recommendations about how to have a windows side to my Mac

    Then it either is a pirate clone or you are misinformed.
    Apple Computer has never used AMD processors in its products.
    However, the Graphics Processing Unit (GPU) is a Radeon unit, which is an AMD subsidiary. Parallels, VMWare, VirtualBox will all work fine with the Intel Core i7 or i5 CPU that powers the Mac, and use the AMD Radeon GPU that drives the displays.

    Sending by Dropbox where, To who, to what computer? As your does not start up.
    You need to take at least the OS disc to a work Mac computer and create DMG from the OS install disc then restore that DMG to USB thumb drive. Then you can boot the computer from that thumb drive and install the OS. That is if your hard drive is functioning correctly.
    Then you can use the App disc in the external CD/DVD drive to load up all the included Applications that come with your version of OS X.

  • I have a box that will not go away, it says,  "To open JavaApplication, you need to install a Java SE 6 runtime.  Would you like to check for and install one?  If i push not now, it keeps popping up, if I push install, it says it's not available, help.

    I have a dialogue box that will not go away and it seems to have started when I upgraded to Mt. Lion.  the box says, "To open JavaApplication, you need to install a Java 6 SE runtime.  Would you like to check for and install one?  (smaller print)  Note: Usw of this software is subject to the Software License Agreement applicable to the software you are downloading.  A list of Apple SLAs may be found here: htp://www.apple.com/legal/sla/
    Finally there are two boxes to click.  One says not now.  If I click on that the box goes away for 2 to 3 seconds and then pops back up and WILL NOT go away.  If I click on the second box, Install, it says  The software is currently unavailable.  To install a Java SE 6 runtime later, open Java Application again.
    My confusion here is that I have no idea what the java application is, When I click "okay" on that box, the original box pops us again and WILL NOT go away. CGoing to the apple lega web site was no help.  My solution so far has been to drag the dialogue box as far to the lower right and out of the way as far as I can.  Help.

    Does this happen immediately after you log in? If so, one of your login items is probably causing it.

    This was strange but has to do with how startup disk and nvram interact
    http://forums.macrumors.com/showthread.php?t=1795765
    I think your problems were solvable and not that the Sonnet card and 5,1 is not bootable, in fact the 5,1 is easier, there are more supported cards.
    I have the 1,1 where the Sonnet Pro is recommended but for data only and are not bootable because of the 32-bit EFI firmware. NOT the 4,1 and 5,1. The 2008's are problem child and have a mix of PCIe 1.1 slots, first implementation of EFI64 that also has problems. Also the 4,1 has two PCIe 2.x slots 3 and 4 that share a controller but that simply limits bandwidth.
    I would have left the TRIM support and NVRAM changes in Yosemite to a separate thread if you wanted to focus on the Sonnet Tempo Pro support in Mac Pro 2010-12 5,1s.
    Also the make of SSD can vary and they also have their own firmware as do bootable controllers along with the EFI of the Mac, all of which have to work together.  Meaning it might be that Samsung 840 va 840 EVO vs 840 Pro will all be slightly different but my experience is Samsungs work well (as do others like Crucial with the proper firmware - and there was/is an issue with the firmware of the Samsung 840 but not with booting).
    The PCIe card gets seen and treated as external and therefore 'eject' but of course you can't when it is the system boot drive.
    One thing I found last week and meant to mention:  After installing or changing PCIe cards, RESET SMC made all the difference in the world with the long boot delay. Some PCIe cards will add a few seconds, system has to search the device tree which now shows another controller with multiple devices - and sometimes NVRAM and SMC are what I will call "dirty" and need to be rebuilt and reset.

  • Uploaded new itunes upgrade and now some music can not be located. a screen appears and says you need to locate the songs in other folders. Any ideas? New upgrade sinks

    Hello
    just did the the new upgrade and now half of my songs are not playing. A screen appears and says you need to search for your music in folders. What the heck happen with this ? Anybody have any issues too?

    This happens if the file is no longer where iTunes expects to find it. Possible causes are that you or some third party tool has moved, renamed or deleted the file, or that the drive it lives on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout,or vice-versa, and so is looking in slightly the wrong place.
    Select a track with an exclamation mark, use Ctrl-I to get info, then cancel when asked to try to locate the track. Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, or a drive letter has changed, it should be possible to reverse the actions.
    Alternatively, as long as you can find a location holding the missing files, then you should be able to use my FindTracks script to reconnect them to iTunes .

    how can i save me data stored on a non responding ipod classic and says you need to format before using it?
    in another way : how can i save my date stored on my classic iPOD as a external hard .... when that msgs appears .... volume doesn't contain a recognized file system , make sure the file system is loaded .... then , you need to format ??? can anyone help ?

    It sounds like the iPod's storage has data corruption.  You may be able to treat it like an external drive and use data recovery software on it, but it probably won't work because the system is telling you that the drive needs to be formatted before it is recognized.
    If the problem is data corruption and there is no hardware-related problem on the iPod's hard drive, a Restore should fix the problem.  But this will obviously erase the iPod's hard drive.
