Do i need to keep DMG's on my harddrive

do i need to keep DMG's on my i mac hard drive? consequence's of deleting?

You don't need to keep them. It's often the way application installers are provided, so once you run them and are happy the app is working as expected you can delete them.

  • Do I need to keep the .dmg after installing an application ?

    I drag the dmg to the application folder and do the install, do I need to keep the .dmg afterward? as i`m doubling up on files and filesize,

    No, unless you're running the application straight off the dmg.

  • OK, Newbie to Mac question.  Do I need to keep files after download/update

    Sorry for such a boring newbie question.
    (My last Mac was many years ago - the original Macintosh 528k with 2x 3.5" disks. The OS has changed 'a little', and doesn't have to be loaded in every startup!! Wow !!)
    I had to go PC for business reasons, but now, I have <control> over my computing needs again. (Photographic business.)
    OK. I searched Mac 101 but didn't find an answer.
    Apart from Application Icons and/or Folders I have created, I have acquired a bunch of other files on the desktop. Do I need to keep them?
    When I download updates, for example, I end up with a .dmg icons showing the HD in the center, with a title such as i1Match3-2.6Pantone.dmg (after updating my calibrator). I know the update is installed (and the app. is in the dock). Same with downloads or updates with Lightzone,, Firefox, etc.
    First Question. Can I trash those .dmg icons?
    Similarly, I have icons with what looks like an external HD, which I guess is the actual download. For example, RapidWeaver 3.5.1 (no extension), but there is also a .dmg icon. These "HD" icons cannot be dragged into a General Folder on the Desktop.
    Second Question. If I can trash the .dmg icond, can I trash the "external HD" look icons once the program is installed. If I can't, where should they be kept ... I don't want them all over the Desktop ??
    Third Question. I have some Folders which just materialized over a few days of use.
    "Apples Caches" Folder (with arrow=shortcut?) with 10 file icons and 1 folder icon. Another ... "com.apple.kernelcaches" Folder with one 'kernelcache" file icon.
    And three empty Folders "Edits", Measurement Data", and "Scan Tiffs". Have no idea why they popped up.
    What to do?
    Thank you for reading my questions. I look forward to your proposed solutions.

    Al:
    Thanks for the quick reply ! The .dmg's and the "HD" icons are now GONE. I am curious why they are needed after installions, but I will read up on that to satisfy my curiousity.
    Now, the remaining question ...
    The two 'Apple caches' folders appeared on my desktop, just below the Macintosh HD icon, probably about a week or so after I got my Mac. I can't recall doing anything 'bad' or having any 'crash' or freeze-up. I seem to recall having to do a 'force quit' at one stage when I was setting up the scanner and Silverfast6Ai because I initially tried to instal non-Intel software. But on that occasion, everything fired right back up OK and the Mac has been absolutely brilliant ever since. What a wonderful change after XP and IE7 and all the daily drama.
    The Folder which has the small black arrow (I guess shortcut) has files for:
    com.apple.IntlDataCache.le
    com.apple.IntlDataCache.kbdx
    com.apple.IntlDataCache.le.tecx
    com.apple.IntlDataCache.tecx
    com.apple.IntlDataCache.sbdl
    com.apple.IntlDataCache.le.sbdl
    com.apple.IntlDataCache.le.kbdx
    com.apple.IntlDataCache
    com.apple.Components2.SystemCache.QuickTimeComponents
    com.apple.Components2.SystemCache.Components
    plus it also contains a Folder:
    com.apple.kernelcaches ... which has
    kernelcache.ED112BB5 as the file.
    Does this help you? I don't know if they have to be "put back" somewhere, or they are temporary files which can be trashed.
    (As for the other empty folders "Edits" etc, my guess is they somehow arrived during a scan which I cancelled halfway through, or maybe from the Rapidweaver application when I was 'testdriving' the program. I am inclined to trash them anyway. Can't see how that would hurt.)
    I reported that the question had been answered, anyway, but I would like MORE of the same !!
    Cheers

  • Do I need to keep my external hard drive connected at all times for time capsule?

    Do I need to keep my external hard drive connected at all times for time capsule?

    Hi,
    I have a similar question. I have backed up my external hard drive through my computer, onto my TC. When I go into TM, it doesn't show the external hard drive unless it is connected to the computer. Can I access the info from the external hard drive that is on the TC if I don't have the hard drive plugged in? If so, how can I do that?
    Thanks,
    Bernadette

  • How do I change to a new Apple ID on iPhone4 (need to keep old ID usable aswell)

    How do I change my Apple iPhone4 - Apple ID from the ID it is set up with, to a new one.  I need to keep the current Apple ID as it is used by another family member on their iPhone.  At present both phones are using the same Apple ID.....

    You can create a new Apple ID here

  • Once I finish an iMovie project and I publish it to various destinations (Dropbox iTunes YouTube etc) do I need to keep the original raw video on my MacBook or can I archive it to an external hard drive.

    I have now finished 3 iMovie projects and have learned how to prepare them for sharing through various media like Dropbox, iDVD YouTube iTunes etc. but I now have produced a huge number of related files which are filling up my hard drive to the point that I can't import any further raw video until I archive or delete many of these files.
    What files do I need to keep on my MacBook in order to be able to keep these various shared locations functioning, and what should I delete or archive?

    iMovie works best with uncompressed audio. If your track is MP3 or AAC, you may get better results by converting your track to the AIFF format and then using that in iMovie.
    You can do this in iTunes. Go to iTunes/Preferences and click the General button. On the General page, click the Import Settings button. Choose IMPORT USING: AIFF ENCODER.
    (note: remember what you changed it from so you can change it back later, before you import another CD)
    Now, in iTunes, select your track. Then click FILE/CREATE NEW VERSION/AIFF VERSION.

  • Need to do a re-format, what do i need to keep?

    hi, I need to re-format my desk top computer and re-install my OS. I've got a big i-tunes library and have spent ages organising it and importing artwork so don't want to lose anything. All my music is stored on an external drive so won't be touched by the re-install.
    What I want to know is what files do I need to keep in order for my I-tunes to operate in the same way after the OS re-install?
    I presumed it would be the files in my c drive-> programme files -> I-tunes folder so did a dummy run by transfering these files to my laptop, and connecting my external drive and mapping it to the same letter. It didn't work.
    Have I missed some files?

    Copy the entire _*iTunes folder*_ in My Documents/My Music to the external.
    Then copy it back after you fromat.
    You can even keep it on the external and use it.
    Click the icon to launch iTunes then immediately press and hold Shift.
    iTunes will ask if you want to *Create new library* or *Use existing library*.
    Select *Use exisiting library* and select the *iTunes library.itl* file in the *iTunes folder* you copied to the external.

  • Do I need to keep a local copy?

    All of my music is on a single external drive.
    Once itunes match upoads/match all of my music, do I need to keep the external drive connected to one of my computer?
    Can I store the external drive in my safe or even trow it out and keep everything on the cloud without any local storage?
    Thank You

    Thank you for your response. However I am still puzzled about having to keep a local copy. To be safe, this mean that I also have to keep a backup of my local copy as well.
    If you care about your data, yes you should. Redundant backup plans are what keeps data safe.

    ITune Match has a copy my entire song collection as both links to my songs known to the Apple Store and cloud copies of my songs it could not match. So effectively iTunes Match has my entire 10,000 song collection but I am still forced to keep a backup of my song collection in a safe or on another cloud service like Dropbox or I risk loosing it all when my local drive eventually fails!
    It's not a true copy. Think if it as a mirror. For example I purchased the recently remastered early Rush albums on CD. There was one album in each box in 24-bit, 96 kHz which I have ripped and then converted to AAC @ 256 Kbps for the highest quality AAC track I can get. Now, most of these tracks were matched to tracks in the iTunes Store (which is fine since I'm going to be listening to them on my iPhone), but they are not the same tracks that are in my iTunes library. If I had a disaster I would not be able to restore the tracks I spent to much time on, I'd have to settle for the tracks I can get from the iTunes Store. For me this is not an optimal solution, which is why I keep local backups.
    If none of this is important to you, or if your other personal data is not important to you, then by all means don't backup. The choice is yours. But if you do not backup you will eventually lose data.

  • Backing up files on external hard drive... do I need to keep render files?

    Hi, I back up all of my video work and files onto DVDs and to a Lacie external hard drive. I am filling that up quickly and would like to know if I need to keep copies of the render files, which are quite large. Will it save me that much time later? Or are they simply taking up much needed space?
    thanks in advance
    Rob Grossman

    Welcome to the forum!
    Render files can always be regenerated if needed. I dump them before backups.
    If you keep your original footage on tape, the only stuff you need to back up is the FCP project file, any still images, AE files, etc. This takes VERY little space in the scheme of things.
    The final quicktime video file (if that is what was created) can also be sent back to tape.
    Good luck.

  • Do I need to keep the Capsule plugged in to my cable modem in order to use it for backup?

    The location of my cable modem is really inconvenient. I'd like to move the Capsule to a different room. Do I need to keep it connected to the cable modem in order to be able to use it as my Time Machine backup device?

    I assume your cable modem is a router.. as such the TC should be wired to it in bridge. It will not do anything worse than now for the network in the house.. and the TC can then be accessed as per normal.
    TC is designed to be plugged into the modem or main router by ethernet.
    You can move it anywhere you like in the house as long as you have ethernet connection back to the modem.
    You can run the TC by wireless .. it will have the following effects.
    1. Super slow backups. It will simply reduce the current wireless speed by half or more for backups.
    2. Since there is no QoS your internet will stop during backups. Or near to.
    3. You will affect all wireless clients during the backups.
    It can work, if your backups are very small.. but the TC becomes a near to useless dumb client in the network.. ethernet ports are off, wireless becomes mere client.. so you cannot even connect directly to it.
    If you try the TC in stand alone.. ie a secondary network.. that can work.
    1. The computer will then have backups or internet not both. You will need to deliberately connect to the TC to get backups working. That is assuming you use wireless.
    2. You can do it with ethernet. and have internet by wireless. but the setup is tricky.. tell us if you want to proceed this way.
    3. The problem is, the TC now becomes useless to the whole network and is only used by one computer. You may as well have bought a cheap USB drive, which is more reliable and faster.

  • Do I need to keep my original photos after iPhoto imported them?

    I am new to Mac so I am not sure how iPhoto handles the photos that have been imported. I assumed it was like iTunes, however I see that my iPhoto Library file is about 20 gigs, which is about the same size of all my photos.
    Did it duplicate my photos and put them in the iPhoto Library?
    Do I need to keep the originals?
    This just seems a little odd to me if it duplicated all my files. I am now using 40 gigs of space instead of 20.
    The reason for my question is I am trying to setup a second user and share the photos on each account. iTunes was no problem, just put it in the shared folder and pointed each user settings to it, but everything I read about iPhoto sharing makes it sound a lot more difficult.

    What are the advantages / disadvantages to running a managed library or not?
    You really, really want to use a Managed Library.
    1. Importing and deleting pics are more complex procedures. You have to to put the files where they will be stored before importing them. When you delete them you'll need to remove the files from the HD yourself.
    2. You cannot move or rename the files on your system or iPhoto will lose track of them on systems prior to 10.5 and iPhoto 08. Even with the later versions issues can still arise if you move the referenced files to new volumes or between volumes.
    3. Most importantly, migrating to a new disk or computer can be much more complex.
    4. Because iPhoto has no tools for managing Referenced Files, if, for some reason, the path to the photos changes then you could find yourself resolving aliases for +each photo in the Library+ one by one.
    My own opinion:
    I've yet to see a good reason to run iPhoto in referenced mode unless you're using two photo organisers

  • Can I lock a contact so I can't accidentally call it?  I need to keep them unblocked to track calls/texts from them...

    Can I lock a contact so I can't accidentally call it?  I need to keep them unblocked to document their calls/texts so I can't delete them.

    Yes. AIFF performs no compression so your copy will be bit for bit identical: no loss. It uses a lot of disk space too. Apple Lossless (ALAC) will compress, but also with no loss. Expect file sizes about 50% of the original.
    The sample rate of 44.1 KHz is identical to that of every commercially produced audio CDs that I am aware of. There is no benefit in increasing it or attempting to "tweak" its settings.
    I used Toast for many years and consider it a well designed product. I have not had any reason to upgrade to more recent versions though. If you copy the CD audio with no loss (AIFF or ALAC), then that obviates any question about sound quality since it will be identical to the original. Toast may be able to alter the sound quality but I don't advocate trying to improve upon what is essentially your only "master" - the audio CD. As I recall Toast had features such as noise reduction. That may be valuable for magnetic tape, but it's not a concern with a CD. Even very good noise reduction alters the original to some extent, and it seems to me that you want an exact duplicate. Any alteration will be contrary to your stated goal of bit-for-bit reproduction.
    Don't know about Amadeus Pro.
