Can You Delete .dmg Files After Installing
A dmg is a disk image. I think of them as a disk within a disk. If it won't mount it's possible the file is corrupted, or incomplete. Also I think there is a way to not automatically verify dmg files, which will sometimes let you mount dmg's with 'weird behaviors'.
- A DMG is like a ZIP file, but it mounts a virtual drive on your desktop for installation. You must 'eject' (or unmount) the virtual drive, then you can delete the DMG file from your computer. If the DMG has a virtual drive mounted, then you cannot delete it because it is still open.
- How to Use Automator in Mac to Eject and Delete DMG Files Automatically. On Macs, you need mount a disk image and then unmount it and delete once the installation is finished, which can be a.
DMG files are like CD's but virtual. They simply contain the data to be transferred to your hard drive. Just like software 10 years ago keeps working when you break the installer CD, you can safely delete these DMG files after installing.
I could be wrong about that one though.Macs 'don't do' executable files. One reason it's harder to make viruses for mac os.As of 10.3, the OS can zip and unzip zip files, but the standard archive that you may see for the mac is.sit, which is a stuffit archive.There's also gzip and tar, but I don't really know much 'bout those.sit and.zip files are compressed archives which can be expanded.Product Installed.pkg (package) is kinda like the equivalent of a 'setup.exe'. It's a program that's an installer.img or.dmg is a virtual 'disk image.' Double click it, and you should get a virtual disk on your desktop. Copy the program from the virtual disk to your hard disk applications folder, and you're set. You can then 'eject' the virtual disk.Agreed.
Sounds like your.dmg didn't download correctly. Corrupted, most likely.Welcome to the Mac. I'm not sure if you ever seen. The page for the VLC download (with alternate download sites) is.Plus, OS X is based on BSD which is a form of Unix. So I little preventive maintenance can go a long way!
IMHO after most every major software install (even from Apple) a person should go to Applications-Utilities-Disk Utility and run Repair Permissions. Unix uses all kinds of Permissions for files and a lot of software developers still haven't figured then all out yet. So running Disk Utility and Repairing Permissions will save many future software headaches.One more thing, you can always do a Get Info on a file by highlighting a file and select File-Get Info or do a commandthe Apple button+i (the same output). Then a small window opens. Inside that window is an 'Open With' and you can choose which program open the file. The one mine is set at is DiskImageMounter and.dmg files all open good.
Maybe you should check to see what the file is set to open with. That would be a good start.
If you’re switching to macOS from Windows, you might be confused about installing software. Sure, there’s the Mac App Store, but not everything is in there.If you look for apps outside the store, you’ll find different kinds of installers: DMG files with apps in them, PKG installers, and simple applications inside ZIP archives. It can seem overwhelming, but it’s relatively straightforward once you get the hang of it. Here’s how to install software on your Mac, from the App Store and beyond, and why all these different methods exist. Mac App Store: Click a Button to Install an AppWe’re all used to app stores on our phones, but on the desktop they remain an oddity. Still, the Mac App Store is a decent first place to check.
Open the store, search for the app you want, and click “Get” then “Download.”Your application will download and show up in your “Applications” folder. Updates are all handled by the store, which is convenient, and any application you purchase on one Mac will work on another. There are all kinds of upsides here.RELATED:Still, you probably won’t install all of your software this way, because the App Store. There are several reasons for this. First: apps from the Store are, but limits what applications can do. Pretty much any application that customizes macOS can’t run in a sandbox, which is why you’ll have to look elsewhere for tools like Dropbox, which by definition need to work outside the sandbox in order to function properly.There’s also the matter of money. Apple gets a cut of all sales in the Mac App Store, and companies like Microsoft and Adobe don’t like that, which is why Microsoft Office and Adobe Creative Suite won’t be in the Store anytime soon.

Even some smaller companies avoid the Mac App Store for this reason.We could go on, but needless to say not everything you want will be in the App Store. DMGs and Other Archives: Just Drag and DropMost macOS applications downloaded from outside the store come inside a DMG file. Double-click the DMG file to open it, and you’ll see a Finder window. Often these will include the application itself, some form of arrow, and a shortcut to the Applications folder.Simply drag the application’s icon to your Applications folder and you’re done: the software is now installed. It’s so simple it confuses some people—surely there must be more to it than that? There isn’t: dragging the application to your Applications folder is the entire process.You don’t have to put your programs in the Applications folder, though: they’ll run from anywhere.
Some people create a “Games” directory, to keep games separate from other applications. But Applications is the most convenient place to put things, so we suggest you just put everything there.DMG files are mounted by your system, like a sort of virtual hard drive. When you’re done installing the application, it’s a good idea to unmount the DMG in Finder when you’re done installing: just click the “Eject” arrow.Then you can feel free to delete the original DMG file: you don’t need it anymore. Other Archive Files, and Loose Application IconsOccasionally, applications will come in ZIP, RAR, or 7Zip archives instead of the standard DMG. In these cases, you need to open the archive.ZIP files open fine out of the box, but you’ll need something like in order to. Once you open the archive, you’ll see the Application icon appear in the same folder.Simply drag this icon to your Applications folder and you’re done.Some applications don’t come in any sort of archive at all; instead, you’ll download the application file directly. In these cases, simply drag the icon to Applications in order to install it.
PKG Installers: Installation Wizards Like On WindowsEvery once and a while you’ll come across a PKG file. Sometimes this will be inside a DMG; sometimes you will download it directly. In all cases, you need to double-click the PKG file to run it instead of dragging it somewhere. You’ll see an interface not that different from Windows installation wizards.These sorts of installers can do things the drag and drop installers can’t do, like installing system services and putting files elsewhere on the computer. When you’re done installing the app, you can delete the PKG file and any DMG file it came in (after ejecting it, of course).
