I downloaded v.5.2.2 (Fresh) (Mac version) but am getting an error message when trying to open the DMG file.

I seem to meet the system requirements (running OS X 10.9.5 / Mavericks w- plenty of memory), so is there any recommended troubleshooting for this, other than deleting the current DMG file and trying again?

Error message displayed when I dbl-click the DMG icon/filename:

Thanks.

When you can’t open the DMG file using ordinary means, another option is to use Disk Utility to open it and save the contents using a different format. To do this, follow the steps below: Open Disk Utility by going to Finder Go Utilities. Click on the DMG file you want to open from the list of drives on the left. Follow these steps to open a.dmg file with 7-Zip: Download and install 7-Zip or an alternative extractor. Right-click the DMG file in Windows Explorer and select Extract. Extract the file to a safe location and wait for it to complete.

Comments

What error ? Try to check the hash of the file, preferably the SHA256 one, never trust MD5 if you can help it.

Either failed compilation or failed download with such error.

I'm sorry but I lack the technical knowledge to understand the two comments above.

Re: 'What error?' -- the error was the one shown in the grey box above ('The following disk images… etc.')

1) Download http://download.documentfoundation.or... to same folder as the DMG.;; 2) Open the terminal/console and enter the folder. You can do it easily by writing §cd § and drag-dropping the folder to the terminal and hit Enter.;; 3) Write §shasum -a 256 -c LibreOffice_5.2.2_MacOS_x86-64.dmg.sha256§ and hit Enter.

CONTINUED: If it says it's a match, that file wasn't correctly made and I think a bug report needs to be made. If it's a mismatch, try re-downloading.

Thanks. By 'Download' (first paragraph above) I'm not sure what you mean. Clicking on that link just displays a text string. Do you mean save the string as a text file? Or were you referring to downloading LibreOffice 5.2.2 (which I've already done, though in a zipfile I can't unzip)?

Also, in your last paragraph ('CONTINUED: etc.') did you mean to write 'If it doesn't say it's a match… etc.'? Or is a 'match' what I don't want (because it means the file is bad)?

@rautamiekka I don't know what happened to the other comments that were here (only those from the date of the original post are displaying), but this seems to have been a hardware problem -- i.e. with my modem/router. No errors were reported during the download of the .dmg but, as reported here, it failed both attempts. Thanks for your attempts to assist me with this.

I figured as much, although I weren't exactly sure if your modem was the exact culprit.

Modem was the culprit. Thanks again. Do you know what happened to all the other comments -- yours and mine (the ones that followed the first exchanges on Oct 18)?

Does LO delete comments?

My guess is as good as yours. It's entirely possible the Admins/Mods deleted comments which held no useful value. An asking site like this is pretty bad for long[ish] conversations and attempts to figure it out.

Dmg File Won't Open Mac

The term DMG is a file extension which means Apple Disk Image. This type of disk image data file is created on Apple computers using the Macintosh OS. The article provides an overview of DMG data files and several ways to open a corrupt DMG file or disk image files from the command line or free applications to view DMG file content in Windows. It prevents damage and corruption of DMG files by restoring DMG files.
These DMG files are similar to Microsoft Windows ISO, which are software installation files for Mac applications that also support the preservation of compressed files. The MIME type or Internet media type of the DMG file is an application / x-apple-disk image. The DMG file symbols contain structures based on different disk image formats. Some formats are described below.
⦁ Universal disk image format
⦁ New disc image format

Due to Damaged DMG Files
There are several reasons why a user cannot open a corrupt DMG file. Here are somewhat similar points:
⦁ Read / Write Process Interrupt: The DMG file is damaged by the “intermediate” habit of stopping the current process of the read/write process.
⦁ Cross-Platform Sharing: Sharing files between unsupported platforms can make DMG files irresponsible.
⦁ Physical Hard Drive Damage: Here are few chances where hard disk gets damaged due to scratches or some unknown reason. These sudden events can corrupt the DMG file.
⦁ Incorrect Resolution: DMG files are considered as physical disks. However, if you save DMG files to an external hard drive, improper ejection of the disk can damage the files.
⦁ Corrupt Header File: The header file contains crucial data within it. When something goes wrong in this file, the overall DMG file will also be damaged
