Cannot find the .vbox-extpack file

Post by i3100686 »

Dear all,

This is my first post in this forum; I read the "Posting guide" and hope I not miss any of the rules in it given.

As stated in the topic title I cannot find the .vbox-extpack file.

I downloaded the VirtualBox 6.1.38 package, installed it on my MacBook Pro 13" running MacOS X Catalina 10.15.7 (19H2026), and it works fine.

I also downloaded and expanded the Oracle_VM_VirtualBox_Extension_Pack-6.1.38.gz file, but I am cannot find the .vbox-extpack file in the folder resulting from file decompression.

The folder Oracle_VM_VirtualBox_Extension_Pack-6.1.38 contains the files:

Code: Select all

-rw-rw-rw-@  1 myUser staff    11K Sep  1 15:27 ExtPack-license.html
-rw-rw-rw-@  1 myUser  staff    19K Sep  1 15:27 ExtPack-license.rtf
-rw-rw-rw-@  1 myUser  staff    10K Sep  1 15:27 ExtPack-license.txt
-rw-rw-rw-@  1 myUser  staff    22K Sep  1 17:45 ExtPack.manifest
-rw-rw-rw-@  1 myUser  staff     6B Sep  1 15:27 ExtPack.signature
-rw-rw-rw-@  1 myUser  staff   577B Sep  1 15:27 ExtPack.xml
-rw-rw-rw-@  1 myUser  staff    48K Sep  1 15:27 PXE-Intel.rom
drwxrwxrwx@ 13 myUser  staff   416B Sep  1 17:44 darwin.amd64
drwxrwxrwx@ 13 myUser  staff   416B Sep  1 17:45 linux.amd64
drwxrwxrwx@ 13 myUser  staff   416B Sep  1 17:45 solaris.amd64
drwxrwxrwx@ 13 myUser  staff   416B Sep  1 17:45 win.amd64
I tried to rename to Oracle_VM_VirtualBox.vbox-extpack but, as expected, VitualBox gave an error when tried to load it. I also tried to rename the dowloaded .gz archive to Oracle_VM_VirtualBox.vbox-extpack, but again, as expect, returned the same error.

So, my questions are: "Am I doing something wrong, or is there no Extension package for MacOS?".

Many thanks in advance.

The downloaded file is the vbox-extpack, there is no .gz named download. Nor are you required to unpack it. Let VirtualBox do that.

I grab the download link and go to the directory and grab the files I need one at a time.

The download link is:
https://download.virtualbox.org/virtual ... 38-OSX.dmg

The directory holding the 6.1.38 download files is:
https://download.virtualbox.org/virtualbox/6.1.38

If you open the directory above you can download one of the following files (they are the same, but are names so that one has the version revision number in it:

Oracle_VM_VirtualBox_Extension_Pack-6.1.38-153438.vbox-extpack 01-Sep-2022 17:57 11M
Oracle_VM_VirtualBox_Extension_Pack-6.1.38.vbox-extpack 01-Sep-2022 17:57 11M

Dear AndyCot and mpack,

The issue seems to be due to the browser.
The same link used in Chrome saves a ".gz" on my hard drive, while used in Safari saves a file without the ".gz" that is ready to be installed.
Please, see the attached image.

As said, I tried to change the extension, as it seemed the issue could the there, but it did not work.

It should be due to some preferences I am not aware of.

Thank you both for your help!

Bests.

If the browser renames the download, you can rename it back.

This sounds like some sort of browser security feature to prevent, e.g., an exe masquerading as a JPEG. I don't use either Chrome or Safari so I can't comment on browser settings.

HI mpack,

Yes, I had the same though and tried to change the extension.
Doing so, the file was detected as readable in the file selection window but after confirming to load it, Virtualbox displayed an error.

Cheers.
