I have joined a new company and since then some things have changed. I replaced my old friend Lenovo ThinkPad to a MacBook Pro. I should confess that it has been a new learning curve for me, MacBooks require some knowledge that are different from the ordinary OS. So, recently I tried to download the ISO Oracle V41362-01.iso which is the “Oracle Linux (6.5.0.0.0) for x86 64 bit”.
I went to https://edelivery.oracle.com/ and filtered for “Oracle Linux (6.5.0.0.0) for x86 64 bit” and then I found the content of the image below:

It is clear to see that the image size is 9.0 GB. However, for some reasons I was having hard time to understand why the download file was 1.5 GB every time that I tried. I had a very different understanding than before.

I thought okay, maybe this is a different thing on MacBook. Then I mistakenly tried to use this file as my OS image and of course it was not the right file so I got this error:

Then I thought about it for a while and suddenly “Gotcha!”. I clicked at the *.dmg file and realized that this 1.5 GB content file is the Oracle Download Manager. So lessons learned, if you are using MacBook this may be new for you as it was for me but in the end no hard feelings, we are always learning!
Follow the screenshots of the Oracle Download Manager:
