LibreOffice on an USB-Stick working on Windows AND OSX?

Hi!

I promise I tried to squeeze out Google, but didn’t find an answer…
Since my laptop is slowering down every day (it’s running XP) I decided to run Ubuntu on it (unfortunately not done yet). Concurrently I wanted to stay away from Microsoft at all so I ran into LibreOffice (still testing on my Windows).
So I would have Linux, my work has Windows and at my university I have to work with Mac. Simple solution would be to use online office, but the network at work blocks Google Drive - so here is my question:

Is it possible to make a USB stick that gives me the same work space (i.e LibreOffice) for all three OS with no admin rights? I wouldn’t mind to have a “installation” for each OS (size doesn’t matter, in a pinch I have to buy a BIG one…), but the documents have to be accessible on the stick (since Google Drive or Dropbox are blocked at work).

Hope you can help

@ Googlefisch - Simply just take your portable version and plug your stick in to a Mac or a Linux machine.

I think the portable version is only made for Windows

What @jiero said - the builds for the various OS’s are OS-specific (surely!). The actual documents are interoperable, of course. I regularly use LO 4 on two different *buntu type things (Lubuntu, and Linux Mint 13), and two different Wins (7 and XP). No problem moving files between them on a USB stick. Is Dropbox an option for @carnendil? Works very well for me.

@dajare, I understand from @Googlefisch’s question that he cannot access either Google Drive or Dropbox from his job’s computer.

@carnendil - Doh! So he did say. Sorry about that.

Thanks for your help! As @carnendil said I don’t have access to Google Drive or Dropbox, but as I understand so far I need a “special” partition so both Windows and OS X can read it.

LibreOffice Portable from PortableApps.com (100MB download, 224-330MB installed) works very well under Windows.

Another option is winPenPack’s X-LibreOffice (215.31 MB).

For Mac OS X you can download FreeSMUG’s LibreOffice (163.6MB download). I haven’t ever used it, and please note that this is LO 3.3.0 and the website says for Intel computers only.

And good luck with your new Ubuntu! (or derivative, think Lubuntu for an XP-era laptop).

Could this information be placed at the download selection side of LibO? Would be helpful

@ROSt53 Good point, seeing as the only Portable version linked to is by PortableApps.com

Thanks for this info, I didn’t find a portable Libre Office for Mac… Strangely I couldn’t make a working stick with PortableApps and LibO Portable for Windows at all… Told me everytime that the installation file (for LO) was corrupted… But I’ll give another try.

@carnendil: Lubuntu is a good point, thanks.

If the Mac you are wanting to run PortableApps.com’s version of LibO Portable is your own, I suggest you install Wine (http://www.winehq.org) which lets you run Windows Apps on non-Windows Operating Systems such as OS X and Linux. However, as there is no pre-built package for Mac available, you need to follow the instructions on their wiki to install it.

Thanks for your help, but I don’t have admin rights neither on Windows at work nor on OS X at the university…
