How to run MacOS on other platforms
It is possible to run MacOS in a visualized environment on any host that can run VirtualBox. The easiest way to do this is with Vagrant.
Disclaimer: Apple's MacOS EULA is a bit draconian on how you can get and where you can run MacOS. In US short term execution for purely integration purposes on other platforms, after you bought Mac hardware, may be protected by DMCA section 1201

How to get a high resolution logo of any company
Type the following into google: company name filetype:pdf site:companysite.com
Pick several PDF. Open and look for the logos. Zoom in close to check if they are vector and thus don't deteriorate when closely zoomed Make a snapshot of the logo blown up to the take your full screen. You could get it bigger than the screen size if you zoom in more, make multiple snapshots of each segment and then stich back together.
In photoshop crop it to contain the logo only. If you need to make it on a transparent background do a color range selection (works fine at the fuzziness of 40). Delete the selected region. Remove the background layer visibility so it does not show up through the region you just deleted. Remove white matte. Save as PNG to preserve transparency.
