The first limiting thing here are your rather sedate CPU, which will not really support a demanding user interface. Mint would be OK, but Ubuntu would probably be sluggish.
The second thing is your memory. The MSI site says that computer is available with 512 MB or 1 GB, expandable to 2 GB. If you have 1 GB, Mint will be fine. It would run in 512 MB, but it would be a tight fit and AntiX MX (rather than the ordinary AntiX) would be a good choice.
As for looking like the Mac, Linux desktops can be configured and extra bits added, so I anything is possible. Move the panel, add a pager to it, change the theme and icons ... that should help.
For installation, you'll need three partitions: root (for the OS and programs), home (for your own files -- Mint will let you encrypt this during installation), and swap (for hibernation or if memory runs out). All can be logical partitions within one extended primary partition: Linux doesn't require booting from a primary partition, unlike Windows. See this for the details:
