1. A mac can play a fair amount (such as the Spiderweb games, said name being the website) but 'modern gaming', even ones with more simple 3d graphics, just isn't one of them for the most part. Perhaps the recommended requirements for the game, of which is 1050TI, are aimed at future content.
2. If you don’t have a remote server to try this with, you can try it out between Mac OS X machines or with localhost if you enable ssh and Remote Login on the Mac beforehand. The basic syntax to use scp (secure copy) for securely downloading remote files is as follows, replacing user, server, path, and target as appropriate.

The game is set in a containment site of The SCP Foundation, a secret organization dedicated to containing and researching creatures, items and places that. Enter to Search.

In Terminal, you can move and copy files locally or remotely using the mv, cp, and scp command-line tools.

Tip: It’s easier to move and copy files using the Finder. See Organize files in folders.

Move a file or folder locally

• In the Terminal app on your Mac, use the mv command to move files or folders from one location to another on the same computer. The mv command moves the file or folder from its old location and puts it in the new location.

  For example, to move a file from your Downloads folder to a Work folder in your Documents folder:

  % mv ~/Downloads/MyFile.txt ~/Documents/Work/MyFile.txt

  You can also change the name of the file as it’s moved:

  % mv ~/Downloads/MyFile.txt ~/Documents/Work/NewFileName.txt

See the mv command man page.

Copy a file or folder locally

• In the Terminal app on your Mac, use the cp command to make a copy of a file.

  For example, to copy a folder named Expenses in your Documents folder to another volume named Data:

  % cp -R ~/Documents/Expenses /Volumes/Data/Expenses

  The -R flag causes cp to copy the folder and its contents. Note that the folder name does not end with a slash, which would change how cp copies the folder.

See the cp command man page.

Copy a file or folder remotely

• In the Terminal app on your Mac, use the scp command to copy a file or folder to or from a remote computer.

  scp uses the same underlying protocols as ssh.

  For example, to copy a compressed file from your home folder to another user’s home folder on a remote server:

  % scp -E ~/ImportantPapers.tgz username@remoteserver.com:/Users/username/Desktop/ImportantPapers.tgz

  You’re prompted for the user’s password.

  The -E flag preserves extended attributes, resource forks, and ACL information.

  The -r flag, which isn’t used in this example, causes scp to copy a folder and its contents.
