macOS alternatives

[rsharifnasab]

Few applications can be installed in Mac as well as Arch Linux, but they are mentioned as "-" in the readme.md

• Calendar: cal is available, jcal is also available with brew install jcal
• The fetch software packages are also available, although screenfetch doesn't work well. So we can name tokei and onefetch
• Top: btop is available with brew install btop.
• Speedtest also offers a macOS client, available via: brew install speedtest-cli.
• Latex: On macOS, one can have tectonic, which is handy and easy to install; in addition to that, a good TeX distribution is mactex, which is batteries included TeX distribution, although installation size is enormous (~5GB). It could be installed with brew install mactex.
• Finally, tldr, jq, and jless are also available to download easily with brew.

I am not using OSX for a while, so I really appreciate for mentioning these. I will update README and related scripts.
