If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available. If the Mac logic board was just replaced, you may be offered only the latest macOS that is compatible with your Mac. The last time the design of macOS (or rather Mac OS X) changed significantly was in Yosemite, when it had an overhaul, at the hands of Apple's design guru Jonathan Ive, to bring it into line with iOS.

Mac OS X 10.7.3 (Lion) inherently contains many desired security features; however it takes a few moments for the user to enable most of them. It's the ideology of convenience versus security and as it is well known Macs are quite convenient. This article will discuss how to further harden the Mac OS X environment and raise users up a few notches from the low-hanging fruit category.

General Security

Built-in – Using the operating system's native toolset available for the user to configure and raise the security posture from its default ‘convenient' settings. For example System Preferences, Keychain Access, Software Updates.
Third-Party – Using third-party vendors to further enhance the native system usually with additional front-ends. For example 1Password, Little Snitch.

Encryption Security

Built-in – Using native available encryption. Apple comes with FileVault 2; a whole disk encryption feature allowing users to have their data made irrecoverable in an event of theft, loss, physical compromise.
Third-Party – Using both open source and/or commercial encryption suites such as TrueCrypt, Mac GPG, Symantec's PGP Desktop.

Malware Security

Built-in – Using native available malware protection. XProtectUpdater which updates the ‘safe downloads list'.
Third-Party – Using both commercial and/or free anti-virus/anti-malware suites such as MacScan, Sophos, ClamXAV.

For the most part by configuring and enabling the built-in security features that Apple Mac OS X Lion has to offer third-party utilities turn into a ‘want' more than a ‘need'.

Post-Installation

Security begins at… well the beginning. For most users this is known as post-installation. Just around where they would turn on their Macs for the very first time. The following 21 recommended security tips are not only recommended but also encouraged:

1. Create Your Computer Account

During this screen enter a password make sure the checkbox labeled ‘Require password when logging in' is checked. If a password hint is entered make sure it doesn't reveal to a potential attacker the password. I like to put in an appropriate message directly to the attacker such as ‘Sorry buddy, it isn't that easy – try something else'. Note that Apple states 'Enter a hint to help you remember your password. Anyone can see the hint, so choose a hint that won't make it easy to guess your password.'

2. System Preferences : Change Lock Security Feature

Locking system preferences configurations is ideal in a secure world as to make changes requires authentication with administrative credentials. Of the 29 default System Preferences 11 locking options are offered by default in Security & Privacy, Energy Saver, Print & Scan, Network, Sharing, Users & Groups, Parental Controls, Date & Time, Software Update, Time Machine, Startup Disk. The padlock icon is on the lower left and does not take a password to enable; but takes a password to disable.

3. System Preferences:Security & Privacy:General

The following recommendations are obvious, but only a few are enabled by default verify the following are enabled.

Require password immediately after sleep or screen saver begins.

For all accounts on this computer:

  • Disable automatic login
  • Require an administrator password to access system preferences with lock icons
  • Automatically update safe downloads list'
  • Disable remote control infrared receiver. 'This computer will not work with any remote' otherwise if a remote is used make sure it is paired ahead of time. (If it is left unchecked or unpaired any Apple remote will be able to control the Mac by default)

4. System Preferences:Security & Privacy:FileVault

Turn On Filevault

  • Save the recovery key (text or screenshot)
  • Enable Do not store the recovery key with Apple
  • Restart the Mac to begin the encryption process
  • Upon restart the background will now be gray and feel slightly different (reminding the user FileVault 2 is being used)
  • Returning to System Preferences on FileVault it will display the time remaining for encryption process to complete (depending on the hard disk size and contents the time to completion may vary – it is recommended to let this run overnight without disturbance).

5. System Preferences:Security & Privacy:Firewall

Start the firewall (by default it is disabled)
It is recommended to configuring the firewall in the following order:

  1. Enable Stealth Mode
  2. Disable Automatically allow signed software to receive incoming connections
  3. Block all incoming connections

Note this will allow the Mac to use the network ‘normally' however will not allow potential attackers to detect or attack the Mac easily when compared if these features were left disabled.

6. System Preferences:Security & Privacy:Privacy

I have bombed mac os. Naturally these settings are for the truly paranoid and in trade will not automatically allow applications or Apple have an understanding on the issues or whereabouts of the Mac.

  • Disable Location Services
  • Disable Send diagnostics & usage data to Apple

7. System Preferences:Desktop & Screen Saver:Screen Saver

When not at the keyboard the screen should be lock. This is good practice for the security conscious. A simple method to lock the screen is to enable a hot corner where the mouse can be positioned to activate the screensaver in essence locking the screen.

Choose a Screen Saver and Choose Hot Corners and select an Active Screen Corner

Note: Another way to lock the screen using the mouse would be to open the Keychain Access app Preferences and enable Show keychain status in menu bar. This adds the Lock Screen feature and a padlock icon in the menu bar for easy access to lock the screen with the click of the mouse.

8. Software Update

Now that the system is secured on the network Software Update is the next logical feature to run so that the Mac acquires the necessary security updates to the machine.

Note: Prior to doing this it is recommend waiting for FileVault to complete the encryption process before downloading the updates (off the network). FileVault is known to be sensitive to disk activity during the encryption phase.

For the updates themselves It is always recommended to Show Details and review the items prompting to be installed; for the most part the user is safe but it can never be assumed. Install the new software available for the Mac. If it is necessary to choose priority due to bandwidth limitations select the Mac OS X Update Combined first as that has most of what is needed first. Note: If Software Updates downloads are giving issues they can be downloaded as dmg files from Apple's support site: http://support.apple.com/downloads/

Remember to run Software Update a few times to make sure that everything is updated. Sometimes after updates are downloaded and installed after restarting there are a few more. It is best practice to check and make sure to get the message 'Your software is up to date'.

9. System Preferences:Bluetooth

If Bluetooth isn't being used disable it by clearing the checkbox labeled On. If it needs to be used for the magic mouse or other bluetooth device and and doesn't require it to be set as Discoverable then also clear the checkbox labeled Discoverable; thus lessening potential attack vectors.

10. System Preferences:Sharing

Change the Mac's name – for best results give it a name that doesn't stand out to potential attackers by revealing a tasty target. Apple by default will give the computer name as the first user's first name and then the type of computer – i.e. ‘Israel's Mac Mini'. For example to seem really uninteresting a name such as ‘Tiger Powerbook' may discounted by an attacker as a crusty box be passed on for newer technologies.

11. System Preferences:Users & Groups

Make sure to only allow user to administer the computer if it makes sense; don't just do it by default – add parental controls if need be; however Apple's Parental Controls are simple and rather limited; most savvy individuals can bypass these tools.

While here verify that all services are disabled by default, and be careful to enable anything – be sure to understand what type of risks it puts the Mac and ultimately the end-user in.

12. System Preferences:Date & Time

It may not seem like a big deal but the Mac is a precision machine that relies on date and time to make sure things are happening that are supposed to be happening. If there are new issues the first thing that should be checked is the date and time. Especially if it is password related; some systems won't tolerate an environment if it is more than 5 minutes off. By default Macs are synched to the apple time server time.apple.com. (as long as DNS hasn't be compromised along the way this should suffice)

13. System Preferences:Software Update

Verify that Check for updates weekly and download updates automatically are enabled. For the most part updates (especially security related) should be gotten and applied sooner than later.

14. System Preferences: Spotlight: Privacy

Some things don't need to be indexed and therefore should remain private. Not only does not indexing them speed the performance of spotlight. It also adds security by not storing the location of certain data. To do so indicate and add which locations shouldn't be searched.

15. Applications:Safari: Preferences: General

In Safari's General Preferences disable ‘Open 'safe' files after downloading. What Safari may think as safe; may not be. They will be downloaded to the Downloads folder where the user can open then and extract them as needed.

16. Applications:Safari: Preferences: Autofill

Verify User names and passwords is set to disabled. Don't use this if the ramifications aren't clear.

17. Applications:Safari: Preferences: Security

By default all items are enabled; be sure to gloss over time and verify that's what is needed. Disabling one or more of these may alter the user's browsing experience.

18. Applications:Safari: Preferences: Privacy

Privacy is another pre-populated configuration that doesn't require manipulation unless it is necessary.

19. Applications:Safari: Preferences: Extensions

Extensions should be off unless extensions are being explicitly used. (available from extensions.apple.com)

20. Menubar: Wi-Fi

If Wireless connectivity is not being used it should be turned off to eliminate accidental connections and exposure to untrusted networks.

21. Post-boot

Unbeknownst to most Mac users Apple computers have a fantastic built-in feature that allows the physical machine to be locked down (with a password) from further tampering and/or unauthorized examination. For example booting up to optical media or alternate disk thus bypassing the built-in authentication mechanisms to gain access to the unencrypted contents of the hard disk ala the ‘Evil Maid Attack'. To enable this feature boot to the Lion recovery partition (during startup hold the Command+R keys on Lion 10.7.3) and in the Mac OS X Utilities menu navigate to Utilities-> Firmware Password Utility to Turn On Firmware Password. [Note: do not forget this password as it will be quite difficult to gain access back into the machine through normal means, and may require consultation with the Apple Genius at added expenditure]

Securification

For additional configurations and actions about Apple Mac Security peruse through Apple's security guides http://www.apple.com/support/security/guides/

Users unaware of all the fantastic tool Mac OS X Lion comes with to further protect their data and privacy should be encouraged to consider setting a few if not all the aforementioned built-in security features. Doing so only takes a few moments of time. Hopefully in the future Apple will attempt to suggest enabling these security features automatically (and conveniently) during post-installation especially for new users via a simple security wizard. One key facet to security is preparation and to quote Benjamin Franklin: 'By failing to prepare you are preparing to fail.'

Which Mac operating system is the best is a topic of numerous debates among Apple fans.

Since the mission of this blog is to refute myths and legends around Macs, it's time for me to provide my 2 cents about the issue on hand. While everything below is just my opinion, as a long-time Mac user and veteran software engineer, I hope my opinion worth something.

The best Mac OS version is the one that your Mac is eligible to upgrade to. In 2021 it is macOS Big Sur. However, for users that need to run 32-bit apps on Mac, the best macOS is Mojave. Also, older Macs would benefit if upgraded at least to macOS Sierra for which Apple still releases security patches.

How to Tell Which macOS You Are Running

To find out which macOS is currently running on your Mac, follow these steps:

  1. Click on Apple logo in the top left corner of the menubar
  2. In the dropdown click on the first item: About This Mac
  3. The first line in the Overview tab is the name of the current OS.

What Version of OS Can My Mac Run?

Not all Macs can be upgraded to the latest OS version. For instance, old Macs powered by PowerPC CPUs cannot run OS intended for Intel-based computers. Also, some versions have hardware limitations.

For instance, Mojave cannot be installed on MacBook Pro earlier than Mid 2012 model.

Check below to know exactly what version of OS your Mac can run.

Which OS is Best for my Mac

Anytime someone asks me which OS is best for them I always suggested going with the latest. Things have changed recently, however.

Should I Upgrade to macOS Catalina or Big Sur?

While personally I like macOS Big Sur and have it installed on my MacBook Pro, it comes with serious breaking changes.

The first issue is compatibility.

Big Sur is a transition OS which is designed to help Apple to move from Intel processors to their own chips on ARM.

After I installed Big Sur on my MacBook Pro mid 2020 (pre-Silicon), most of my apps, including Microsoft Office, were working as expected.

However, my VMWare Fusion 11 does not start anymore, so I have to purchase a new license if I want to keep using it (or roll back to Catalina). Luckily, I took a full backup before the upgrade.

The second breaking issue is the lack of 32-bit app support.

macOS Catalina and Big Sur can only run 64-bit apps.

If you wondering whether you should upgrade to macOS Catalina or Big Sur, first verify that you don't have any 32-bit apps. But first, take a back up, so you can go back in case something breaks after the upgrade.

For instance, I had to remove uTorrent after upgrade. And I didn't know that uTorrent is 32-bit!

How to Know If App is 32-bit or 64-bit

To find out whether the app on your Mac is 32-bit or 64-bit follow these steps:

  1. Click on Apple logo in the top left corner of the Mac screen
  2. Click on About This Mac option
  3. Click on System Report button in Overview tab (first one)
  4. Scroll down to Software -> Applications
  5. Find the app and check Kind

Which macOS Should I Use

If you have an older Mac which is not eligible to upgrade with some latest software or hardware, I'd suggest upgrading at least to Sierra (or better High Sierra) for the following reasons:

  • Sierra is still supported by Apple, and it gets security updates
  • APFS file system is available
  • It supports Siri
  • Significant security improvements

The most important point when choosing the best OS is the ability to get security updates. While Apple generally does not announce the OS end of life dates, it is possible to know when they stop releasing security updates from this page.

For instance, according to the page, the last security update for OS X Yosemite was released on September 12, 2017. The last update for OS X El Capitan was in July 2018, and Carnegie Mellon University confirmed that El Capitan's end of life date was August 2018.

Snow Leopard Myth

I know that some users on forums believe that the best OS version for Macs was Snow Leopard. But that is a myth. And I know how such myths get created.

Once I worked in the company, which was selling a 20-year old product. And customers were still using and didn't want to switch to new versions, because the old one was rock solid.

I then talked to the engineer who worked on the project, and he revealed that the product was a total disaster when it was first deployed. Engineers had to work on-site for almost a year in order to fix all bugs.

After five or so years of polishing the product, it becomes virtually bug-free, and nobody now remembers how bad it was when it was first rolled out. A similar thing happened Snow Leopard, and it was recognized as best mac os version after some time.

How to Update to the Latest Version

There are two ways to update to the latest OS version on Mac:

  • From the Software Update section in System Preferences
  • Use a download link

Using Software Update

This is by far the best option, but it only available if you have Yosemite, or later OS installed already. Core9000 mac os. If you enabled automatic updates, then Mac will inform you that the next macOS is available.

Just open System Preferences, go to Software Update and click on the Upgrade Now button.

Better Horses Mac Os 11

This method is also best if wondering how to check if you have the latest version of OS installed on your Mac. Only the version compatible with your hardware will appear here.

For instance, my the latest version for Mac Mini 2012 is Mojave, I can't install anything newer than that.

If you are having problems with updates or having issues post-upgrade check my post about troubleshooting macOS.

Using download links

For older systems or in case you need to downgrade, you have to download a standalone installer in DMG format. DMG stands for disk image, similar to ISO, just different formats.

After downloading the installer, just double click on it and follow instructions. Again, do not forget to take a backup before the upgrade. https://downhup936.weebly.com/mechanic-war-mac-os.html.
