Why that 40% performance hit for full 'ZombieLoad' mitigations probably won't affect you
A full mitigation could be applied, eliminating any possibility of the issue affecting a Mac, but in the process it disabled hyper-threading and, by Apple's estimates, reduce system performance by as much as 40%. This reduction only applied to anyone who enabled the full mitigation in the Mojave update, as well as those who installed Security Update 2019-003 for High Sierra and Sierra and similarly enabled it.

This potential loss of performance immediately caused uproar from concerned users, though the anger is overblown, and not specific to the Mac.

A proof of concept for ZombieLoad showing it is able to monitor a user's browsing on a virtual machine on the Tor browser.

A loss of performance is only an issue if the person managing the Mac in question goes full bore on the mitigation. Unless the Mac is being used for highly secretive tasks, the user is a potential subject for hacking attempts by a sophisticated bad actor, or some other value-based reason, there isn't really a need to turn on the full mitigation.

And, disabling Hyper-Threading will have the same impact on Windows systems too —which is why Microsoft doesn't advise it.

Safari and sourcing

For the vast majority of Mac (or Windows) users, there is no need to enable the full mitigation. As per Apple's notes on the fixes, the bulk of the alterations were made to Safari, preventing exploitation of the vulnerabilities via Javascript on a malicious website, and with "no measurable performance impact" to most users.

Along with Safari, those worried about the vulnerability, or malware in general, could easily take the time to update their security settings within macOS to download apps only from the Mac App Store. As apps from there are signed by Apple to make sure they aren't tampered with or altered, it makes the apps far safer to download than versions acquired from the internet.

That isn't to say that you shouldn't download software from other sources, but seasoned users who are capable of knowing a good source from a malicious one can easily avoid the potential hazard of installing malware that uses the vulnerability.

Notarizing Automator applications | Der Flounder
Beginning in macOS 10.14.5, all new or updated kernel extensions and all software from developers new to distributing with Developer ID must be notarized in order to run. In a future version of macOS, notarization will be required by default for all software.

How to fix OS X installation 'can't be verified' error - TechRepublic
If you're performing a clean install of OS X, that is slightly more difficult, but it can still be easily done from the Terminal. To access it, go to Utilities | Terminal from the OS X Installer Menu Bar. Once launched, enter the following command into Terminal and press the Enter key to execute it.

date [[[mm]dd]HH]MM[[cc]yy]
Command: date


cc = century (or the first two digits of the year)

yy = year (or the last two digits of the year)

mm = month (two-digit month)

dd = day (two-digit day)

hh = hour (two-digit hour based on military time)

mm = minute (two-digit minute)

NuTek Duet Specs:
The NuTek Duet is a reverse-engineered "semi-MacOS-Compatible" which features a 33 MHz 68030 processor, 8 MB of RAM, a 120 MB hard drive, a Mac-Compatible SCSI port, audio-in and audio-out jacks, and 2 NuBus slots. The Duet is the same as the One, but it has a 486/66 in the same case to run DOS and Windows. Technically, this is not a MacOS-Compatible since it doesn't run the MacOS, but it was an interesting attempt to make a MacOS-based computer before MacOS licensing.

NuTek Mac Clones:
NuTek made an inexpensive, reverse-engineered line of semi-MacOS-Compatible computers from early 1993 to early 1994.

The NuTek line of computers could not run the MacOS, but instead used a proprietary NuTek operating system and ROM that had "limited support" for AppleTalk, was able to run some Macintosh control panels and "most" applications, as well as support some Macintosh SCSI devices and NuBus cards. The NuTek series was said to outperform a Macintosh IIvx, when it performed at all, but NuTek had so many software and hardware compatibility problems, particularly with NuBus cards, that even with such a low price it was unappealing to most.
If anything, NuTek proved that uncontrolled "cloning" of the Macintosh would result in the same type of compatibility problems familiar to the Wintel world. NuTek went out of business in 1994.

Brian Howard Obituary - San Jose, CA | Mercury News
Brian Douglas Howard Computer designer and musician, died of cancer on February 1st at his home in Portola Valley, CA; he was 65 years old. Born on March 23, 1944, in Cambridge, MA, he grew up in Norman, OK. His father was a physics professor at the University of Oklahoma, and his mother was a classical pianist. He attended Stanford University on a National Merit scholarship, graduating in 1967 with a B.S. degree in electrical engineering. In 1978, he became the 32nd employee of Apple Computers. As editor of the famous computer manuals, he combined meticulous language skills with exhaustive computer knowledge to create user-friendly instruction books that helped to popularize the nascent company's products. One of the original four members of the Macintosh Project team, Brian Howard helped to revolutionize the personal computer; his signature was molded into the case of the original Macs. He eventually moved from computer documentation to architectural hardware design, which was more commensurate with his engineering background. At Apple, where he was the longest continuous employee, he was promoted to the level of DEST (Distinguished Engineer, Scientist or Technologist), in recognition of his exemplary work. He was celebrated among his colleagues for his fertile imagination and communication skills.

The Industry Change That Didn’t Happen

In 1999, Compaq was going through a management crisis. The board appointed me Acting CEO in April. Midway through  my four-month tenure I received a call from Steve requesting that we get together to discuss an “important matter.”

Curious, I flew to the Bay Area, and met Steve at an Indian restaurant in Menlo Park. It was a haunt of his; he could always get great vegetarian meals there.

After we finished with the amenities and reminiscences, we got to the purpose of the meeting. Steve wanted Compaq to offer the Apple operating system on its PC line, adding to the Microsoft OS that had always been our sole OS. At the time, Compaq was the world’s largest manufacturer of PCs. Our adopting the Apple OS would be seen as a feather in Apple’s cap (and a pretty visible slap at Microsoft).

The catching up with Steve was fun, the food was great, but the OS idea never gained traction. Upon further analysis, it didn’t make sense for either Compaq or Apple. Compaq wasn’t about to declare war on Microsoft, our partner from our birth in 1982, and Steve had second thoughts about licensing their crown jewels.

Steve Jobs wanted Sony VAIOs to run OS X - The Verge
Japanese freelance writer Nobuyuki Hayashi, who has covered Apple for over two decades, quotes ex-Sony president Kunitake Ando recalling a 2001 meeting between him and Jobs in Hawaii. After playing a round of golf with other Sony executives, says Ando, "Steve Jobs and another Apple executive were waiting for us at the end of the golf course holding VAIO running Mac OS." Jobs had shut down the Mac "clone" business years earlier but, according to Ando, admired Sony's VAIO line so much he was "willing to make an exception." The timing, however, was bad. Sales of the company's Windows-powered laptops had just begun taking off, and the negotiations to make Mac-compatible VAIO's ultimately came to nothing.

As far-fetched as the story sounds, Jobs had a well-documented respect for Sony, and a good relationship with its executive team. Ando's account of the 2001 meeting corroborates a well-reported anecdote about the secrecy of the Intel team at Apple, which claimed that Apple's ex-SVP of software engineering Bertrand Serlet made the team "go to Fry's and buy the top of the line, most expensive VAIO they have" to demonstrate the possibility of OS X on Sony hardware.
