“InSpectre” is an easy to use & understand utility designed to clarify
the many overlapping and confusing aspects of any Windows
system's ability to prevent the Meltdown and Spectre attacks.

As the application's textual display says..

In early 2018 the PC industry was rocked by the revelation that common processor design features, widely used to increase the performance of modern PCs, could be abused to create critical security vulnerabilities. The industry quickly responded, and is responding, to these Meltdown and Spectre threats by updating operating systems, motherboard BIOSes and CPU firmware.

Protection from these two significant vulnerabilities requires updates to every system's hardware–its BIOS which reloads updated processor firmware–and its operating system–to use the new processor features. To further complicate matters, newer processors contain features to minimize the performance impact of these important security improvements. But older processors, lacking these newer features, will be significantly burdened and system performance will suffer under some workloads.

Redis client mac gui. This InSpectre utility was designed to clarify every system's current situation so that appropriate measures can be taken to update the system's hardware and software for maximum security and performance.

Q:
On some of the computers, one or the other or both of the Enable/Disable Protection buttons are grayed out and disabled so that they cannot be used. What's going on?

Either of the Protection Enable/Disable buttons will be disabled when the button's respective vulnerability cannot be enabled or disabled by its user. For example, Since AMD processors have never been subject to the Meltdown vulnerability, the Meltdown button will be disabled because there's no way for its protection to be disabled. This would also be true (in the other direction) when a system has an Intel processor and any version of Windows that has not been updated for the Meltdown vulnerability. In that case the system is vulnerable and there's no way for the button to make it invulnerable.
Similarly, any computer whose firmware has not been updated will be vulnerable to Spectre attacks and, again, the button cannot make it invulnerable.
So, InSpectre will enable those buttons when the system's conditions allow the operating system to protect against the respective vulnerability, but the user may wish to disable that protection, where possible.
  • Release #1 — Initial release:
    The first release was triggering false-positive warnings from 3rd-party anti-virus scanners. This was probably due to a registry key the application uses to enable/disable the Meltdown and Spectre protections. Also, the language used in one of the text-explainers was confusing and self-contradictory.
  • Release #2 — Second try:
    This second release hides its use of the registry key that was upsetting so many anti-virus scanners. A pass through Virus Total shows that made a huge difference. And that confusing paragraph was rewritten into two, which are now presented more correctly. Let's see how this second try fares.
  • Release #3 — Raw Technical Data Display:
    InSpectre's more technically inclined users have asked for more information about how InSpectre makes its decisions. Non-Windows users have also asked for that information so that InSpectre could be run on Linux and MacOS machines (under WINE) to check the non-Windows machine's CPU support. As shown to the right, InSpectre release #3 adds a “Show Technical Details” item in the system control menu at the upper-left corner of the app. Click on the little “Spectre” icon and select the “Show Tech Details” item to display the raw data obtained by InSpectre's analysis of its operating environment.
  • Release #4 — Silent System Probe Option:
    When InSpectre is launched with the string “probe” in its command line, its Windows user interface will be suppressed and InSpectre will act like a command-line utility. It will assess its hosting system's status, then immediately terminate itself returning a decimal exitcode which encodes the eight “trouble bits” shown below, which itemizes any trouble. Therefore, for example, an exitcode of zero (0) is returned only by a fully secure system.
    Decimal
    Value
    Trouble Itemization
    1OS is not aware of the Meltdown vulnerability
    2OS is not aware of the Spectre vulnerability
    4The system is vulnerable to Meltdown
    8The system is vulnerable to Spectre
    16CPU does not support Spectre (microcode not updated)
    32CPU does not support low-overhead Meltdown protection
    64Meltdown protection disabled by registry setting
    128Spectre protection disabled by registry setting
    Since InSpectre's exitcode is the sum of the values shown above which are true for any specific system, the table above can be used to decompose InSpectre's probe-mode exitcode to determine the system's trouble.
    This zip archive: “InSpectre-Probe-Samples.zip” contains sample batch file and powershell script files for capturing InSpectre's exitcode. Note that an exitcode is not a “printed” output from the program—it won't be printed onto a command console. It is a value that can be obtained by another script or program which executes the program after it terminates.
  • Release #5 — Copy results to system clipboard:
    Earlier releases of InSpectre did not encourage copying the program's displays out of the application. Any region of the results can now be marked with the mouse and copied to the system's shared clipboard by using the standard Ctrl-C key combination. The application's system menu (under the small Spectre icon at the upper-left corner of the application window) also now contains a “Copy to Clipboard” option which will either copy a marked region or the entire textual content if no region is marked for copying.
  • Release #6 — Worked around a Microsoft bug and more . . .
    Users of an earlier version of Windows 10 (version 1703 ‑ the non-Fall Creator's Update) reported that InSpectre did not believe that their system had been patched for the Spectre vulnerability. Upon analysis, a bug was discovered in that version of Windows which affected the way 32-bit applications, such as InSpectre, viewed the system. This was apparently fixed in the later “Fall Creator's Update” (version 1709) but not in the earlier version. A 64-bit “probe” was added to the 6th release of InSpectre to work around this bug in version 1703 so that InSpectre would accurately reflect any system's true protection.
    And, while we were at it, the language presented in the summary was changed from “vulnerable” to “protected” so that “YES” was the good answer and “NO!” was the bad answer. :)
  • Release #7 — Added the display of the system's CPUID . . .
    Microsoft will be making Intel (and perhaps AMD?) processor microcode patches available for the most persistent Spectre Variant 2 vulnerability. These will become available over time as they become available from Intel and they will apparently need to be manually installed by interested Windows users. It is not yet clear whether Microsoft will be willing or interested in making these patches available for earlier versions of its Windows operating systems, but we can hope.
    The patches are applicable to specific CPU models only, which are identified by each chip's “CPUID.” For this reason, InSpectre now prominently displays the system's processor CPUID at the top of its system summary.
    Please check this page on Microsoft's website to see whether a microcode patch for your CPU, determined by its CPUID, is available at any time:
    KB4090007: Intel microcode updates

    You can also use your favorite Internet search engine to search for the string “KB4090007” which should always take to that page and to its related Microsoft Update Catalog page to obtain the specific Windows update.
  • Release #8 — Now shows whether an Intel microcode patch is (ever) available for Spectre.
    Intel has finished designing microcode update patches for its processors. On April 2nd, 2018, they announced that processors that have not yet been patched will never be patched. Their full statement is available in this PDF document. In that document, Intel specifies which of their many processors do have patches and which of their more recent processors will never receive updated firmware. Now that the industry has this information, this 8th release of InSpectre incorporates that list of CPUIDs and displays whether microcode firmware updates exist for the system's Intel CPU.

macOS security update: What are Meltdown and Spectre

The beginning of 2018 had the technology world in a frenzy. Two major processor vulnerabilities, namely Spectre and Meltdown, were discovered. Experts claimed the bug was unlike any security breach we’d seen in the past because it affected hardware. The vulnerabilities targeted all Mac computers and Windows PCs, and mobile devices — everything that carried an Intel processor inside was under threat.

Why is Intel processor vulnerability a problem?

What made Meltdown and Spectre possible (and so much troubling) is the very architecture of any modern processor. The core of the processor stores the so-called kernel data, which regular apps and processes normally shouldn’t have access to. Or so everybody thought. It appeared Meltdown and Spectre exploited a breach in hardware security, allowing a potential attacker app to break inside the 'processor gate,' read its memory, and even steal your passwords.

How Spectre and Meltdown are different?

The Meltdown attack gives way for a malicious app to access the protected memory of the OS itself and other applications. While Spectre flaw, acting in a more shadowy way, can make any program reveal its inner data which is much trickier to patch. As it appeared later, Intel Apple, Microsoft, and Linux software developers had known about the vulnerabilities and had been working on a fix when the issue was discovered in January 2018.

Is my Mac affected?

If your Mac is running macOS 10.13.2 or later, you should be protected against Meltdown attacks. The things are not that clear with Spectre: although the patches were issued, the users are still waiting for the fundamental CPU hardware design changes to ensure the Macs are 100% safe from a similar attack.

Exploiting these vulnerabilities requires installing a malicious program on your Mac, so you should be extra vigilant about the apps you install. Download software only from the trusted resources to make sure no malicious app can sneak in. Updating your Mac regularly can help fix security flaws: the new releases often contain security patches and Safari updates, so it's important to keep your Mac up to date.

  1. Go to Apple menu > About this Mac.
  2. Click Software Update to check for updates.

What did Apple do about this?

As soon as the first reports came out, most technology players started working feverishly on patches for their devices. To Apple’s credit, it took just a few days for the company to release the fix, which aimed to seal the security hole. But as hardware tests showed, the patches to macOS High Sierra seriously affected the OS performance, according to some estimates, slowing Macs down by 10-30 percent.

I feel my Mac got slow, how do I speed it up?

Has your Mac performance been hit? First off, you should follow Apple’s advice and update your Mac. Next, you can try to gain back some performance for your Mac by doing a bit of tune-up under the hood.

Tips to combat macOS productivity loss

Step 1. Remove unnecessary startup items

You can significantly speed up your Mac’s booting by disabling some apps in the startup catalog. According to MacPaw engineers, adding just 5 extra Login items slows down average boot time by 20 seconds.

  1. Go to System Preferences > Users & Groups and select your username.
  2. Next, click Login Items and use the “—“ button to switch off extra apps you don’t need.

Step 2. Uninstall unwanted and suspicious apps

Not only can you win back some drive space (which also translates into speed), you will secure your macOS from unwanted apps meddling with your sensitive data. But how do you delete an app safely? Apparently, dragging it to the Trash isn’t the best option — some leftover parts and pieces are still left on your drive.

See our easy guide on “How to Uninstall Apps on a Mac.” You’ll learn the manual way and the easy way.

Step 3. Delete browser extensions

Browser add-ons are potential gates to run malicious scripts on your Mac. While no Meltdown or Spectre attack has yet been discovered “in the wild,” your browser will surely be one of their entry points.
To delete extra plugins and extensions from your browser:

Step 4. Use CleanMyMac X to mitigate Mac vulnerability
