Simulate a Fake Kernel Panic in Mac OS X with iPanic iPanic is a free app that perfectly imitates a kernel panic, complete with a slow screen draw and inability to use the mouse or keyboard. It works in all versions of OS X, so it doesn't matter what is running, you can simulate a kernel panic with this prank app. Hi, I installed High Sierra on my Hackintosh earlier today, and I'm getting a kernel panic whenever I try to boot to the new install. I followed this guide, with the exception of I could not get the OS from the App Store (because it's no longer available.) But I had an install drive for High. It is the latest Mac operating system that functions on the Mac devices. The new version is name after the Santa Catalina Island, majorly called as Catalina and one of the Channel Islands off the coast of Southern California, which is apparently, is the inspiration behind the systems. Q1: What ‘s New in macOS 10.15 Catalina. Santa Santa is a binary authorization system for macOS. Apple followed this even when they released Mac OS 10 UNTIL they realized they were closing in on Mac OS 10.9.9. Apparently panic set in or they were wedded to the number 10 so they released MacOS 10.10.0 and called it a Major New Release but only giving it an Important Update number.
When your Mac keeps restarting or unexpectedly tells you that you have to restart because of a problem, that's a kernel panic.
There are few things more terrifying when using a Mac than the dreaded kernel panic. A kernel panic occurs when your Mac runs into a problem that is so serious it is unable to continue running. When it happens, your Mac displays a dark grey screen with the words 'You need to restart your computer. Hold down the Power button for several seconds or press the Restart button.'
How to stop a kernel panic?
The only way to fix a kernel panic error is to do exactly that and restart your Mac. Soon, you will fly mac os. Fortunately, kernel panics are very rare these days and when they do occur, restarting your Mac may be all you need to do to never see one again.
If you suffer repeated kernel panics, however, you'll need to investigate the cause and solve the problem — it could be a conflict between poorly written apps or services, or a problem with hardware. The software is the most likely culprit. But thanks to apps from Setapp, fixing problems with software and avoiding kernel panics is very easy.
Tools to fix Kernel Panic
A collection of tools that keeps your Mac from going grey. Get your hands on it and stay on the safe side.
Here's how to vastly reduce your chances of needing to fix a kernel panic in the future.
Hardware
- Shut down your Mac and disconnect all hardware except your keyboard and mouse. If you use a third-party keyboard and mouse, swap them for the Apple versions, where possible. Restart your Mac. If your Mac runs ok and there are no more kernel panics, it's likely a device connected to your Mac was to blame.
- Shut down your Mac again and re-connect one device. Restart your Mac. Repeat this process until you get another kernel panic. When that happens, you'll know the last device you connected was the culprit. You can now either use your Mac without the device or check to see if it has updated drivers and install those, then try again with the device connected.
Software
- First, rule out a deep-rooted problem with macOS. Restart your Mac in safe mode by holding down the shift key when you restart. This disables login items, kernel extensions, and all fonts not used by the system. It also does a check of your startup drive's directory structure. If you can reboot in safe mode and use your Mac without a kernel panic occurs, the likely cause of the problem is files installed by an application or a login item.
- If you experience a kernel panic in safe mode and you've ruled out a problem with hardware connected to your Mac, the problem could be your Mac's basic hardware or system. Try doing a clean install of macOS, and starting from there.
- Assuming running in safe mode worked, you can reboot normally and use the techniques below to reduce the likelihood of experiencing a kernel panic in the future.
What's causing Kernel Panic? Identify potential problems
It can be a million reasons why your Mac keeps restarting. The best way to identify what's wrong is use system monitoring app like iStat Menus. It makes it easy to track the performance of your Mac and see whether any applications are hogging resources, like CPU cycles or RAM.
- Launch iStat Menus, and set up monitoring.
- Use the Dashboard to choose which components you want to display in the menu bar. At the very least, choose CPU.
- Click on CPU in the menu bar to see which processes are consuming the most cycles — it's an indication that an app or system component is having problems. If an app consistently uses a significant percentage of CPU cycles, uninstall it using CleanMyMac (see below) and reinstall it.
- It's also a good idea to use the sensors tab to keep an eye on your Mac's fans. An overheating Mac is likely to run into problems.
Uninstall applications with CleanMyMac
CleanMyMac allows you to easily uninstall problematic login items and applications.
To uninstall an application:
- Launch CleanMyMac (if you haven't already installed it, launch Setapp, search for it and click Install).
- Click on Uninstaller in the Application section in the left-hand window. Navigate to the application you want to uninstall and click the checkbox next to it.
- Click Uninstall
To uninstall a login item:
- Click on Optimization in the Speed section, then Login Items.
- Navigate to the login item you want to uninstall and click the checkbox next to it.
- Click Perform.
You can do the same for System Preferences panes, browser extensions, audio plugins, and other system files. Before you attempt to remove something, however, make sure you know what it does and how its removal will affect your ability to use the application it is associated with.

Clean up your hard drive / SSD with Mac cleaning tools
While you're troubleshooting and solving problems with your Mac, it's a good idea to clean up its hard drive or SSD and remove duplicate files. There are a couple of apps available in Setapp that make this a breeze.
Disk Drill allows you to quickly identify files that are taking up lots of space on your drive and remove them. It's quick and easy to do and can free up several gigabytes.
Gemini identifies duplicate files on your Mac and allows you to remove copies very easily. It's a simple way to free up space on your Mac.
Cleaning up your hard drive or SSD is important because to have room for virtual memory, you need to keep at least 10% of your disk's capacity free.
Find out how to use Disk Drill and Gemini to free up storage space on your Mac and reduce the chances of it having a kernel panic.

As you can see, kernel panics aren't nearly as worrisome as they first appear. Following the process above, you can quickly fix the problem. Or, better still, you can take steps now to avoid one altogether.
In the Worldwide Developer Conference keynote, Craig Federighi, known to some as Apple's senior vice president of Software Engineering and others as 'Hair Force One,' whipped through a summary of the changes coming later this year to the next version of macOS, dubbed macOS 11.0 Big Sur.
Look and Sound
The most noticeable change to long-time Mac users is a revised Finder interface in Big Sur. Gone is the gray metal window framing that has been around in one shade and texture or another since the Mac first did color. Some bad is good mac os. The new Finder takes some design notes from the Files app in iOS/iPadOS, presenting both title bars and toolbars with plain white backgrounds (or dark backgrounds at your choice). Other window features rely upon different visual indications, such as a Finder window sidebar that's more translucent than ever.
Sidebars in general have received design tweaks in all of Apple's apps, with the goal of reducing clutter and enhancing functionality. The Finder windows are also more gently curved and, courtesy of the plain framing, look less cluttered. Similarly, Apple has tweaked the Dock in Big Sur to be more translucent and has lifted it slightly from the bottom of the screen to float just above it, as in iPadOS. We've seen no word, yet, whether that separation from the screen edge persists for those who prefer the Dock placed on the left or the right.
Apple has also redesigned the icons in the Dock (and in Finder windows). They have subtly enhanced shading and coloring, a shift back to a three-dimensionality that many icons lost in the great Anti-Skeuomorphism Revolution that revamped iOS back in version 7 and migrated to the Mac soon after.
Sheets (those alerts that drop down from the top of a window and demand you do something) now appear accompanied by a dimming of the rest of the display to help you notice that your attention is being requested. They center themselves better in app windows as well.
Accompanying these visual changes is a big push toward interface consistency, with the symbols used for buttons, like Share or Undo buttons, all drawn from a single unified symbol collection. The hope is that developers will be less likely to come up with weird non-standard button icons that leave users guessing what that shape is supposed to mean.
Big Sur wants to tickle your ears as well as your eyes: Apple claims to have updated its system sounds: they may sound familiar (being based on snippets of the earlier sounds) but have been completely regenerated.
Center Enhancements
macOS has long had a hidden interface item stashed behind the right side of the screen that can pop out when some users least expect it: Notification Center. It lists recent notifications you have received and supports useful widgets, like a calendar or a weather widget, which can notify you of upcoming appointments and thunderstorms.
It's unclear to us how many Mac users rely on Notification Center in a big way (many of us don't), but Apple says that Big Sur enhances Notification Center's capabilities in several ways, bringing it more in line with what iOS provides.
First, notifications in Big Sur gain increased interactive capabilities, allowing you to take action on some notifications. For example, pressing and holding a notification can bring up more information, or, in the case of a Mail notification, allow you to begin a reply. Some of that has been available for a while; we'll see if the improvements are compelling. Second, just as in iOS, notifications are now grouped by thread or app, which should bring some order to the chaos of a Notification Center overwhelmed by Slack. You can turn that feature off if desired.
The widgets available to Notification Center have also multiplied. Apple is creating a section of its App Store for third-party developers to stock with their own Notification Center widgets. And, as in iOS 14, those widgets can come in multiple sizes so you can better arrange your Notification Center to suit your needs and your Mac's display size.
Along with Notification Center, Apple has brought Control Center over from iOS. It consolidates many of your menu bar items into a single place so you can access them without opening System Preferences. As in iOS, you can customize Control Center with just the controls you want and dig into specific controls for additional options. For faster access, you can pin your most-used menu items to the top of the menu bar.
How Large of a Change Will Big Sur Be?
For many years, Apple took a 'tick-tock' approach to macOS releases. Leopard and Snow Leopard, Lion and Mountain Lion, Yosemite and El Capitan, Sierra and High Sierra. However, that's fallen away with Mojave and Catalina, and Big Sur seems to be continuing the trend of an independent release that's more than just a refinement of the previous version.

Most obviously, Apple didn't go for a Catalina-related name that would imply a tock release—Big Sur is a mountainous section of California's Central Coast. So much for Avalon, the city on Catalina Island that was our vote for a Catalina-related name.
The bulk of the user-facing changes in Big Sur's apps and related ecosystem aren't particularly large, but that's unsurprising given the elephant in the developer meetings—the switch to Apple silicon (see Adam Engst's coverage in 'Macs Make the Move to ARM with Apple Silicon,' 22 June 2020). Apple has had to recompile every one of Big Sur's apps for Apple silicon, and while the company implies that's easy, it's still a massive undertaking when measured across all the apps that ship with macOS.

Plus, of course, the most significant changes are under the hood in Big Sur: the code necessary to run on Apple's custom chips, the new Rosetta 2 translation environment necessary to support existing apps, and the Universal 2 approach to bundling the code for Intel-based apps and apps written for Apple silicon into a single package.
It's essential that Big Sur works well when it ships later this year, and particularly that it works well on whatever the first Mac is to employ Apple silicon. Catalina has been a troubled release, and even as we head into another macOS development year, we hear from people who continue to worry about upgrading to Catalina. Lots of people will skip Catalina entirely and pin their hopes on Big Sur, so we're hoping that Apple does a much better job of testing and polishing Big Sur than it did with Catalina.
