Had to reboot with Command-R MacOS Recovery and re-installed the OS. I didn't have to do internet recovery, good thing because I did not have Wi-Fi at the time. One problem I did experience - when it came back up I had a very difficult time reconnecting to my Wi-Fi and I had to go through diagnostics to get it to connect. ‎A very easy to use application designed to help you adjust and control the motorized tilt and pan for different Logitech QuickCam Orbit AF and Logitech BCC950 ConferenceCam.

I attended my first WWDC in 2006 to participate in Apple's launch of its DTrace port to the next version of Mac OS X (Leopard). Apple completed all but the fiddliest finishing touches without help from the DTrace team. Even when Apple did meet with us, we had no idea that it was mere weeks away from the finished product being announced to the world. DTrace was a testament both to Apple's engineering acumen as well as its storied secrecy.

At that same WWDC, Apple announced Time Machine, a product that would record file system versions through time for backup and recovery. How was it doing this? We were energized by the idea that there might be another piece of adopted Solaris technology. When we launched Solaris 10, DTrace shared the marquee with ZFS, a new filesystem that was to become the standard against which other filesystems are compared. Key among the many features of ZFS were snapshots that made it simple to capture the state of a filesystem, send the changes around, recover data, etc. Time Machine looked for all the world like a GUI on ZFS (indeed, the GUI that we had imagined but knew to be well beyond the capabilities of Sun).

Players only casino. Of course, Time Machine had nothing to do with ZFS. After the keynote we rushed to an Apple engineer we knew. With shame in his voice he admitted that it was really just a bunch of hard links to directories. For those who don't know a symlink from a symtab, this is the equivalent of using newspaper as insulation: it's fine until the completely anticipated calamity destroys everything you hold dear.

So there was no ZFS in Mac OS X, at least not yet.

2007: Not so fast

A few weeks before WWDC 2007, nerds like me started to lose their minds. Apple really was going to port ZFS to Mac OS X. It was actually going to happen! Beyond the snapshots that would make backups a cinch, ZFS would dramatically advance the state of data storage for Apple users. HFS was introduced in System 2.1 ('System' being what we called 'Mac OS' in the days before operating systems gained their broad and ubiquitous sex appeal). HFS improved upon the Macintosh File System by adding—wait for it—hierarchy! No longer would files accumulate in a single pile; you could organize them in folders. Not that there were many to organize on those 400K floppies, but progress is progress.

That filesystem has limped along for more than 30 years—nudging forward, being rewritten to avoid in-kernel Pascal code (though retaining Pascal-style, length-prefixed strings) but never fully reimagined or reinvented. Even in its most modern form, HFS+ lacks basic functionality around data integrity. Bugs, power failures, and expected and inevitable media failures all mean that data is silently altered. Pray that your old photos are still intact. When's the last time you backed up your Mac? I'm backing up right now, just like I do every time I think about the neglectful stewardship of HFS+.

ZFS was to bring to Mac OS X data integrity, compression, checksums, redundancy, snapshots, and more. But while energizing Mac/ZFS fans, Sun CEO Jonathan Schwartz clumsily disrupted the momentum ZFS had been gathering in Apple's walled garden. Apple had been working on a port of ZFS to Mac OS X. It was planning on mentioning it at the upcoming WWDC. Schwartz, brought into the loop either out of courtesy or legal necessity, violated the cardinal rule of the Steve Jobs-era Apple. Only one person at Steve Jobs' company announces new products: Steve Jobs.

'In fact, this week you'll see that Apple is announcing at [its] Worldwide Developer Conference that ZFS has become the file system in Mac OS 10,' mused Jonathan at a press event, apparently in an attempt to bolster Sun's own credibility.

Less than a week later, Apple spoke about ZFS only when it became clear that a port was indeed present in a developer version of Leopard, albeit in a nascent form. Yes, ZFS would be there, sort of, but it would be read-only, and no one should get their hopes up. How to play craps for dummies.

2008: Ray of hope

By the next WWDC, it seemed that Sun had been forgiven. ZFS was featured in the keynotes, it was on the developer disc handed out to attendees, and it was even mentioned on the Mac OS X Server website. Apple had been working on its port since 2006 and now it was functional enough to be put on full display. I took it for a spin myself; it was really real. The feature that everyone wanted (but most couldn't say why) was coming!

“your computer restarted because of a problem” is typically referred to as kernel panic and it can be caused by both software and hardware issues. If your Mac keeps restarting over and over again, you must first find the root of the problem and then fix it.

In the following lines, we will go over the most common causes for this problem and we will give you options on how to fix it so stay with us if your Mac has started restarting on its own and you have been unable to stop this loop.

“your computer restarted because of a problem press a key or wait a few seconds” loop on Catalina Macbook Pro

Most of our user base has seen this issue on OS Catalina using a Macbook Pro. Though this can occur more rarely on Mac Os Mojave. This leads us to believe that older laptops are more susceptible to this issue. Usually malware doesn’t intervene with your machine at Kernel level.

For starters, let’s go over the most likely causes for the sudden loops and restarts and 4 ways to fix it:

Vmware and lack of sufficient RAM

Using Vmware or any other virtual machine can destabilize your computers performance. Not enough virtual memory (RAM) is oftentimes the cause of many different problems and errors on Mac computers and it is perfectly possible that your Mac is restarting automatically because there isn’t enough RAM for all the processes that it is trying to run.

Outdated OC, plug-ins, or drivers

an outdated OS, driver, or plug-in on your Mac can cause conflicts and be a potential issue for any unexpected restarts.

Conflicting apps

this shouldn’t normally be happening but is still a potential reason for the Mac keeps restarting problem. If you’ve recently downloaded any apps that aren’t optimized properly and are causing conflicts with software that’s already on your Mac, this could be the cause behind the sudden restarts.

Hardware problems

lastly, you shouldn’t forget that there may be some kind of hardware issue on your Mac such as damaged or not properly connected RAM sticks. A hardware issue is a perfectly possible reason for the restarting problem you are facing.

About Kernel Panic

Kernel Panic is when your Mac’s screen goes black and an error message tells you that the computer needs to be restarted. Kernel Panic is an occurrence similar to the Blue Screen of Death for Windows computers and it can indicate lots of different problems.

Below, we will show you possible methods that you can try to fix this problem but note that, since the Kernel Panic problem may have different causes, you may have to go through all the fixing methods until you figure out which one works for you.

Fix 1: Update your OS

As we mentioned above, outdated software could be a possible reason for the sudden crashes of your Mac. This is especially likely if you haven’t installed the latest update for your macOS. Here is how you can fix this:

  1. Open the Apple Menu and select System Preferences.
  2. Next, open Software Update and see if there are any items available for update.
  3. Click on the Update Now button on the latest update that is available for your system.
  4. If you are running an older version of the macOS (for example, High Sierra or Sierra), try upgrading to macOS Catalina – the latest macOS version currently available.

Fix 2: Disconnect peripherals that may be causing the problem

Sometimes, there could be a hardware conflict between your Mac and a peripheral device you’ve connected to the computer. Something as simple as a USB mouse could be causing the sudden restarts on your Mac.

The fix for this problem is very simple – just start disconnecting all devices, one by one, testing to see if the problem still occurs after each disconnected device. This should allow you to figure out if the Kernel Panic is caused by a peripheral and which device is the one that’s problematic. Once you figure it out, just do not connect the peripheral that’s triggering the error to your Mac anymore.

Fix 3: Bypassing startup login items

It is also possible that the Kernel Panic crashes could be caused by a problem login items that prevent you from logging in to your Mac account. Here is a way you may be able to bypass this issue.

1. Start your Mac and enter your password normally but don’t immediately click on the login button.

2. Hold down the Shift button – this will stop any frozen/not-responding apps apps from starting.

3. While holding down Shift, click on the login button and this time the problematic items shouldn’t interfere with the normal functioning of the computer.

Fix 4: Reinstalling macOS

If none of the fixes you have tried so far has worked, this last resort option may resolve your computer restarted because of a problem Catalina problem. To reinstall your macOS, you need to do the following:

  1. Hold down the Option key from your keyboard and restart your Mac.
  2. This should get you to the Recovery screen where you must select the Reinstall macOS option.
  3. Follow the prompts to reinstall the operating system. Note that you will need to have the macOS operating system on a bootable flash memory stick to complete the reinstall. If you don’t have that, you can try to do an Internet Recovery.
  4. To do an Internet Recovery, shut-down your Mac, then press the Power Button to turn on your Mac and immediately after that (before your Mac loads the OS) press and hold-down the Alt/Option + Command + R (make sure you have Internet connection available).
  5. Wait for the loading process to complete – depending on your Internet connection, this may take a while. After everything loads and you are at the recovery screen, select the Reinstall macOS option.
  6. Follow the prompts of the installer and once the re-installation process begins, wait for it to finish. Since this might take quite a while, be sure that, if you are using a Macbook, the computer isn’t running only on batter and is instead connected to the electrical outlet via its power cord. You do not want your Mac to shut down due to low batter in the middle of the re-installation process!
  7. Once macOS reinstalls, all that is left to do is to set set up your preferences – language, country, default Wi-Fi network, etc. Once you are done here, you can now use your Mac once again, hopefully, without experiencing the Kernel Panic loops.
