MacBook Pro Restarting Frequently

Hi all,

Recently, my MacBook Pro has been restarting very frequently. I have attached an image of what I get for an error code every time it restarts. I don't know what this means. I ran a diagnostic test, but it came back saying everything is fine. I have not installed anything new recently (at least not before this happened), nor do I plug anything into my computer, besides the charger of course. Can anyone decipher what this might mean?

I did have to bring this computer to Apple a couple of years ago, but for the life of me I cannot remember why. Some sort of hardware had to get fixed that was relative to my keyboard. I'm not sure, to be entirely honest. Maybe that could be relevant? I'm not sure.

TIA.

Kernel panic, machine check is a serious Hardware error. Your is reporting four instances of a problem in core 0, suggesting serious intel CPU or cache issues.

¿What is the date of your most recent backup, and by what method?

processor problem on a MacBook Pro are generally solved by replacing the mainboard, and you are not likely to get your drive or your files back again.

"On the cloud" is great for sharing photos, but is not a viable backup solution for everything you have. The stuff is not under your control, and is subject to sloppy handling, arbitrary changes in policy, theft, accidental deletion, data loss [are they making frequent backups using best practices?], and discontinuation of the service. It can easily take three days to restore it at ordinary Internet speeds.

If you do not have a recent local, disk-based backup, your computer is like a ticking Time bomb. You are only one disk failure, one crazy software, or one "oops" away from losing EVERYTHING! Drives do not last forever. It is not a question of IF it will fail, only WHEN it will fail. In addition, you never know when crazy software or Pilot Error throws away far more than you intended.

If you are using another direct-to-disk backup method that you prefer, and you currently have a recent disk-based backup, that is great. If not, you should consider using Built-in Time Machine. Take steps to acquire an external drive as soon as possible. If you buy one, a drive 2 to 3 times or larger than your boot drive is preferable for long term trouble-free operation. Do not pay extra for a drive that is fast. (You can get by for a while with a "found" smaller drive if necessary, but it will eventually become annoying).

Attach your external drive and use

System preferences > Time machine ...

... to turn on Time Machine and specify what drive to store your Backups on. It may ask to initialize the new drive, and that is as expected.

Time machine works quietly and automatically in the background, without interrupting your regular work, and only saves the incremental changes (after the first full backup). Time machine backs up every connected drive that is in a Mac compatible format. it can not back up Windows format drives.

Time Machine's "claim to fame" is that it is the backup that gets done, because it does not ruin performance of the rest of the computer while doing its backup operations. You do not have to set aside a "Special Time" when you only do backups. When you need it, your Time machine Backup is much more likely to be there.

Thank you so much for your reply, that doesn't sound good at all.. What could cause such a thing to happen, do you know?

I looked up the cost for replacing motherboards, and the estimates are beyond my reach so I don't think I will be able to get it replaced anytime soon, but I would still like to make sure my computer is backed up. Is it safe for me to continue to use my computer/could it just die on me at any moment?

I think my MacBook is backed up into my iCloud, but I'm not quite sure. My apologies, I'm not very tech savvy. Is there something you would recommend for backing up my computer?

Sorry for asking so many questions, if you can answer any of them it would be much appreciated!

I greatly appreciate your help - I will be getting an external drive ASAP from Apple. Your instructions are immensely helpful. I received a new message this time, when it restarted - I'm assuming it is relatively the same, but it's much longer and detailed than it has been before. This is what I got:

I will not be able to get an external drive until Tuesday.. Is this new message even worse than before? Do you think my computer will make it until Tuesday when I can back it up? Should I refrain from using my computer?

My apologies again for asking a million questions.. I am deeply appreciative of your knowledge and guidance.

<<. x86 CPU CATERR detected. >>

a CAT astrophic error occurred in the CPU. this is a hardware issue.

There are a few things that could force such an error, the most frequently seen is any Third-party Virus scanners, cleaners, optimizers, or a VPN you installed yourself.

I don't believe I have anything like that installed.. I wonder what it could be that is doing that. I think I may bring it into Apple and see what they can tell me when I grab that external drive. Once again, I appreciate your replies! Thank you!!

if that is a processor failure, as it suggests, it may be detected by the User Diagnostic, but typically will not be.

Proper diagnosis REQUIRES reading those panic reports, but Genius Bar technicians are NOT TRAINED to read those reports. They are trained to run their diagnostics overnight, and in the morning return your Mac to you and report "no faults were detected".

The way to proceed toward a fix is to contact Apple support, and work with them to get a specialist to read the information already reported here, and possibly panic reports and other information stored on your computer. Apple support agents can read these discussions, but they do NOT accept Reader's conclusions -- they have a more rigorous process that may involve a MacOS re-install to be certain MacOS was not damaged along the way.

The reason I harp on an external drive and backups, is the boot drive is soldered to the mainboard, and a mainboard replacement will NOT return your drive (and all your files) to you. You MUST have an external, disk-based backup or you lose your files.
