macOS constantly crashing and restarting machine

I've maybe a solution to reseting the SMC causing the kernel panic at shutdown... https://support.apple.com/en-us/HT201295

(👉🏻 com.apple.driver.AppleSMC(3.1.9)[EB9D605D-85B1-3506-8B2E-ABD195817A4F]@0xffffff7fa0930000->0xffffff7fa094efff)

🤔 Maybe it's work or not.

So if you have a backup (or not?), you need to start with a clean install and a setting up a new session on Catalina, so:👇🏻

👉🏻 Restart the mac and press up and hold + R to recovery menu,

👉🏻 Go to Disk Utility

https://support.apple.com/en-us/HT208496

👉🏻 At the view menu, select show all devices and select the disk to erase.

👉🏻 Enter a name of the disk such as Macintosh HD and choose APFS and GUID Partition Map.

👉🏻 Click Erase to begin.

👉🏻 Check theses volumes Macintosh HD and Macintosh HD Datas, if it's seems to be OK? Quit the Disk Utility and go to the Catalina Installation.

👉🏻 After that, you need to setting up steps your new user session, not for choosing a backup with Time Machine.

👉🏻 Go to Migration Setup, choose the Time Machine Backup and click to continue.

👉🏻 Select your name, check the content to transfer, and uncheck Apps, Otherfiles and folders and Computer & Network Settings and click to continue to start the transfer.

I hope it's work with the new OS clean for you.

I upgraded from High Sierra to Catalina, 6 Oct on my MacbookPro 2015 15". All seemed fine until Tuesday when firstly I suddenly lost passwords for e-mail accounts logged in Mail and now this morning (11th October) my browsers suddenly stopped working - I can connect to internet (domestic wifi or via iphone) and my VPN can connect but I cannot load pages in Safari, Firefox or Chrome - the browsers say that I am not connected to the internet.

Not only are these problems very irksome the fact that new problems continue to emerge suggests a lack of overall stability.

I went to the Applestore in Stratford and was informed that genius appointments are not available until next Thursday - ditto Covent Garden and Regent Street. Very helpful (not).

Machine now very slow from start up too.

It's too early to say if it's for wait the 10.15.4, we don't know for the moment, the most important is the fix for kernel panic at the next update, Apple has token our reports on this kernel panic on this first version of Catalina and well'see.

Apple working on the fix for Catalina since the kernel panic's reports on this first version, for the moment I stay on Mojave before the fix for Catalina.

Have an iMac I upgraded to 10.15.1 yesterday. Within a few hours I was working in Pages and the computer just shut down. Sent the crash report to Apple. Happened once more when I was checking email, then apparently again after that as it was at the sign in page this morning. Sent the crash report to Apple.

Within two minutes of typing this crashed again. Unfortunately I had Time Machine down for a couple of months so cannot roll back. Definitely did not have any problems prior to yesterdays update to 10.15.1.

After I posted to this Apple support contacted me and I sent them the necessary logs, but no resolution as of yet. I did a re install of Catalina did not work, also read a post regarding sleep mode might be affecting it so I turned everything off in settings including screen saver and manually put the iMac in sleep mode when not using it. This morning left the computer for about 10 minutes open in Safari when I came back it was at the Login screen for Restart because of a problem. Last step if no update this week from Apple will be to do a Time Machine backup with Mojave. Wondering if anyone with this problem has done that and if it is successful. Still a little concerned that this last Catalina update affected the hardware.

I restored to Mojave from Time Machine and all seems to be working. ITunes is still a joke but I’ve given up on the idea of them fixing it.

The fact you you have heard nothing from them on this very serious issue is beyond disappointing.

Apple: you have an obligation to not drop major OS overhauls that aren’t ready for prime time. And further, when your OS fails, you have an obligation to fix it timely and provide hands on customer support. You’ve failed on all counts.

I was seeing the crashes and reboots even when not connected to external display or charger, just using it standalone on battery power. I also saw it when connected to a monitor, it doesn't seem to matter. I reformatted, installed Mojave, and then upgraded to Catalina again after 15.1 released and I haven't seen the issue again. We do have users that have old Mojave installs who have upgraded to 15.1 and are seeing the same problem so it hasn't been fixed.

Two things ... MAC OS 10.15.1 crashes multiple times every time I try to use it.

In Safari, I get a popup window in the middle of the screen that has the verbiage of the website but none of the controls. So usually it can not be closed without closing Safari. A REAL PAIN !!

How did you get back on Mojave? Please.

My late 2017 iMac is unstable after upgrade to Catalina. Programs are not running smoothly and system crashes on shutdown (each time) and sometimes at random moments.
