Errors while updating from 11.7.2 Big Sur to Ventura 13.1 or Monterey 12.1 macOS Big Sur Version 11.7.2 MacBook Pro (16-inch, 2019) 2.6 GHz 6-core Intel Core i7 16 GB 2667 MHz DDR4 Intel UHD Graphics 630 1536 MB I have been trying to complete the newest software update. I have not been updating regularly which I am assuming may be one of my problems. I tried to upgrade to macOS Ventura 13.1, which is what shows when I got to software update in system preferences. I get this error every time I attempt the upgrade. I have restarted, restarted in safe mode, as well as tried to reinstall the Mac OS from recovery mode. None of it works. Always the same result. I have used WiFi and ethernet. I've scoured this board to try and find a fix. When I am try it in recovery mode it gives me this status bar screen: But doesn't move from that. It stays "about 2 hours and 21 minutes remaining" for about 20 minutes and then it gives me this error: I tried to move from Big Sur to Monterey thinking that perhaps I needed to go from 11 to 12 before 13. This is the error I get when I try to upgrade to Monterey: “The operation couldn’t be completed. (PKDownloadError error 8.)" I'm not sure what is wrong and I would love any advice on how to fix this. I appreciate any help! Thanks!

"The file can't be found." on booting... Everytime I start my MacBook Pro (intel chip), I get two error message. Both say "The file can't be found". This has been happening ever since I updated to big sur. I have to click on "OK" (twice) to make them go away. Neither does it tell you what file can't be found. I just updated to Ventura 13.1 and the problem remains. As does the control strip/touch bar issue. Is Apple going downhill...SMH.

Don't worry there is nothing wrong with it.

The error actually means that the App Store has detected a copy of Install macOS High Sierra.app

in your Applications folder. Locate it, move it to the Trash, empty the Trash.

Connect your mac to your router via cable. Restart the mac.

Open Safari, do not use Firefox,

click on the link below,

How to upgrade to macOS High Sierra - Apple Support

Go to Section 4 and click on Get macOS High Sierra

this will redirect you to the App Store High Sierra download page,

it should now say Get or Download

rather than Open which it was saying before.

Go ahead and download it.

Do not use the mac while it is downloading or any other devices that share the same

internet connection.
